inside tracker, here at doctors 
are running. 

3
00:00:05,200 --> 00:00:07,600
We're always interested in more 
information about our bodies to 

4
00:00:07,600 --> 00:00:10,300
help do what it takes to be a 
strong and healthy as possible 

5
00:00:10,900 --> 00:00:12,600
inside.

00:00:17,200 --> 00:00:19,200
performance, Focus blood work 
analysis. 

9
00:00:19,400 --> 00:00:21,700
One of the things we love most 
is that they give you clear 

10
00:00:21,700 --> 00:00:24,800
simple recommendations on things
you can control to optimize your

00:00:24,800 --> 00:00:27,000
health. 
Things like changes in diet, 

12
00:00:27,000 --> 00:00:29,800
supplements work outs and other 
lifestyle choices. 

13
00:00:30,400 --> 00:00:32,500
So if you're ready to get a 
crystal clear, picture of what's

14
00:00:32,500 --> 00:00:34,800
going on inside your body along 
with science back 

15
00:00:34,800 --> 00:00:36,900

doctors of running everyone, 

20
00:00:57,500 --> 00:01:00,100
welcome to the doctors running 
podcast where we a group of 

21
00:01:00,300 --> 00:01:03,000
Actual Physical Therapy, talk 
about the art and the science 

22
00:01:03,000 --> 00:01:04,900
behind the stuff that we put on 
our feet. 

23
00:01:05,000 --> 00:01:06,500
I'm Matt Klein, I'm joined by 
dr. 

24
00:01:06,500 --> 00:01:08,900
David here. 
David, how you doing doing? 

25
00:01:08,900 --> 00:01:10,400
Well man, how are you? 
Awesome. 

26
00:01:10,400 --> 00:01:13,600
This is gonna be a fun episode. 
We, you know, it's the the fun 

27
00:01:13,600 --> 00:01:16,500
of having such an awesome team, 
we're bouncing in and out of 

28
00:01:16,500 --> 00:01:19,200
who's doing the episode. 
So David and I, we come like 

29
00:01:19,200 --> 00:01:21,200
this, this could be good. 
I know we have some good 

30
00:01:21,200 --> 00:01:23,800
conversations because today 
we're talking about something 

31
00:01:23,800 --> 00:01:27,200
that David and I both look for 
in terms of what is 

32
00:01:27,200 --> 00:01:29,600
responsiveness. 
We've had a lot of readers 

33
00:01:29,600 --> 00:01:31,600
viewers. 
And and listeners reach out and 

34
00:01:31,600 --> 00:01:33,900
go. 
Hey, you know, you talked about 

35
00:01:33,900 --> 00:01:39,200
this term, what is it mean? 
It's funny that that has we were

36
00:01:39,200 --> 00:01:41,200
going to just answer directly 
thought hey, we might as well do

37
00:01:41,200 --> 00:01:43,500
a podcast talk a little bit more
about this because when I've 

38
00:01:43,500 --> 00:01:47,100
looked even through the 
literature, it's very kind of a 

39
00:01:47,108 --> 00:01:49,400
vague term that I think we need 
to explore. 

40
00:01:49,500 --> 00:01:51,700
So that's we're going to dive 
into and of course, our 

41
00:01:51,700 --> 00:01:54,100
subjective is the exact same 
thing. 

42
00:01:54,100 --> 00:01:55,700
Sort of subjective question 
please. 

43
00:01:55,700 --> 00:01:58,400
Answer and whatever Media Forum 
that you're listening watching 

44
00:01:58,400 --> 00:02:02,000
viewing we want to know how to 
You define responsiveness in a 

45
00:02:02,000 --> 00:02:03,200
shoe, what does that mean to 
you? 

46
00:02:03,200 --> 00:02:05,000
What is it? 
How do you define it? 

47
00:02:05,000 --> 00:02:09,900
Let us know in the comments 
below and I'll throw that to dr.

48
00:02:09,900 --> 00:02:12,600
Salah. 
So David, what is responsiveness

49
00:02:12,600 --> 00:02:14,900
mean to you? 
How would you define it? 

50
00:02:15,500 --> 00:02:18,800
Yeah, when I take a look at 
responsiveness, I look at it as 

51
00:02:18,800 --> 00:02:22,900
like this, giant concoction of 
little details that end up 

52
00:02:22,900 --> 00:02:25,800
responding to this shoe and what
you get from the shoe. 

53
00:02:25,800 --> 00:02:29,500
And when I look at it, in the 
most literal sense is, when I 

54
00:02:29,500 --> 00:02:33,000
want this shoe, You to respond, 
does it respond to the forces 

55
00:02:33,000 --> 00:02:36,400
that I want to put on it? 
So when I'm asking that shoe or 

56
00:02:36,400 --> 00:02:39,100
when I'm asking my body like, 
okay now I want something from 

57
00:02:39,100 --> 00:02:41,800
this. 
Shoot can it deliver and that 

58
00:02:41,800 --> 00:02:44,300
isn't just the midsole that's 
not just a plate. 

59
00:02:44,300 --> 00:02:47,800
There's a million things that go
into making a shoe quote, 

60
00:02:47,800 --> 00:02:52,400
unquote responsive but I take a 
look at it and just how well 

61
00:02:52,400 --> 00:02:54,400
does this shoe respond to load? 
You know, the harder you're 

62
00:02:54,400 --> 00:02:58,500
putting down the quicker? 
You move it and the more you're 

63
00:02:58,600 --> 00:03:01,200
trying to get from it from You 
and your own body? 

64
00:03:01,200 --> 00:03:03,100
Like how well does that she'll 
respond? 

65
00:03:03,800 --> 00:03:07,500
Yeah, I think we mentioned this 
off are earlier, but David gets 

66
00:03:07,500 --> 00:03:10,200
all credit for going. 
Hey, he's going to Define this 

67
00:03:10,200 --> 00:03:13,000
as how is she responds to look 
because what I think of 

68
00:03:13,000 --> 00:03:15,000
responsiveness. 
And what I'm usually meaning is 

69
00:03:15,400 --> 00:03:17,700
if I'm going to push the pace 
and start putting some force in 

70
00:03:17,700 --> 00:03:20,100
the shoe, how much of that? 
Am I getting back, right? 

71
00:03:20,100 --> 00:03:23,800
So if I have something like, you
know, a very light Snappy racing

72
00:03:23,800 --> 00:03:26,800
flat that when I start picking 
up the pace, it feels good. 

73
00:03:26,800 --> 00:03:30,000
It's popping off the ground. 
I feel like I'm not having to 

74
00:03:30,100 --> 00:03:34,200
Fight the shoe, a moot like it's
moving with me and it's if even,

75
00:03:34,200 --> 00:03:36,600
even give me some it, like 
energy, but it's not the right 

76
00:03:36,600 --> 00:03:41,200
term, but it feels like it's 
helped me kick along, whereas a 

77
00:03:41,200 --> 00:03:44,700
shoe that is mushy, something 
that kind of you compress into. 

78
00:03:44,700 --> 00:03:47,000
It doesn't bounce back and we'll
have some more scientific term 

79
00:03:47,000 --> 00:03:49,500
for this in just a second, but 
it's kind of like, hey, it's 

80
00:03:49,500 --> 00:03:51,000
really cushion. 
But it doesn't bounce back. 

81
00:03:51,000 --> 00:03:53,400
It doesn't work well for going 
fast. 

82
00:03:53,400 --> 00:03:55,600
It just good for easy stuff. 
That's a shoe that I would 

83
00:03:55,600 --> 00:03:59,800
Define as not responsive. 
It's and it, but that's probably

84
00:03:59,800 --> 00:04:01,400
not We are going to be using 
that shoe. 

85
00:04:01,400 --> 00:04:05,000
Hopefully, so you mention this, 
and this is great because 

86
00:04:05,000 --> 00:04:08,500
there's Al as always. 
And if your listeners watching, 

87
00:04:08,500 --> 00:04:10,400
you should know that we're not 
trying to make things 

88
00:04:10,400 --> 00:04:12,000
complicated. 
They often are. 

89
00:04:12,200 --> 00:04:14,300
So there's a lot of pieces that 
go into this. 

90
00:04:14,300 --> 00:04:17,000
It's not just one factor. 
And I think the reason I bring 

91
00:04:17,000 --> 00:04:19,200
that up, is because we've talked
about, you know, shoe 

92
00:04:19,200 --> 00:04:23,700
resiliency, which the or foam 
resiliency, which Farmers Ilyas 

93
00:04:23,700 --> 00:04:25,800
resiliency specifically is 
defined. 

94
00:04:25,800 --> 00:04:30,700
As when you deform a material 
how much does Does it bounce 

95
00:04:30,700 --> 00:04:32,400
back? 
Bounce backs up the right word, 

96
00:04:32,400 --> 00:04:37,200
but how, how much is it reform? 
So if you compress a foam and it

97
00:04:37,200 --> 00:04:42,300
risks in it reforms like 85%, 
87%, you would have 87% 

98
00:04:42,300 --> 00:04:46,300
resiliency right? 
Somebody some foam biomechanism.

99
00:04:46,300 --> 00:04:49,200
Please correct me if I have 
misinterpreted that but the 

100
00:04:49,200 --> 00:04:51,300
reason I'm using that number is 
because there were some studies 

101
00:04:51,300 --> 00:04:55,000
a couple years ago you know Jeff
Burns we've had on the podcast 

102
00:04:55,000 --> 00:04:58,100
has been really good had 
pardoned, some of those Hooch 

103
00:04:58,100 --> 00:05:00,500
camera and a couple other 
phenomenal buy America This were

104
00:05:00,500 --> 00:05:03,300
looking at the Nike Vapor flying
other shoes and found that the 

105
00:05:03,300 --> 00:05:07,200
vapor fly had an 80. 
Correct me if I'm wrong, 87%, 

106
00:05:07,200 --> 00:05:10,400
resiliency insert in my you're 
making it, I think is there and 

107
00:05:10,400 --> 00:05:11,800
think it might have actually 
been a little higher. 

108
00:05:12,000 --> 00:05:15,100
Was it? 
87 89, 88, something like that. 

109
00:05:16,200 --> 00:05:19,200
The OG, an original, the 
original, the original, okay? 

110
00:05:19,200 --> 00:05:21,100
Yes, like this to me is p backs 
numbers. 

111
00:05:21,100 --> 00:05:23,400
I thought they were getting 
into, like the low 90s that they

112
00:05:23,400 --> 00:05:25,700
are, they are. 
So that's the, I a regional 

113
00:05:25,700 --> 00:05:29,800
Vapor fly the new stuffs going 
higher, the Endorphin Elites, 

114
00:05:29,800 --> 00:05:30,200
right? 
Right? 

115
00:05:30,200 --> 00:05:34,700
Which we just got our hands on 
is 95%, so that's, that's crazy,

116
00:05:34,700 --> 00:05:36,500
right? 
That means like 94 percent five 

117
00:05:36,500 --> 00:05:38,800
percent of the compressions 
going to get come back at you. 

118
00:05:38,800 --> 00:05:41,200
Which that's, and that feels 
like this, right? 

119
00:05:41,200 --> 00:05:43,800
This is not a review of this 
shoe, but this shoe is super 

120
00:05:43,800 --> 00:05:46,300
fun. 
Not the most durable, but super 

121
00:05:46,300 --> 00:05:48,000
fun and bounces along really, 
really well. 

122
00:05:48,000 --> 00:05:53,500
So, you know, but just because 
the foam bounces back that much 

123
00:05:53,500 --> 00:05:56,200
doesn't necessarily mean it's 
response because there's other 

124
00:05:56,200 --> 00:05:59,800
parts of the shoe that can 
either add or detract from this.

125
00:05:59,800 --> 00:06:02,500
So Other components which we 
talked about foam, right? 

126
00:06:02,500 --> 00:06:05,700
So the how much it kind of Pops 
back or the, the technical term 

127
00:06:05,700 --> 00:06:09,700
is resiliency, what other 
components of the shoe? 

128
00:06:09,700 --> 00:06:12,400
Do you think add to 
responsiveness? 

129
00:06:12,800 --> 00:06:13,900
Yeah. 
And when we take a look at 

130
00:06:13,908 --> 00:06:16,900
responsiveness to some degree, 
I'm also it's like the art and 

131
00:06:16,900 --> 00:06:19,900
the science, right? 
The science is the resiliency. 

132
00:06:19,900 --> 00:06:22,400
The longitudinal bending 
stiffness. 

133
00:06:22,400 --> 00:06:24,300
All kinds of components that go 
in. 

134
00:06:24,300 --> 00:06:27,400
That are the scientific Parts, 
but the end of the day it still 

135
00:06:27,400 --> 00:06:29,800
has to be a shoe. 
And it still has to be something

136
00:06:29,800 --> 00:06:33,700
that You want to run in, but I 
think I'll I'm glad you brought 

137
00:06:33,700 --> 00:06:36,300
up the Endorphin Elite, because 
I've gotten or friend Elite 

138
00:06:36,300 --> 00:06:37,900
right next to me. 
And I've gotten into it from Pro

139
00:06:37,900 --> 00:06:42,900
3 right next to me. 
And I think not a Saucony plug 

140
00:06:42,900 --> 00:06:44,400
here. 
It's just, I think it's a good 

141
00:06:44,400 --> 00:06:47,500
example of them doing something 
very different with two shoes in

142
00:06:47,500 --> 00:06:50,800
the same category, both 
responsive, but in different 

143
00:06:50,800 --> 00:06:54,900
ways and I will say that like, 
for me, the Endorphin Elite is 

144
00:06:54,900 --> 00:06:57,900
more responsive than the 
Endorphin Pro 3 and here's why 

145
00:06:58,400 --> 00:07:01,800
so they did update the midsole, 
From a resilient standpoint that

146
00:07:01,800 --> 00:07:04,700
is a little bit higher but if 
you look at the geometric 

147
00:07:04,700 --> 00:07:09,300
configuration of the shoes as 
well the Endorphin Pro 3 has a 

148
00:07:09,300 --> 00:07:14,200
much more gradual like speed 
roll devil, you know, rocker 

149
00:07:14,200 --> 00:07:16,300
profile whatever we want to call
it. 

150
00:07:16,600 --> 00:07:19,100
When you look at the Endorphin 
Elite you have a very sharp 

151
00:07:19,100 --> 00:07:23,300
toast bring up front and the 
bevel in the heel is actually 

152
00:07:23,300 --> 00:07:25,000
pretty comparable between the 
two. 

153
00:07:25,300 --> 00:07:26,600
There's not too much of a 
difference. 

154
00:07:26,600 --> 00:07:29,700
So you're healing mid-foot 
transitions are similar but you 

155
00:07:29,700 --> 00:07:33,500
have a A really fast poppy, 
four-foot transition in the 

156
00:07:33,500 --> 00:07:36,800
Endorphin Elite compared to the 
Endorphin, Pro 3. 

157
00:07:37,300 --> 00:07:40,000
And so we're one is a little bit
more of a Cadence type shoe. 

158
00:07:40,000 --> 00:07:42,100
The other one just really wants 
you to send it. 

159
00:07:42,100 --> 00:07:45,500
Like you just want you to just 
pop off at four foot and go and 

160
00:07:45,500 --> 00:07:48,700
so some of it is a feeling, but 
when we take a look at it, they 

161
00:07:48,700 --> 00:07:50,800
both have carbon plates. 
But you don't necessarily have 

162
00:07:50,800 --> 00:07:52,700
to have a stiffening agent in 
there. 

163
00:07:52,700 --> 00:07:54,200
You can still have a responsive 
shoe. 

164
00:07:54,700 --> 00:07:56,700
Sometimes flexibility can 
actually be your friend 

165
00:07:57,100 --> 00:08:00,000
depending on what you're wanting
for me. 

166
00:08:00,100 --> 00:08:01,800
Sfm on the track, doing some 
speed work. 

167
00:08:01,800 --> 00:08:04,400
Ironically I actually don't 
really like a plate in my shoe 

168
00:08:04,900 --> 00:08:06,900
so I can see that's been working
really well for me. 

169
00:08:07,300 --> 00:08:10,300
We're on the same page tonight. 
This is this is awesome. 

170
00:08:10,500 --> 00:08:14,000
Yeah I knew what he was going to
grab so I kind of just for those

171
00:08:14,000 --> 00:08:19,000
who are listening. 
It just pulled up the the Topo 

172
00:08:19,000 --> 00:08:22,900
Cyclone to which has been a 
phenomenal shoe off topic. 

173
00:08:23,200 --> 00:08:25,900
This has been a really great 
shoe for a couple high schoolers

174
00:08:25,900 --> 00:08:27,700
that I've been working with 
that. 

175
00:08:27,700 --> 00:08:30,100
You know. 
They we you know, we have our On

176
00:08:30,100 --> 00:08:31,900
and off with Orthotics. 
And, you know, this review, you 

177
00:08:31,900 --> 00:08:33,799
listen this. 
But they've got some 

178
00:08:33,799 --> 00:08:36,600
biomechanical issues that they 
were born with where they really

179
00:08:36,600 --> 00:08:38,400
need to have a little orthotic 
there. 

180
00:08:38,799 --> 00:08:41,799
And a lot of racing shoes won't 
take that and this the Topo 

181
00:08:41,799 --> 00:08:44,500
Cyclone to actually will. 
So it's been a really good 

182
00:08:44,500 --> 00:08:48,000
comment erasing option that's 
also has a little wider fit can 

183
00:08:48,000 --> 00:08:50,600
handle something like that but 
it's it's super flexible. 

184
00:08:50,600 --> 00:08:53,100
Stop played it but man this 
thing moves right? 

185
00:08:53,100 --> 00:08:55,700
The pebax foam, it's a little 
lower to the ground. 

186
00:08:55,700 --> 00:08:58,100
Not the highest stack height but
it's super light. 

187
00:08:58,100 --> 00:08:59,900
What is it under seven ounces, 
right? 

188
00:09:00,200 --> 00:09:03,500
Yeah, yeah, so I think so 6.8 or
something like that this is this

189
00:09:03,500 --> 00:09:06,400
is a great example because 
you're mentioning you mention a 

190
00:09:06,400 --> 00:09:09,000
couple things you're going, hey,
we talked about the foam which 

191
00:09:09,000 --> 00:09:12,000
can certainly influence this and
it doesn't necessarily mean the 

192
00:09:12,000 --> 00:09:14,500
Supersoft Foams, like the super 
soft bouncy. 

193
00:09:14,500 --> 00:09:16,700
Phones are initially going to be
the most responsive, right? 

194
00:09:16,700 --> 00:09:18,600
In certain shoes that can 
actually be a little mushy 

195
00:09:19,000 --> 00:09:20,800
sometimes having things be a 
little bit firmer. 

196
00:09:20,800 --> 00:09:25,300
Like so for the Endorphin Pro 3 
and the Endorphin Elite, I find 

197
00:09:25,300 --> 00:09:28,800
the Endorphin. 
Pro 3, much softer of a Shoe, 

198
00:09:28,800 --> 00:09:30,800
Right versus the indoor. 
And really it was a little bit 

199
00:09:30,800 --> 00:09:35,300
firmer but that the like 
responsiveness of the elite is, 

200
00:09:35,300 --> 00:09:39,500
is for me personally higher. 
So it's again subject if you're 

201
00:09:39,500 --> 00:09:41,700
going to see how you respond to 
it. 

202
00:09:41,900 --> 00:09:44,500
But another thing you'll have to
look at is what's the geometry 

203
00:09:44,500 --> 00:09:46,000
of the shoe, right? 
Is it rolling? 

204
00:09:46,000 --> 00:09:47,400
You forward? 
Is it? 

205
00:09:47,400 --> 00:09:50,200
What's how aggressive is, it is 
working with your mechanics? 

206
00:09:50,400 --> 00:09:52,000
And then there's also the 
flexibility or bending 

207
00:09:52,000 --> 00:09:56,400
stiffness, do you work well with
the super stiff Snappy shoe, or 

208
00:09:56,400 --> 00:09:58,900
do you want something that's 
more flexible and pulls, you 

209
00:09:58,900 --> 00:10:01,000
forward, right? 
That's That's going to vary. 

210
00:10:01,000 --> 00:10:05,400
So it's not one factor, it's the
combination of factors. 

211
00:10:05,400 --> 00:10:08,700
And before I dive into our by 
mechanics, is there anything 

212
00:10:08,700 --> 00:10:11,200
else you think from the shoe 
that can influence 

213
00:10:11,200 --> 00:10:13,200
responsiveness because you have 
that? 

214
00:10:13,200 --> 00:10:16,300
We've got foam geometry 
stiffness. 

215
00:10:16,600 --> 00:10:21,700
I missing anything, we talked 
about I mean, even our sieves 

216
00:10:21,700 --> 00:10:24,600
and councils and can yeah, still
do that. 

217
00:10:24,600 --> 00:10:25,900
Yeah, oh yeah. 
Yeah. 

218
00:10:25,900 --> 00:10:30,400
Traction definitely, and in a 
weird way like so, Sometimes 

219
00:10:30,400 --> 00:10:33,500
you'll see a flatter outsole on 
a shoe because it'll give you a 

220
00:10:33,500 --> 00:10:36,100
softer perception of. 
Yeah, ground underneath. 

221
00:10:36,100 --> 00:10:39,300
You like what field of foam or 
right versus like a thicker 

222
00:10:39,400 --> 00:10:42,000
Rubber outsole? 
And again, this is going to be a

223
00:10:42,000 --> 00:10:45,000
more of a personal preference 
for different situations but a 

224
00:10:45,008 --> 00:10:49,100
lot of these road racing shoes 
or roads Pacific shoes, they 

225
00:10:49,100 --> 00:10:52,500
have these thin outsoles on 
them, you know, like they 

226
00:10:52,500 --> 00:10:56,700
basically like almost act like 
trying to think of the word, but

227
00:10:56,700 --> 00:10:59,000
it almost like it like 
compresses a little bit and grab

228
00:10:59,000 --> 00:11:03,200
the road, you know? 
Versus like then being like this

229
00:11:03,200 --> 00:11:06,300
thick rubber where it's like, 
okay, I am going to attack and 

230
00:11:06,300 --> 00:11:10,000
Claw at the ground. 
You know, another example, I 

231
00:11:10,000 --> 00:11:12,400
guess would be the Evo ride that
I'm holding right here, very 

232
00:11:12,400 --> 00:11:19,100
flat outsole. 
Very good for road but yeah I 

233
00:11:19,100 --> 00:11:21,900
would say the geometry, bending 
stiffness, all that's there and 

234
00:11:21,900 --> 00:11:25,000
depending on the surface that 
you're on, for me, like on the 

235
00:11:25,000 --> 00:11:27,800
track, I actually like a little 
bit of a lower profile and I 

236
00:11:27,800 --> 00:11:31,500
mean, it was on accident. 
Didn't this was not planned, but

237
00:11:31,500 --> 00:11:35,700
I did a sixteen by 400 workout 
in the Saucony ride. 16 the 

238
00:11:35,700 --> 00:11:37,700
other day. 
Yeah, pieces were pretty 

239
00:11:37,700 --> 00:11:38,900
respectable. 
I think. 

240
00:11:39,200 --> 00:11:41,600
Yeah, and it responded. 
It did not, it did. 

241
00:11:41,600 --> 00:11:44,600
Alright, you know, and I mean 
it's a relatively firmer foam. 

242
00:11:44,600 --> 00:11:46,200
A little bit snappier in the 
forefoot. 

243
00:11:46,200 --> 00:11:50,200
Like, it was heavy for the track
for me, but like, but it still 

244
00:11:50,200 --> 00:11:51,200
worked. 
Yeah. 

245
00:11:51,200 --> 00:11:54,200
It's so it's a lighter shoe, 
though, for a daily trainer 

246
00:11:54,200 --> 00:11:55,400
slider, and they just updated 
it. 

247
00:11:55,400 --> 00:11:58,200
Think the midst, the insole, I'm
sorry with power and plus. 

248
00:11:58,200 --> 00:12:02,600
So that's the other It is, 
there's also a subjective peace 

249
00:12:02,600 --> 00:12:05,800
to this of what you're going to.
Like, I think the Saucony write 

250
00:12:05,800 --> 00:12:08,700
16, as a great example is always
to me been that shoe that can 

251
00:12:08,700 --> 00:12:12,400
handle a variety of cases, just 
because it is always been a 

252
00:12:12,400 --> 00:12:15,300
little lighter, the volume of 
the shoes, a little lower. 

253
00:12:15,300 --> 00:12:17,400
So it feels like there's less to
carry. 

254
00:12:17,400 --> 00:12:21,000
Whereas I think a larger shoe 
sometimes doesn't always feel 

255
00:12:21,000 --> 00:12:22,500
like that. 
Sometimes it does, sometimes it 

256
00:12:22,500 --> 00:12:25,600
doesn't, but it's also got that 
fat slightly firmer phone. 

257
00:12:25,600 --> 00:12:27,200
Feels good. 
When you're picking up the pace,

258
00:12:27,200 --> 00:12:29,800
it's not mushy, it's not Bare 
Bones. 

259
00:12:30,000 --> 00:12:33,600
But it can still grip and move, 
and that's kind of what the ride

260
00:12:33,600 --> 00:12:36,200
has always done. 
So that the audio, so you're 

261
00:12:36,200 --> 00:12:38,900
bringing out, this is the audio.
So, yes, it's taking a look at 

262
00:12:38,900 --> 00:12:41,200
stiffening agents to and 
creating that launched no 

263
00:12:41,200 --> 00:12:43,600
bending stiffness. 
Like, doesn't necessarily have 

264
00:12:43,600 --> 00:12:46,400
to have a full-on plate, to have
that either. 

265
00:12:46,400 --> 00:12:50,100
And so yeah, look at the audio. 
They have that plastic shank and

266
00:12:50,100 --> 00:12:51,900
then it kind of has that little 
Fork design. 

267
00:12:51,900 --> 00:12:55,000
So you get a little bit softer 
plant through the mid part of 

268
00:12:55,000 --> 00:12:58,100
the forefoot, you know, on the 
actual planner pressure part. 

269
00:12:58,200 --> 00:12:59,700
Yeah. 
And then you kind of get a 

270
00:12:59,708 --> 00:13:00,900
little Bit of like a little 
side. 

271
00:13:00,900 --> 00:13:05,500
Well almost, yeah, it's kind of 
cool, but yeah, very Snappy very

272
00:13:05,500 --> 00:13:07,700
firm you know. 
Very yeah. 

273
00:13:07,800 --> 00:13:10,500
So, it's again, going to be a 
combination of factors. 

274
00:13:10,500 --> 00:13:14,700
So it's going to be Hey, how 
well does the foam bounce back? 

275
00:13:14,700 --> 00:13:17,600
And that can be either a soft or
firm foam which I'm going to go 

276
00:13:17,600 --> 00:13:20,600
into just a second with I think 
really adds to responsiveness 

277
00:13:21,000 --> 00:13:23,800
Geometry. 
How rocker does it move you in 

278
00:13:23,800 --> 00:13:24,900
it? 
Does it work with your 

279
00:13:24,900 --> 00:13:27,800
mechanics? 
The stiffness, or flexibility 

280
00:13:27,800 --> 00:13:30,700
shoe, which again is going to 
depend on What you're using it 

281
00:13:30,700 --> 00:13:32,400
for, and I agree with you. 
I like something a little bit 

282
00:13:32,400 --> 00:13:34,200
more flexible. 
When I'm, when I'm starting to 

283
00:13:34,200 --> 00:13:36,700
really move on track. 
I want something just a little 

284
00:13:36,700 --> 00:13:38,400
bit Fleck. 
More flexible when I'm kind of 

285
00:13:38,400 --> 00:13:41,000
trying to hold and be efficient 
over a long period, a little 

286
00:13:41,000 --> 00:13:44,100
stiffer can be helpful, but it's
got a match, you mentioned 

287
00:13:44,100 --> 00:13:48,900
traction and outsole which also 
do that the insole as well adds 

288
00:13:48,900 --> 00:13:52,800
to the midsole, really? 
Because it's just that perceived

289
00:13:52,900 --> 00:13:55,000
thing underfoot. 
I also want to talk about the 

290
00:13:55,300 --> 00:13:59,200
rate of how quickly all the shoe
compresses and bounces back 

291
00:13:59,200 --> 00:14:02,000
because I great Sample. 
This is I have the Adidas Prime 

292
00:14:02,000 --> 00:14:06,000
X strung with me and it's, it's 
an interesting shoe. 

293
00:14:06,000 --> 00:14:09,500
What I buy it again. 
No, but I have it now. 

294
00:14:09,500 --> 00:14:13,300
So it, there's so much. 
Midsole, there's so much volume,

295
00:14:13,300 --> 00:14:13,900
you think? 
Yeah. 

296
00:14:13,900 --> 00:14:17,900
There's tons of this newer foam.
The Light Strike Pro, there's 

297
00:14:17,900 --> 00:14:21,800
two layers, there's energy, 
rods, and energy blades in here.

298
00:14:21,800 --> 00:14:24,200
So super do first, if it's 
rocker all the stuff. 

299
00:14:24,200 --> 00:14:27,100
But I find this to be a bouncy 
ride. 

300
00:14:27,108 --> 00:14:30,200
I don't find it to be a 
responsive ride because Cuz when

301
00:14:30,200 --> 00:14:32,900
I think of responsibility 
usually thinking, like, hey if 

302
00:14:32,900 --> 00:14:36,100
I'm really trying to pick up the
pace, does this thing bounce 

303
00:14:36,100 --> 00:14:39,400
with me and for longer efforts 
when I'm doing like a temple 

304
00:14:39,400 --> 00:14:41,600
run, this is good. 
But if I try to do for hundreds 

305
00:14:41,600 --> 00:14:45,100
in this, I would die the foam. 
Just with how much there is and 

306
00:14:45,100 --> 00:14:48,700
how big the shoe is. 
It just doesn't move as quickly 

307
00:14:48,700 --> 00:14:51,200
when I bounce into it. 
There's so much stuff. 

308
00:14:51,200 --> 00:14:54,600
It feels like it takes a second 
to come back because there's so 

309
00:14:54,600 --> 00:14:57,500
much foam and that's why again. 
More isn't better. 

310
00:14:57,500 --> 00:14:59,500
You have to find what works for 
you compared to something like 

311
00:14:59,500 --> 00:15:02,000
the toe. 
Cyclone to which Laura stack 

312
00:15:02,000 --> 00:15:05,200
still pebax. 
That for me feels way more 

313
00:15:05,200 --> 00:15:08,800
responsive because it's got that
Snappy roll with a little more 

314
00:15:08,800 --> 00:15:12,000
flexibility. 
It's going to mean different 

315
00:15:12,000 --> 00:15:13,900
things to different people. 
I know plenty of people are 

316
00:15:13,900 --> 00:15:16,100
like, oh, this is, you know, the
prime X strong is the most 

317
00:15:16,100 --> 00:15:18,700
responsive think I've ever felt 
like, that's great, right? 

318
00:15:18,900 --> 00:15:21,600
But it really comes back to how 
you defined. 

319
00:15:21,600 --> 00:15:24,000
It going. 
It's how the shoe response to 

320
00:15:24,000 --> 00:15:27,700
the load, which is going to vary
depending on the person, right? 

321
00:15:27,700 --> 00:15:29,800
There's so now we've talked 
about this shoe. 

322
00:15:29,900 --> 00:15:32,000
Shoe. 
And this is why it's so good 

323
00:15:32,000 --> 00:15:34,900
that we have multiple reviewers 
on each on each shoe is because 

324
00:15:34,900 --> 00:15:37,000
each person is going to respond 
differently, right? 

325
00:15:37,000 --> 00:15:38,700
Because David you've run in the 
premix before. 

326
00:15:38,700 --> 00:15:42,000
How would you define that as a 
responsive shoe or would you say

327
00:15:42,300 --> 00:15:45,000
that's not necessarily what you 
might be looking for? 

328
00:15:45,700 --> 00:15:48,200
If you're gonna I would say it's
responsive. 

329
00:15:48,200 --> 00:15:52,200
Yeah, I it was a scary shoe. 
Yeah, it scares you. 

330
00:15:53,000 --> 00:15:57,100
It was it was a shoe that I was 
a little worried about breaking 

331
00:15:57,100 --> 00:15:58,400
an ankle on. 
Yeah. 

332
00:16:00,100 --> 00:16:04,300
Especially on the cambered roads
and things like that, but II 

333
00:16:04,300 --> 00:16:09,600
didn't push the shoe down into 
like those 5K 10K like Paces. 

334
00:16:10,000 --> 00:16:13,600
You know, I really only kept it 
at maybe half marathon pace. 

335
00:16:13,600 --> 00:16:16,200
So I wasn't able to when I 
tried. 

336
00:16:16,200 --> 00:16:18,200
I was just like this is just you
just respond. 

337
00:16:19,500 --> 00:16:22,000
There's a lot going on. 
Yeah, I'm not saying it's bad 

338
00:16:22,000 --> 00:16:23,100
shoe. 
Just saying it now. 

339
00:16:23,100 --> 00:16:27,000
And yeah, it wasn't what I 
wanted if I was looking for a 

340
00:16:27,000 --> 00:16:30,200
responsive shoe for me. 
Right? 

341
00:16:30,200 --> 00:16:32,200
And some people like that. 
More Nimble feel. 

342
00:16:32,200 --> 00:16:35,200
Yeah, and for them like that 
traditional racing flat, you 

343
00:16:35,208 --> 00:16:38,900
were describing real low, you 
have relatively flexible. 

344
00:16:38,900 --> 00:16:43,000
Not a lot of foam on it with a 
decent amount of traction Under 

345
00:16:43,000 --> 00:16:45,700
Foot, you know, like some people
they that connection to the 

346
00:16:45,700 --> 00:16:48,900
ground to them is the response 
or like they're super light on 

347
00:16:48,900 --> 00:16:51,500
foot, they're just like, let's 
go, you know? 

348
00:16:51,500 --> 00:16:54,200
And then sometimes if someone 
maybe we'll see, maybe their 

349
00:16:54,200 --> 00:16:56,400
Cadence is a little bit slower, 
they don't, they're not quite as

350
00:16:56,400 --> 00:16:58,900
Nimble, and they like to use 
there. 

351
00:16:59,600 --> 00:17:02,500
Joints as like these long lever 
arms, to really kind of pull 

352
00:17:02,500 --> 00:17:05,300
themselves, you know? 
For it like they might respond a

353
00:17:05,308 --> 00:17:08,700
lot better to some of these 
higher ones to depending on, you

354
00:17:08,700 --> 00:17:10,300
know, how fast we're trying to 
go. 

355
00:17:10,300 --> 00:17:12,200
But right. 
Yeah. 

356
00:17:12,200 --> 00:17:16,500
So that goes into, who, what 
does responsiveness mean to each

357
00:17:16,500 --> 00:17:17,800
person? 
So just going to kind of be a 

358
00:17:17,800 --> 00:17:20,300
couple of mechanics, where 
different people might respond 

359
00:17:20,300 --> 00:17:22,300
differently. 
One of them is obviously 

360
00:17:22,300 --> 00:17:24,099
Cadence, right? 
And you're the length of your 

361
00:17:24,099 --> 00:17:26,200
lover of your lover, right? 
How long your legs are 

362
00:17:26,599 --> 00:17:28,200
different. 
People move in different ways. 

363
00:17:28,200 --> 00:17:31,100
We're seeing more companies. 
To go you know it do different 

364
00:17:31,100 --> 00:17:33,100
shoes work differently. 
Do we need to have two different

365
00:17:33,100 --> 00:17:35,100
models models with your 
different people? 

366
00:17:35,600 --> 00:17:37,500
How each person is going to 
respond. 

367
00:17:37,500 --> 00:17:40,500
We're still trying to learn and 
no Asics just to throw a name 

368
00:17:40,500 --> 00:17:42,400
out. 
Was trying the Cadence forces 

369
00:17:42,700 --> 00:17:45,200
stride model. 
I think that may have worked for

370
00:17:45,200 --> 00:17:47,600
some people may not have worked 
for others, because different 

371
00:17:47,600 --> 00:17:50,200
people said, hey, I've got a 
super high Cadence, and I'm 

372
00:17:50,200 --> 00:17:52,200
really, really enjoying the sky.
And other people said, I have a 

373
00:17:52,200 --> 00:17:54,000
super long stride. 
I'm loving the edges. 

374
00:17:54,000 --> 00:17:57,100
Like, okay, well, maybe we need 
to I see where they're going. 

375
00:17:57,100 --> 00:17:58,100
I see what they're trying, 
right? 

376
00:17:58,100 --> 00:17:59,200
There's still some work that 
needs. 

377
00:17:59,400 --> 00:18:03,000
Be that they still had two solid
shoes, the gay people options. 

378
00:18:03,500 --> 00:18:06,400
There is another factor that I 
don't know. 

379
00:18:06,400 --> 00:18:10,200
It's much harder dresses like 
the inherent stiffness of the 

380
00:18:10,200 --> 00:18:14,100
person, right? 
So how when they land, it's not 

381
00:18:14,100 --> 00:18:15,700
just the shoe, it's the person's
body. 

382
00:18:15,700 --> 00:18:18,300
That's going to help them. 
Perceive what they feel 

383
00:18:18,300 --> 00:18:20,800
underfoot, which is why we have 
a variety of reviewers, write 

384
00:18:20,800 --> 00:18:26,100
something that I might respond 
well to David Nathan, Andrea 

385
00:18:26,100 --> 00:18:28,700
Bach. 
BJ, any of our team members may 

386
00:18:28,700 --> 00:18:31,400
not have the The same response 
due to stuff like joint 

387
00:18:31,400 --> 00:18:34,500
stiffness or muscles muscles. 
Muscular tension is stiffness or

388
00:18:34,500 --> 00:18:37,500
how quickly your nervous system 
responds when you hit the 

389
00:18:37,500 --> 00:18:40,200
ground. 
Some people like me a super soft

390
00:18:40,200 --> 00:18:42,600
shoe. 
I don't do superhot in I've 

391
00:18:42,600 --> 00:18:46,100
honestly really struggle with 
shoes, like the vapor fly to get

392
00:18:46,100 --> 00:18:49,700
them to work for me because the 
foam at least, well, the recent 

393
00:18:49,700 --> 00:18:51,600
one, I actually tried on was a 
little firmer and I was like, 

394
00:18:51,600 --> 00:18:56,000
oh, I kind of like that, but 
some of the original ones had so

395
00:18:56,000 --> 00:18:58,600
much bounce to them. 
And they were so soft that I 

396
00:18:58,600 --> 00:19:02,200
just kind of And then I couldn't
pop out of them because I don't 

397
00:19:02,200 --> 00:19:05,400
tend to be as stiff. 
Whereas I might argue David. 

398
00:19:05,400 --> 00:19:09,000
You correct me if I'm wrong, you
got much more Snappy mechanics, 

399
00:19:09,000 --> 00:19:12,100
so that might be something you 
perceive differently because you

400
00:19:12,100 --> 00:19:14,900
have to remember that 
responsiveness is a subjective 

401
00:19:15,200 --> 00:19:17,500
perception at the end of the 
day, even though we're trying to

402
00:19:17,508 --> 00:19:22,000
Define it, mechanically it is 
subjective, right, right? 

403
00:19:22,000 --> 00:19:24,500
That there's a lot that goes 
into this and that's why we say 

404
00:19:24,500 --> 00:19:26,000
an art, and a science. 
Yeah. 

405
00:19:26,000 --> 00:19:29,700
Because you have things that you
can quantify and in My lab, it 

406
00:19:29,700 --> 00:19:32,900
looks great and then you put it 
on a real person and then that's

407
00:19:32,900 --> 00:19:35,500
ultimately the real test. 
You know, is how is this doing 

408
00:19:35,500 --> 00:19:38,300
in the field? 
How are people like in this shoe

409
00:19:38,400 --> 00:19:42,300
and just because a certain shoe 
may not work for you? 

410
00:19:42,300 --> 00:19:44,700
Specifically like you said 
earlier, it may work for someone

411
00:19:44,700 --> 00:19:46,900
else and so you kind of look at 
the mass as you can see like 

412
00:19:46,900 --> 00:19:51,700
okay how is this doing overall? 
But yeah I look at 

413
00:19:51,700 --> 00:19:54,000
responsiveness like as an 
experience and that could also 

414
00:19:54,000 --> 00:19:55,500
very. 
Yes, it's good. 

415
00:19:55,500 --> 00:19:58,100
I like the like when we're 
talking about responsiveness, 

416
00:19:58,100 --> 00:20:01,200
you might not want it. 
To be quote unquote, more 

417
00:20:01,200 --> 00:20:04,700
responsive, I think, of looking 
at likes, let's say a track 

418
00:20:04,700 --> 00:20:08,000
race. 
And I'm looking at, let's say 

419
00:20:08,000 --> 00:20:11,900
the Nike Victory 3, versus the 
Nike dragonfly. 

420
00:20:12,000 --> 00:20:15,100
So, yeah. 
For those of those that Dino 

421
00:20:15,100 --> 00:20:16,800
tracks bikes, you'll know what 
I'm talking about. 

422
00:20:16,800 --> 00:20:19,300
If you don't know track spikes, 
when you look at it. 

423
00:20:19,400 --> 00:20:22,600
So, the victory 3 has that 
airbag in the forefoot, a much 

424
00:20:22,600 --> 00:20:25,200
sharper. 
Spike plate, a little bit less 

425
00:20:25,200 --> 00:20:28,900
Zoo, Max. 
I think I'm pretty sure and just

426
00:20:28,900 --> 00:20:30,600
a much. 
Much more aggressive profile and

427
00:20:30,600 --> 00:20:32,700
a carbon plate. 
And when you look at the 

428
00:20:32,708 --> 00:20:36,800
dragonfly little bit, less 
dramatic design, it's kind of a 

429
00:20:36,800 --> 00:20:38,400
more traditional kind of Spike 
plate. 

430
00:20:38,400 --> 00:20:42,700
Pebax bike plate pebax plate 
that runs through the heel. 

431
00:20:42,700 --> 00:20:45,900
So P, Ducks, not we're talking 
plastic, we're not talking 

432
00:20:45,900 --> 00:20:50,500
carbon, you know, do next foam 
minimal upper, they both have 

433
00:20:50,500 --> 00:20:53,600
pretty minimal a, but the 
experience you get from the to 

434
00:20:53,600 --> 00:20:56,600
one of them is like, I don't 
know if my calves can hang for 

435
00:20:56,600 --> 00:21:00,200
longer than like, 1,200 meters 
in the Thing versus like 

436
00:21:00,200 --> 00:21:02,400
dragonfly. 
I feel like I can take 5K pretty

437
00:21:02,400 --> 00:21:05,800
comfortably, but that might not 
be the same for someone else. 

438
00:21:05,800 --> 00:21:07,100
Depending on the mechanics. 
Like, simple. 

439
00:21:07,100 --> 00:21:10,700
My really like that stiff up 
front on your forefoot type 

440
00:21:10,700 --> 00:21:14,200
profile and I don't know if it's
just me getting older but I 

441
00:21:15,300 --> 00:21:17,600
can't I can't do that as much 
anymore. 

442
00:21:17,600 --> 00:21:20,400
Man. 
I was looking track 10 km 

443
00:21:20,400 --> 00:21:22,600
looking at the Avanti of all 
these much more forgiving than 

444
00:21:22,600 --> 00:21:26,100
the dragonfly. 
When you look at the profile, I 

445
00:21:26,100 --> 00:21:28,500
can tell you from what I'm 
seeing initially with collect 

446
00:21:28,500 --> 00:21:30,400
data Inform us on my 
dissertation. 

447
00:21:30,400 --> 00:21:32,600
For those that don't know, is on
Masters Runners and trying to 

448
00:21:32,608 --> 00:21:34,000
figure out what's happening as 
we get older. 

449
00:21:34,000 --> 00:21:35,900
And one of the things that I'm 
kind of seeing consistently as 

450
00:21:35,900 --> 00:21:40,100
we lose gasps Frank like, oh 
yeah, that would explain it for 

451
00:21:40,100 --> 00:21:42,100
those interested one of the 
challenges. 

452
00:21:42,100 --> 00:21:43,500
So I'm in my pilot study right 
now. 

453
00:21:43,500 --> 00:21:46,300
I'm just getting like, whoever 
whether you're, you know, not 

454
00:21:46,300 --> 00:21:48,800
any specific pathology, but the 
full study is looking at, hey, 

455
00:21:48,800 --> 00:21:52,300
those who have Achilles and calf
issues, in those who don't one 

456
00:21:52,300 --> 00:21:54,600
of the challenges I'm running 
into and I'm asking. 

457
00:21:54,600 --> 00:21:58,800
So, my subjects is pretty, and 
I'm because I'm looking at 50 to

458
00:21:58,800 --> 00:22:01,000
70. 
Five-year-old Runners, every 

459
00:22:01,000 --> 00:22:02,700
single one that's coming and 
going. 

460
00:22:02,700 --> 00:22:05,200
Yeah, I've had some calf easier 
to kill his problems in the past

461
00:22:05,200 --> 00:22:07,700
and like, great, I don't know. 
I'm gonna fight anybody. 

462
00:22:07,700 --> 00:22:10,300
That doesn't have this. 
So yeah, it, it's one of the 

463
00:22:10,308 --> 00:22:11,600
things that happens is we get 
older. 

464
00:22:11,600 --> 00:22:14,700
But what I'm hearing, you 
transition to is, when do you 

465
00:22:14,700 --> 00:22:16,600
want this? 
And when you don't, and what we 

466
00:22:16,608 --> 00:22:19,300
don't want, people think, oh, I 
want the most responsive shoe 

467
00:22:19,300 --> 00:22:21,100
all the time, right? 
It's a tool. 

468
00:22:21,100 --> 00:22:22,500
It's something you might want 
some time. 

469
00:22:22,500 --> 00:22:25,200
Might want you might you might 
not and you actually get a great

470
00:22:25,200 --> 00:22:26,200
example. 
So I'm going to put you on the 

471
00:22:26,200 --> 00:22:31,700
spot and go between the zoom 
Victory and the dragonfly, which

472
00:22:31,700 --> 00:22:34,500
one do you find more responsive 
and I'm going to clarify that? 

473
00:22:34,500 --> 00:22:38,000
That's not necessarily a good 
thing for everything, but which 

474
00:22:38,000 --> 00:22:41,100
one do you find more responsive 
of those tracks bikes? 

475
00:22:41,400 --> 00:22:43,000
Depends on the event, we're 
looking at. 

476
00:22:43,000 --> 00:22:45,500
But I probably think I'm just 
going to say, all right, I'm 

477
00:22:45,500 --> 00:22:48,000
going to go there overall 
overall before we go there. 

478
00:22:48,500 --> 00:22:51,000
I mean, the that Victory is 
fast. 

479
00:22:51,300 --> 00:22:52,000
It's got it. 
Okay. 

480
00:22:52,200 --> 00:22:56,000
So what what I'm hearing is you 
got the carbon plate, you got to

481
00:22:56,000 --> 00:22:58,200
way more aggressive set up 
carbon plates to get the plates 

482
00:22:58,200 --> 00:23:00,900
is not everything. 
What I'm hearing is way more 

483
00:23:00,900 --> 00:23:02,700
aggressive. 
Way more responsive from the 

484
00:23:02,700 --> 00:23:04,400
victory, but you're hesitating 
going. 

485
00:23:04,400 --> 00:23:09,900
That's not what I would use. 
So when I came thing is 400 800 

486
00:23:09,900 --> 00:23:14,200
at the longest 1500, you know, I
couldn't even think of doing a 

487
00:23:14,200 --> 00:23:17,900
5k got it. 
So just because something is way

488
00:23:17,900 --> 00:23:20,600
more responsive doesn't 
necessarily mean, that's what 

489
00:23:20,600 --> 00:23:22,900
you want, because shoes are 
tools and you got to have the 

490
00:23:22,900 --> 00:23:25,800
right tool for the job. 
So why you said it earlier? 

491
00:23:25,800 --> 00:23:28,700
But you're going to choose the 
dragonfly, which is a phenomenal

492
00:23:28,700 --> 00:23:31,000
Spike. 
Like but it seems to be less 

493
00:23:31,000 --> 00:23:33,100
responsive compared to this 
other Spike. 

494
00:23:33,100 --> 00:23:37,200
Why would you choose the less 
responsive of the to, for what 

495
00:23:37,200 --> 00:23:40,300
you're doing? 
Yeah, I just think the profile 

496
00:23:40,300 --> 00:23:43,500
is a little bit more forgiving. 
I think, at the paces, I'm 

497
00:23:43,500 --> 00:23:47,900
running a 5k is fast, but it's 
still a controllable Pace. 

498
00:23:48,000 --> 00:23:50,400
You know, you should be able to 
dictate your body a little bit 

499
00:23:50,400 --> 00:23:54,700
more, whereas like let's say an 
800, you're going out hard, 

500
00:23:54,700 --> 00:23:56,100
you're you're going to finish 
hard. 

501
00:23:56,200 --> 00:24:00,900
It's over and I mean On how fast
your running less than two 

502
00:24:00,900 --> 00:24:04,600
minutes, you know, like it's a 
quick race. 

503
00:24:04,600 --> 00:24:09,900
There's not really that much 
room for changing of pace or 

504
00:24:09,900 --> 00:24:11,800
getting in Rhythm. 
Like you're kind of just going 

505
00:24:11,800 --> 00:24:15,100
with what the race gives you. 
The 1500 gets a little bit more 

506
00:24:15,100 --> 00:24:16,900
of that but it's still fast from
the gun. 

507
00:24:16,900 --> 00:24:19,500
You're still running, you know, 
I mean, depending on what your 

508
00:24:19,500 --> 00:24:24,800
times are going for, but you're 
running fast but 5K, you notice,

509
00:24:25,100 --> 00:24:29,600
there's a pretty massive shift 
in tactics and how How you run a

510
00:24:29,608 --> 00:24:32,900
5k. 
And a lot of it is, is 

511
00:24:32,900 --> 00:24:36,700
controlling yourself, you know, 
being disciplined, being strong,

512
00:24:36,700 --> 00:24:38,700
when it gets hard, I mean, 
that's in every race. 

513
00:24:38,700 --> 00:24:42,600
But like, you notice people - 
split five k's way more than 

514
00:24:42,600 --> 00:24:45,500
you'll notice people's - split 
815 hundreds. 

515
00:24:45,500 --> 00:24:49,100
Yeah. 
So like there's a way of 

516
00:24:49,100 --> 00:24:50,800
running. 
It doesn't always have to be 

517
00:24:50,800 --> 00:24:53,000
negative split like there's 
plenty of great ways of running 

518
00:24:53,000 --> 00:24:56,800
5Ks but the point is that you 
can control your body a little 

519
00:24:56,800 --> 00:24:58,800
bit more, you're a little bit 
more in control of what you're 

520
00:24:58,800 --> 00:25:00,900
doing. 
You know, like you kind of have 

521
00:25:00,900 --> 00:25:05,700
a say each lap and you can kind 
of check in and I think as I get

522
00:25:05,700 --> 00:25:09,000
a little bit more tired or even 
just the pace in general, I'm 

523
00:25:09,000 --> 00:25:11,700
not quite as aggressively 
striking either. 

524
00:25:12,200 --> 00:25:16,500
So I think the the way the 
profile of that spike is it just

525
00:25:16,500 --> 00:25:21,200
flows smoother at that pace for 
me and the same thing goes for 

526
00:25:21,200 --> 00:25:24,600
the Adidas Avanti if I was doing
a track 10K tomorrow that's 

527
00:25:24,600 --> 00:25:26,900
probably I would choose that 
over the vapor fly. 

528
00:25:26,900 --> 00:25:30,100
I mean I don't reply dragonfly 
Buy for myself. 

529
00:25:30,800 --> 00:25:33,300
And so it's the same thing when 
you go to the roads, right? 

530
00:25:33,300 --> 00:25:36,100
Like what you choose for a road 
5K might be different than what 

531
00:25:36,100 --> 00:25:40,300
you choose for a half. 
Marathon versus a marathon and 

532
00:25:40,300 --> 00:25:42,400
it might be the same shoe for 
all of them, and that's great. 

533
00:25:42,400 --> 00:25:45,400
If it is you found a shoe that 
response for you, you know, like

534
00:25:45,400 --> 00:25:47,200
that you you're a responder 
right? 

535
00:25:47,200 --> 00:25:52,200
Like, even heard this term 
before and so there's, there's 

536
00:25:52,200 --> 00:25:54,000
definitely a subjective piece to
it. 

537
00:25:54,000 --> 00:25:56,400
But I think, you know, all the 
companies are doing their best 

538
00:25:56,400 --> 00:25:59,000
to quantify, what they're doing.
They're coming out. 

539
00:25:59,200 --> 00:26:01,900
Pretty good product right now. 
I mean, I can pretty confidently

540
00:26:01,900 --> 00:26:06,100
say that across the board 
they're all responsive poppy 

541
00:26:06,100 --> 00:26:09,300
shoes, you know, and they all 
kind of have their strengths and

542
00:26:09,300 --> 00:26:12,500
weaknesses and different areas 
and depending on the runner they

543
00:26:12,500 --> 00:26:15,600
may respond to a given shoe a 
little bit differently and 

544
00:26:15,600 --> 00:26:19,100
better in one company versus 
another, regardless of what that

545
00:26:19,100 --> 00:26:21,900
logo looks like. 
So what I'm hearing is again, 

546
00:26:21,900 --> 00:26:24,600
so, let's expand this and you 
jumped into this on the road 

547
00:26:24,600 --> 00:26:27,500
because most people are going to
be doing more Road stuff than 

548
00:26:27,500 --> 00:26:29,000
track unless you're still, you 
know. 

549
00:26:29,100 --> 00:26:32,200
No post-collegiate or your 
college or High School athlete. 

550
00:26:32,200 --> 00:26:34,200
Most people are going to be 
doing more Road stuff. 

551
00:26:34,200 --> 00:26:38,400
So, when what I'm hearing is, 
when you say you are were super 

552
00:26:38,400 --> 00:26:41,800
responsive shoe, it's a tool, 
write your mechanics in your 

553
00:26:41,800 --> 00:26:44,700
speed need to match that. 
There's some variation, some 

554
00:26:44,700 --> 00:26:46,900
people get away with that. 
But like a shoe that you're 

555
00:26:46,900 --> 00:26:50,800
going to want for like a mile or
5K on the road, may not be the 

556
00:26:50,800 --> 00:26:52,600
same shoe you want for a 
marathon. 

557
00:26:52,600 --> 00:26:55,000
There are some people write, 
like, good example, there's some

558
00:26:55,000 --> 00:26:57,500
people who love the vapor fly 
and they use it for all 

559
00:26:57,500 --> 00:26:59,000
distances and that's great, 
right? 

560
00:26:59,400 --> 00:27:02,600
But a lot of people had a great 
example to was at the Reebok. 

561
00:27:02,600 --> 00:27:06,600
Float:right energy Pro, that you
knew someone that ran marathons 

562
00:27:06,600 --> 00:27:07,500
in there. 
Oh yeah. 

563
00:27:07,500 --> 00:27:10,200
That's goes like this group 
while 5K. 

564
00:27:10,200 --> 00:27:11,800
Yeah, half marathon. 
Mary. 

565
00:27:11,800 --> 00:27:13,800
Yeah, that was like that. 
Three-point not Reebok. 

566
00:27:13,800 --> 00:27:16,500
We are you with that. 
You want to load is a sweep 

567
00:27:16,500 --> 00:27:18,900
likes. 
Crazy, lightweight shoe, three 

568
00:27:18,900 --> 00:27:20,600
point nine ounces. 
I got to look at that. 

569
00:27:20,600 --> 00:27:22,600
Yeah, but Reebok, come on. 
Where are you guys? 

570
00:27:22,600 --> 00:27:26,400
We did, guys, guys, like you had
something good and just hear it 

571
00:27:26,400 --> 00:27:27,200
coming. 
I'm sure. 

572
00:27:27,200 --> 00:27:29,000
All right I'm sure. 
All right, I will be paid. 

573
00:27:29,100 --> 00:27:31,300
Sorry but the action of some 
cool stuff coming this video. 

574
00:27:32,100 --> 00:27:35,900
So yeah I knew of someone that 
would this super light he back 

575
00:27:35,900 --> 00:27:39,000
super low to the ground 3.9 else
racer which was came out of the 

576
00:27:39,000 --> 00:27:43,100
blue at that time was couple 
years ago, would run a mile and 

577
00:27:43,100 --> 00:27:45,300
race marathons in the same shoe 
and that's great. 

578
00:27:45,400 --> 00:27:48,200
Most people aren't going to do 
that that shoe is going to be 

579
00:27:48,300 --> 00:27:51,400
probably out of bounds for most 
people except maybe doing some 

580
00:27:51,400 --> 00:27:54,600
short tracks such as getting 
used to it, whereas they need 

581
00:27:54,600 --> 00:27:57,200
something with way more 
cushioning way, less aggressive 

582
00:27:57,200 --> 00:27:59,300
for a marathon, some people can 
handle It. 

583
00:27:59,300 --> 00:28:03,100
But most people, when you assume
Progressive Shoe super 

584
00:28:03,100 --> 00:28:06,500
responsive shoe, unless you have
the mechanics in the control to 

585
00:28:06,800 --> 00:28:10,600
handle it is going to be better 
at shorter distances like 5K 1 

586
00:28:10,600 --> 00:28:12,800
mile. 
Whereas when you go up to the 

587
00:28:12,800 --> 00:28:16,000
marathon, you might want 
something totally different. 

588
00:28:16,000 --> 00:28:18,200
That's why when people come to 
us asking, hey, I have this 

589
00:28:18,200 --> 00:28:20,800
super duper shoe. 
You know, I'm curious if this is

590
00:28:20,808 --> 00:28:22,800
going to carry me through a 
marathon like you got a test 

591
00:28:22,800 --> 00:28:25,200
that if you can't handle that 
thing, doing some of your long 

592
00:28:25,200 --> 00:28:27,500
runs, you probably shouldn't use
that on your Marathon. 

593
00:28:27,500 --> 00:28:30,400
You might want to go with A 
lightweight trainer or a little 

594
00:28:30,400 --> 00:28:32,200
less aggressive shoe if you want
to finish. 

595
00:28:32,200 --> 00:28:34,300
Because just because you have 
the most responsive thing, 

596
00:28:34,500 --> 00:28:37,300
doesn't mean your body is going 
to agree with that at Mile 20, 

597
00:28:37,400 --> 00:28:39,200
right? 
You got to be able to control it

598
00:28:39,700 --> 00:28:41,400
and it's the same thing with 
training, right? 

599
00:28:41,400 --> 00:28:43,600
So people are like, hey why 
don't I trained in some of these

600
00:28:43,600 --> 00:28:47,000
shoes all the time? 
You may not want that balance 

601
00:28:47,000 --> 00:28:50,600
and aggressiveness when you're 
trying to recover and we talked 

602
00:28:50,600 --> 00:28:53,000
about this in the previous 
episode where we're getting some

603
00:28:53,000 --> 00:28:55,200
of these super trainers that are
coming out and they're great, 

604
00:28:55,200 --> 00:28:57,400
they're super fun. 
They seem to make us a little 

605
00:28:57,400 --> 00:29:01,500
less or but if you're One that 
can't control yourself on easy 

606
00:29:01,500 --> 00:29:04,300
days because you need to make 
sure your body, like, recovers 

607
00:29:04,300 --> 00:29:06,300
on an easy day. 
That's the whole point. 

608
00:29:06,600 --> 00:29:08,900
If you can't control that and 
you start picking up pace, could

609
00:29:08,900 --> 00:29:11,900
it feels good. 
You start ripping out like way 

610
00:29:11,900 --> 00:29:13,300
too fast and easy, Iran than, 
yeah. 

611
00:29:13,300 --> 00:29:14,900
You don't need a responsive 
shoe. 

612
00:29:14,900 --> 00:29:17,700
You need something that feels 
good. 

613
00:29:18,100 --> 00:29:20,800
Cushions you or whatever you 
whether you want Kushner, not 

614
00:29:20,800 --> 00:29:24,200
just helps you get through the 
mileage and recover so that's 

615
00:29:24,200 --> 00:29:25,500
when you're not going to want 
responsive Sue. 

616
00:29:25,500 --> 00:29:28,300
So super responsive. 
Yeah, aggressive when you're 

617
00:29:28,300 --> 00:29:29,600
running super. 
Fast. 

618
00:29:29,600 --> 00:29:32,800
But when you're doing your daily
miles or running easy, you're 

619
00:29:32,800 --> 00:29:35,100
not going to want something 
super responsive because super 

620
00:29:35,100 --> 00:29:36,400
responsive means, more 
aggressive. 

621
00:29:36,400 --> 00:29:40,400
If you can't control it and 
can't handle how the shoe is 

622
00:29:40,400 --> 00:29:42,400
responding to you. 
During those places, you 

623
00:29:42,400 --> 00:29:45,600
shouldn't be looking at that. 
So just because responsive 

624
00:29:46,200 --> 00:29:48,600
doesn't mean it should be on 
your feet every day. 

625
00:29:48,700 --> 00:29:50,500
Some people can handle it, some 
people don't. 

626
00:29:50,800 --> 00:29:55,500
So that the next question goes 
to who would want response. 

627
00:29:55,500 --> 00:29:59,400
I was super responsive shoe and 
who would not want to Of she 

628
00:29:59,400 --> 00:30:01,000
obviously is going to depend, 
what I'm going to throw that in 

629
00:30:01,000 --> 00:30:02,700
your court and see. 
What do you think on that 

630
00:30:02,700 --> 00:30:04,500
question? 
Yeah, I mean responsiveness in 

631
00:30:04,500 --> 00:30:07,000
some ways does kind of fall in 
line with performance. 

632
00:30:07,000 --> 00:30:10,300
I think when you're looking to 
perform, you want to shoe that 

633
00:30:10,300 --> 00:30:12,800
you respond. 
Well to, and that doesn't always

634
00:30:12,800 --> 00:30:15,500
mean a super shoe. 
I know someone that's run a very

635
00:30:15,500 --> 00:30:18,700
fast marathon in. 
What did they run it in? 

636
00:30:18,700 --> 00:30:20,700
It was, I think it was the 
Bondi. 

637
00:30:22,300 --> 00:30:25,200
Okay, with the time I've seen 
this guy, rip some crazy runs in

638
00:30:25,200 --> 00:30:28,300
the bond. 
Well, you have time for the race

639
00:30:28,300 --> 00:30:29,400
again, a bomb. 
I don't know. 

640
00:30:29,400 --> 00:30:32,200
It was like under 220. 
I'm pretty sure my gosh, it was 

641
00:30:32,200 --> 00:30:37,000
like it was like, oh my gosh. 
Yeah, that's impressive. 

642
00:30:37,400 --> 00:30:40,100
Yeah, I've seen I've seen some 
impressive runs in the banda 

643
00:30:40,200 --> 00:30:42,000
proud. 
I keep joking, it's Bondi world 

644
00:30:42,000 --> 00:30:46,200
record, but that's the kind of 
person that like, just that, 

645
00:30:46,200 --> 00:30:48,600
like, that's some somebody. 
Yeah, somebody all. 

646
00:30:48,600 --> 00:30:51,200
Let's runs gonna rip him and be 
like, oh, how fast would this 

647
00:30:51,200 --> 00:30:52,800
person be? 
I assumed it was a him. 

648
00:30:52,800 --> 00:30:55,900
I'm sorry. 
I want to know this, you know, 

649
00:30:55,900 --> 00:30:58,100
this person would be so much 
faster if they were this super 

650
00:30:58,100 --> 00:31:00,500
shoot. 
You don't know that, right? 

651
00:31:00,500 --> 00:31:03,500
That just might be what Jack for
their mechanics. 

652
00:31:03,500 --> 00:31:07,100
Oh yeah, I remember one time I 
can't do this, man, we're 

653
00:31:07,100 --> 00:31:09,400
running, he's like, yeah. 
No, I ran my PR and trainers. 

654
00:31:10,300 --> 00:31:12,600
I was like, wait, what? 
Like, you didn't read like this 

655
00:31:12,600 --> 00:31:14,700
is at a time when everybody and 
their mother was wearing Vapor 

656
00:31:14,700 --> 00:31:16,700
Flies, you know, right, I guess 
we're still kind of in that 

657
00:31:16,700 --> 00:31:19,700
time, we caught her in the face 
till but like, Hey, we're 

658
00:31:19,700 --> 00:31:25,700
talking 2017 2018. 
You know, like all power to you,

659
00:31:25,700 --> 00:31:27,300
right? 
What, again, that's a great 

660
00:31:27,300 --> 00:31:29,800
example and this is not everyone
but There's going to be a good 

661
00:31:29,800 --> 00:31:33,400
number of people who hey a 
marathon a trainer is going to 

662
00:31:33,400 --> 00:31:34,500
work. 
Just fine. 

663
00:31:34,700 --> 00:31:38,500
And you know don't judge people 
it's it what works for people's 

664
00:31:38,500 --> 00:31:39,800
going to be very, very 
different. 

665
00:31:39,800 --> 00:31:45,100
So you the end of the day shoes 
or tools, you need something 

666
00:31:45,100 --> 00:31:46,900
that's going to get you through 
the Finish Line. 

667
00:31:46,900 --> 00:31:49,700
What get you might get you to 
the Finish Line in a mile or 5K 

668
00:31:49,700 --> 00:31:53,300
may not be the same thing as a 
marathon, right? 

669
00:31:53,300 --> 00:31:55,200
Because that's it just depends 
on your mechanic. 

670
00:31:55,200 --> 00:31:59,200
So somebody if you like super 
aggressive shoes, if you That 

671
00:31:59,200 --> 00:32:00,600
feeling you got. 
The can you can handle 

672
00:32:00,600 --> 00:32:01,700
controlling that following 
mileage. 

673
00:32:01,700 --> 00:32:02,800
Yeah. 
Then you might want to 

674
00:32:02,800 --> 00:32:07,300
responsive shoe but I think when
it comes to newer Runners 

675
00:32:07,500 --> 00:32:12,500
especially or those who just 
don't respond well to Super 

676
00:32:12,500 --> 00:32:16,700
aggressive bouncy, super Dwight 
shoes like that then you're not 

677
00:32:16,700 --> 00:32:19,100
going to want that and I want to
go back to what I what I said 

678
00:32:19,100 --> 00:32:20,900
earlier because each person's 
performance is going to be is 

679
00:32:20,908 --> 00:32:23,100
going to depend. 
That's why we encourage you 

680
00:32:23,700 --> 00:32:26,200
don't drink the Kool-Aid. 
Yes, we get excited about this. 

681
00:32:26,200 --> 00:32:28,100
Just like anybody else but you 
got to find what works for you 

682
00:32:28,500 --> 00:32:30,900
but Newer Runners. 
I'm going to really encourage to

683
00:32:30,900 --> 00:32:33,600
stay away from these really 
aggressive shoes. 

684
00:32:33,600 --> 00:32:36,500
You are barely learning how to 
run and the more responsive and 

685
00:32:36,500 --> 00:32:38,800
aggressive issue. 
Is the more you got to be able 

686
00:32:38,800 --> 00:32:41,900
to control that if you don't and
you barely can control your own 

687
00:32:41,900 --> 00:32:45,000
mechanics, you really should not
be using this kind of shoe. 

688
00:32:45,000 --> 00:32:49,600
You should be using a, a more 
gentle less responsive shoe that

689
00:32:49,600 --> 00:32:52,400
feels comfortable and gets you 
through your mileage, right? 

690
00:32:52,400 --> 00:32:55,800
Because like we said, 
responsiveness are definite, 

691
00:32:55,800 --> 00:32:58,100
David's definition, he gets 
credit for this is how the 

692
00:32:58,100 --> 00:32:59,700
reshoe. 
Under load. 

693
00:32:59,900 --> 00:33:02,300
If you have something that 
bounces back too much, you can 

694
00:33:02,300 --> 00:33:04,300
control up, that's not good, 
right? 

695
00:33:04,300 --> 00:33:06,700
Because then you might not 
finish your run and so that's 

696
00:33:06,700 --> 00:33:08,700
kind of the goal. 
So you want to know, you know, 

697
00:33:08,700 --> 00:33:10,900
for a marathon are you paid 200 
something bucks or Marathon you 

698
00:33:10,908 --> 00:33:14,400
want to finish, right? 
So you got to pick that tool 

699
00:33:14,900 --> 00:33:17,900
wisely, and there's a lot of 
subjective stuff to this, so 

700
00:33:17,900 --> 00:33:20,200
don't freak out. 
If your buddy running buddies 

701
00:33:20,200 --> 00:33:22,900
like, yeah, I bought XU and it 
was the most responsive thing. 

702
00:33:22,900 --> 00:33:25,300
I love. 
It's my favorite thing, might 

703
00:33:25,300 --> 00:33:27,400
not work for you. 
You might go run a 219 at Al 

704
00:33:27,400 --> 00:33:29,800
Bundy II, don't think. 
I will be running. 

705
00:33:29,800 --> 00:33:32,400
It's, you know, anything in the 
bottle that I can't even run to 

706
00:33:32,400 --> 00:33:35,200
19 in anything. 
I don't think with rockets on my

707
00:33:35,200 --> 00:33:36,500
legs attached. 
What able to run that? 

708
00:33:36,500 --> 00:33:40,700
So more power to it, but it was 
funny cause you brought up the 

709
00:33:40,700 --> 00:33:43,100
thing about the mile, 20 versus 
another Mile. 

710
00:33:43,100 --> 00:33:45,600
And I had that exact 
conversation a couple weeks ago 

711
00:33:45,600 --> 00:33:50,100
with the new shoe that we were 
trying and one of my friends 

712
00:33:50,100 --> 00:33:51,400
turning is how do you like 
those? 

713
00:33:51,700 --> 00:33:53,800
And I was like, well, I like my 
my late. 

714
00:33:55,500 --> 00:33:57,200
We'll see if I like it at Mile 
20. 

715
00:33:57,500 --> 00:33:59,500
You don't know. 
They'll turn him back right now,

716
00:33:59,500 --> 00:34:01,600
you know, right. 
We're gonna find out what's 

717
00:34:01,600 --> 00:34:03,300
right? 
And that's one of the things 

718
00:34:03,300 --> 00:34:05,600
that Michael Tony that's good. 
That's one of the things. 

719
00:34:05,600 --> 00:34:08,800
Again, I we say this all the 
time that, you know, just 

720
00:34:08,800 --> 00:34:11,000
because it's super bouncy 
responsive, doesn't mean your 

721
00:34:11,000 --> 00:34:13,400
body is going to like that at 
the later stages of some of 

722
00:34:13,400 --> 00:34:15,800
these long races. 
You do not know that. 

723
00:34:16,300 --> 00:34:19,600
So you got to go find out and 
that's going to be a very 

724
00:34:19,600 --> 00:34:21,500
different experience. 
So, I know we're kind of moving 

725
00:34:21,500 --> 00:34:24,300
on from defining responsiveness,
but all I hope what people take 

726
00:34:24,300 --> 00:34:28,699
away from this. 
Is that the more you don't 

727
00:34:28,699 --> 00:34:31,699
necessarily want the most 
responsive shoe for everything 

728
00:34:31,800 --> 00:34:35,300
that has a time and place you 
got to figure out if this that 

729
00:34:35,900 --> 00:34:40,100
term or that concept is matching
what you're looking for at a 

730
00:34:40,100 --> 00:34:42,500
given Pace. 
What do you think? 

731
00:34:43,000 --> 00:34:46,800
Yeah, I like driving a Formula 
One car on, you know, you're 

732
00:34:46,800 --> 00:34:50,300
downtown local Road. 
Probably it's not that it's not 

733
00:34:50,300 --> 00:34:54,800
ideal but like there's a time 
and place for these types of 

734
00:34:54,800 --> 00:34:58,500
things. 
Yeah, and and there there's a 

735
00:34:58,508 --> 00:35:03,600
person for each shoe, you know, 
and like I was one of those guys

736
00:35:03,600 --> 00:35:07,100
Vapor fly, didn't really work 
for me, you know, and next 

737
00:35:07,100 --> 00:35:10,100
percent to still kind of 
doesn't, you know? 

738
00:35:10,300 --> 00:35:13,000
It doesn't, it doesn't like the 
Run well on it, but I don't 

739
00:35:13,000 --> 00:35:15,100
like, I don't like my experience
in it. 

740
00:35:15,100 --> 00:35:17,800
Like, I, that's kind of like, 
I'm running fast, that's because

741
00:35:17,800 --> 00:35:20,400
your heart will always will 
always be taken by the Alpha Phi

742
00:35:20,400 --> 00:35:21,500
1. 
You had that photo again. 

743
00:35:21,500 --> 00:35:23,500
Step earlier we like, hey, good 
track spike. 

744
00:35:23,500 --> 00:35:25,000
No, but Alpha flight. 
Yeah, we're going to just 

745
00:35:25,000 --> 00:35:26,900
kidding. 
Yeah, but with the other fly 

746
00:35:26,900 --> 00:35:29,100
there, like I feel it though. 
I remember we're talking about 

747
00:35:29,100 --> 00:35:30,600
like that. 
Yeah, that's where I like. 

748
00:35:30,600 --> 00:35:33,000
Yeah. 
Feel like I'm doing something. 

749
00:35:33,000 --> 00:35:34,800
Like, I'm getting propelled like
this shoe. 

750
00:35:34,800 --> 00:35:37,800
I'm responding to this shoe. 
I just don't feel that in the 

751
00:35:37,800 --> 00:35:40,900
vapor fly for myself. 
Yeah and other people are going 

752
00:35:40,900 --> 00:35:44,300
to feel that. 
I personally because of for my 

753
00:35:44,300 --> 00:35:48,000
mechanics the instability of the
vapor fly doesn't work for me 

754
00:35:48,000 --> 00:35:51,400
like I can't get that, you know 
it doesn't respond my load. 

755
00:35:51,400 --> 00:35:53,700
Instead my foot is going all 
over the place right mechanics 

756
00:35:53,700 --> 00:35:57,300
so that's why Why this term is 
going to be very different for 

757
00:35:57,300 --> 00:36:00,300
each person we can have 
scientific things. 

758
00:36:00,300 --> 00:36:02,200
Like, what's the foam 
resiliency? 

759
00:36:02,200 --> 00:36:05,200
Or what's the shoe? 
Like economy that's been given? 

760
00:36:05,200 --> 00:36:07,500
If you're testing a large number
of subjects but what that's 

761
00:36:07,500 --> 00:36:11,200
going to mean to each person? 
I know everyone. 

762
00:36:11,200 --> 00:36:14,200
This is what students hate is we
say it depends on the time but 

763
00:36:14,200 --> 00:36:16,900
it really does, right? 
It's and again it also depends 

764
00:36:16,900 --> 00:36:18,700
on who you are and what you're 
looking for. 

765
00:36:18,900 --> 00:36:23,600
I like the car analogy. 
By the way, like for me, how do 

766
00:36:23,600 --> 00:36:26,400
I say this nicely? 
I'm Decent driver. 

767
00:36:26,900 --> 00:36:31,500
I'm not the best driver. 
So I really shouldn't be allowed

768
00:36:31,500 --> 00:36:35,300
to drive a McLaren or something 
like that or a Lamborghini. 

769
00:36:35,300 --> 00:36:38,100
Because on a side street, I'm 
probably going to run that into 

770
00:36:38,100 --> 00:36:40,000
a pole because I'll be losing 
10. 

771
00:36:40,000 --> 00:36:47,200
So you don't like I need a small
tank like a complex, a big guy. 

772
00:36:47,300 --> 00:36:49,700
Yeah. 
Like a Honda Civic or like, you 

773
00:36:49,700 --> 00:36:53,500
know, small a compact SUV, kind 
of car that can take a little 

774
00:36:53,500 --> 00:36:55,100
beating. 
I can get some miles on it. 

775
00:36:55,300 --> 00:36:57,800
I can handle him. 
Be scraping some curbs, right? 

776
00:36:58,100 --> 00:37:00,000
You can't do that in a 
Lamborghini, right? 

777
00:37:00,000 --> 00:37:03,900
Do you do that like that, that 
dent cause you know, who knows? 

778
00:37:03,900 --> 00:37:05,100
How much? 
And that's a great analogy. 

779
00:37:05,100 --> 00:37:07,000
Like, let's say you're in the LA
area. 

780
00:37:07,000 --> 00:37:09,000
I mean, I'm yeah. 
Santa Barbara, we're close 

781
00:37:09,000 --> 00:37:10,000
enough. 
Oh, gosh. 

782
00:37:10,000 --> 00:37:14,600
That's a of tomorrow at 6 a.m. 
you had a call and you have to 

783
00:37:14,600 --> 00:37:17,700
go to San Francisco, and you can
choose any car, you want to go 

784
00:37:17,700 --> 00:37:20,500
to San Francisco and you gotta 
go up to 5. 

785
00:37:21,300 --> 00:37:22,700
Are you going to go? 
Grab the Ferrari? 

786
00:37:22,700 --> 00:37:26,500
Are you going to go and more go 
for Comfort? 

787
00:37:26,600 --> 00:37:27,800
I'm going to go for Comfort, 
right? 

788
00:37:27,800 --> 00:37:29,600
Kick my butt. 
That's going to drive. 

789
00:37:29,800 --> 00:37:34,200
I've been driven, I've got to 
drive a Lamborghini before, and 

790
00:37:34,200 --> 00:37:36,600
it was a very cool Xterra 
fighting experience. 

791
00:37:37,000 --> 00:37:39,000
But those seats were not 
comfortable. 

792
00:37:39,000 --> 00:37:41,700
Like I get, it's like there. 
She can go fast, you don't die. 

793
00:37:41,700 --> 00:37:43,400
But I'm like, I wouldn't want. 
This is right? 

794
00:37:43,400 --> 00:37:46,800
Like, mix my like that's the 
best analogy, right? 

795
00:37:46,800 --> 00:37:50,700
Like if we're going six hours 
and you want to choose Comfort 

796
00:37:50,700 --> 00:37:53,800
over, Quote, unquote for 
fragments, you know, because 

797
00:37:53,800 --> 00:37:57,300
that's what responds to you, 
then that makes sense that's 

798
00:37:57,400 --> 00:38:00,800
versus if I want to go to a 
racetrack and I want to go as 

799
00:38:00,800 --> 00:38:02,500
fast as possible. 
Yeah, that's probably what I'm 

800
00:38:02,508 --> 00:38:05,900
going to choose, right? 
So, it's again, going to vary on

801
00:38:05,900 --> 00:38:07,700
who you are, what? 
And you know what? 

802
00:38:07,700 --> 00:38:11,200
There's probably someone who can
take a McLaren or a Lamborghini 

803
00:38:11,200 --> 00:38:16,300
and peel it from LA to San 
Francisco, and has the consider 

804
00:38:16,300 --> 00:38:20,000
the driving ability that I don't
know if my students when I'm 

805
00:38:20,000 --> 00:38:22,900
driving what Driving to campus, 
like what? 

806
00:38:22,900 --> 00:38:25,100
That swerving Honda Fit. 
Oh, that's dr. 

807
00:38:25,100 --> 00:38:27,000
Klein okay, never mind. 
I'm just kidding. 

808
00:38:27,400 --> 00:38:32,000
Yeah, me, when I drive an l.a., 
any time ever the city? 

809
00:38:32,500 --> 00:38:34,700
Yeah, that's a whole other 
podcast. 

810
00:38:34,700 --> 00:38:37,500
I'm driving in Las Vegas. 
Put getting used to it. 

811
00:38:37,700 --> 00:38:40,700
So, back pulling us back on 
topic. 

812
00:38:40,900 --> 00:38:45,200
So we're defining responsiveness
as how a reshoe response to 

813
00:38:45,200 --> 00:38:49,200
load. 
How a shoe is going to respond 

814
00:38:49,200 --> 00:38:50,900
to you and how you're going to 
respond to this. 

815
00:38:51,200 --> 00:38:55,500
And when you white month want 
that is going to vary quite a 

816
00:38:55,508 --> 00:38:57,600
bit. 
So what we hope that people take

817
00:38:57,600 --> 00:39:00,400
away is that there's different 
ways that shoes can do this in 

818
00:39:00,400 --> 00:39:02,800
two ways. 
You can do this, you still have 

819
00:39:02,800 --> 00:39:05,800
to decide, is this tool 
appropriate for you and what 

820
00:39:05,800 --> 00:39:09,200
you're going to use it for. 
So a shoe you might use for Mi 

821
00:39:09,200 --> 00:39:11,100
may not be the same shoes that 
you're going to use for a 

822
00:39:11,108 --> 00:39:14,100
marathon or an ultra marathon. 
And that's why we always say 

823
00:39:14,100 --> 00:39:16,300
shoes are tools, right? 
So you got to figure out what 

824
00:39:16,300 --> 00:39:19,600
works for you, whether that's 
the best thing, we hope that 

825
00:39:19,600 --> 00:39:22,300
clarifies this, Is there 
anything else you would add to 

826
00:39:22,308 --> 00:39:24,600
that? 
No, I think, I think we got, 

827
00:39:24,600 --> 00:39:26,900
right, and if there's anything 
we missed, feel free to leave it

828
00:39:26,900 --> 00:39:29,300
in the comments and yet, leave 
it in comments to get back to 

829
00:39:29,300 --> 00:39:31,000
it. 
Yeah, subjective again. 

830
00:39:31,100 --> 00:39:32,800
What do you think it means, 
right? 

831
00:39:32,800 --> 00:39:35,100
How would you define it? 
There's a lot of pieces to it. 

832
00:39:36,000 --> 00:39:38,000
We always try to simplify 
something down, but sometimes 

833
00:39:38,000 --> 00:39:41,400
it's not possible. 
So that's what we think of 

834
00:39:41,400 --> 00:39:43,800
responsiveness. 
We always appreciate, appreciate

835
00:39:43,800 --> 00:39:46,800

00:40:27,000 --> 00:40:39,600
You can handle it.
