Nearly 9,000 miles away from South Africa, here in Fort Smith, Arkansas, we found a man who knew Oscar Pistorius
00:00:11
before he became an international icon. My name is Francois Vanderwat and I helped create the Blade
00:00:19
Runner. We originally started just drawing on a piece of paper what a blade maybe should look like. And I mean,
00:00:26
there's no science behind it. It was kind of a trial and error. It's like shoes. You got to make that custom fit
00:00:33
for you. So, how does this work? So, here we have what we call a regular walking prosthetic. So, when we work
00:00:40
with an athlete, this part is going to be taken away. This is what we uh call the cheetah foot. So, it's very similar
00:00:47
to what Oscar used. And this specific model was actually inspired by Oscar. This is made of carbon fiber and he
00:00:56
sprints with the blade. Yes. So, this connection point here is where we can now start making adjustments. This is
00:01:03
spike plate. So, uh Nike actually developed this specifically for this foot. You're always thinking, what can I
00:01:09
do better? What can I align better? Can I make it faster? Can I help improve his
00:01:15
performance? But is it an an advantage? No, it's not an advantage because this will only gives back what is put into
00:01:22
it. So if the athlete doesn't apply the force or the load to it, it's not going to return that. I think it's more of
00:01:29
optimizing to complement what he naturally has. It feels like, wow, this is pretty unreal to see you go so fast
00:01:37
around the track.
