This is what obsessively measured with Subject A and Subject B when they spent 2 weeks in the lab with me: 

1. Flight Time - Which is the fraction of your stride spent airborne — both feet off the ground. It’s the moment between toe-off and the next ground contact.

And my goal was to develop a shoe that increased flight time.

Because if I did, then here’s what you’d get out of it:

• Longer flight without added effort extends stride length.

• Reduced braking forces on landing.

• Improved running economy (less wasted energy).

Yeah, you’d run faster for longer.

Then i was also obsessed with…

2. Weight 

Ounces specifically. Because a few ounces added to every step over the course of 10,000 steps is a lot of unneeded weight. Just do the math.

Anyways, so I cracked it. We developed a shoe that’s 30 grams lighter. Yeah, 30 grams.

That’s big when we’re talking about daily training sessions. Hundreds of runs throughout the year.

Just think…

Less mass = less work per step.

Gold.

But that’s just some of it - as we spent more time in the lab we discovered more and more.

That’s it for today but tomorrow I’ll share more of our studies.
