Nike developed this with world-record holding amputee triathlete Sarah Reinertsen and Össur. The sole has a stacked design and uses a stretch rubber leash over a rubber waffle outsole. Nike used ‘regrind‘ materials salvaged from reused shoes, a polyurethane foam midsole that was topped by a thermal plastic, which was made from recycled air bags.

Plastic tabs lock the sole in place. Reinertsen tested the prototypes and worked with the design team to develop this incredible high-performance running solution.

Seriously though, I wonder when, if not already, amputee runners will be able to run faster than able-bodied ones.

The spring-loaded PoweriZers amplify the pressure of your jumps enabling you to perform death-defying feats of athleticism.

Now I don’t need to tell you this, but bouncing ten feet in the air on something that combines a pogo stick and stilts isn’t for everyone. PoweriZer’s makers assume that you’re a) physically fit; b) have impeccable balance, and c) aren’t afraid to break a few bones while you learn how to use them.
