3-D printed bio shoes that repair themselves.
From crazy cushioning to ludicrously lightweight fabrics, the science of running shoes has evolved well beyond pockets of air.

Reacting to pressure, impact and movement, the shoes would puff to provide extra cushion when needed and even repair themselves overnight.
