How is this possible, I thought the Adidas boost midsoles literally stored energy in those TPU balls to fire it back into each running stride when the foot left the ground. The Adidas advert had those ball bearings bouncing off the boost foam multiple times to show the energy return compared with other midsoles. Surely that would work better than a carbon plate?!
I guess I was more suckered by the Adidas marketing campaign...
I've tried both. The difference in amazing ! The adidas shoe is soft, but it feels like the return is lost in (no better word for it) misdirection. The Nike shoe is laser focused on forward return. I've only done training runs in them to test, but the Nike shoe is close to 30secs per mile faster.
