Whatever your "why" is for working out, the Metcon 9 makes it all worth it. Nike have improved on the 8th with a larger Hyperlift place and added rubber rope wrap. Sworn by some of the greatest athletes in the world, they are intended for lifters, trainers and go-getters, it's still the gold standard that delivers day after day. This version has Nike's FlyEase technology to help make these shoes ready to put on and take off.
