The rain is pounding, the wind is howling, but your need to run is stronger than what's happening outside: the Infinity 4 GTX is made for these days. Dressed in a waterproof GORE-TEX coating, it features a warm heathered collar to keep your feet dry when the weather conditions are less than optimal. Added to these thermal benefits is our Nike ReactX foam. 13% more energy return compared to React foam... What more could you ask for? To take care of our planet, Nike ReactX reduces the carbon footprint of the midsole by at least 43% compared to Nike React foam. And you're going to want to jump in all the puddles that are on your route.
