For the days when the rains hiss and the winds howl but your running needs must be met, no matter how bleak it looks out the window, the Infinity 4 GTX is your go-to. It's layered with water-proof GORE-TEX throughout, highlighted by a warm heathered collar, to keep your feet dry when the conditions are dripping and dropping. Combine those thermal-like attributes with our Nike ReactX foam, which gives you 13% more energy return compared to Nike React foam. What's more, Nike ReactX reduces the carbon footprint of the midsole by at least 43% compared to Nike React foam, so it helps support the planet too. You'll be seeking out puddles and piles as you rack up the miles.
