The Infinity 4 GTX is the perfect choice for those days when the rain is pouring and the wind is blowing hard, no matter how gloomy it looks outside the window, but you still want to run. It features a waterproof GORE-TEX layer throughout and a warm, heathered collar to keep your feet dry when temperatures drop and it starts to rain. Combine those thermal attributes with our Nike ReactX Foam, which delivers 13% more energy return compared to Nike React Foam (what more could you ask for?). Nike ReactX Foam reduces the midsole’s carbon footprint by at least 43% compared to Nike React Foam to help the planet too. You’ll be looking for puddles and piles as you rack up the miles.
