Nike InfinityRN 4

Road running shoe for women. With the React Infinity 4, you'll be ready to go right out of the box and leave all your worries behind. It's built with soft, responsive React foam and updated with our most snug-fitting Flyknit. So you can take off anytime, anywhere without worrying about wear and tear. It's the kind of shoe that gives you the priceless feeling of running longer, faster and farther than ever before thanks to high foam stacks and an intuitive design that supports every step. Smooth and Stable The rounded outsole provides a more natural feel and efficiency while you run. So you waste less energy while running. It provides flexibility when the foot comes off the ground, a smooth running feel when the foot moves forward, and cushioning during ground contact. Optimal Cushioning Nike React technology uses durable, lightweight foam for a soft, responsive ride. Stacked cushioning is located directly underfoot so you're closer to the foam and enjoy a truly responsive feel. Support and Breathability Flyknit in the upper provides breathability to keep your foot feeling secure without suffocating. A water-resistant lining in the toe area provides protection in inclement weather. So you can keep going and not be slowed down by the elements. The Flyknit tongue is adjustable and soft to keep your ankle and heel from getting too irritated on longer runs. An integrated Flyknit fit band provides an elastic, secure fit. Foam shoe collar provides a soft, supportive feel. Reinforced rubber on the outsole provides traction and durability.
