(STILL) DESIGNED TO HELP KEEP RUNNERS RUNNING. The Nike React Infinity 2 has soft and supportive cushioning, built to help keep you on the run. A refreshed Flyknit upper uses Flywire technology for support and breathability where you need it. Higher foam provides soft responsiveness and long-lasting comfort, plus a wider forefoot helps lessen the chance of stress-related injuries. It's still one of our most tested shoes, designed to help you feel the potential when your foot hits the pavement. Ventilated Where Needed An advanced Flyknit upper provides breathability where you need it most. It's strong and durable, helping to keep your foot secure with every mile. Flywire technology offers extra support and stability through the midfoot. Smooth Ride Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. Shaped like a rocker, the foam provides support for the 3 phases of a runner's stride. It offers flexibility when your foot rises off the ground, a smooth ride when your foot is moving forwards and cushioning at ground contact. Cushioned Feel, Higher Stacks Less material between the insole and midsole means you're closer to the foam. This helps create a more responsive experience. The foam itself has a higher height, providing a plush feel.
