Prepare to show your wild side with the Nike React Infinity Run Flyknit 2, the shoe that keeps you up and running. Refreshed with a cheetah print in the Swoosh and collar, it uses Flywire technology combined with Flyknit to give you support and breathability where you need it. The high foam heights provide soft responsiveness and long-lasting comfort. It's still one of our most-tested shoes, designed to help you feel the potential when your foot hits the pavement. 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. 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. 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, giving you a plush feel.
