The Nike React Infinity Run Flyknit 2 continues to help reduce injury and keep you running. A refreshed upper uses Flywire technology that combines with Flyknit for 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. Come Together This special-edition colour celebrates unity as athletes worldwide emerge from the year's past events to compete. It's a celebration of sport, humanity and our ability to push through the toughest of challenges. Celebrate the Swoosh The Swoosh celebrates its 50th anniversary by intertwining the past and present. The original Swoosh is outlined over the current version, representing the path Nike has taken from yesterday to today. Ventilated Where Needed An evolved Flyknit upper features zones of breathability where you need it. It's strong and durable, helping to keep your foot secure with every mile. Flywire technology offers extra support and stability through the foot. 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 softer feel.
