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. Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. The foam itself has a higher height for a softer feel. 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 forward and cushioning at ground contact. The Swoosh design mashes up classic Nike logos. Less material between the insole and midsole means you're closer to the foam. This helps create a softer, more responsive experience. Increased rubber at the outsole helps deliver traction and durability. Cushioned collar provides soft comfort. A wide shape provides a more stable ride, helping release energy with every step. Loop at the heel for easy on and off.
