Flyknit throughout the upper, creating specific zones geared towards optimal breathability, flexibility and containment. Hybrid tongue combines a sock-like feel with the adjustability of a traditional design. Soft padding along the collar provides a cushioned touch point. Flywire technology for support through the midfoot. Shaped like a rocker, the foam provides support for the 3 phases of a runner's stride; offers flexibility when your foot rises off the ground, a smooth ride when your foot is moving forward and cushioning at ground contact. Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. Less material between the insole and midsole means you're closer to the foam giving you a more responsive feel. Higher foam heights provide an even softer feel. Brand new. Original box - NO lid.
