Nike ZoomX foam is responsive and lightweight, giving you bounce with every step. 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. Flyknit technology uses high-strength fibres to create a lightweight upper with targeted areas of support, stretch and breathability. It provides security and comfort. Waffle-inspired tread on the outsole provides traction. Nike mens Pegasus Turbo Road Running
