Nike ZoomX foam provides Nike Running's best energy return to date. The ZoomX Invincible is designed for long runs by incorporating lightweight, responsive ZoomX foam with increased height for a smooth stride. In the forefoot area it has an exaggerated and wide shape which makes it a stable shoe and its rocker shape allows for support in all three phases of the stride: flexibility at toe-off, softness in the midfoot and cushioning on the surface. On the upper, it incorporates Flyknit fabric, a breathable and durable type of fabric. Regarding traction, we will get it thanks to the waffle-like shape of the outsole. Finally, let's not forget the comfort we get in the ankle area which is more padded.
