ZoomX Invincible Run FK2 - Black/Summit White
The Nike Zoom X Invincible Run Flyknit 2 offers a precise balance of comfort and supportive structure to your daily training. Carrying through the same responsive ZoomX foam cushioning as its predecessor, now in a higher stack height to provide an even softer feel. Shaped like a rocker, the foam supports all three phases of a runner's stride, providing flexibility when your foot rises off the ground, a smooth ride when your foot moves forward, and cushioning at ground contact.
