Keep pushing your runs to the limit. The Nike ZoomX Invincible Run Flyknit 2 keeps you going with the same supersoft feel that lets you feel the potential when your foot hits the pavement. It's one of our most tested shoes, still designed for you to stay on the track and away from the sidelines. Secure, Cushioned, Comfortable 3 Flyknit components were placed in different areas of the shoe. At the tongue, seamless engineering has created soft padding and an adjustable fit. The vamp is soft, with a highly secure fit. And finally, the heel is built with a clip for containment and cushioning. The result is an upper that keeps your foot feeling comfortable and stable while you pound the pavement. Higher, Softer, Wider Higher foam heights provide an even softer feel. A wide, exaggerated shape at the forefoot offers a more stable ride. More Bounce with Every Ounce 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 forward and cushioning at ground contact. This info also helped guide the design and look of the shoe's sidewalls. More Details Not intended for use as Personal Protective Equipment (PPE) DH5425-005.
