Built in conjunction with the Air Zoom Alphafly but with a target for track athletes competing in the 800 to 5,000 meters, the Air Zoom Victory is redesigned from top to bottom. A brand new AtomKnit upper gives one of the lightest-weight upper Nike has ever put on a spike with unparalleled breathability, and it sits atop a sole of a Zoom Air unit in the forefoot with ZoomX foam in the heel giving the incredible responsiveness and stability you expect out of Nike's top racing shoe. And did we mention there was a carbon fiber plate sandwiched into the midsole as well? This might not lead to world records like it has for some of Nike's athletes, but it will be a darn fun ride.Unisex sizing: both Mens and Womens sizes listed.
