The Victory 2 is tested and validated by the best middle-distance runners sprinting the planet. It sports every speed component you need to smash records in style, from a carbon fiber Flyplate to Air Zoom unit to a lightweight, responsive ZoomX midsole. Atomknit on the upper and midfoot containment cables combine with a supportive base that delivers improved stability and control of the shoe, especially around the turns. Zoom, Zoom - The forefoot Air Zoom unit has two chambers to give you propulsive feeling and stability from takeoff to the tape. Stable for Straightaways - The supportive base creates a wider flat area on the bottom compared to the original Victory. We switched the traction to a four-spike design and elevated the big-toe side platform to help the spikes feel more stable on the straightaways and especially around turns. Built for Speed - The full-length carbon fiber Flyplate is tuned to match the base of the support system. Its shape and stiffness give a propulsive feel to help keep you on your toes and minimize deceleration. Lightweight Upper - Atomknit, an updated version of Flyknit, has a lightweight, contoured fit and enhanced breathability. It works with a new knit structure and midfoot containment cables to give you an ultralightweight upper. Plus, a gold chain and charm across the laces detach for a customized look. What's New? - New plate material is lighter and more responsive than the previous version. Improved durability of the outer traction plate
