Nike Air Zoom Victory 2 Track & Field Mid-Distance Spikes 。Nike Victory 2 Track & Field Distance Spikes 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, 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 propulsion and stability from takeoff to the tape. Stable for Straightaways Focused on helping keep you stable, the supportive base creates a wider flat area compared to the original Victory on the bottom of the plate. We removed two spikes seen on the original in favor of a four-spike design. And we elevated the big-toe side platform to help the spikes feel more stable on the straightaways and especially around the 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. The new plate material is lighter and more responsive than the previous version. 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.
