A Flyknit training shoe that offers you all the flexibility you will need in the gym is finally here. The Nike Metcon DSX Flyknit training shoe gives you what you need to handle your distance running, strength training, and CrossFit® workouts. Talk about versatile! This shoe's flyknit upper is flexible and breathable, but also supportive enough to help you stay locked-in and give you the natural movement you need with your foot. The Metcon DSX Flyknit also offers a heel counter to give you rear foot stability, a drop-in midsole to provide comfort and stability for your heel during lifts and cushioning for your foot-strike during runs, and sticky rubber on the bottom of the shoe in your forefoot for added traction. Get ready to take on your toughest workouts with this trainer on-foot! Flyknit upper creates a barely-there feel that promotes natural movement. Drop-in midsole is firmer in the heel for stability, yet softer and more flexible in the forefoot to provide comfort. Firm rubber in the heel provides durability and a stable feel for high-intensity intervals.
