Push past your doubters in one of the most versatile training shoes on the market. The Nike Metcon DSX Flyknit training shoe was created to handle distance running, strength training, and cross-training, which is where the DSX name comes from. 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. This trainer was born ready to handle your toughest workouts.
