The Nike Air Zoom SuperRep is designed for circuit training, HIIT, short runs and other fast-paced exercise. Zoom Air cushioning in the forefoot combines with a wide, stable heel to keep you moving and lifting comfortably. Two Zoom Air units in the forefoot are lightweight and responsive for jumping. Cushlon foam at the heel helps absorb impact from high-intensity reps and cushions during lifts. A plate runs the length of your foot for stability as you move through your routine. It distributes pressure over the Zoom Air units to activate responsive cushioning. The flexible slip-on design is covered with mesh for breathability, durability and a supportive feel.
