The Nike Air Zoom SuperRep was designed for high-intensity interval training (HIIT) and other high-intensity workouts. Lifting weights is made possible by the wide, solid heel and the Zoom Air cushioning in the toe area. Lightweight Zoom Air components in the toe region offer responsive comfort during jumping. The heel's cushion foam provides cushioning for weightlifting and shock absorption during high-intensity repetitions. Throughout your whole workout, stability is guaranteed by the full-length sole. The Zoom Air elements are compressed by the sole, which initiates responsive cushioning.
