The Nike Air Zoom SuperRep Men's Fitness Shoes support your foot and improve cushioning for forefoot-stressing movements that you can't avoid during circuit training, high-intensity interval training and other fast-paced classes. The innovative design flexibly cushions and improves stability. A lightweight cover layer hugs your foot and holds it in place, even when you're pushing it hard. Two Zoom Air units in the forefoot provide flexible cushioning. A foam midsole increases comfort under the entire foot, and Cushlon foam in the heel helps absorb shock during intense exercise.
