The Nike MC Trainer 2 allows you to go from circuit training in the weight room to fitness exercises on synthetic turf without losing your rhythm. This multi-tasking shoe combines versatility, stability and durability to keep you focused during your workouts. From barbell squats to sprint sets, it adapts to the rigors of your diverse workout routine while eliminating the need for multiple workout gear. The flat base is wider around the heel to stabilize your foot when working with weights. Reinforced toe box and laces add strength to withstand the rigors of your indoor workouts. The support system wraps the heel and sides of the shoe to ensure a snug fit when you tighten the laces. Soft foam cushions and supports the foot, rising up the sides to stabilize the foot during lateral movements. The rubber outsole grips synthetic surfaces as well as the gym floor. It's thicker under the heel for stability when lifting weights, and thinner in the front for flexibility during sprints and speed drills.
