Reebok Nano X3 Unity

Unisex sizing: M = Men's size, W = Women's size

The Nano X3 training shoes are updated with the all new Lift and Run (L.A.R.) Chassis system. A dome-shaped heel piece compresses under load when lifting to create a stable platform, then softens when you push off to run. It all rides on award-winning Floatride Energy Foam that gives you lightweight cushioning to make that run the easiest part of the workout.
