15 years of excellence in the gym and the Reebok Nano isn't ready to slow down. The Reebok Nano X5 is built to be the most comfortable version yet. Flexweave remains for the upper delivering soft comfort and abrasion resistance. Gym versatility kicks up a notch with the dual-density midsole firmer in the heel for a stable lifting base and soft foam in the forefoot for responsiveness. The Metasplit outsole enhances flexibility underfoot, perfect for brief runs.
