INNOVATIVE CUSHIONING. LIGHTWEIGHT SUPPORT. Power through each rep with a redesigned shoe that brings support and stability to your every move. It's lighter than previous versions so you can hit your fastest pace during circuit training and HIIT. Plus, Zoom Air cushioning and flexibility underfoot keep you ready for every lunge, step and jump. Lightened Up A slimmed-down design with leaner cushioning and less bulk helps you stay light and fast on your feet. More Stability With your foot closer to the ground and a plate that connects the front and back of the sole, the shoe is more stable whether you're cutting from side to side or moving up and down. Side-to-Side Support The 3 optimises support for lateral moves like side lunges and skier jumps. A big arc acts like a brace and pairs with added reinforcements on the heel and sides to secure your foot. Spring in Your Steps 2 powerful Zoom Air units under the forefoot return your energy to launch you into your next step or jump.
