Reebok Nano X3 - woMen?s Vector Navy / Semi Proud Pink / Vector Blue The Reebok Nano X3 goes further than ever to merge a world class women?s training shoe with a top-flight running shoe. This latest design introduces a new Lift and Run Chassis system, with a unique dome-shaped heel piece that compresses under load when lifting to create a stable platform, then softens when you push off to run. Once you?re on the move, Reebok?s Floatride Energy Foam ensures lightweight cushioning for maximum comfort, while a durable rubber outsole and lug pattern deliver reliable multi-surface traction. The Nano?s classic Flexweave woven textile upper is back, as well, providing targeted support and resilient stretch. Built for everything from squats to box jumps, burpees to wind sprints, the Women?s Nano X3 and its new line-up of colorways remain at the forefront of true cross-training versatility.
