Small size offers the same benefits of the AIREX Balance Pads but is perfect for training in confined spaces. Innovative AIREX foam is comprised of millions of small air bubbles that invite barefoot training. The yielding foam activates and sensitizes the whole body. Balance pads improve balance, strength, ankle/joint stability, stamina and coordination by adding challenge to an existing workout and aiding in rehabilitation. Textured surface for improved grip. Do not wear shoes while using.
