The Sof Sole Airr Men's Insoles combine an air chamber and gel cushion for maximum comfort during your run. The SKYDEX air chamber in the heel and arch provides support as well as rebound with each step. Gel in the forefoot adds cushioning and shock absorption for additional comfort. With a medium arch height, these insoles are suited for most runners. As an added benefit, a COOLMAX fabric covers the top of the insole to quickly remove sweat and keep your feet cool and dry.
