SORBOAIR insoles are the ultimate analgesic for dog-tired, beat up feet. SorboAir superbly balances a lightweight, air-infused composition of Sorbothane with heavy-duty cushioning upon cushioning. The result is three soft layers of soft comfortable shock-absorption and cushioning for all day comfort. These high-performance insoles are ideal for court sports such as basketball and tennis, as well as for running, walking and post-workout relief. SorboAir gives athletes that "extra full-court" cushioning and protection.
