The original Superfeet Premium Insoles shoe insert's design provides maximum comfort and shock absorption. These insoles, sold in wide and regular, are recommended for running, hiking, alpine and industrial activities, and are ideal for medium- to high-arched feet. As with all Superfeet Insoles, they feature a firm stabilizer cap for optimal underfoot support. The deep heel cup cradles the heel's fat pad to improve its natural shock absorption. Finally, the Encapsulating Stabilizer System (ESS) provides comfort and stability for a variety of different activities. These shoes aren't just for high-performance athletes, or for those facing podiatric illness and medical conditions; these insoles can help anyone with feet to experience a more comfortable stride.
