The Superfeet Performance Insoles deliver heavy-duty shock absorption and support for running, walking, hiking, and more. These high-profile insoles provide a firm bed of support to stabilize the foot and reduce stress on your feet, ankles, and knees. At the base, a rigid stabilizer cap supports the rearfoot and lends structure to the high-density, closed-cell foam layer, ensuring long-lasting cushioning and comfort. Featuring Superfeet's widest and deepest heel cup for maximum natural shock absorption, these durable insoles are finished with an all-natural, organic odor-control coating to eliminate odor-causing bacteria.
