Unisex Superfeet Run Support Medium Arch

Medium arch signature Superfeet shape adds stability and comfort to your running shoes, reducing stress on feet, ankles, knees, and back. Improves efficiency, reduces fatigue, and supports every step. Responsive EVOLyte® carbon fiber cap and a thin layer of Aerospring™ Rebound comfort foam for a versatile fit combine to create smooth and efficient energy transfer throughout your gait, from foot strike to toe-off. Made to replace the removable liner in moderate to tight-fitting running and walking shoes.  Medium arch orthotic support helps stabilize the foot while running, reducing stress on feet, ankles, knees, and back. Heel cup positions and cradles the heel to optimize natural shock absorption and minimize fatigue. Stabilizer cap with proprietary EVOLyte® carbon fiber and polymer blend responds to compression, springing back to its original shape for responsive, weight-defying support. Moisturewick™ top cover helps reduce odors and keeps feet fresh. H.I.T. (Heel Impact Technology) Pod disperses impact at heel strike for an easier ride. A thin layer of Aerospring™ Rebound comfort foam delivers ultimate comfort in every step and a versatile fit. Superfeet insoles keep their shape, delivering reliable support and comfort for up to 12 months or 500 miles, whichever comes first.
