The Spenco Women's Total Support Original Insole provides semi rigid support and motion control to athletes who over pronate. Its antimicrobial, low friction top cloth fights blisters and odors when you're running and engaging in exercise. This insole is thermowear moldable, meaning it'll shape your foot over time for a custom fit. The semi rigid cradle provides advanced arch support and deep heel cupping, while the 3 POD cushioning absorbs shock with its multi density impact zones. Additionally, you'll find its Metatarsal arch support relieves forefoot pressure, while grooved PU forefoot crash pad offers a cushioned feel under the ball of your foot.
