Superfeet COPPER DMP® Footbed is the perfect support for low to medium arched feet, yet accommodates all arch types. It naturally molds to your unique foot shape through daily wear, giving you a personalized fit without having to heat the insole in an oven. As the DMP® foam adapts to the shape of your foot, the insole's biomechanical integrity remains intact for support and stabilization. Agion antimicrobial technology provides long-lasting protection against bacteria to keep your feet from stinking.
