Sizes: Unisex 5-15M (see size chart) WOMEN ORDER ONE SIZE DOWN SOLE Softec Response Custom Footbeds feature an orthopedic base layer that molds to your unique foot. This custom support gently lifts your arch into its optimal position, allowing your foot to function as it was meant. When the arch is properly supported and the body is aligned, performance is enhanced in the following area SOLE Footbeds mold to fit your unique foot perfectly. Generic insoles and flat footwear simply cannot offer the same level of arch support, control and comfort that SOLE products can. The benefits of our orthopedic shape are personalized for your unique foot. The arch height adjusts to your required level, but does not flatten out. The forefoot takes the shape of the balls of your feet and toes, and the aligning heel cup supports your unique heel shape. This creates a continuous contact point across the soles of your feet, leaving no area unsupported. It all adds up to a superior fit, and unrivaled support and comfort. Softec Cushioning is the best cushioning material for providing your feet with maximum comfort. Softec has the best compression set rating. This means that it instantly springs back to its original shape better than any other material tested. Softec has a shock absorption rating that is equal to the industry standard cushioning material, Poron. Softec is stronger and has a higher stretch resistance than Poron. Softec stretches more without snapping when force is applied, which means Softec is strong and flexible.Moldable, orthopedic base layer.American Podiatric Medical Association Accepted..
