Bauerfeind Sports Run and Walk Unisex Compression Socks (1 Pair) IMPROVE LEGS' STAMINA: Sports Run and Walk Compression Socks improve the legs stamina during endurance sports and support faster recovery times. GENTLE COMPRESSION: The blood supply to the muscles is improved, resulting in increased endurance. The gentle compression stabilizes the calf and reduces muscle vibrations, which helps to counteract premature fatigue. COMFORT AND EASY CARE: The sports socks feel lightweight and comfortable on the skin and have a temperature and moisture-regulating effect. The sole and instep sections are lightly padded, and a cut-out in the sensitive area of the Achilles tendon prevents pressure and friction. FIT AND SIZING: To determine size, measure the circumference at the widest part of the calf. Shoe size will determine the appropriate length. Refer to the sizing chart in the product images for a size/length to associate with this measurement. 100% SATISFACTION GUARANTEED: With proper use and care, our products are designed to last.
