Bauerfeind Sports Ball Racket Unisex Compression Socks (1 Pair) STABILITY WITH AGILITY: Sports Ball and Racket Compression Socks feature an innovative muscle toning zone to reduce muscle vibrations of the calf and an ankle taping zone for improved body awareness. Both features combine for optimal performance. GENTLE COMPRESSION: The Sports Ball and Racket Compression Socks feature innovative taping and muscle toning zones that provide support for the ankle and calf muscles. The taping zone improves sense of stability, while the muscle-toning zone stimulates the calf muscles. 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.
