The Progress COMPRESS SOX compression socks increase the efficiency of muscle activity and therefore your performance. The firm and compressive material reduces muscle vibration, promotes blood flow and tissue oxygenation and reduces muscle damage during prolonged exercise. In addition, the compression socks help to achieve more effective recovery, reduce leg swelling and muscle pain after sports performance. They have a wide elastic cuff below the knee to ensure a firm fit on the leg. The foot areas are fitted with an elastic band around the instep, which prevents the socks from moving on your feet.
