These calf compression sleeves by PRO Compression are the perfect combination of advanced materials and design, providing the ultimate in comfort and performance. The moisture control properties keep you dry, even during your most extreme activities. With the non-slip design, these compression sleeves will stay in place during all of your favorite endeavors. Graduated compression technology helps improve blood flow, resulting in less fatigue and a faster, more efficient recovery. In addition to improving vascular performance, calf compression sleeves provide support to critical muscles and tendons, helping reduce inflammation and soreness. Unlike traditional athletic socks, compression sleeves use stronger elastics to create significant pressure. Compression sleeves are tightest around the ankles, and gradually become less constrictive towards the knees. By compressing the surface veins, arteries and muscles, the circulating blood is forced through narrower circulatory channels. As a result, the arterial pressure is increased, which causes more blood to return to the heart and less blood to pool in the feet.
