Improve circulation and speed healing with these Mild Graduated Compression Over-The-Calf Socks. Graduated 8-15 mmHg compression combined with infrared technology provides support for muscle stiffness and soreness. Infrared ceramic crystals are permanently infused into the polymer yarn, which harnesses your body's natural heat to improve circulation. Increased blood flow helps speed up healing and drives cellular regeneration, shortening recovery time. Moisture wicking fabric transports wetness away from skin, trapping it in the fabric's outer surface to keep feet comfortable and dry. These compression socks for women and men are designed for maximum comfort, wear and durability, featuring comfort welt top, expanded heel pocket, seamless toe and reinforced heel and toe. Arch band compression lessens sock movement to reduce the possibility of blisters. Infrared ceramic crystals remain effective for the life of the product, won't wash out. FDA listed.
