Patented articulated ankle joint sleeve allows for unrestricted movement while providing mild compression and support to the joint. The over-the-calf design promotes improved circulation during active use as the open-toed foot allows for improved circulation at rest. True medical-grade compression promotes better circulation, which leads to faster recovery through improved removal of lactic acid from the muscles. Quick drying, moisture transfer design for improved comfort. Sold in pairs. Black only. Latex free.
