This helps to alleviate shin splints as well as prevent calf cramping. The risk of injuries is also reduced, as the compression in the leg sleeves help to provide muscle stabilization. Non-Itch Merino Wool: Made of Zensah's innovative FastWool material (innovative merino wool), the compression leg sleeves provide a natural insulation to athletes while enjoying their favorite activities outdoors. The merino wool leg sleeves are non-itch and fit comfortably against the skin. Whether using the sleeves during a long run or jog, runners and all athletes are able to comfortably wear the leg sleeves for hours at a time. Anti-Odor and Moisture Wicking: The compression leg sleeves are anti-odor, meaning they help to prevent the buildup of bacteria and stink within the compression leg sleeves. They are also moisture wicking, transporting moisture away from the skin through the fabric to the air where it evaporates. Graduated Compression for Faster Muscle Recovery: The graduated compression in each pair of FastWool Compression Leg Sleeves features the most amount of compression in the ankle and the least in the calf area. This helps to improve circulation and blood flow, leading to a decreased muscle recovery time after a hard workout or run. Sold as a pair: The FastWool Compresson Leg Sleeves are sold as a pair  i.e. two sleeves per purchase.
