The OS1st CS6 Performance Calf Sleeves provide relief from Achilles tendonitis, shin splints, leg cramps, and much more using support and graduated, medical-grade compression to stabilize the Achilles and support the calf muscle. OS1st's Compression Zone Technology applies varying levels of pressure to six different zones, giving you just the right amount of compression in each area to promote circulation and hasten recovery while keeping you comfortable at rest or during workouts. With a slim profile, the OS1st CS6 Performance Calf Sleeves can also be comfortably worn under clothing. During workouts, moisture-wicking fabric and a shaped-to-fit form-fitting design help keep the sleeves on securely, preventing chafing and making sure they stay in place no matter what you're doing! Each package includes two compression sleeves.
