The BioSkin Calf Skin is a specially designed calf sleeve constructed of Ultima material (strong, thin, moisture-wicking, neoprene-free material) which provides full length compression for both the calf and leg region. It provides excellent pain relief associated with shin splints, strains, and contusions. BioSkin Calf Sleeve products are made from a three layer fabric that is compressive, hypoallergenic, and thin for easy wear and washing. The BioSkin Calf Skin calf skin provides a firm, uniform fit and reduces pain with running activities.
