These attractive socks are joined together stitch by stitch resulting in no ridges, and administering the ultimate in comfort. No wrinkles equals no abrasions or blisters. A strong elastic at the top of a sock is not sufficient to keep a sock in place. These socks have additional Lycra support sections throughout the calf, so you won’t find them cutting off circulation or falling down in to your boot. High-friction areas contain two sections of polyamide, a technical fiber that provides life-long treatment against odor, fungus and bacteria, and extraordinary wicking capabilities result in enhanced comfort. The Boot socks, made of 75% Antimicrobial Treated Schoeller Polycolon and 25% Polyamide/Lycra, are longer to provide additional warmth to lower leg. Built to last. M (5.5-9.5), 
L (10-12.5), XL (13-15).
