Like one of those barbed-wire tattoos. Except bike chains. And on your ankle. And on a sock. Paneled for a snug, movement-free fit that increases comfort while reducing blisters, the Sock Guy Chains Socks are made of 75% moisture-wicking micro-denier acrylic, 15% nylon, and 10% spandex, and feature a 3-inch cuff. Double-stitched heel and toe for durability. Available in sizes S/M and L/XL. Made in the USA.
