My soft, calf-length socks are my sole mates. They're comfy as can be and made of a cotton, nylon, spandex blend. Machine wash warm, tumble dry medium, and use non-chorine bleach as needed.
Since this is not optional, this one is great to use.
Perfect as a Christmas stocking stuffer, added bonus of being very cute and super comfortable.
Comfortable, fun and functional...what more could you want?
