A sock is an item of clothing worn on the feet and often covering the ankle and some part of the calf. Some type of shoe or boot is typically worn over socks. One of the roles of socks is absorbing perspiration. The foot is among the heaviest producers of sweat in the body. Socks help to absorb this sweat and draw it to areas where air can evaporate the perspiration. In cold environments, socks made from wool insulate the foot and decrease the risk of frostbite. Socks are worn with sport shoes (typically white-coloured socks) and dress shoes (typically dark-coloured socks). In addition to the numerous practical roles played by socks, they are also a fashion item.
