A sock is a knitted or woven type of hosiery garment for enclosing the human foot. Sock is also the term given to the layer of leather or other material covering the insole of a shoe. When only part of the insole is covered, leaving the forepart visible, this is known as a half-sock. The average foot has 250,000 sweat glands, and the average pair gives off about half a pint of perspiration per day. Socks help to absorb this sweat and draw it to areas where air can wick the perspiration away. In cold environments, socks help to retain/remove the moisture given off by one's feet, decreasing the risk of frostbite. There was a shoe worn by Roman comic actors called soccus in Latin. It was a slipper and fitted loosely so it could be taken off quickly
