A ****sock is an *item of **clothing worn on the feet. The foot is among the *heaviest **producers of ***sweat in the body, as it is able to produce over 1 US PINT (0.47 l) of PERSPIRATION per day. ****Socks help to ***absorb this ***sweat and draw it to areas where air can EVAPORATE the PERSPIRATION. In cold environments, ****socks ***decrease the risk of FROSTBITE. Its name is ***derived from the **loose-*fitting SLIPPER, called a SOCCUS in Latin, worn by Roman COMIC **actors.
