Hockey socks are ankle-to-thigh garments worn over protective gear by ice hockey players. They are form-fitting, and traditionally made of a cotton or synthetic rib-knit fabric.

Experiments have been made with a lightweight fabric "sock," of material similar to that used in hockey jerseys, and most recently (mid-2000s) with a streamlined lightweight "sock" used by the U.S. Olympic and other international teams. Hockey socks should not be confused with hockey skate socks which are thin, traditional style socks worn over the foot (inside the skate).[1]
