Leg warmer

Leg warmers are coverings for the lower legs, similar to socks but thicker and generally footless. They were originally used as dancewear by ballet and other classic dancers in order to keep the leg muscles warm and to prevent cramping or other muscle injuries. No scientific data has been yet collected to substantiate the claim that leg warmers prevent injury.

Traditionally knitted from pure sheep wool, modern variants are more typically made of cotton, synthetic fibers, or both. Some are made of other materials, such as chenille.

Leg warmers can vary in length, and in width, due to the material's stretchiness. They are commonly worn between the ankle to just below the knee, though many dancers prefer it to extend to cover the lower parts of the thigh. Some cover the entire foot - these 'warmers' usually have a pad that grips the floor so the dancer does not slip - however this has been known to cause career-ending injury . Some leg warmers are particularly short and made of thinner material; these are also known as 'ankle warmers'.
