Nordic skiing encompasses the various types of skiing in which the toe of the ski boot is fixed to the binding in a manner that allows the heel to rise off the ski, unlike alpine skiing, where the boot is attached to the ski from toe to heel. Recreational disciplines include cross-country skiing and Telemark skiing.

Skiing is the use of skis to glide on snow. Variations of purpose include basic transport, a recreational activity, or a competitive winter sport. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski and Snowboard Federation (FIS).
