Skiing is a recreational activity using skis as equipment for traveling over snow. Skis are used in conjunction with boots that connect to the ski with use of a binding.

Skiing can be grouped into two general categories. The older of the two disciplines originated in Scandinavia and uses free-heel bindings that attach at the toes of the skier’s boots but not at the heels. Types of Nordic skiing include cross-country, ski jumping and Telemark. Alpine skiing (more often called “downhill skiing”), originated in the European Alps, and is characterized by fixed-heel bindings that attach at both the toe and the heel of the skier’s boot.
