Telemark – Named after the Telemark region of Norway, this discipline combines elements of Alpine and Nordic skiing. A relatively new competitive sport, Telemark racing is contested at the FIS Telemark World Cup and the FIS Telemark World Championships. Grass skiing – Originally developed as an alpine skiing training method, skiing on grass has become established as a skiing discipline in its own right. It is contested at the FIS Grass Skiing World Cup and the FIS Grass Ski World Championships. Equipment Equipment used in skiing includes: Skis, which may have skins applied or be textured for uphill traction or wax applied for minimizing sliding friction. Twin-tip skis are also designed to move forwards or backwards. Boots and bindings Poles Helmets Ski suits Ski goggles Skiing gloves Ski masks Technique Technique has evolved along with ski technology and ski geometry. Early techniques included the telemark turn, the stem, the stem Christie, snowplough, and parallel turn. New parabolic designs like the Elan SCX have enabled the more modern carve turn. On other surfaces Originally and primarily a winter sport, skiing can also be practiced indoors without snow, outdoors on grass, on dry ski slopes, with ski simulators, or with roller skis. A treadmill-like surface can also be used, to enable skiing while staying in the same place. Sand skiing involves sliding on sand instead of snow, but the skier uses conventional skis, ski poles, bindings and boots for the surface.
