Mogul skiing Mogul skiing Mogul skiing is a freestyle skiing competition consisting of one timed run of free skiing on a steep, heavily moguled course, stressing technical turns, aerial maneuvers and speed. Internationally, the sport is contested at the FIS Freestyle World Ski Championships, and at the Winter Olympic Games. Moguls are a series of bumps on a piste formed when skiers push snow into mounds as they do sharp turns. This tends to happen naturally as skiers use the slope but they can also be constructed artificially. Once formed, a naturally occurring mogul tends to grow as skiers follow similar paths
Ski wax snow. Glide wax is selected to minimize sliding friction for both alpine and cross-country skiing. Grip wax (also called "kick wax") provides on-snow traction for cross-country skiers, as they stride forward using classic technique. Modern plastic materials (e.g. high-modulus polyethylene and Teflon), used on ski bases, have excellent gliding properties on snow, which in many circumstances diminish the added value of a glide wax. Likewise, uni-directional textures (e.g. fish scale or micro-scale hairs) underfoot on cross-country skis can offer a practical substitute for grip wax for those skiers, using the classic technique.
