SKI



The skis are made from a complex combination of components like glass fiber, Titanium, Kevlar or composite materials, many skis contain a wooden core too. The user is attached by bindings which in turn hold the ski boots. Beginning in the early 2000's, many ski manufaturers began designing their skis and bindings together, creating an 'integrated binding system.' These systems serve two purposes. First, they often use a railroad track style design, to allow the toe and heel pieces to slide, which in turn allows the ski to flex deeply, without a flat-spot underfoot, caused by the presence of a binding. Second, it forces the consumer to purchase both skis and bindings from the same manufacturer, increasing profits.


Snow skis glide on snow because downward pressure, as well as heat from surface friction, melts the snow directly under the ski. This creates a very thin layer of water directly under the ski upon which the ski glides. This is why if there is freezing rain that freezes to the bottom of the ski perhaps when carrying the ski, the ski, when set down on the snow, won't glide until the ice wears off or is knocked off. Ski wax is used to decrease drag by increasing the water repellency properties of the base.
