See K2 sales and technical rep John Schmoock talk about K2 ski construction at Alpine Accessories ski and snowboard shop.
First there were wood skis, then fiberglass skis, then metal edges, next came shaped skis, then rockered skis! Skis have really changed over the years. But it's the profile of a ski which determines who it's for and where it is designed to go. Whether it's camber to help with rebound, torsional stiffness for edge hold, rocker for turn initiation and versatility, or an increased sweet spot, K2 is a leader in skis.
Almost all skis have some degree of rocker. When you lay a ski on the snow without rocker, the base touches the ground from tip to tail, weighted or unweighted. A ski with rocker would may only contact the ground under the feet. While very few skis have this extreme rocker, most skis will have some variance of rocker. Rocker helps you initiate the turn when you lay the ski on its edge. You'll especially notice it at low to medium speeds and in slush or deep snow. Find out what rocker will do to help your skiing.
K2 has been some of America's best selling skis for over 50 years! Why? Maybe because K2 is located in the state of Washington just west of the mountains where they have an excellent place to design and test skis. K2 has been designing and testing skis in the states since the 1960's and continues to produce some of the best skiing skis around.
