B15 Design of a Lower Shell of Ski Boots Based on features of Frame of a Skier

Abstract

Ski boots are important for assisting progress in ski turning technique as an interface between a skier and a ski. In the alpine races, suitability of ski boots is important for quick and accurate lean motion of a skier in ski turns. This study is aimed at building the new design of ski boots that can improve the results of alpine ski races. In this paper, the new design of lower shells of ski boots that can keep center position and adjust the application point of reaction vector on the bottom of ski boots, was examined. Finally, the effectiveness of the new design of lower shells has been verified in field tests by Japanese alpine ski racers.
