FIELD: sports. ^ SUBSTANCE: invention refers to sports goods and may be used in ski structures. Invention facilitates motion of skier forward due to reduced friction of ski against snow by development of air cushion between support platform of ski and ski track using weight of skier and some of their muscular efforts in phase of repulsion by support leg. Ski comprises base, fixator for shoes and support elastic platform-heel pad for foot part of shoes with upper contact surface inclined at sharp angle to ski base. Platform-heel pad is arranged in the form of spring-loaded reservoir made of elastic material, connected by through channels to sliding surface of ski base, besides outlet holes of channels are arranged in central furrow of sliding ski surface, at the same time direction of jets of air pushed out by foot prevents reverse sliding in repulsion phase. ^ EFFECT: accordingly, sliding speed increases with unchanged anthropological and physiological capabilities of sportsman. ^ 1 dwg |
