FIELD: sports. ^ SUBSTANCE: invention relates to winter sports equipment. With this invention a winter sports equipment is to be created, which runners sliding surface is formed so that the sliding film or water film stabilise better. Winter sports equipment with runners having sliding surfaces adjacent to the surface of ice or snow, with profile grooves passing in the direction of motion. On both sides on the edges of the profile grooves (4) on the sliding surface (1, 2), ridges (5) in the form of nodules with a rounded cross section project passing parallel to them. Between the ridges (5) of adjacent profile grooves (4) there are central sliding zones (11) passing in the direction of motion, and the sliding surfaces (1, 2) with profile grooves (4) and their ridges (5) are provided on the blades (3) or on the sliding edges (21), connected to the runners with the possibility of disconnection. ^ EFFECT: improved ability of runners gliding. ^ 13 cl, 4 dwg |
