Length of the load platform equals 0.5-0.75 of the length of the skis, and the maximum bulge of the curve of the load platform is situated with a shift to the back end of the snowshoes in the range of 0.25-0.45 of the length of the snowshoes. Guide elements are made in the form of one or several ridges and are located on the entire length of the shoes. On the lower surface of the guide ridges there are several rows of grooves in a circular shape, in which is rigidly fixed villiform at an angle of 30°-45° in relation to the sliding surface directed to the back end of the shoes. Fasteners for the snowshoes are in form of straps, while the support area for binding shoes in the form of a platform. Platform for binding shoes from the side, adjacent to the upper surface of the skis has two grooves, one of which is deep into the thickness of the strap at an angle of 60°-75° in relation to the lateral axis in symmetry to the binding platform and backs up from the front edge of the platform by 0.2-0.4 of its length. Second groove is located mirrored in relation to the first on at a depth double the thickness of the strap.
