Abstract: Device for sliding on snow, especially a carving ski, having a base running face, which extends over a front, a central and a rear zone and which is waisted in the longitudinal direction, wherein in the front and/or in the rear zone of the base running face, the latter is overlaid by at least one additional running-face segment which, together with a portion, especially the central portion, of the base running face defines a second running face having a second waist with a substantially larger radius of curvature.

Abstract: A short ski is a board-like member having middle and front sections with the rear and front sections turned upwardly. The ski sole is plastic and the maximum ski length is between 63 to 80 cm and preferably between 70 to 75 cm. The middle section has a minimum width. The front section has the maximum width and the rear section is between the minimum width (B) of the middle section and the maximum width of the front section. The ratio of the minimum width with the middle section to the length is between 0.12 and 0.23, preferably between 0.13 and 0.16. The lateral delimitation of the middle section has the width reduction by two radii (R1, R2) such that radius (R2) of the lateral delimitation adjacent the rear section (10) is about 480 to 500 cm, of the lateral delimitation adjacent the front section is about 250 to 270 cm. The middle section is upwardly curved at a maximum distance from the flat ground (17) of 1.5 mm to 6.0 mm. The rear section in plan view is semicircular, with a radius (R5) of about 5.
