<p>Snow ski The side portions (4) of the ski have, beginning from the immediate vicinity of the longitudinal running edges (3) and at least for the major part of the length of the ski, respective surfaces converging towards the upper surface (1) and angled with respect to the bottom running surface (2) between 30 and 50.degree.. The slant of the side portions reduces, in use, the lateral friction facilitating the changes of direction in the case of fresh and deep snow, and assures a more effective grip of the running edges in the case of hard and frozen snow.
