The curve which fulfills required criteria could be an envelope of each circle of the curvature of the given curve which is performed by a skier in a given moment during steering through a turn, an arc of a circle, brachistochrone, cycloid or any combination of sine curves. The width of the ski according to the invention at its narrowest point, i.e. in the middle section (1), lies within the range of 63 +/- 5 mm, at its widest front section (A-A) the width thereof lies within the range of 110 +/- 10 mm and at its widest rear section (B-B) the width thereof lies within the range of 100 +/- 10 m. <IMAGE>
