A running surface (4) extends between lower side edges (12) and is transversely concave in the front and central regions of the ski (2) and, at the rear of the ski (2), gradually changes to a transverse shape which facilitates sideways sliding. The lower side edges (12) bite into the snow. This biting action and the shape of the running surface (4) permit a skier to move faster and to turn by merely tilting the ski (2) up on one of its lower side edges (12).
