The cross-country ski according to the invention is characterized by a relatively regular curvature of the lower surface of the ski, i.e., a curvature such that the modules of variation of slope of the lower surface of the ski is less than 9.104 cm-1 when the ski is at rest. Simultaneously, the front zone of the ski has a relatively high rigidity. Likewise, the rear zone can be relatively rigid. Preferably, the lateral surfaces of the ski are hollowed. Such a ski structure is particularly well adapted to obtain a good gripping of the edges, a good sliding on the edges, and a good sliding in direct tracks.
