A cross-country ski (300) comprises a slide surface (302) composed of a first material, a top surface (301), a tail (303) and a tip (304). Between the slide surface and the top surface there are a first edge side (306) and a second edge side. The edge sides are composed of a second material. The surface energy of the first material is smaller than the surface energy of the second material. In the invention the first edge side is at least partly covered with a side coating, which side coating is at least partly composed of a first material or material having substantially similar properties than the first material, i.e. the material on the slide surface. This side coating lessens the total friction between the surfaces of the ski and the snow. |
