A ski and a method of forming a ski. The ski includes a lower element and an upper element, each having the shape of a beam casing. The lower element has an upper surface that has either a longitudinally extending groove or a longitudinally extending projection and the upper element has a lower surface that has a groove or a projection that has a transverse cross-section that is respectively complementary to a transverse cross-section of the groove or to a transverse cross-section of the projection of the lower element, and in which the groove or projection of the lower element is nested in the projection or groove, respectively, of the upper element. Depending upon the nature of the desired response characteristics of the ski, the interior of the upper and lower elements can be selectively filled with specific materials or left empty.
