<p>A cross-country ski (1) with a forward section (2), a central section (3) and a rear section (4) and comprising an arch such that the central section (3) of the ski lies higher than the forward and rear sections when the ski is not under load. The ski (1) comprises at the location of the arch a spring- loaded arrangement (6) that extends in the longitudinal direction of the ski, and where an empty compartment (8) is present between the upper surface of the ski and the lower surface of the spring-loaded arrangement (6) closest to a binding (7) on the ski, whereby the spring-loaded arrangement (6) is designed to collapse at a certain load applied from above such that when placed under load by the skier' s foot (9) the spring-loaded arrangement (6) collapses and the central section (3) of the ski is pressed down such that its lower surface is pressed against a surface (10) under the ski (1), through the ski (1) being divided in its longitudinal direction at the location of the arch such that it comprises a rigid central part (12) and a pliable lower part (11), where the pliable lower part (11) is arranged such that it separates from the rigid central part (12) when the spring- loaded arrangement (6) collapses, in order to be pressed down against the surface (10) under the ski.</p> |
