A ski or snowboard having improved the transmission of forces from a binding mounting area to the respective edge of a ski or snowboard is disclosed. Such a ski or snowboard comprises a gliding surface with the associated edges as well as a lower support comprising a number of support layers over which a core with its associated lateral flanks is built. Over the core, a support is arranged in a uniform and relief-like manner that is constructed as a uniform whole from the shaped flat material, for example from laminate or in principle also from shaped sheet metal, or a plate or laminate or a similar flat semi-finished product of metallic or non-metallic material.

The ski or snowboard according to claim 1, wherein a spacing or period (t) of the upward or downward arcs gradually varies in a set running along the number of indentations of the support in the front section of the ski or snowboard so that, when viewed in a direction away from the middle section of the ski or snowboard, the spacing or period (t) gradually decreases from an initial value to a final value. 12. The ski or snowboard according to claim 1, wherein a spacing or period (t) of the upward or downward arcs gradually varies in a set running along the number of indentations of the support in the rear section of the ski or snowboard so that, when viewed in a direction away from the middle section of the ski or snowboard, the spacing or period (t) gradually decreases from an initial value to a final value. 13. The ski or snowboard according to claim 1, wherein a spacing or period (t) of the upward or downward arcs or sine-shaped arcs gradually varies in sets running along the number of indentations of the support in the front section and rear section of the ski or snowboard so that, when viewed in a direction away from the middle section of the ski or snowboard, the spacing or period (t) gradually decreases from an initial value to a final value. 14. The ski or snowboard according to claim 1, wherein a spacing or period (t) of the upward or downward arcs or sine-shaped arcs gradually varies in a set running along the number of indentations of the support in the front section of the ski or snowboard so that, when viewed in a direction away from the middle section of the ski or snowboard, the spacing or period (t) gradually increases from an initial value to a final value. 15. The ski or snowboard according to claim 1, wherein a spacing or period (t) of the upward or downward arcs or sine-shaped arcs gradually varies in a set running along the number of indentations of the support in the rear section of the ski or snowboard so that, when viewed in a direction away from the middle section of the ski or snowboard, the spacing or period (t) gradually increases from an initial value to a final value. 16.
