Claim:
Ski or snowboard in the form of a board-type gliding device, comprising at least one top belt for imparting strength, at least one bottom belt for imparting strength and at least one core disposed in between, a top layer constituting the top face of the gliding device and a running surface constituting the bottom face of the gliding device, and, by reference to the width of the gliding device, at least one recess is provided in its middle portion extending in its depth direction from the top face of the gliding device in the direction towards the running surface and disposed in its longitudinal direction essentially parallel with the longitudinal direction of the gliding device with a view to causing a cross-sectional weakening and reducing the stiffness of the gliding device transversely to its longitudinal direction, so that a force directed from the ground upwards to an area beside the longitudinal center axis of the running surface directly deforms the cross-sectional shape of the gliding device transversely to its longitudinal direction and leads to a convex deformation of the running surface of the gliding device, being provided with means for influencing the load-dependent variability of the cross-sectional shape of the gliding device transversely to its longitudinal direction, wherein at least one manually adjustable adjusting means is provided which is designed for an individual presetting of setups concerning the cross-sectional and intrinsic elasticity of the gliding device transversely to its longitudinal direction or for individually presetting the limit of the maximum permitted elastic deformation of the transversal cross-section of the gliding device due to the cross-sectional and intrinsic elasticity of the gliding device transversely to its longitudinal direction wherein the adjusting means includes a support means that is of an essentially wedge-shaped design and that is mounted predominantly inside the recess in a way that it can be individually adjusted in the vertical direction towards the running surface with a view to providing mutual support for the longitudinal side walls of the recess so that the recess is spread proportionally to the lowering of the support means into the recess.
