The invention relates to a board-type runner device ( 1), in particular a ski (2) or a snowboard, comprising several layers disposed between a running surface facing (4) and a top layer (6) and a core component (15). At least a bottom face (19) of the core component (15) adjoins a layer (20) that is elastically flexible and rebounds when forces are applied to it. The core component (15), which is mounted on the elastic layer ( 20) so as to be flexible at least in the direction perpendicular to a running surface (3) of the runner device (1), has compression-resistant projections (21) formed on its top face ( 23) or separate compression-resistant spacing elements (22) are supported directly on its top face (23). Fixing screws ( 25) for binding parts or for mounting rails thereof or binding plate(s) are anchored in the projection (21) of the core component (15) only or are additionally also anchored in the core component (15) or the fixing screws (25) are retained in the core component (15) exclusively in a load-bearing arrangement with the spacing element (22) inserted in between.
