That is, it is provided as needed and if necessary removable or replaceable riser or repelling zone 5 is provided.
  • the climbing or kicking zone 5 can also be converted to a further sliding zone by inserting a running surface section, in particular a sliding lining, into the recess 44 with increased slidability.
  • a depth 47 of the recess 44 is dimensioned such that the recess 44 extends into the preferably plate-shaped force distribution element 13. Consequently, a base 48 of the recess 44 is formed or limited by the material of the force distribution element 13.
  • the base 48 of the recess 44 is thus formed by plastic, in particular by a hard plastic.
  • a need-releasable coupling between the support member 46 and the recess 44 is preferably achieved or supported by magnetic action.
  • at least one permanent magnet 49, 49 ', 49 " is arranged in the recess 44, which can be placed in and out of the magnetic interaction or attraction with the backlash hammers 6, in particular with its support element 46.
  • a width 50 of the recess 44 measured transversely to the ski direction, to be slightly smaller than the width 18 of the tread surface 7 in the region of the rising or pushing zone 5, so that a peripheral boundary 51 of the recess 44 on the one hand passes through the tread surface 7 and on the other hand by the preferably plate-like force distribution element 13 is formed.
  • the magnetic force or the mutual magnetic attraction is chosen such that a tool-free separation of the support member 46 and the remindgleithemmers 6 relative to the sliding board body 4 is made possible.
