  • the clamping parts To displace snow from the openings, the clamping parts on their outer sides on helical grooves. When large forces occur, for example due to downhill impacts, the edges of the grooves may injure the surface of the inside of the openings.
  • the conical or semicircular interventions of the clamping parts in the conical openings can lead to an unwanted, premature release of the ski binding at these forces, since even with forces parallel to or against the direction of travel, this immediately the clamping parts along the conical surface of the openings from the openings can displace.
  • a first aspect of the invention relates to a ski boot having a pin receptacle for a pin or pin, the pin engaging the pin receptacle for connecting the ski boot to a ski for alpine skiing and / or touring.
  • the pin holder is connected to a base plate, which is connected to the ski boot or integrated into the ski boot, respectively the ski boot sole.
  • the base plate may comprise two or more pin receptacles and be permanently attached to the ski boot. Inextricable means that base plate and ski boot can not be separated from each other without destroying each other.
  • the base plate may be arranged in / on the ski boot, in particular in the region of the toes and / or the footpad and / or in the region of the heel of the ski boot. If a ski boot comprises a first base plate in the area of the toes or of the foot and a second base plate in the area of the heel, both base plates are preferably separate base plates which do not touch at any point.
  • the first and second base plates may be connected to each other via a web or skeleton construction or via a center plate.
  • the base plates of a first material for example aluminum
  • the web of a for example, elastically deformable second material.
  • Each of the pin receivers includes a receiving aperture that is adapted to receive a pin.
  • a receiving aperture that is adapted to receive a pin.
