Shoe fastening system

Abstract

The present disclosure relates to a shoe fastening system. The shoe fastening system includes a shoe part, a rail, and an insertable intermediate adapter for compensating a distance between the rail and the shoe part. The shoe part can have a flat underside. The rail can have a surface in the heel area which is raised relative to a ball area. The shoe part can have at least one displaceable mounting plate for screwing in a fastening screw for the intermediate adapter. The intermediate adapter has three through-openings for inserting a fastening screw. The first through-opening is arranged in the center of the intermediate adapter, the second through-opening is arranged on one side of the intermediate adapter and the third through-opening is arranged on the other side of the intermediate adapter.
