Abstract
A sports shoe has a sole assembly with cylindrical recesses which grip longitudinally slit generally cylindrical shells of slightly larger initial diameter. The projecting ends of these shells can serve as attachments for gripping elements such as studs, attached thereto for example in the same manner. Alternatively, these projecting ends can be so shaped as to constitute integral gripping elements.
Claims7
A sole assembly for a sports shoe comprising:
- a sole member provided with a plurality of generally cylindrical recesses extending from the ground-contacting surface of the sole member at least part way through its thickness;
- at least one gripping element having a cylindrical recess extending at least part way therewithin;
- respective generally cylindrical shells longitudinally slit throughout their entire lengths and press fit into said gripping element recesses;
- said shells extending from the gripping elements into respective cylindrical recesses in said sole member;
- the diameter of said sole member cylindrical recesses being slightly less than the original diameter of the cylindrical shells whereby the shell outer surfaces are pressed into frictional engagement against the sole member recess inner surfaces;
- the diameter of the gripping element cylindrical recesses being less than the diameter of the sole member cylindrical recesses.

A sole assembly for a sports shoe comprising:
- a sole member provided with a plurality of generally cylindrical recesses extending at least part way through its thickness, from the ground-contacting surface;
- at least one gripping element having a recess extending at least part way therewithin;
- an attachment element engaging each said gripping element recess and comprising a generally cylindrical shell longitudinally slit from end over at least part of its length;
- said shell extending from the gripping element into one of said cylindrical recesses in said sole member;
- the diameter of said cylindrical recess being slightly less than the original diameter of the cylindrical shell whereby the attachment element outer surface is pressed into frictional engagement against said recess inner surface;
- each gripping element being molded from synthetic polymeric material and the attachment element being engaged therein during molding.
