Abstract: The invention concerns a sports-shoe sole with metal bushes open toward the sole tread and comprising, at their inside walls, fastening elements (for instance inside threads) to mount grippers such as studs, spikes, golf cleats etc., each metal bush being concentrically enclosed at a radial distance from plastic fastening elements.A sports-shoe sole designed in such manner not only is suitable for all gripper types known heretofore but furthermore also for very special, novel grippers for which the fastening members are in the form of a plastic sleeve comprising fastening elements (for instance an outside thread) at their outer wall and which correspond to the sole-side plastic fastening elements (for instance an inside thread), the inside diameter of the plastic sleeve being at least as large as the outside diameter of the sole-side metal bush, in such manner that for the assembled state of the gripper, the plastic sleeve can be fitted over the sole-side metal bush.
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.
