ABSTRACT:
A gripping element for a sports shoe comprises a body portion of plastic material and a ceramic insert which is embedded into the body portion and which provides the ground-engaging surface of the element.

At least on its outside peripheral surface around which the metal sleeve extends, the ceramic insert has surface configurations such as annular ribs and/or grooves to provide a positive connection to the plastic material therearound, with a layer of plastic material between the ceramic insert and the metal sleeve.
