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. The ceramic insert is surrounded over a part of its length by a metal sleeve which is also embedded into the body portion 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.
