ABSTRACT:
In a gripping element for sports shoes consisting of a cleat having a base portion formed on a sole or fastened to it and that is made of stiffly, elastic material with an insert projecting beyond the base portion that is made of a rigid, highly abrasion resistant material. To reduce the danger of destruction of the insert, particularly by shearing forces, the insert is formed so that the ratio of the maximum diameter (D) of the insert (3) relative to its total height (H) is about 1:7.5 to 1:1.8, the insert (3), in its midsection, has a constriction (E) that divides insert (3) into a tread section (4) and a fastening section (5), the height of the constriction (E) is 25% to 60% of the total height (H) and so that the smallest diameter (e) of constriction (E) is 75% to 45% of maximum diameter (D) of the tread section (4), whereby the insert is able to resiliently deflect so as to move sideways with elastic deformation of the base due to radially imposed loads.
