  • Patent number: 5025576
    Abstract: The invention describes a sole 1 for sports shoes, and particularly suitable for football, of the type which presents in the sole itself a plurality of recesses for fixing in a reversible fashion an accessory element such as a cleat or a heel. An essential feature of the invention consists of the fact that the element is not screwed as it is conventional to another structure integral with the recesses for fixing the accessory element to the sole, but is screwed to a tongue 6 which is inserted in a slit 4 formed in the recesses for fixing the element to the sole. The tongue 6 remains blocked within the recesses in a position transversal with respect to the slit during the step when the accessory element is being screwed in position.
