Abstract: In an anti-slipping device for a shoe sole having an anti-slipping or anti-sliding component such as nails or spikes which are not secured to the sole but are secured on support elements which can be overturned to be hidden in slots made on the sole itself, each overturning support element is hinged at its ends on cubic blocks which are anchored to the sole due to a mushroom-shaped coupling element which is molded in once piece to the cubic block itself, made of the same thermo-polyurethane material as the support elements and which is snap-fitted in its seat arranged in the sole next to the slot where the overturning support element is accommodated after the overturning, without interfering with the integrity of the sole itself and thus allowing the replacement thereof without difficulty. Also included is a mechanism for avoiding the accidental loss of the support element when walking.
