The invention relates to an anti-slip device, which can be fixed to a shoe bottom. The studs 2 of the anti-slip device are fixed to flexible straps 3, which can be raised or lowered in relation to the plane of the shoe bottom by means of wedge surfaces 9, which either wedge in under the straps 3 or away from under the straps 3, when the straps 3 and the wedge surfaces 9 are displaced in relation to one another. The anti-slip device part provided with studs 2 may be rotatable about the central axis in order to deploy or retract the studs 2. <IMAGE>
