The invention concerns an anti-skid device for footwear in the form of spikes (12,13), said spikes arranged to be displaced backwards and forwards from an inactive position in or interiorly of the undersole (5) of a shoe, out through an opening (14,15) formed in the undersole (5) and to an active anti-skid position on the lover face of the under- sole(5). The anti-skid device comprises a threaded rotary rod (1a, 1b) extending in the longitudinal direction of the undersole (5). The rod is in threaded engagement with a sliding member (3,4) which is displace- able backwards and forwards in the longitudinal direction of the un- dersole (5) and which is hingedly connected to a support element (10, 11) supporting the spikes (12, 13), said spikes projecting from the sup- port element (10,11) in the direction of movement of the latter. The ro- tary rod (1a,1b) is arranged, upon rotation in one sense, to displace the sliding member (3; 4) in one direction lengthwise with respect to the un- dersole (5) to bring said member to displace the spikes (12, 13) out through the opening (14,15) in the sole to the anti-skid position. Upon rotation in he opposite sense the slide member (4; 5) is displaced in the opposite direction and retracts the spikes (12, 13) through the opening (14,15) back into the inactive position:
