摘要： An antislip apparatus is provided for footwear to be fit on a region of a sole and/or a heel of a shoe defining an engagement surface in contact with the ground surface. The antislip apparatus includes a ground gripping structure for engaging the ground surface including a support and crampon-like prongs disposed on the support extending perpendicularly from the support. A cam arrangement interacts with the support for moving the prongs to one of a grip position with the prongs extending beyond the level of the engagement surface, or to a rest position with the prongs disposed inwardly of the engagement surface. The cam arrangement includes a plate disposed substantially parallel to the support and cams acting on one of the support and the plate to vary a distance between the support and the plate to move the prongs. An operating arrangement or actuator is provided for operating the cam arrangement. The actuator includes a cylindrical rotor formed integral with the plate. The rotor is disposed perpendicularly to the support and has at a lower end thereof, accessible from a side of the engagement surface, a seat defined by a groove or cut. A holding box element contains the support, the cam arrangement and the actuator. The holding box element is provided one of below or on the engagement surface. The holding box element includes an opening allowing access to the actuator and has one or more slots which the prongs extend through in the grip position.
