Abstract
An anti-slipping attachment for shoes is disclosed in two embodiments, one for both the sole and heel and the other for the sole alone. The sole portion of each embodiment includes a pair of overlapped plates pivotted together at their rear ends permitting adjustment of the width of the device at its front end. One plate includes an integral tab bent over the other plate to serve as a guide and the other plate includes an integral stop which cooperates with the tab to limit the maximum angular displacement of the plates. The plates, which have integral teeth and integral apertured ears for receiving a strap, are each formed by bending from identical sheet metal blanks.

- a pair of at least partially overlapped plates, each of said plates having a front end located at the front end of said device and a rear end;
- means, proximate the rear ends of said plates, for pivotting together said plates for relative rotation along each other, enabling adjustment of the width spanned by the front ends of said plates;
- integral teeth projecting generally perpendicularly downward from the peripheries of said plates;
- one of said plates having integral guide means extending from its front end and about the other plate for maintaining the front ends of said plates against each other;
