## Abstract

An anti-slip overshoe has a contoured outer band and first gripping pad and second gripping pad disposed interior to the contoured outer band for enhanced traction. A web structure connects the first gripping pad and second gripping pad to the contoured outer band. A plurality of gripping devices is attached to the first gripping pad and second gripping pad for enhanced traction on natural surfaces. The gripping devices includes a body, button extending from a first end of the body, plurality of spikes disposed around a perimeter of the body, and central spike extending from a second end of the body. A neck is disposed around the body between the button and spikes. The spikes include a traction arm, plurality of edges formed along the traction arm, and concave surface between a first edge and second edge along the traction arm.

## Claims
