An convertible, footwear attachment device and methods of configuring it and using it on a primary footwear to provide resistance to slippage on snow, ice or other slick surfaces.

The full sole unit is made up of a sole, a toe attachment assembly, a heel attachment assembly, and visible indicia, e.g., grooves, for indicating the boundaries of a removable portion of the full-sole unit which may be severed therefrom to form the half-sole unit.
