ABSTRACT:
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 attachment device is of the sling-type, full-sole unit and is formed of an elastic, flexible and severable material. 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. The attachment assemblies enable the device to be releasably mounted on the primary footwear irrespective of whether the device is converted from the full-sole unit to the half-sole unit or not. The sole and heel portions of the full-sole unit each include plural hard, ice-gripping projections, e.g., spikes.
