Abstract
Abstract A disposable shoe heel protector device is removably affixed to the back of a shoe in an area to cover and protect the rearward part of the shoe that makes sliding contact with the floorboard of an automobile while driving. The protector is made in an oblated configuration and therefore has a long and a short dimension. The protector comprises a flexible main support in the form of an eliptical cutout from a sheet of thin flexible plastic material. The support has an inside surface opposed to an outside surface. Adhesive material coats the inside surface at the opposed marginal ends of the support. A cushion in the form of a thin piece of foam material is attached to the medial inside surface of the support and extends from the adhesive on one side to the adhesive on the opposed side, thereby leaving the centrally located foam material which bears against the shoe surface with the adhesive being located at the opposed ends of the support. The adhesive at the marginal ends of the support releasable attaches the protector device to the outer surface of a shoe. A silicon coated wrapper having the same area and dimension as the adhesive coated part of the support protects the adhesive until the protector is needed. The protector can therefore be stored in stacked relationship until needed, and at that time the wrappers are peeled off to expose the adhesive. The protector is affixed to the shoe heel at the opposed marginal ends thereof by pressing the ends bearing the adhesive to the shoe. The protector device subsequently can be removed and discarded by peeling it off the shoe. The adhesive preferably is arranged at the marginal ends of the long dimension of the oblated cutout. Preferably, the adhesive is applied as a thin coating over the entire inside surface of the cutout, fastens the cushion in place, and leaves the opposed coated marginal ends available for attaching the protector to the rear of the shoe.
