Slip resistant expansion overshoe
A slip resistant overshoe allowing expansion between a toe section and a heel section to allow a variety of shoe sizes and types to be inserted. The overshoe is formed from a sole having a flexible shank connected to an upper member. The upper member includes a front section and a rear section with opposing side sections therebetween. Each of the opposing side sections and flexible shank includes a corrugated shape to allow expansion of a distance between the front and rear section; a flatter surface resulting in greater slip resistance. Channels formed along a toe section and heel section expand and contract to expel debris providing an anti-clog function to maintain material slip resistance of the overshoe.
1. An overshoe comprising:
a one piece molded member defined by an upper member having a front section spaced apart from a rear section by opposing side sections, said side sections having a plurality of ridges and grooves, and a sole portion having a toe section positioned beneath said upper member and spaced apart from a heel section positioned beneath said rear section;
a shank having a plurality of ridges and grooves formed integral to said member and positioned between said toe section and said heel section, said shank and said side sections forming a continuous U-shaped corrugated section, said ridges and grooves are constructed and arranged to stretch substantially the same across said shank and said opposing side sections forming said corrugated section, and diminish in stretch along each said side section extending from a rear edge of said shank towards said heel portion, and diminish in stretch along said side section extending from a front edge of said shank towards said toe section;
wherein said corrugated section having ridges and grooves of equal shape that are constructed and arranged to allow the stretching of said member between said front section and said rear section and said toe section and said heel section.
2. The overshoe of claim 1 wherein said corrugated section having a material thickness of about 1.5 mm thick formed from said ridges and grooves alternating between an inner surface and an outer surface about 5.0 mm width.
3. The overshoe of claim 1 wherein said ridges and grooves on said side sections are constructed and arranged to have a diminishing width extending from a rear edge of said shank towards said heel portion, and from a front edge of said shank towards said toe portion.
4. The overshoe of claim 1 wherein each said shank is indented from said heel section and said toe section by about 3.5 mm.
5. The overshoe of claim 1 wherein each said toe section and said heel section is about 2.0 mm thick.
6. The overshoe of claim 1 , wherein said ridges and grooves of said shank are of varying heights and widths.
7. The overshoe of claim 1 wherein including a connecting band extending between said front section and said rear section along an upper edge of each said side sections, said connecting band of a predetermined stretch length.
8. The overshoe of claim 1 , wherein said toe section and said heel section include a non-slip tread design of a slip resistant material.
9. The overshoe of claim 8 wherein said slip resistant material has a hardness of about 0.49 Shore.
10. The overshoe of claim 8 includes a plurality of channels formed along said toe section and said heel section, each said channel is constructed and arranged to expand and contract to provide active cleaning of the channels by expelling debris for maintaining slip resistance of the overshoe.
