Abstract

Abstract The instant invention is a one piece thong constructed from a flexible base. A cut line along the front of the base provides an upwardly extending tab for insertion between the first and second toe. The tab is shaped to conform to the toes and uses an enlarged upper portion for securing the base to the foot. A second cut disposed along the back of the base provides a flexible strap for securement around the heel of the foot. In the preferred use, the heel strap couples directly to the toe tab providing a slip-on thong by forming a strap that fits over the bridge of the foot.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 342 words
An improved thong characterized by a base having an outer perimeter edge shaped to accommodate the heel and toes of a human foot, said base having a toe tab for insertion between the first and second toe and a heel strap being of such configuration as to cooperatively secure to said toe tab, the improvement comprising: a base constructed from a first sheet of low density foam rubber material bonded to a second sheet constructed from high density foam rubber material forming an upper surface and a lower surface, said first sheet providing a cushioned walking surface and said second sheet providing abrasion resistance and traction on slippery ground surfaces, a toe tab shaped like a human toe and formed integral to said base, said toe tab defined by a space apart first and second cut line connecting said upper and lower surface, each cut line extending inwardly approximately 40 mm from said outer perimeter edge toward a middle section a first distance terminating in a circular hole along a distal end forming a flexible hinge allowing said toe tab to lay flat or bend upwardly, said heel strap formed integral to said base defined by a U-shaped opening connecting said upper and lower surface placed inboard said perimeter edge along a heel portion of said base and extending toward said middle section approximately 95 mm, said opening separating said heel portion from said heel strap a fixed distance with a first and second end of said opening terminating in a circular hole and a heel cutout placed in said heel strap along an edge of said U-shaped opening, said heel cutout having a shape and width to accommodate the tendon of a human foot with said cutout extending outwardly from said U-shaped opening leading to a centrally disposed tear drop shaped coupling hole; whereby said heel cutout allows for securing said heel strap to said toe tab or securing said heel strap to the heel of a wearer with said cutout having a shape accommodating the tendon of a human's foot.
Claim 2
Dependent Claim 342 words
An improved thong characterized by a base having an outer perimeter edge shaped to accommodate the heel and toes of a human foot, said base having a toe tab for insertion between the first and second toe and a heel strap being of such configuration as to cooperatively secure to said toe tab, the improvement comprising: a base constructed from a first sheet of low density foam rubber material bonded to a second sheet constructed from high density foam rubber material forming an upper surface and a lower surface, said first sheet providing a cushioned walking surface and said second sheet providing abrasion resistance and traction on slippery ground surfaces, a toe tab shaped like a human toe and formed integral to said base, said toe tab defined by a space apart first and second cut line connecting said upper and lower surface, each cut line extending inwardly approximately 40 mm from said outer perimeter edge toward a middle section a first distance terminating in a circular hole along a distal end forming a flexible hinge allowing said toe tab to lay flat or bend upwardly, said heel strap formed integral to said base defined by a U-shaped opening connecting said upper and lower surface placed inboard said perimeter edge along a heel portion of said base and extending toward said middle section approximately 95 mm, said opening separating said heel portion from said heel strap a fixed distance with a first and second end of said opening terminating in a circular hole and a heel cutout placed in said heel strap along an edge of said U-shaped opening, said heel cutout having a shape and width to accommodate the tendon of a human foot with said cutout extending outwardly from said U-shaped opening leading to a centrally disposed tear drop shaped coupling hole; whereby said heel cutout allows for securing said heel strap to said toe tab or securing said heel strap to the heel of a wearer with said cutout having a shape accommodating the tendon of a human's foot.
Claim 3
Dependent Claim 37 words
