Abstract
Abstract A shoe that includes an outsole having a plurality of gripping portions, the locus of the gripping portions defining a path extending from the outermost portion of the shoe below the small toe generally toward the ball of the foot at the large toe, with the portions contacting the ground sequentially along the path as the front portion of the outsole sets down. Also disclosed in providing a shoe outsole with a plurality of channels which have a first narrow region having a first width and an adjacent region having a larger width so as to permit deformable foreign matter such as food that collects in the first region to be discharged into the second region, which is sufficiently wider than the first region as to cause discharge of the matter.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
112 words
A shoe comprising an outsole having a plurality of gripping portions, the locus of said portions defining a path extending from the outermost portion of the shoe below the small toe to the ball of the foot at the large toe, said portions contacting the ground sequentially along said path as the front portion of said outsole sets down, said path defining an arc about a pivot point region of pivoting located at the ball of the foot in the vicinity of the base of the small toe, said gripping portions being separated by elongated channels in the surface of said outsole, said channels extending generally radially from said pivot point region.
Claim 2
Dependent Claim
112 words
A shoe comprising an outsole having a plurality of gripping portions, the locus of said portions defining a path extending from the outermost portion of the shoe below the small toe to the ball of the foot at the large toe, said portions contacting the ground sequentially along said path as the front portion of said outsole sets down, said path defining an arc about a pivot point region of pivoting located at the ball of the foot in the vicinity of the base of the small toe, said gripping portions being separated by elongated channels in the surface of said outsole, said channels extending generally radially from said pivot point region.
Claim 3
Dependent Claim
24 words
The shoe of claim 1, wherein said gripping portions are provided by discrete gripping pads separated by channels in the surface of said outsole.
Claim 4
Dependent Claim
22 words
The shoe of claim 3, wherein said discrete pads are elongated along axes that extend generally radially from said pivot point region.
Claim 5
Dependent Claim
17 words
The shoe of claim 2, wherein said outsole also has a peripheral channel extending along its periphery.
Claim 6
Dependent Claim
25 words
The shoe of claim 3, wherein said outsole also has channels defining arc shaped pads located between said pivot point region and said gripping pads.
Claim 7
Dependent Claim
55 words
The shoe of claim 3, wherein said pads have edges between flat contact regions and transverse faces extending into said outsole, first said edges extending generally along said path, and second said edges extending along radial axes from said pivot point region, said first and second edges meeting at corners that provide good gripping action.
Claim 8
Dependent Claim
12 words
The shoe of claim 1, wherein said outsole has a raised heel.
Claim 9
Dependent Claim
66 words
The shoe of claim 1, wherein said outsole has a plurality of channels which have a first narrow region having a first width and an adjacent second region having a larger width so as to permit matter that collects in said first region to be displaced into said second region, which is sufficiently wider as to cause discharge of said matter during flexing of said outsole.
Claim 10
Dependent Claim
139 words
A shoe comprising an outsole having a plurality of channels defined by side walls extending along opposite sides of channel axes, each said channel axis extending generally radially from a pivot point region of pivoting located on the ball of the foot in the vincinity of the base of the small toe, said channels each having a first narrow region having a first width and an adjacent second region having a larger width, said side walls in said second region each being spaced from its respective said axis by a larger distance than the distance from said axis to side walls in said first region, so as to permit matter that collects in said first region to be displaced into said second region, which is sufficiently wider as to cause discharge of said matter during flexing of said outsole.
Claim 11
Dependent Claim
139 words
A shoe comprising an outsole having a plurality of channels defined by side walls extending along opposite sides of channel axes, each said channel axis extending generally radially from a pivot point region of pivoting located on the ball of the foot in the vincinity of the base of the small toe, said channels each having a first narrow region having a first width and an adjacent second region having a larger width, said side walls in said second region each being spaced from its respective said axis by a larger distance than the distance from said axis to side walls in said first region, so as to permit matter that collects in said first region to be displaced into said second region, which is sufficiently wider as to cause discharge of said matter during flexing of said outsole.
Claim 12
Dependent Claim
12 words
The shoe of claim 10, wherein said channels are between discrete pads.
Claim 13
Dependent Claim
28 words
The shoe of claim 10, wherein said pads are arranged in pairs in such a manner that said channels are located between the pads that comprise each pair.
Claim 14
Dependent Claim
32 words
The shoe of claim 10, wherein said pads are rectangularly shaped and extend along radial axes from the region at the ball of the foot near the base of the small toe.
Claim 15
Dependent Claim
17 words
The shoe of claim 10, wherein said channels have two wider regions adjacent to said first region.
Claim 16
Dependent Claim
31 words
The sole of claim 9, wherein said second region is tapered so that the section adjacent to said first region is wider than the section further away from said first region.
Claim 17
Dependent Claim
12 words
The shoe of claim 9, wherein said outsole has a raised heel.
