Abstract

Abstract A composite outsole has a substantially planar first element with a bottom tread surface, a top surface spaced from the bottom surface, and an outwardly facing side edge extending around the bottom tread surface. A lip extends around the top surface and protrudes laterally beyond the outwardly facing side edge. A second element is molded onto the top surface of the first element. The second element has a peripheral portion overlapping the lip of the first element. An inwardly facing side edge on the peripheral portion is spaced laterally from the outwardly facing side edge of the first element to define a downwardly open groove therebetween.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 172 words
A composite outsole comprising: a substantially planar first element formed of a first material, said first element having a bottom tread surface, a top surface spaced from said bottom surface by the thickness of said first element, an outwardly facing side edge extending around said bottom tread surface, said bottom tread surface being interrupted by a plurality of grooves extending to said side edge, and a lip extending around said top surface, said lip having an underside protruding laterally beyond said side edge; and a second element molded onto the top surface of said first element, said second element consisting of a second material which is different from said first material, said second element having a peripheral portion overlapping said lip in a manner allowing only the underside thereof to remain exposed, said peripheral portion having an inwardly facing side edge spaced laterally from the outwardly facing side edge of said first element to define a downwardly open groove therebetween, with the underside of said lip defining the base of said groove.
Claim 2
Dependent Claim 172 words
A composite outsole comprising: a substantially planar first element formed of a first material, said first element having a bottom tread surface, a top surface spaced from said bottom surface by the thickness of said first element, an outwardly facing side edge extending around said bottom tread surface, said bottom tread surface being interrupted by a plurality of grooves extending to said side edge, and a lip extending around said top surface, said lip having an underside protruding laterally beyond said side edge; and a second element molded onto the top surface of said first element, said second element consisting of a second material which is different from said first material, said second element having a peripheral portion overlapping said lip in a manner allowing only the underside thereof to remain exposed, said peripheral portion having an inwardly facing side edge spaced laterally from the outwardly facing side edge of said first element to define a downwardly open groove therebetween, with the underside of said lip defining the base of said groove.
Claim 3
Dependent Claim 17 words
The composite outsole of claim 1 wherein said lip protrudes above the plane of said top surface.
Claim 4
Dependent Claim 18 words
The composite outsole of claim 1 wherein said peripheral portion protrudes downwardly below the level of said lip.
Claim 5
Dependent Claim 24 words
The composite outsole of claim 3 wherein the lowermost surface of said peripheral portion is spaced vertically above the plane of said tread surface.
Claim 6
Dependent Claim 18 words
The composite outsole of claim 1 wherein said tread surface includes grooves communicating with said downwardly open groove.
