Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A method of manufacturing a segmented clog sole comprising: a. forming a unit sole having at least two slots on the upper side thereof running across the width of said unit sole perpendicular to the longitudinal axis thereof, one of said slots being approximately in the area of the ball and the others being forward thereof towards the toe; b. applying with an adhesive a mid sole to the upper side of said unit sole over said slots and an outer sole to the bottom side thereof; and c. cutting said unit sole and outer sole completely through from the side of said outer sole into said slots with the cuts being in register with and in number corresponding to said slots.
Claim 2
Independent Claim
122 words
A method of manufacturing a segmented clog sole comprising: a. forming a unit sole having at least two slots on the upper side thereof running across the width of said unit sole perpendicular to the longitudinal axis thereof, one of said slots being approximately in the area of the ball and the others being forward thereof towards the toe; b. applying with an adhesive a mid sole to the upper side of said unit sole over said slots and an outer sole to the bottom side thereof; and c. cutting said unit sole and outer sole completely through from the side of said outer sole into said slots with the cuts being in register with and in number corresponding to said slots.
Claim 3
Dependent Claim
68 words
The process of claim 1 wherein said unit sole has a thickness of at least 1/2 inch in the area of the ball, said slots are at least 1/16 inch deep but no deeper than three quarters of the thickness of said unit sole, are at least 1/64 inch wide and are spaced to form approximately equal segments ± 1/4 inch from said one slot to the toe.
Claim 4
Dependent Claim
15 words
The process of claim 1 wherein the number of said slots does not exceed four.
Claim 5
Dependent Claim
18 words
The process of claim 1 wherein an upper is fastened to said unit sole prior to step (c).
Claim 6
Dependent Claim
17 words

Claim 7
Dependent Claim
9 words
A clog made by the process of claim 1.
Claim 8
Independent Claim
110 words
A method of manufacturing a clog sole comprising: forming a unit sole from a monolithic material and applying thereto with an adhesive a flexible mid sole to the upper side and an outer sole to the bottom side, and cutting said unit sole and outer sole completely through from the side of said outer sole with the cuts running across the width of said unit sole generally perpendicular to the longitudinal axis thereof, one of the cuts being approximately in the area of the ball and the others being forward thereof towards the toe and spaced to give approximately equal segments, said segments being held together by said mid sole.
Claim 9
Independent Claim
110 words
A method of manufacturing a clog sole comprising: forming a unit sole from a monolithic material and applying thereto with an adhesive a flexible mid sole to the upper side and an outer sole to the bottom side, and cutting said unit sole and outer sole completely through from the side of said outer sole with the cuts running across the width of said unit sole generally perpendicular to the longitudinal axis thereof, one of the cuts being approximately in the area of the ball and the others being forward thereof towards the toe and spaced to give approximately equal segments, said segments being held together by said mid sole.
