Abstract
Abstract A shoe having an upper and a sole molded thereon with a disc molded in and rotatable in said sole and having a ground-engaging pad secured thereto and the method of coating the disc with a releasing agent, supporting the disc in the sole mold together with the upper so that the injection of sole material forms a sole bonded to the upper with the disc molded therein but because of the releasing agent is rotatable. This abstract is not to be construed in any way to define or limit the invention set forth below.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
61 words
The method of making a shoe, including the steps of forming an upper on a last, positioning the last with the upper thereon and a ground engaging pad in a mold, and injecting material into the mold to form a sole bonded to the upper and to connect to the ground engaging pad which is in rotating engagement with the sole.
Claim 2
Independent Claim
61 words
The method of making a shoe, including the steps of forming an upper on a last, positioning the last with the upper thereon and a ground engaging pad in a mold, and injecting material into the mold to form a sole bonded to the upper and to connect to the ground engaging pad which is in rotating engagement with the sole.
Claim 3
Independent Claim
118 words
The method of making a shoe including the steps of forming the upper on a last, positioning the last with the upper thereon in a mold, coating a portion of a disc with a release agent, supporting said disc within the sole cavity defined in said mold in spaced relation to said last, said disc being in a plane generally parallel with said insole, and injecting sole material into said mold to form a sole bonded to said upper, said disc being imbedded and rotatable in said sole and having a circular pad of sole material attached to its central portion so that said pad rotates in a recess in the sole with the rotation of said plate.
Claim 4
Independent Claim
118 words
The method of making a shoe including the steps of forming the upper on a last, positioning the last with the upper thereon in a mold, coating a portion of a disc with a release agent, supporting said disc within the sole cavity defined in said mold in spaced relation to said last, said disc being in a plane generally parallel with said insole, and injecting sole material into said mold to form a sole bonded to said upper, said disc being imbedded and rotatable in said sole and having a circular pad of sole material attached to its central portion so that said pad rotates in a recess in the sole with the rotation of said plate.
Claim 5
Dependent Claim
43 words
The method of making a shoe according to claim 2 including the step of coating the central portion of the lower side of said disc with a bonding agent so that injected sole material bonds to said disc to provide said circular pad.
Claim 6
Dependent Claim
50 words
The method of making a shoe according to claim 3 including the step of separating the sole material bonded to said disc from the remainder of injected sole material to form a circular pad of said material which rotates with said disc relative to the remainder of said sole material.
Claim 7
Dependent Claim
51 words
The method of making a shoe according to claim 2 including the step of isolating A space below the central portion of said disc prior to said injection step whereby sole material is excluded during said injection step to provide a circular recess in the sole formed by said injection step.
Claim 8
Dependent Claim
35 words
The method of making a shoe according to claim 2 including the step of securing a traction material to the central portion of said disc for rotation therewith at least partially within said circular recess.
Claim 9
Independent Claim
51 words
The method of making a shoe including the steps of supporting a disc within a sole mold cavity, injecting sole material into said cavity to form a sole said disc rotatably imbedded therein with a ground-engaging pad attached to said disc for rotation therewith, and attaching the sole to an upper.
Claim 10
Independent Claim
51 words
The method of making a shoe including the steps of supporting a disc within a sole mold cavity, injecting sole material into said cavity to form a sole said disc rotatably imbedded therein with a ground-engaging pad attached to said disc for rotation therewith, and attaching the sole to an upper.
Claim 11
Dependent Claim
39 words
A shoe, comprising an upper, a sole attached to said upper, and a ground engaging pad, one of said sole and said pad being molded to the other whereby said pad is retained in rotating engagement with said sole.
Claim 12
Dependent Claim
39 words
A shoe, comprising an upper, a sole attached to said upper, and a ground engaging pad, one of said sole and said pad being molded to the other whereby said pad is retained in rotating engagement with said sole.
Claim 13
Dependent Claim
88 words
A shoe comprising an upper, a sole attached to said upper, a disc molded in said sole, said disc being approximately positioned at the ball of the wearer''s foot and extending in a plane parallel to the bottom of said sole, said disc being rotatable within said sole, said sole defining a circular recess beneath the central portion of said disc, a ground-engaging pad, and means for attaching said traction pad to said disc so that said pad is free to rotate with said disc in said recess.
Claim 14
Dependent Claim
88 words
A shoe comprising an upper, a sole attached to said upper, a disc molded in said sole, said disc being approximately positioned at the ball of the wearer''s foot and extending in a plane parallel to the bottom of said sole, said disc being rotatable within said sole, said sole defining a circular recess beneath the central portion of said disc, a ground-engaging pad, and means for attaching said traction pad to said disc so that said pad is free to rotate with said disc in said recess.
Claim 15
Dependent Claim
24 words
A shoe according to claim 9 wherein said attaching means includes bonding said pad to the central portion of the bottom of said disc.
Claim 16
Dependent Claim
34 words
