Insole with moldable material

Claim 2

An insole for an item of footwear having a medial and a lateral side and comprising: a shoeboard having a profile which generally conforms to the outline of the foot of a wearer and flexible to bend with the footwear item; a soft, flexible innersole piece above the shoe board; a mass of flexible, moldable, nonsetting material contained between the shoe board and the innersole piece, for causing the innersole piece to conform to the bottom of the foot of a wearer of the footwear; connection means for securing the shoe board and the innersole piece together so as to contain and seal the nonsetting material between them, comprising an overlap of the innersole piece over the shoe board around its periphery, the overlap being tucked under the shoe board and glued to the underside thereof, and stitching from the innersole down through the shoe board, the stitching being inward a short distance from the edge of the insole and being in one general arc in front of the wearer's first toe and in another generally arcuate pattern at the heel, thereby preventing the moldable nonsetting material from excessive molding and migration beyond the stitching in those locations; the innersole piece being free of stitching at the forefoot on either side of the ball of the foot, and at the cuboid bone at the lateral midfoot back to just forward of the heel, whereby the nonsetting material is allowed to mold and flow out to the periphery of the insole in these areas.

Claim 3

The insole of claim 1, wherein the stitching at the heel extends through at least a generally semicircular configuration.

Claim 4

The insole of claim 1, wherein the stitching at the heel extends from just forward of the center of the heel bone of the wearer's foot at the lateral side of the insole, through a generally semicircular configuration and farther forward at the medial side of the insole to about one inch ahead of the center of the heel bone.

Claim 5

The insole of claim 1, wherein the stitching is spaced about 3/16 inch to about 1/4 inch inward from the edge of the insole.

Claim 6

The insole of claim 1, wherein the arc of stitching at the toe extends through about 11/2 inches.

Claim 7

The insole of claim 1, wherein the insole includes a medial arch pad, glued to the underside of the shoe board.

Claim 8

The insole of claim 1, wherein the insole is permanently affixed in the item of footwear, with the shoe board glued down to the sole of the footwear.

Claim 9

The insole of claim 1, further including a relatively stiff base subsole glued to the underside of the shoe board for increased stability of the insole as a replacement insole, the stitching passing through the innersole piece, the shoe board and the base subsole.

Claim 10

An insole for placement in an item of footwear to replace an existing insole, said insole having a medial side and a lateral side, comprising: a relatively stiff base subsole or shoe board as a bottom for the insole, having a profile which generally conforms to the outline of the foot of a wearer and flexible to bend with the footwear item; a flexible upper subsole or upper shoe board above the base subsole; a soft, flexible innersole piece above the upper subsole; a mass of flexible, moldlable, nonsetting material contained between the upper subsole and the innersole piece, for causing the innersole piece to conform to the bottom of the foot of a wearer of the footwear; connection means for securing the base subsole, the upper subsole and the innersole piece together so as to contain and seal the nonsetting material between the upper subsole and the innersole piece, comprising an overlap of the innersole piece over the upper subsole around its periphery, the overlap being tucked under the upper subsole and glued to the underside thereof, and the base subsole being glued to the upper subsole and the innersole overlap, and stitching from the innersole piece down through the upper subsole and the base subsole, the stitching being inward a short distance from the edge and parallel to the profile of the insole and being only in two areas, a first said area being at the toe and being in one general arc in front of at least the wearer's first toe and a second said area being at the heel in a generally arcuate pattern at the heel, thereby preventing the moldable nonsetting material from excessive molding and migration beyond the stitching in those locations; the innersole piece being free of stitching at the forefoot on either side of the ball of the foot, and at the cuboid bone at the lateral midfoot of a wearer back to just forward of the heel, whereby the nonsetting material is allowed to mold and flow out to the periphery of the insole in these areas.

Claim 11

An insole for placement in an item of footwear to replace an existing insole, said insole having a medial side and a lateral side, comprising: a relatively stiff base subsole or shoe board as a bottom for the insole, having a profile which generally conforms to the outline of the foot of a wearer and flexible to bend with the footwear item; a flexible upper subsole or upper shoe board above the base subsole; a soft, flexible innersole piece above the upper subsole; a mass of flexible, moldlable, nonsetting material contained between the upper subsole and the innersole piece, for causing the innersole piece to conform to the bottom of the foot of a wearer of the footwear; connection means for securing the base subsole, the upper subsole and the innersole piece together so as to contain and seal the nonsetting material between the upper subsole and the innersole piece, comprising an overlap of the innersole piece over the upper subsole around its periphery, the overlap being tucked under the upper subsole and glued to the underside thereof, and the base subsole being glued to the upper subsole and the innersole overlap, and stitching from the innersole piece down through the upper subsole and the base subsole, the stitching being inward a short distance from the edge and parallel to the profile of the insole and being only in two areas, a first said area being at the toe and being in one general arc in front of at least the wearer's first toe and a second said area being at the heel in a generally arcuate pattern at the heel, thereby preventing the moldable nonsetting material from excessive molding and migration beyond the stitching in those locations; the innersole piece being free of stitching at the forefoot on either side of the ball of the foot, and at the cuboid bone at the lateral midfoot of a wearer back to just forward of the heel, whereby the nonsetting material is allowed to mold and flow out to the periphery of the insole in these areas.

Claim 12

The insole of claim 9, wherein the stitching at said second area extends through at least a generally semicircular configuration.

Claim 13

The insole of claim 9, wherein the stitching at said second area extends from just forward of the center of the heel bone of a wearer at the lateral side of the insole, through a generally semicircular configuration and farther forward at the medial side of the insole to about one inch ahead of the center of the heel bone of a wearer.

Claim 14

The insole of claim 9, wherein the stitching is spaced about 3/16 inch to about 1/4 inch inward from the edge of the insole.

Claim 15

The insole of claim 9, wherein the arc of stitching at the toe is between about 11/4 inches and about 21/2 inches in length.

Claim 16

The insole of claim 9, wherein the mass of nonsetting material is in a sheet cut somewhat smaller than the upper shoe board, such that it is spaced inwardly a short distance from the edge of the shoe board.
