Abstract
Abstract An independent insole assembly embodying an insole attachment member, or both insole and sole attachment members, each of which is integrally formed with depending pegs or clips for connection to spaced resilient means or springs that are interposed between the insole attachment member and a shoe sole, or between the two attachment members in the case where both insole and sole attachment members are used. The assembly is adapted to be incorporated in and connected to a shoe sole and upper during its manufacture and assembly of a shoe thereby to become an integral part of the shoe, with the resilient means or springs projecting upwardly from the shoe sole and resiliently supporting the independent insole assembly thereon. The insole attachment member has a foot-supporting portion and upstanding side portions which embrace the sides and heel of the wearer's foot to protect them from direct friction with the shoe upper during use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
An insole assembly unit, for embodiment in an article of footwear including a sole and a shoe upper, comprising a semi-flexible insole attachment member disposed to form at least the foot-supporting portion of the insole of a shoe, a second, semi-flexible attachment member spaced from said insole attachment member and disposed to be secured to the sole of a shoe, a plurality of spaced, resiliently compressible elements secured to and extending between said members, and means for securing said second member to the sole of a shoe whereby said elements support said insole attachment member movably and resiliently above said sole in a finished shoe, one of said members having thereon spaced multiple clip means integrally arranged on a surface opposed to the other member, and said other member having thereon spaced, multiple, vertically disposed integral peg means aligned with and opposed to said clip means, and each of said resilient elements being releasably attached at one end to one of said clip means and being sleeved at its opposite end over one of said peg means, whereby said elements are disposed between and interconnect said attachment members.
Claim 2
Dependent Claim
188 words
An insole assembly unit, for embodiment in an article of footwear including a sole and a shoe upper, comprising a semi-flexible insole attachment member disposed to form at least the foot-supporting portion of the insole of a shoe, a second, semi-flexible attachment member spaced from said insole attachment member and disposed to be secured to the sole of a shoe, a plurality of spaced, resiliently compressible elements secured to and extending between said members, and means for securing said second member to the sole of a shoe whereby said elements support said insole attachment member movably and resiliently above said sole in a finished shoe, one of said members having thereon spaced multiple clip means integrally arranged on a surface opposed to the other member, and said other member having thereon spaced, multiple, vertically disposed integral peg means aligned with and opposed to said clip means, and each of said resilient elements being releasably attached at one end to one of said clip means and being sleeved at its opposite end over one of said peg means, whereby said elements are disposed between and interconnect said attachment members.
Claim 3
Dependent Claim
52 words
An insole assembly unit as defined in claim 1, wherein said insole attachment member has upstanding side portions projecting upwardly from the foot-supporting portion thereof and contoured to protect the heel and sides of a foot from direct friction with the shoe upper during use of the unit in a finished shoe.
Claim 4
Dependent Claim
29 words
An insole assembly unit according to claim 1, wherein said attachment members are generally contoured as said sole and shoe upper and are disposed to be interfitted therewith, respectively.
Claim 5
Dependent Claim
34 words
An insole assembly unit according to claim 1, wherein said spaced clip means and peg means are arranged in accordance with the weight and contour requirements of a shoe, and generally in spaced rows.
Claim 6
Dependent Claim
50 words
An insole assembly unit according to claim 1, wherein said resilient elements are coil springs and each of said clip means is indented for flexibly interengaging at least the outermost convolution at said one end of each of said coil springs for clamping that end to the associated attachment member.
Claim 7
Dependent Claim
55 words
An insole assembly unit according to claim 5, wherein each of said peg means is cylindrical and has radially projecting integral flexible tabs adjacent the outer end thereof, whereby when a coil spring is sleeved thereover said tabs will inter-engage the end convolutions of said spring to connect the spring to the associated attachment member.
Claim 8
Dependent Claim
29 words
An insole assembly unit according to claim 1, wherein said attachment members are formed with spaced, transversely extending flexure grooves formed in a downwardly disposed face of each member.
