Abstract

Abstract The present invention teaches a novel, cushioned insole for footwear such as shoes, boots or the like. The insole comprises a multi-layered laminate that has a periphery which conforms generally to the shape of the inside surface of the sole of the footwear so that the insole may be readily placed in and removed from the footwear. The laminate preferably consists of a central, spongy core made of a foamed plastic material which is covered on its upper surface by a thin layer of generally fluid impervious plastic. The lower surface of the central core is covered with a thin layer of a fibrous material, such as paper. Three raised portions are provided which extend upwardly from the upper surface of the laminate. The first raised portion is located proximate the inner peripheral edge of the insole and extends generally longitudinally with respect thereto so as to provide support for the wearer's arch. The second raised portion is generally oval in shape with the major axis thereof extending longitudinally with respect to the insole and is placed such that it provides support for the wearer's metatarsis. The third raised portion extends generally transversely of the longitudinal axis of the insole and provides support for the wearer's phalanges. The laminate comprising the present invention is approximately 0.250 inches thick in the area thereof that is not raised, while the raised areas are not thicker than 0.375 inches. In the embodiment illustrated, the raised portion that supports the wearer's arch is the thickest while the raised portion that supports the wearer's phalanges is the thinnest of the three raised portions.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 339 words
A cushioned insole for use with footwear such as a shoe, a boot or the like, said insole comprising: a multi-layered laminate having a periphery conforming generally to the shape of the inside surface of the sole of the footwear, a first raised portion extending upwardly from the upper surface of said laminate and located so as to provide support for the wearer's arch, a second raised portion extending generally upward from the upper surface of said laminate and located so as to provide support for the wearer's metatarsis, and a third raised portion extending upwardly from the upper surface of said laminate and located so as to provide support for all of the wearer's phalanges, said insole extending along a central longitudinal axis from a relatively narrow unraised heel portion starting at a rearward heel end, to an unraised arch mid-section thereof, thereafter to a gradually transversely wider unraised phalanges section, and ultimately to a forward to end, an outer edge of the insole along said wider phalanges section lying generally closer to said longitudinal axis than an inner edge opposite said outer edge, said first raised portion extending from said inner edge along said mid-section and said heel portion to points less than half the distance toward the outer edge, said second raised portion being spaced from said first raised portion and said outer and inner edges such that unraised mid-section surfaces are disposed therebetween, said second raised portion having a generally elliptical peripheral shape and being disposed substantially mid-length between said heel and toe ends, said third raised portion extending generally transversely entirely across said longitudinal axis and interconnecting said outer and inner edges at said phalanges section, said laminate being comprised of a spongy, central core layer, a thin plastic layer secured to the upper surface of said central layer and a thin layer of fibrous material secured to the lower surface of said central layer, and wherein the thickness of said first raised portion exceeds the thickness of said second and third raised portions.
Claim 2
Dependent Claim 339 words
A cushioned insole for use with footwear such as a shoe, a boot or the like, said insole comprising: a multi-layered laminate having a periphery conforming generally to the shape of the inside surface of the sole of the footwear, a first raised portion extending upwardly from the upper surface of said laminate and located so as to provide support for the wearer's arch, a second raised portion extending generally upward from the upper surface of said laminate and located so as to provide support for the wearer's metatarsis, and a third raised portion extending upwardly from the upper surface of said laminate and located so as to provide support for all of the wearer's phalanges, said insole extending along a central longitudinal axis from a relatively narrow unraised heel portion starting at a rearward heel end, to an unraised arch mid-section thereof, thereafter to a gradually transversely wider unraised phalanges section, and ultimately to a forward to end, an outer edge of the insole along said wider phalanges section lying generally closer to said longitudinal axis than an inner edge opposite said outer edge, said first raised portion extending from said inner edge along said mid-section and said heel portion to points less than half the distance toward the outer edge, said second raised portion being spaced from said first raised portion and said outer and inner edges such that unraised mid-section surfaces are disposed therebetween, said second raised portion having a generally elliptical peripheral shape and being disposed substantially mid-length between said heel and toe ends, said third raised portion extending generally transversely entirely across said longitudinal axis and interconnecting said outer and inner edges at said phalanges section, said laminate being comprised of a spongy, central core layer, a thin plastic layer secured to the upper surface of said central layer and a thin layer of fibrous material secured to the lower surface of said central layer, and wherein the thickness of said first raised portion exceeds the thickness of said second and third raised portions.
