Abstract
Abstract A flexible shoe insole consisting of strips of narrow bands of wood spaced from each other and fixed to a pliable underlying support. The strips are oriented with the length of the strip being transverse to the longitudinal axis of the foot and the operative connection to the pliable underlying substrate allows flexure of the insole for beneficial support while the choice of materials associated with the insole allows aspiration of the foot as well as thermal protection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A flexible insole to be placed within a shoe, boot or the like comprising in combination: a flexible substrate dimensioned to be received within the shoe, a plurality of wooden slats having bottom faces fastened to an upper surface of said substrate, each slat oriented parallel to one another and transverse to the longitudinal axis of the shoe, and each slat spaced from an adjacent slat, whereby upper faces of said slats come in direct contact with the bottom surface of a person's foot wearing the shoe and said slats can articulate one relative to another to accommodate foot flexure while allowing proper thermal aspiration of the foot, wherein said spaces between adajcent slats is constant for all slats, wherein top longitudinal edges of said wooden slats are provided with a contoured surface whereby articulation of adjacent slats precludes pinching of the skin of the foot supported thereon, and wherein said flexible substrates includes portions thereof interposed between adjacent side faces of said wooden slats.
Claim 2
Dependent Claim
165 words
A flexible insole to be placed within a shoe, boot or the like comprising in combination: a flexible substrate dimensioned to be received within the shoe, a plurality of wooden slats having bottom faces fastened to an upper surface of said substrate, each slat oriented parallel to one another and transverse to the longitudinal axis of the shoe, and each slat spaced from an adjacent slat, whereby upper faces of said slats come in direct contact with the bottom surface of a person's foot wearing the shoe and said slats can articulate one relative to another to accommodate foot flexure while allowing proper thermal aspiration of the foot, wherein said spaces between adajcent slats is constant for all slats, wherein top longitudinal edges of said wooden slats are provided with a contoured surface whereby articulation of adjacent slats precludes pinching of the skin of the foot supported thereon, and wherein said flexible substrates includes portions thereof interposed between adjacent side faces of said wooden slats.
Claim 3
Dependent Claim
12 words
The device of claim 1, wherein said contoured surface is a bevel.
Claim 4
Dependent Claim
11 words
The device of claim 1, wherein said contoured surface is rounded.
Claim 5
Dependent Claim
11 words
The device of claim 1, wherein said contoured surface is angular.
Claim 6
Dependent Claim
20 words
The device of claim 1, wherein said interposed portions extend up to the top planar surface of said wooden slats.
Claim 7
Dependent Claim
16 words
The device of claim 1, wherein spaces are provided on each side of said interposed portions.
Claim 8
Dependent Claim
22 words
The device of claim 1, wherein the height of each slat varies in accordance with the anatomical configuration of a person's foot.
Claim 9
Dependent Claim
21 words
The device of claim 7, wherein the width of adjacent slats varies in accordance with variations in flexure of the foot.
