US4688338A — Orthotic insert for high heeled shoes

Claim 1

Independent Claim 184 words

A substantially unitary orthotic insert adapted to be placed in an article of footwear, said insert having a longitudinal axis parallel to a lengthwise axis of a foot for which the insert is used, and a transverse axis, said insert comprising: a. a rear portion adapted to underlie and engage a plantar surface of a cacaneal area of the foot; b. a forward portion adapted to underlie and engage a plantar surface of a metatarsal head area of the foot; c. an intermediate portion connecting to and extending between said rear and forward portions to engage a plantar surface of a mid-foot area of the foot; d. said insert having outside and inside edge portions adapted to be positioned adjacent an outside edge and an inside edge of the foot, respectively; e. said insert having a laminated structure comprising a plurality of vertically stacked layers bonded to one another to form a substantially unitary structure, said laminated structure comprising: 1. first laminate means having an internal material structure adapted to resist bending moments generally uniformly about both of said longitudinal and transverse axes; 2.

Claim 2

Dependent Claim 184 words

A substantially unitary orthotic insert adapted to be placed in an article of footwear, said insert having a longitudinal axis parallel to a lengthwise axis of a foot for which the insert is used, and a transverse axis, said insert comprising: a. a rear portion adapted to underlie and engage a plantar surface of a cacaneal area of the foot; b. a forward portion adapted to underlie and engage a plantar surface of a metatarsal head area of the foot; c. an intermediate portion connecting to and extending between said rear and forward portions to engage a plantar surface of a mid-foot area of the foot; d. said insert having outside and inside edge portions adapted to be positioned adjacent an outside edge and an inside edge of the foot, respectively; e. said insert having a laminated structure comprising a plurality of vertically stacked layers bonded to one another to form a substantially unitary structure, said laminated structure comprising: 1. first laminate means having an internal material structure adapted to resist bending moments generally uniformly about both of said longitudinal and transverse axes; 2.

Claim 3

Dependent Claim 86 words

a second laminate means comprising at least one layer having fibers which are generally aligned with said longitudinal axis so as to provide greater resistance to bending moments along said longitudinal axis, and less resistance to bending along said transverse axis; 3. a third laminate means comprising at least one layer comprising fibers generally aligned with said longitudinal axis, and being positioned along the outside edge portion of said insert so as to provide greater resistance to bending moments along the longitudinal axis at the outside

Claim 4

Dependent Claim 86 words

a second laminate means comprising at least one layer having fibers which are generally aligned with said longitudinal axis so as to provide greater resistance to bending moments along said longitudinal axis, and less resistance to bending along said transverse axis; 3. a third laminate means comprising at least one layer comprising fibers generally aligned with said longitudinal axis, and being positioned along the outside edge portion of said insert so as to provide greater resistance to bending moments along the longitudinal axis at the outside

Claim 5

Dependent Claim 80 words

edge portion of the insert. 2. The insert as recited in claim 1, wherein there is fourth laminate means comprising at least one layer having a plurality of generally parallel fibers, which have a predominant orientation of alignment about a direction extending from a rear outside location to a forward inside location, so as to provide greater resistance to bending moments along an axis extending from a rear outside location to a forward inside location generally parallel to said orientation.

Claim 6

Dependent Claim 38 words

The insert as recited in claim 2, wherein said fourth laminate means has a width dimension narrower than that of the insert, whereby said resistance to bending moments is localized relative to the width dimension of the insert.

Claim 7

Dependent Claim 19 words

The insert as recited in claim 3, wherein said fourth laminate means is generally centralized relative to said insert.

Claim 8

Dependent Claim 49 words

The insert as recited in any of claims 1, 2, 3 or 4, wherein said third laminate means has a length dimension less than a length dimension of the insert, with a forward end of said third laminate means terminating at a location rearwardly of a forward end of

Claim 9

Dependent Claim 20 words

The insert as recited in any one of claims 1, 2, 3 or 4, wherein said fibers comprise graphite fibers.
