Orthotic insole for a woman's shoe
An orthotic insole comprising top, middle, and bottom layers. The top layer is in contact with a wearer's foot or a wrap of material, the bottom layer is adjacent to an outsole of the shoe, and the middle layer is positioned therebetween. The top layer has substantially the same width and length of the entire insole. The middle layer is a generally j-shaped strip which provides a rearfoot posting within the insole and a cupping effect to a wearer's heel. The middle layer may have a similar overall width as the top layer but may include a shorter length than the top layer such that the middle layer only extends from the heel to approximately the joint of the fifth metatarsal bone. The bottom layer may be more rigid than the other two layers, and may further include a rigid plate. The insole may further include an arch support integrally formed within one or more of the layers or a cushioning layer with one or more cushioning segments on top of the top layer.
1. An insole, comprising:
a top layer;
a middle layer, wherein the middle layer comprises a first straight portion and a curved portion adjacent to the straight portion, wherein the first straight portion is positioned along a lateral edge of the insole that corresponds to a lateral edge of a wearer's foot and the curved portion is positioned adjacent the back of the insole that corresponds to a wearer's heel; and
a bottom layer, wherein the bottom layer is a base positioned directly beneath the entire middle layer, the bottom layer having a first width,
wherein the entire insole extends a first length, wherein an entire length of the middle layer that extends along the lateral edge of the insole is a second length and the entire length of the middle layer that extends along the lateral edge is a second width that is less than the first width of the bottom layer, wherein an entire length of the middle layer that extends along a medial edge of the insole that corresponds to a medial edge of a wearer's foot is a third length, wherein the first length and second length are substantially similar, and wherein the third length is less than the first or second lengths.
2. The insole of claim 1 , wherein the insole further includes an arch support along a medial edge of the insole.
3. The insole of claim 2 , wherein the top layer includes a protrusion that corresponds to the arch support, and wherein the bottom layer includes a protrusion that corresponds with the arch support.
4. The insole of claim 1 , wherein the top layer comprises two sublayers of material of different material, and wherein the two sublayers overlap each other within the top layer.
5. The insole of claim 1 , wherein the middle layer is formed as a j-shaped strip.
6. The insole of claim 5 , wherein the j-shaped strip further includes a second straight portion adjacent to the curved portion and wherein the second straight portion extends along a medial edge of the insole to a terminal end of the second straight portion, the medial edge of the insole corresponds to a medial edge of a wearer's foot, and wherein the second straight portion does not extend a substantial distance along the medial edge of the insole.
7. The insole of claim 6 , wherein the insole further includes an arch support.
8. The insole of claim 7 , wherein the second straight portion does not extend past the arch support.
9. The insole of claim 1 , wherein the bottom layer further comprises a rigid plate coupled to the base.
10. The insole of claim 9 , wherein the rigid plate is configured to fit within a cavity of the middle layer formed between the straight portion and the curved portion.
11. The insole of claim 1 , wherein the straight portion of the middle layer provides a rearfoot posting.
12. The insole of claim 1 , wherein the curved portion is configured to provide a cupping effect to the wearer's heel.
13. The insole of claim 1 , wherein the top layer extends a first length and the middle layer extends a second length, wherein the first length is longer than the second length.
14. A high-heel women's shoe, comprising
an insole comprising a top layer, a middle layer, and a bottom layer, wherein the middle layer is formed as a j-shaped strip and comprises a first straight portion forming a first terminal end of the j-shaped strip, a curved portion adjacent to the first straight portion, and a second portion adjacent to the curved portion forming a second terminal end of the j-shaped strip, wherein the first straight portion is positioned along an edge of the insole that corresponds to the lateral edge of a wearer's foot and the curved portion is positioned adjacent the back of the insole that corresponds to a wearer's heel, and the second portion is positioned along an edge of the insole that corresponds to the medial edge of a wearer's foot, a length from the curved portion to the second terminal end being shorter than a length from the curved portion to the first terminal end, and wherein the insole comprise an arch support;
an outsole configured to permanently receive the insole within the shoe; and
wherein the middle layer is configured to provide a lateral rearfoot posting,
wherein the insole is a non-removable insole permanently fixed in the high-heel women's shoe.
15. The shoe of claim 14 , wherein the shoe further includes a cushioning layer positioned on top of the top layer.
16. The shoe of claim 15 , wherein the cushioning layer includes a first cushion segment and a second cushion segment.
17. The shoe of claim 16 , wherein the first cushion segment is positioned to be below the wearer's arch and the second cushion segment is positioned to be below the plantar aspect of the wearer's foot, sparing the arch.
18. The shoe of claim 16 , wherein a gap is formed between the first and second cushion segments.
19. The shoe of claim 16 , wherein shoe further includes a wrap that partially covers a portion of the first cushion segment.
20. The shoe of claim 14 , wherein the first terminal end and the second terminal end of the j-shaped strip each taper to a relatively thin edge compared to a thickness along the first straight portion and second portion.
21. The shoe of claim 14 , wherein the first straight portion includes an outer edge that is shaped and sized to conform along a substantial portion of the lateral edge of the wearer's foot.
