Orthotic device for open shoes
View Patent ↗An orthotic device is designed to be reused and reapplied in open shoes include an adhesive layer which securely, but temporarily, bonds the insole to a shoe. In some embodiments, the insole both supports and cushions a foot. In other embodiments, the insole solely cushions the foot. The supporting insoles include an arch support and a heel lift. The cushioning insoles include a flat sole pad, a contoured sole pad, a ball of foot pad and a heel spur pad. In some embodiments, a textile covering is included over the insole.
1. An orthotic supportive device comprising:
a first layer comprising a first thickness and cushion regions having a greater thickness than the first thickness;
a second layer, coupled to the first layer, comprising a semiflexible polymer having greater rigidity than the first layer; and
a third layer, coupled to the second layer, comprising a viscoelastic polymer.
2. The device of claim 1 wherein the first, second, and third layers are translucent.
3. The device of claim 1 wherein a first cushion region of the first layer, positioned at a first position where a base of a heel of a foot will be received by the orthotic device, whereby the first cushion region cushions a calcaneus of the foot.
4. The device of claim 1 wherein a first cushion region of the first layer is positioned at a first position which will receive a medial arch zone of a foot.
5. The device of claim 1 wherein a first cushion region of the first layer is positioned at a first position which will receive a lateral arch zone of a foot.
6. The device of claim 3 wherein a second cushion region of the first layer is positioned around the first position and is U-shaped.
7. The device of claim 3 wherein a second cushion region of the first layer is positioned at a second position which will receive a metatarsal zone of the foot.
8. The device of claim 7 wherein a second cushion region of the first layer is positioned at a third position, forward and lateral of the second position.
9. The device of claim 3 wherein in the second layer at about the first position is a concavity.
10. The device of claim 3 wherein the viscoelastic polymer of the third layer is positioned at about the first second position.
11. The device of claim 3 wherein the second layer comprises first and second thickened regions, on a first and second side of the first position, extending away from the first layer.
12. The device of claim 7 wherein the viscoelastic polymer is not beneath the first and second thickened regions.
13. The device of claim 1 wherein the viscoelastic polymer has an inherent adhesive property.
14. The device of claim 1 wherein the first layer comprises at least six cushion regions.
15. The device of claim 1 wherein a first cushion region has a different thickness from a second cushion region.
16. The device of claim 1 wherein a first cushion region has the same thickness as a second cushion region.
17. An orthotic supportive device comprising:
a first layer comprising a first thickness and cushion regions having a greater thickness than the first thickness;
a second layer, coupled to the first layer, comprising a semiflexible polymer having greater rigidity than the first layer; and
a third layer, coupled to the second layer, comprising a viscoelastic polymer, wherein the viscoelastic polymer has an inherent adhesive property, and the first, second, and third layers are translucent.
18. The device of claim 17 wherein a first of the cushion regions is above the viscoelastic polymer of the third layer.
19. The device of claim 18 wherein a second of the cushion regions is positioned to receive a metatarsal zone of a foot during use of the orthotic device.
