Abstract

A contoured insole especially advantageous for users with medium to high arches is disclosed. It comprises a generally foot-shaped base extending from a heel end to a toe end, which comprises a top surface and a bottom surface. The bottom surface of the base preferably further comprises two indentations formed integrally therein in a forefoot area and a heel area. A forefoot pad and a heel pad are secured to each of said indentations. Preferably, the base is made from a polyurethane foam. The pads are made from rubber or synthetic rubber. A top sheet is coextensive with and secured to the top surface of the base. The top sheet is generally a fabric which preferably has antimicrobial characteristics. In use, the foot of the wearer, with or without a sock or stocking thereon, rests upon the top sheet in the foot-receiving compartment of a user's shoe.

First claim

We claim:

1. A contoured insole for users having a medium or high foot arch, comprising:
a generally foot-shaped base contoured to define a heel receiving cupped area, a midfoot area, an arch area on a medial side of said base, and a forefoot area, said base having a length extending from a heel end to a toe end, a base top surface and a base bottom surface, said base bottom surface further defining a forefoot pad indentation and a heel pad indentation;
a forefoot pad disposed in said forefoot pad indentation in said forefoot area adjacent said arch area and said midfoot area;
a heel pad disposed in said heel pad indentation;
wherein said base further defines a plurality of longitudinal curvilinear compression indentations extending lengthwise in a longitudinal toe-to-heel direction in said arch area on said base bottom surface on said medial side of said base; and
wherein said base further defines a metatarsal support area integral to said base and located in said midfoot area adjacent said arch area;
and wherein said base is formed from a moldable resilient material.

2. The insole of claim 1 , wherein said forefoot and heel pads are made of rubber or synthetic rubber.

3. The insole of claim 1 , wherein said forefoot and heel pads are made of a neoprene synthetic rubber layer which is a polymer of polychloroprene.

4. The insole of claim 1 , wherein said base comprises a lightweight resilient material which is capable of being molded into the desired shape and which provides the desired support and cushioning.

5. The insole of claim 4 , wherein said material is a polyurethane foam.

6. The insole of claim 1 , further comprising a top sheet having a bottom surface and an upper surface, wherein said bottom surface is secured to said base top surface.

7. The insole of claim 6 , wherein said top sheet is a sheet of fabric.

8. The insole of claim 7 , wherein said fabric is treated with an antimicrobial substance.

9. A contoured insole for users having a medium or high foot arch, comprising:
a generally foot-shaped base contoured to define a heel receiving cupped area, a midfoot area, an arch area on a medial side of said base, and a forefoot area, said base having a length extending from a heel end to a toe end, a base top surface and a base bottom surface;
wherein said base further defines a plurality of longitudinal curvilinear compression indentations extending lengthwise in a longitudinal heel-to-toe direction in said arch area on said base bottom surface of said medial side of said base;
wherein said base further defines a metatarsal support area integral to said base in said midfoot area adjacent said arch area; and
wherein said base is formed from a moldable resilient material that compresses in the arch area more easily than other areas of the insole because of the presence of said longitudinal curvilinear compression indentations extending lengthwise in a heel-to-toe direction in said arch area on the medial side of the base of said insole.

10. The insole of claim 9 , wherein said base comprises an indentation to receive a forefoot cushion.

11. The insole of claim 9 , wherein said base comprises an indentation to receive a heel cushion.

12. The insole of claim 10 , wherein a forefoot cushion is disposed in said forefoot cushion indentation.

13. The insole of claim 11 , wherein a heel cushion is disposed in said heel cushion indentation.

14. The insole of claim 9 , wherein said base comprises a lightweight resilient material which is capable of being molded into the desired shape and which provides the desired support and cushioning.

15. The insole of claim 14 , wherein said material is a polyurethane foam.

16. The insole of claim 9 , further comprising a top sheet having a bottom surface and an upper surface, wherein said bottom surface is secured base top surface.

17. The insole of claim 16 , wherein said top sheet is a sheet of fabric.

18. The insole of claim 17 , wherein said fabric is treated with an antimicrobial substance.

19. A contoured arch support molded into an insole base bottom surface comprising:
a plurality of longitudinal curvilinear compression indentations extending lengthwise in a longitudinal heel-to-toe direction in an arch area on a medial midfoot side of a base bottom surface;
said base and said arch area formed from a moldable resilient material that compresses in the arch area more easily than other areas of the insole because of the presence of said longitudinal curvilinear compression indentations extending lengthwise in a heel to-toe direction and located in said arch area on the medial side of the base bottom surface of said insole.

20. The arch support of claim 19 , wherein said plurality of longitudinal curvilinear indentations in said arch area collapse along said lengthwise indentations to fit a user's shoe providing an accommodating fit to said user.

21. The arch support of claim 19 , wherein said plurality of longitudinal curvilinear indentations in said arch area collapse along said lengthwise indentations in said arch area of said medial midfoot to minimize voids caused by air entrapment.

22. The arch support of claim 19 , wherein said plurality of longitudinal curvilinear indentations in said arch area are positioned on said medial midfoot side of said insole from adjacent a lateral midfoot area to said medial side of said insole.

23. The arch support of claim 19 , wherein said plurality of longitudinal curvilinear indentations extend lengthwise in said arch area positioned lengthwise from a border of a forefoot area and said arch area on said medial midfoot side to a border between a heel area and said arch area on said medial midfoot side.
