Abstract

A shoe having an upper portion with a slit opening, through which an insert is placed or placeable into the shoe upper between its upper material and the lining portion, specifically intended for the purpose of rehabilitation, which shoe is designed such that it can be better adapted to various types of foot shapes.

The shoe is intended to enable the plaster cast or other support cast, normally necessary in the healing process and employed for foot injuries or foot surgery, to be removed after a short time. This is achieved in preferred embodiments through use of at least one insert 6 of flexible material that has a plate-like configuration. At least one side of insert 6, and a facing inner surface of the shoe upper material coming into contact therewith, has a surface which provides that, at least between these two inner surfaces coming into contact, there is sufficient friction to cause insert 6 to be retained in place during the wearing of the shoe.

Claims

1. A shoe for the physical protection of a foot during medical rehabilitation thereof having an upper portoin with at least one slit opening, through which an insert is placeable into a space that is located between material of which the upper portion is formed and a lining for said upper portion, and at least one insert of compressible material that is conformable to the shape of the foot by compression of the insert and that is of a plate-like configuration;

wherein at least one side of the insert and a respective inner shoe surface contacting said at least one side have means for producing sufficient frictional contact therebetween to prevent displacement of the insert relative to the inner shoe surface while the shoe is worn.

2. Shoe according to claim 1, wherein an insert is placed in an ankle area and has an at least partially circular cut-out.

3. Shoe according to claim 2, wherein the insert is outwardly tapered at an edge of a side facing the foot.

4. Shoe according to claim 1, wherein the insert is outwardly tapered at an edge of a side facing the foot.

5. Shoe according to claim 4, wherein a foot-facing side of the insert is smooth.

6. Shoe according to claim 5, wherein at least one inner surface of the shoe upper material consists of an open pored synthetic foam material.

7. Shoe according to claim 1, wherein a foot-facing side of the insert is smooth.

8. Shoe according to claim 1, wherein said insert is formed of a material having synthetic elastomeric properties.

9. Shoe according to claim 8, wherein said insert is formed of a microporous rubber.

10. Shoe according to claim 8, wherein said at least one side of the insert is provided with a fabric having a rough outer surface.

11. Shoe according to claim 10, wherein said fabric consists of a polyamide.

12. Shoe according to claim 1, wherein said at least one slit opening extends along an upper edge of the shoe upper.

13. Shoe according to claim 12, wherein said at least one slit opening is a pair of lateral slit openings.

14. Shoe according to claim 12, wherein fastening means for closing the at least one slip opening is provided.

15. Sheo according to claim 14, wherein said fastening means is a zipper closure.

16. Shoe according to claim 1, wherein the means for producing frictional contact comprises a roughened surface on at least an inner surface of the shoe upper material and a roughened surface on at least a facing surface of the at least one insert.

17. Shoe according to claim 1, wherein said space has an area that is substantially larger than said at least one insert for enabling selective insertion of one or more inserts of various shapes and sizes.

18. A shoe having an upper portion with at least one slit opening, through which an insert is placeable into the shoe upper, particularly for rehabilitation purposes, and at least one insert of flexible material and plate-like configuration;

wherein at least one side of the insert and a respective inner shoe surface contacting said at least one side have means for producing sufficient frictional contact therebetween to prevent displacement of the insert relative to the inner shoe surface while the shoe is worn, wherein at least one inner surface of shoe upper material consists of an open pored synthetic foam material.

19. Shoe according to claim 18, wherein said insert consists of a material having synthetic elastomeric properties.

20. Shoe according to claim 19, wherein said insert is formed of a microporous rubber.

21. Shoe according to claim 19, wherein the slit opening extends vertically along a back seam at the heel of the shoe.

22. Shoe according to claim 19, wherein said at least one slit opening extends along an upper edge of the shoe upper.

23. Shoe according to claim 22, wherein said at least one slit opening is a pair of lateral slit openings.

24. Shoe according to claim 22, wherein fastening means for closing the at least one slit opening is provided.

25. Shoe according to claim 24, wherein said fastening means is a zipper closure.

26. A shoe having an upper portion with at least one slit opening, through which an insert is placeable into the shoe upper, particularly for rehabilitation purposes, and at least one insert of flexible material and plate-like configuration;

wherein at least one side of the insert and a respective inner shoe surface contacting said at least one side have means for producing sufficient frictional contact therebetween to prevent displacement of the insert relative to the inner shoe surface while the shoe is worn, wherein the slit opening extends vertically along a back seam at the heel of the shoe.
