Abstract

Improved shoe inserts (22, 56, 63) are provided which are designed for placement within the toe regions (37, 52, 64) of shoes (34, 50, 62) to provide enhanced comfort to the shoe wearers. The inserts (22, 56, 63) are preferably cut from initial pillow-shaped bodies (20) to give the custom-designed inserts (22, 56, 63). The inserts (22, 56, 63) are designed to substantially occupy the distal end of the shoe toe region and present a proximal toe-engaging face that substantially spans the cross-sectional dimension of the toe-region. The inserts (22, 56, 63) are preferably formed of heat-sensitive, viscoelastic, polyurethane foam material.

Claims

1. A method of increasing the comfort of a shoe during wearing thereof, wherein the shoe presents a substantially closed toe region having a cross-sectional dimension, said method comprising the steps of:

(a) providing a shoe insert body formed of compressible material,

said body presenting a substantially rectangular plan configuration,

said body having a generally bulbous mid-section with lower and upper surfaces that are generally arcuate,

said body being severable along a generally diagonal cut line from a first corner to an opposing second corner to present two insert bodies,

wherein each said insert body is adapted to be placed within said toe region of said shoe;

(b) severing the body along said cut line to obtain said two insert bodies,

wherein each said insert body includes a proximal toe-engaging face dimensioned to substantially span the cross-sectional dimension of the toe region;

(c) placing one of said insert bodies within the toe region of the shoe, with the toe-engaging face directed proximally; and

(d) donning the shoe so that at least some of the toes of the wearer come into contact with the toe-engaging face and compress the insert body.

2. The method as claimed in claim 1, wherein the proximal toe-engaging face is a substantially flat surface corresponding to the diagonal cut line for engagement by said at least some of the toes of said wearer of the shoe.

3. The method as claimed in claim 2, wherein each insert body further presents a corner apex positioned opposite the proximal toe-engaging face and adapted to be placed in the forward-most area of said toe region.

4. The method as claimed in claim 3, wherein said cross-sectional dimension of said toe region tapers distally.

5. The method as claimed in claim 4, wherein each said insert body has opposite upper and lower surfaces and opposite sides, with the surfaces and sides tapering distally from the toe-engaging face.

6. The method as claimed in claim 1, wherein said body is a generally quadrate shape with a tapered outer margin.

7. The method as claimed in claim 1,

step (a) including the step of forming the compressible material of heat-sensitive, viscoelastic polyurethane.

8. The method as claimed in claim 1, further including—

(e) resizing each said insert body as the wearer'"'"'s foot grows.

9. The method as claimed in claim 8,

step (e) including the step of trimming each said insert body to a new, smaller-sized insert body.

10. The method as claimed in claim 9,

step (e) including the step of removing a proximal portion of each said insert body, such that a new, proximal toe-engaging face is defined after the proximal portion has been removed.

11. A method of increasing the comfort of a shoe during wearing thereof, wherein the shoe presents a substantially closed toe region having a cross-sectional dimension, said method comprising the steps of:

(a) providing a shoe insert body formed of compressible material,

said body presenting a substantially rectangular plan configuration,

said body having a generally bulbous mid-section with lower and upper surfaces that are generally arcuate,

said body being severable along a generally bisectional cut line from a first side to an opposing second side to present two insert bodies,

wherein each said insert body is adapted to be placed within said toe region of said shoe;

(b) severing the body along said cut line to obtain said two insert bodies,

wherein each said insert body includes a proximal toe-engaging face dimensioned to generally span the cross-sectional dimension of the toe region;

(c) placing one of said insert bodies within the toe region of the shoe, with the toe-engaging face directed proximally; and

(d) donning the shoe so that at least some of the toes of the wearer come into contact with the toe-engaging face and compress the insert body.

12. The method as claimed in claim 11, wherein said body is a generally quadrate shape with a tapered outer margin.

13. The method as claimed in claim 12, wherein the quadrate body presents a width and a length, and the length is greater than the width.

14. The method as claimed in claim 13, wherein the bisectional cut line is across the width of the quadrate body.

15. The method as claimed in claim 13, wherein the bisectional cut line is across a diagonal of the quadrate body.

16. The method as claimed in claim 15, wherein each insert body further presents a corner apex positioned opposite the proximal toe-engaging face and adapted to be placed in the forward-most area of said toe region.

17. The method as claimed in claim 13, wherein each said insert body has opposite upper and lower surfaces and opposite sides, with the surfaces and sides tapering distally from the toe-engaging face.

18. The method as claimed in claim 11, wherein the proximal toe-engaging face is a substantially flat surface corresponding to the bisectional cut line for engagement by said at least some of the toes of said wearer of the shoe.

19. The method as claimed in claim 11, further including—

(e) resizing each said insert body as the wearer'"'"'s foot grows.

20. The method as claimed in claim 19,

step (e) including the step of removing a proximal portion of each said insert body, such that a new, proximal toe-engaging face is defined after the proximal portion has been removed.
