Abstract

A padded shoe includes a flexible, resilient sole having a substantially outer surface. A shoe upper is adjoined to the sole, the shoe upper having closed-cell foam padding disposed therein. A padded tongue is attached to the shoe upper and includes an inner padded tongue portion and an outer padded tongue portion. Retaining structure retains the shoe on the foot of a wearer. Engagement structure is included for securing the outer padded tongue to cover the inner tongue portion, with the engagement structure located at least partially under the outer padded tongue portion. The outer padded tongue portion substantially covers the engagement structure. The wearer can strike a target with the shoe, and the target and the wearer are protected from injury caused by direct impact with the retaining structure and/or the engagement structure.

Claims

1. A padded shoe, comprising:

a flexible, resilient sole having a substantially smooth outer surface;

a shoe upper adjoined to the sole, wherein at least a portion of said shoe upper has closed-cell foam padding disposed therein;

a padded tongue attached to said shoe upper, wherein said padded tongue comprises an inner padded tongue portion and an outer padded tongue portion;

retaining structure to retain the shoe on the foot of a wearer; and

engagement structure for securing said outer padded tongue to at least partially cover said inner tongue portion, said engagement structure being located at least partially under said outer padded tongue portion such that said outer padded tongue portion substantially covers said engagement structure,

whereby the wearer can strike a target with said shoe, and the target and the wearer are protected from injury caused by direct impact with said retaining structure and/or said engagement structure.

2. The padded shoe of claim 1, wherein the outer padded tongue portion is attached to the shoe upper at one side of said outer padded tongue portion.

3. The padded shoe of claim 2, wherein the outer padded tongue portion is attached to the shoe upper at one side of a vamp throat in said shoe upper.

4. The padded shoe of claim 1, wherein at least one of the outer padded tongue portion and the inner padded tongue portion has closed-cell foam padding disposed therein.

5. The padded shoe of claim 1, wherein said retaining structure is selected from the group consisting of laces and elastic material.

6. The padded shoe of claim 1, wherein said retaining structure comprises elastic material disposed between said inner padded tongue portion and said sole.

7. The padded shoe of claim 1, wherein said retaining structure is disposed between said inner padded tongue portion and said outer padded tongue portion.

8. The padded shoe of claim 1, wherein said retaining structure comprises elastic material disposed between said inner padded tongue portion and said shoe upper.

9. The shoe of claim 1, wherein the shoe upper is completely padded.

10. The shoe of claim 1, wherein the shoe upper comprises padding to generally correspond to at least one location on the foot of the wearer, said location including at least one of the group consisting of the forward dorsal region, the top of the foot, the posterior aspect of the heel, the left and right forward lateral aspects of the foot, and the ankle portion.

11. The shoe of claim 1, wherein the closed-cell foam padding in the shoe upper has a durometer of approximately 0.253.

12. The shoe of claim 1, wherein the closed-cell foam padding in the shoe upper has a density of between approximately 1.5 pcf and approximately 4.5 pcf.

13. The shoe of claim 12, wherein the closed-cell foam padding in the shoe upper has a density of between approximately 1.5 pcf and approximately 3.5 pcf.

14. The shoe of claim 1, wherein the closed-cell foam padding in the shoe upper has a compression strength of between approximately 3 psi and approximately 23 psi at approximately 25% deflection and a compression strength of between approximately 9 psi and approximately 42 psi at approximately 50% deflection.

15. The shoe of claim 14, wherein the closed-cell foam padding in the shoe upper has a compression strength of between approximately 6 psi and approximately 22 psi at approximately 25% deflection and a compression strength of between approximately 12 psi and approximately 34 psi at approximately 50% deflection.

16. The shoe of claim 1, wherein the closed-cell foam padding in the shoe upper has a tensile strength of between approximately 28 psi and approximately 145 psi.

17. The shoe of claim 16, wherein the closed-cell foam padding in the shoe upper has a tensile strength of between approximately 30 psi and approximately 120 psi.

18. The shoe of claim 1, wherein the padding in the shoe upper has a thickness between approximately 0.125 inch and approximately 1.5 inch.

19. The shoe of claim 18, wherein the padding in the shoe upper has a thickness between approximately 0.25 inch and approximately 0.5 inch.

20. The shoe of claim 19, wherein the padding in the shoe upper has a thickness of approximately 0.375 inch.

21. The shoe of claim 1, wherein the sole has a substantially smooth lower surface.

22. The shoe of claim 1, wherein at least a portion of the sole has a surface pattern thereon.

23. The shoe of claim 1, wherein at least a portion of the perimeter of the sole is chamfered.

24. The shoe of claim 23, wherein the chamfering provides a smooth arcuate edge to said sole.

25. The shoe of claim 1, wherein the sole is formed at least partially from EVA.

26. The shoe of claim 1, wherein the sole has a durometer between approximately 0.20 and approximately 0.23.

27. The shoe of claim 1, wherein the engagement structure comprises hook and loop fastener material.

28. The shoe of claim 1, wherein the shoe upper is formed using a Strobel construction.
