Abstract

A padded shoe, comprising a flexible, resilient sole having a substantially smooth surface; a shoe upper, wherein at least a portion of the shoe upper has padding; an ankle padding structure extending from the shoe upper, adapted to cover the medial malleolus of a wearer; a padded tongue; a means to retain the shoe on the foot of a wearer; an outer protective flap, the outer protective flap being located such that the outer protective flap covers at least a portion of the retaining structure; and an engagement structure for securing the outer protective flap to the shoe upper, the engagement structure being located such that the outer protective flap substantially covers the engagement structure, whereby 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, the engagement structure, or the wearer'"'"'s ankle.

Claims

1. A padded shoe, comprising:

a flexible, resilient sole having a substantially smooth surface;

a shoe upper adjoined to the sole, wherein at least a portion of the shoe upper has padding disposed therein, the shoe upper defining a vamp having a throat and a quarter having an ankle collar top line;

an ankle padding structure extending from the shoe upper, the ankle padding structure being adapted such that the ankle padding structure at least partially covers the medial malleolus of a wearer and does not cover the lateral malleolus;

a padded tongue attached to the shoe upper;

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

an outer protective flap attached to the shoe upper, the outer protective flap being located such that the outer protective flap covers at least a portion of the retaining structure; and

an engagement structure for securing the outer protective flap to the shoe upper, the engagement structure being located at least partially under the outer protective flap such that the outer protective flap substantially covers the engagement structure,

whereby the wearer can strike a target with the shoe, and the target and the wearer are protected from injury caused by direct impact with at least one of the retaining structure, the engagement structure, and the wearer'"'"'s medial malleolus.

2. The padded shoe of claim 1, the flexible sole further comprising a split sole, wherein the split sole comprises a separate forefoot sole portion under the front portion of the shoe upper and a separate rearfoot sole portion under the heel portion of the shoe upper.

3. The padded shoe of claim 1, wherein the outer protective flap is padded.

4. The padded shoe of claim 1, wherein the outer protective flap is attached to the shoe upper at one side of the outer protective flap.

5. The padded shoe of claim 1, wherein the padded tongue portion has closed-cell foam padding disposed therein.

6. The padded shoe of claim 3, wherein the outer protective flap has closed-cell foam padding disposed therein.

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

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

9. The padded shoe of claim 1, wherein the retaining structure is disposed between the padded tongue portion and the outer protective flap.

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

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

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

13. The padded shoe of claim 1, wherein the padding in the shoe upper is closed-cell foam having 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.

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

15. The padded shoe of claim 1, wherein the padding in the shoe upper has a thickness between approximately 0.125 inch and approximately 3.0 inch.

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

17. The padded shoe of claim 16, wherein the surface pattern further comprises a plurality of grooves disposed on a lower surface of the sole, whereby the plurality of grooves operate to increase flexibility of the sole.

18. The padded shoe of claim 17, wherein the plurality of grooves are arranged to allow a flexing of the sole to generally match a natural flexing of a wearer'"'"'s foot.

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

20. The padded shoe of claim 19, wherein the chamfering provides a smooth arcuate edge to the sole.

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

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

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

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

25. The padded shoe of claim 1, wherein the shoe upper is entirely padded.
