Abstract

A padded shoe, such as a kicking boot, is disclosed that is lightweight and padded for use in mixed martial arts and other related activities. The padded shoe may be formed from a flexible, resilient sole; a shoe upper adjoined to the sole, wherein at least a portion of the shoe upper has padding disposed therein; a padded tongue attached to the shoe upper; an outer protective flap attached to the shoe upper; and an engagement structure for securing the outer protective flap to the shoe upper, the engagement structure being located substantially under the outer protective flap such that the outer protective flap 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 at least one of the engagement structure and the wearer'"'"'s instep.

Claims

1. A padded shoe, comprising:

a flexible, resilient sole;

a shoe upper adjoined to the sole, wherein at least a portion of the shoe upper has padding disposed therein;

a padded tongue attached to the shoe upper;

an outer protective flap attached to the shoe upper, wherein at least a portion of the flap has padding disposed therein; and

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

wherein 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 engagement structure and the wearer'"'"'s instep.

2. The padded shoe of claim 1, wherein the sole is formed from a material having a shore durometer reading, between about 40 and about 50.

3. The padded shoe of claim 1, wherein the sole comprises 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.

4. The padded shoe of claim 1, wherein the outer protective flap is attached to the shoe upper at one side of a vamp throat defined in the shoe upper and extends across the vamp throat.

5. The padded shoe of claim 1, wherein the outer protective flap is attached to the shoe upper at an end of a vamp throat defined in the shoe upper and extends longitudinally over the vamp throat.

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

7. The padded shoe of claim 1, wherein the outer protective flap has closed-cell foam padding disposed therein.

8. The padded shoe of claim 1, further comprising retaining structure to retain the shoe on the foot of a wearer, the retaining structure being positioned between the padded tongue and the outer protective flap such that the retaining structure is substantially covered by the outer protective flap.

9. The padded shoe of claim 8, wherein the retaining structure comprises a lacing structure or an elastic material extending across a vamp throat defined in the shoe upper.

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

11. 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.

12. 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.

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

14. The padded shoe of claim 1, wherein at least a portion of the sole has a surface pattern having a plurality of grooves disposed on a lower surface of the sole, whereby the plurality of grooves operate to increase flexibility of the sole and are arranged to allow a flexing of the sole to generally match a natural flexing of a wearer'"'"'s foot.

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

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

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

18. The padded shoe of claim 1, further comprising 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.

19. The padded shoe of claim 1, wherein the padded tongue has a greater thickness of padding material than the padding material disposed in the outer protective flap.

20. The padded shoe of claim 19, wherein the padding in the padded tongue has a thickness between approximately 0.25 inch and approximately 1 inch and wherein the padding disposed in the outer protective flap has a thickness of approximately 0.125 inch.
