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 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 that is adapted to cover the medial malleolus of a wearer; a padded tongue and other components. The sole may be formed from a material having a shore durometer reading between about 40 and about 60 such that the shoe is lightweight yet provides appropriate support.

Claims

1. A padded shoe, comprising:

a flexible, resilient sole having a substantially smooth surface, wherein the sole is formed from a material having a shore durometer reading between about 40 and about 60;

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;

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 padded tongue; 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,

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 medial malleolus.

2. The padded shoe of claim 1, where 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, 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.

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

5. 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.

6. The padded shoe of claim 5, wherein the outer protective flap is formed from dual outer protective flaps.

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

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 padding in the shoe upper is closed-cell foam having a durometer of approximately 0.253.

10. 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.

11. 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.

12. 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.

13. 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.

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

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

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

17. A padded shoe, comprising:

a flexible, resilient sole having a substantially smooth surface, wherein the sole is formed from a material having a shore durometer reading between about 40 and about 60;

wherein the sole is a split sole comprising 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;

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 dual outer protective flap attached to the shoe upper, the dual outer protective flap being located such that the outer protective flap covers at least a portion of the padded tongue; and

an engagement structure for securing the dual outer protective flap to the shoe upper, the engagement structure being located at least partially under the outer protective flap such that the dual 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 medial malleolus.

18. The padded shoe of claim 17, where the sole is formed from a material having a shore durometer reading between about 40 and about 50.

19. The padded shoe of claim 17, wherein the padding in the shoe upper is closed-cell foam having a shore durometer of approximately 0.253.

20. The padded shoe of claim 17, 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 and 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.
