Abstract

In some implementations, a boot includes an outer shell having a first side and a second side located opposite the first side. The boot may include a retention strap. The boot may include a first one-way tensioning device coupled to the first side of the outer shell, where the first one-way tensioning device is configured to allow movement of the retention strap in a first direction and to restrain movement of the retention strap opposite the first direction. The boot may include a second one-way tensioning device coupled to the second side of the outer shell, where the second one-way tensioning device is configured to allow movement of the retention strap in a second direction and to restrain movement of the retention strap opposite the second direction.

First claim

What is claimed is:

1. A boot comprising:
an outer shell having a first side and a second side located opposite the first side;
a first one-way tensioning device coupled to the first side of the outer shell;
a second one-way tensioning device coupled to the second side of the outer shell; and
a strap comprising (i) a first portion having a first handle, and (ii) a second portion having a second handle;
wherein the first one-way tensioning device is configured to engage the first portion of the strap, wherein the first one-way tensioning device is configured to allow movement of the strap in a first direction and to restrain movement of the strap opposite the first direction; and
wherein the second one-way tensioning device is configured to engage the second portion of the strap, wherein the second one-way tensioning device is configured to allow movement of the strap in a second direction and to restrain movement of the strap opposite the second direction.

2. The boot of claim 1 , further comprising a buckle configured to join the first portion of the strap and the second portion of the strap.

3. The boot of claim 1 , wherein the first handle comprises a first loop of the strap, and the second handle comprises a second loop of the strap.

4. The boot of claim 1 , wherein the first handle and the second handle are located outside the outer shell, the first handle and the second handle being located at opposite sides of the outer shell.

5. The boot of claim 1 , wherein the first portion of the strap extends through a first opening in the first side of the outer shell, and wherein the second portion of the strap extends through a second opening in the second side of the outer shell.

6. The boot of claim 5 , wherein the first portion of the strap extends from the first opening through the first one-way tensioning device to the first handle, and wherein the second portion of the strap extends from the second opening through the second one-way tensioning device to the second handle.

7. The boot of claim 1 , wherein the first one-way tensioning device comprises a first cam buckle, and wherein the second one-way tensioning device comprises a second cam buckle.

8. The boot of claim 1 , wherein the first one-way tensioning device comprises a cleat or clamp.

9. The boot of claim 1 , wherein the first one-way tensioning device has a release mechanism that is configured to allow tension in the strap to be reduced in response to pressure on the release mechanism that is directed toward the boot.

10. The boot of claim 1 , wherein the first one-way tensioning device defines a gap that admits a portion of the strap through the first one-way tensioning device; and
wherein the first one-way tensioning device has a release mechanism that is configured to release the strap, the release mechanism being located inferior to the gap.

11. The boot of claim 1 , wherein the first portion and the second portion are formed of a fabric mesh or webbing; and
wherein the first handle comprises a first loop of the fabric mesh or webbing that is located at an end of the first portion of the strap, and wherein the second handle comprises a second loop of the fabric mesh or webbing that is located at an end of the second portion of the strap.

12. The boot of claim 1 , wherein the outer shell comprises a first handle on the first side, the first one-way tensioning device being located inferior to the first handle of the outer shell; and
wherein the outer shell comprises a second handle of the second side, the second one-way tensioning device being located inferior to the second handle of the outer shell.

13. The boot of claim 1 , wherein the strap is a retention strap, and wherein the boot further comprises:
a heel strap having a first portion and a second portion, wherein the first portion of the heel strap is looped around the first portion of the retention strap, and wherein the second portion of the heel strap is looped around the second portion of the retention strap,
wherein the heel strap is configured such that advancing the retention strap through the first one-way tensioning device tightens the heel strap.

14. A boot comprising:
an outer shell having a first side and a second side located opposite the first side;
a first cam buckle coupled to the first side of the outer shell;
a second cam buckle coupled to the second side of the outer shell; and
a strap comprising (i) a first portion having a first handle, and (ii) a second portion having a second handle;
wherein the first cam buckle is configured to allow movement of the strap in a first direction and to restrain movement of the strap opposite the first direction; and
wherein the second cam buckle is configured to allow movement of the strap in a second direction and to restrain movement of the strap opposite the second direction.

15. The boot of claim 14 , wherein the first handle comprises a first loop of the strap, and the second handle comprises a second loop of the strap.

16. The boot of claim 14 , further comprising a buckle configured to join the first portion of the strap and the second portion of the strap.

17. The boot of claim 16 , wherein the first portion and the second portion are formed of a fabric mesh or webbing; and
wherein the first handle comprises a first loop of the fabric mesh or webbing that is located at an end of the first portion of the strap, and wherein the second handle comprises a second loop of the fabric mesh or webbing that is located at an end of the second portion of the strap.

18. The boot of claim 14 , wherein the first portion of the strap extends through a first opening in the first side of the outer shell, and wherein the second portion of the strap extends through a second opening in the second side of the outer shell.

19. The boot of claim 14 , wherein the strap is a retention strap, and wherein the boot further comprises:
a heel strap having a first portion and a second portion, wherein the first portion of the heel strap is looped around the first portion of the retention strap, and wherein the second portion of the heel strap is looped around the second portion of the retention strap,
wherein the heel strap is configured such that (i) advancing the retention strap through the first cam buckle tightens the heel strap, and (ii) advancing the retention strap through the second cam buckle tightens the heel strap.
