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 also includes a retention strap, a first one-way tensioning device, and a second one-way tensioning device. The first one-way tensioning device is coupled to the first side of the outer shell, and 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 second one-way tensioning device is coupled to the second side of the outer shell, and 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 retention strap;
a pad having a flexible portion configured to extend from the pad and couple the pad to the retention strap, the flexible portion being offset from a center of the pad;
a first one-way tensioning device coupled to the first side of the outer shell, the first one-way tensioning device being configured to allow movement of the retention strap in a first direction and to restrain movement of the retention strap opposite the first direction; and
a second one-way tensioning device coupled to the second side of the outer shell, the second one-way tensioning device being configured to allow movement of the retention strap in a second direction and to restrain movement of the retention strap opposite the second direction.

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

3. The boot of claim 2 , wherein the first cam buckle has a release lever that projects outward from the first cam buckle when the first cam buckle maintains the position of the retention strap.

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

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

6. The boot of claim 1 , wherein the first one-way tensioning device defines a gap that admits a portion of the retention 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 retention strap, the release mechanism being located inferior to the gap.

7. The boot of claim 1 , wherein the retention strap comprises a first portion and a second portion that are formed of a fabric mesh or webbing, and the retention strap comprises a buckle configured to join the first portion and the second portion; and
wherein the first portion of the retention strap has an end that forms a first loop of the fabric mesh or webbing, and the second portion of the retention strap has an end that forms a second loop of the fabric mesh or webbing.

8. 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; 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.

9. The boot of claim 1 , wherein the flexible portion of the pad is configured to capture the retention strap within the flexible portion by extending around the retention strap, and wherein the flexible portion of the pad is movable along the retention strap when the flexible portion extends around the retention strap.

10. The boot of claim 1 , wherein the flexible portion extends around the retention strap to capture the pad to the retention strap such that the pad is slidable along the retention strap.

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

12. The boot of claim 1 , further comprising:
a sole pad coupled to the outer shell;
a calf pad coupled to the outer shell; and
a padded liner configured to wrap around a patient's foot and leg, the padded liner being removable from the outer shell.

13. A boot comprising:
an outer shell having a first side and a second side located opposite the first side;
a retention strap;
a first one-way tensioning device coupled to the first side of the outer shell, the first one-way tensioning device being configured to allow movement of the retention strap in a first direction and to restrain movement of the retention strap opposite the first direction; and
a second one-way tensioning device coupled to the second side of the outer shell, the second one-way tensioning device being configured to allow movement of the retention strap in a second direction and to restrain movement of the retention strap opposite the second direction;
wherein the first one-way tensioning device has a release mechanism that is configured to allow tension in the retention strap to be reduced in response to pressure on the release mechanism that is directed toward the first side of the outer shell to which the first one-way tensioning device is coupled.

14. The boot of claim 13 , wherein the first one-way tensioning device comprises a cleat or clamp.

15. The boot of claim 13 , wherein the first one-way tensioning device comprises a first cam buckle, and the second one-way tensioning device comprises a second cam buckle.

16. The boot of claim 13 , wherein the first side of the outer shell defines an opening through the outer shell to an interior of the boot, and the retention strap extends through the opening; and
wherein the first one-way tensioning device is coupled to the first side of the outer shell at the opening, and the retention strap extends from the opening through the first one-way tensioning device.

17. The boot of claim 13 , wherein the retention strap comprises a first portion and a second portion that is detachable from the first portion, wherein the retention strap comprises a buckle configured to attach the first portion and the second portion.

18. The boot of claim 13 , further comprising:
a heel strap having a first portion and a second portion, the first portion of the heel strap being looped around the first portion of the retention strap and the second portion of the heel strap being looped around the second portion of the retention strap; and
a heel pad attached to the heel strap, the heel pad being located to cushion a heel of the patient when a foot of the patient is located in the boot;
wherein the heel strap is configured such that advancing the retention strap through the cam buckle tightens the heel strap.

19. The boot of claim 13 , wherein the first one-way tensioning device is configured to allow movement of the retention strap in the first direction and restrain movement of the retention strap opposite the first direction without manipulation of the first one-way tensioning device by a user.
