Abstract

A method, system, apparatus, and/or device for supporting a plantar flexion ridge. The method, system, apparatus, and/or device may include a leg calf shell further with a leg calf shell plantar flexion ridge at a lowermost point. The method, system, apparatus, and/or device may include a boot shell connected to a bottom portion of the leg calf shell. The boot shell may include a boot shell plantar flexion ridge at an uppermost point or the boot shell. The boot shell plantar flexion ridge may contact the leg calf shell plantar flexion ridge at a plantar flexion ridges region. The method, system, apparatus, and/or device may include a posterior stretch cord assembly. The first end of the posterior stretch cord assembly may attach to a back of the leg calf shell and the second end of the posterior stretch cord assembly may be attached to a back of the boot shell.

Claims (40)

1. A system, comprising:

a leg calf shell further comprising a leg calf shell plantar flexion ridge at a lowermost point;

a boot shell rotatably connected to a bottom portion of the leg calf shell, wherein the boot shell comprises a boot shell plantar flexion ridge at an upper portion of the boot shell, wherein the boot shell plantar flexion ridge contacts the leg calf shell plantar flexion ridge at a plantar flexion ridges region and rotates no further; and

a strap configured to connect a side of the leg calf shell to the boot shell, wherein the strap comprises:

a first ring;

a first connector attached to a bottom portion of the first ring;

a second ring;

a second connector connected to a bottom portion of the second ring;

a non-stretch cord configured in a loop with a first portion of the loop connecting to the first connector and a second portion of the loop connecting to the second connector;

a hollow sheath positioned on a portion of the strap to be coaxial to the portion of the strap;

a first cover attached to the first connector and a first end of the hollow sheath to cover a first end of the hollow sheath and at least a portion of the first connector; and

a second cover attached to the second connector and a second end of the hollow sheath to cover a second end of the hollow sheath and at least a portion of the second connector.

2. The system of claim 1 , further comprising a c-clip configured to fit over the hollow sheath, the first cover, or the second cover, wherein the c-clip is adapted to provide additional strength and structural integrity to the strap.

3. The system of claim 1 , wherein:

the first ring is configured to connect to a back portion of the leg calf shell; and

the second ring is configured to connect to a back portion of the boot shell.

4. A device, comprising:

a leg calf shell further comprising a leg calf shell plantar flexion ridge at a lower portion;

a boot shell rotatably connected to a bottom portion of the leg calf shell, wherein the boot shell comprises a boot shell plantar flexion ridge at an upper portion of the boot shell, wherein the boot shell plantar flexion ridge contacts the leg calf shell plantar flexion ridge at a plantar flexion ridges region; and

a strap configured to connect a side of the leg calf shell to the boot shell, wherein the strap comprises:

a first buckle;

a first connector attached to a bottom portion of the first buckle;

a second buckle;

a second connector connected to a bottom portion of the second buckle;

a cord configured in a loop with a first portion of the loop connecting to the first connector and a second portion of the loop connecting to the second connector;

a hollow sheath positioned coaxial to the cord;

a first cover attached to the first connector and a first end of the hollow sheath to cover a first end of the hollow sheath and at least a portion of the first connector; and

a second cover attached to the second connector and a second end of the hollow sheath to cover a second end of the hollow sheath and at least a portion of the second connector.

5. An apparatus, comprising:

a first fastener;

a first connector attached to a bottom portion of the first fastener;

a second fastener;

a second connector connected to a bottom portion of the second fastener;

a cord configured in a loop with a first portion of the loop connecting to the first connector and a second portion of the loop connecting to the second connector;

a hollow sheath positioned coaxial to the cord;

a first cover attached to the first connector and a first end of the hollow sheath to cover a first end of the hollow sheath and at least a portion of the first connector; and

a second cover attached to the second connector and a second end of the hollow sheath to cover a second end of the hollow sheath and at least a portion of the second connector.

6. The apparatus of claim 5 , wherein:

the first fastener is at least one of a first buckle, a first loop, a first ring, a first clasp, or a first clip; and

the second fastener is at least one of a second buckle, a second loop, a second ring, a second clasp, or a second clip.
