1. A custom footbed for a foot, the footbed comprising:
- a substrate comprising an upper surface formed to the contour of only a portion of the plantar surface of the foot, wherein the substrate comprises a uniform layer thickness;
a depression occupying a selected area of the upper surface of the substrate, wherein the upper surface of the substrate deviates from the contour of the plantar surface of the foot within the selected area occupied by the depression, and whereby the depression and the foot define a cavity; and
a compressible wound spacer locate within the depression on the upper surface of the substrate.

Abstract
Custom footbed devices, methods of constructing the devices and kits for constructing custom footbeds are disclosed that may be particularly advantageous in the treatment of plantar ulcers. The devices offer the advantage of off-loading pressure from the plantar ulcers in a device that is easy to construct, reusable, lightweight, and custom-made to improve patient comfort. The footbeds are constructed using a curable substrate that is formed to the plantar surface of the foot except in the areas occupied by spacers designed to off-load wounds on the bottom of the foot.

10. A method of constructing a custom footbed, the method comprising:
-
providing a curable substrate comprising curable material; providing a compressible surface to support the curable substrate; providing a wound spacer; locating the curable substrate between the wound spacer and the compressible surface; positioning the wound spacer at a selected location on the upper surface of the curable substrate between a foot and the substrate; forming the curable substrate to the contour of a portion of the plantar surface of the foot, wherein the curable substrate deviates from the contour of the plantar surface of the foot within the selected location occupied by the wound spacer; and curing the substrate after forming; wherein the curable substrate and the compressible surface extend over the entire length of the foot. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
