ABSTRACT:
A custom molded insole for supporting the human foot in a ski boot or other footwear is disclosed. The insole is a one-piece, thin, contoured blank of semi-rigid, bendable, resilient material molded to include the complete detail of the full plantar surface of a foot. The insole provides a four-point contact with a supporting surface or ski boot at the heel, great toe, and at least two spaced metatarsal heads to provide natural balance and proper dynamic positioning of the foot and immediate energy transfer between the foot and various footwear such as a boot/ski when skiing.
Also disclosed is the method for making the custom insole including forming a negative impression of the plantar surface in an impression retaining material by pressing the foot into the material while bearing at least a portion of the body weight on that foot with the impression material firmly supported on a rigid surface. A heated blank of the resilient material is then formed in the impression, preferably using the same foot to press the blank down into the impression.
Also disclosed is a kit for forming the custom insole including at least one piece of impression material and at least one blank of semi-rigid, bendable, resilient material.
