System and method for forming custom insoles for use in footwear

A method of forming a custom fitted shoe insole, the method comprising:

• heating a shoe insole template plate to a predetermined temperature sufficient to deform the heated shoe insole template plate;
• placing the heated shoe insole template plate onto a foam structure retained inside an angled rectangular housing having opposed rigid side walls, wherein said housing has a trapezium shaped side profile,
• wherein said housing is filled with said foam structure and the foam structure conforms to the shape of said housing, such that the shape of the foam structure side profile matches the trapezium shaped side profile of the housing,
• wherein a top edge of the opposing side walls of said housing slopes down from a higher end of said housing to an opposing lower end of said housing,
• wherein the angled rectangular housing comprises a rectangular lip with an arcuate cutout, said lip extends from the higher end of said housing along a short segment of said sidewalls and covers a portion of said foam structure,
• wherein the arcuate cutout is configured to receive a heel portion of the heated shoe insole template,
• wherein the foam structure slopes downward from the upper end of said housing to the opposing lower end of said housing,
• wherein the housing is strong enough to support a body weight of a user standing with a foot on the foam structure, wherein the rigid side walls limit lateral expansion of the foam structure when the foam structure is deformed in response to pressure applied by the user's foot;
• placing the user's foot on the heated shoe insole template overlying the foam structure such that the user's heel is proximate the upper end of said housing and their toes are proximate the opposing lower end of said housing, wherein the user's foot slopes downward from the upper end to the opposing lower end;
• applying downward pressure to the heated shoe insole template via the user's foot, causing the heated shoe insole template to deform and form a topology that matches a bottom of the user's foot;
• and
• cooling the shoe insole template so as to harden it with the matching topology, thus forming the custom fitted shoe insole.
