Abstract: A custom insole is made up of a plurality of layers of a thermoformable material united together at their interfaces to conform in size and contour to the bottom surface of a foot, the layers comprising at least one strength layer and at least one filler layer united to the strength layer and contoured to conform to the bottom surface of the foot; and an arch flange curves upwardly for a distance to laterally support the bone structure in the arch area of the foot. In the method of making the insole, an unformed blank of thermoformable material is placed on a resilient support portion with the ball portion on a firm surface and, by placing the foot on top of the layers and applying downward pressure, it will cause the heel of the foot to form a depression in the heel portion and the ball portion of the foot to flatten out the layers resting on the firm surface.
