ABSTRACT:
A footbed support for footwear comprises a laminate footbed custom formed to the shape of the wearer's foot from laminae of water-activated, polyurethane-impregnated fabric sheet material. The footbed is formed by placing the water-activated lamina on a resilient domed foot pad, then placing the foot in a predetermined position on the pad over the laminae so that the longitudinal arch of the foot overlies a portion of the dome corresponding to the height of the longitudinal arch and shape of the sole of the foot. The foot is then weighted to form an impression in the laminate, and the laminate allowed to partially cure before the foot is removed. Before final placement of the foot on the pad, the laminae are cut to differential lengths and widths if desired to provide a desired differential flexibility, rigidity, and thickness in different areas of the cured laminate footbed. An apparatus for forming the footbed includes a tray divided into two laterally separable sections, each containing a domed section of the resilient foot pad. Each of the pad sections is indexed by color-coded zones on the domed portion and by index pointers as an aid to foot positioning according to preliminary foot classification.
