  • Patent number: 4747989
    Abstract: Apparatus for producing a corrected mold for a foot having a rear portion and a forefoot portion, includes a resilient cushion which relatively immobilizes the forefoot portion with respect to the rear portion thereof when the foot is supporting its respective portion of full body weight, the resilient cushion having a rear section with a first thickness and a front section with a second, smaller thickness for supporting the foot, wherein the position of the rear portion of the foot on the resilient cushion is adjusted so that the resilient cushion adopts a corrected contour of the foot; knee alignment cups for positioning a knee corresponding to the foot such that the foot is in a substantially neutral position when the foot is positioned on the resilient cushion and the knee is positioned in accurate alignment with the foot; and a molding material positioned between the foot and the resilient cushion for producing the corrected mold once the foot and the knee have been so adjusted.
