  • Apparatus, system and method for forming custom-made shoe inserts
    Patent number: 5640779
    Abstract: A foot impression unit is provided with an array of gauging elements, a control mechanism for urging the gauging elements into contact with the undersurface of a person's foot to form an impression of the undersurface of the foot, a locking mechanism for releasably locking the gauging elements in place to retain that impression, and a sensing mechanism for scanning the gauging elements to produce digital signals indicative of the positions of the gauging elements. These digital signals are stored and processed by a computer to provide a stored data record serving as a digital representation of the impression of the undersurface of the foot. The computer may also be employed to provide stored additional information for modifying that data record to compensate for a perceived defect of the foot.
