Abstract: A process for measuring a person's foot to determine the optimum surface for said foot to rest upon to have the optimum balance and range of motion, and the method to transfer these needs to the foot orthotics and footwear. A foot measuring device to use with this process to measure the optimum position and also provide an accurate surface upon which to create the mold for the foot orthotic. An angle measuring device to accurately measure the foot's needs and the surface in footwear that the foot rests upon. A device to alter foam casting blocks used for making impressions of the foot for foot orthotics.

Abstract: A mechanism for attaching a boot to a ski with the heel end of the boot being height adjustable. The toe end portion of the boot is pivotly attaching to the ski. A pair of members extend from the heel end portion and the ski respectively and have serrated surfaces which face each other with serrations in one surface engaging complementary serrations in the other surface at various heights of the heel end portion. The members are fastened together at various heights to which the heel end portion is adjusted. A track on the heel end portion is slidably engaged by the heel end portion member. Alternatively, a pair of members are pivotly attached to the ski along a common pivot axis and are drawn together and apart by a screw, and a track structure on the boot is slidably engaged by end portions of the members. A boot plate is pivotly laterally adjustable. An extension member is attachable to an end portion of the boot plate for increasing boot plate length.
