Abstract: A device in the form of a parallelogram for use with an inclinometer for measuring angle of a height differential between two points of a surface such as the angle of heel to forefoot height differential of a shoe.

Abstract: A shoe is tailored for a foot of a person by positioning the foot in a range of incremental heel to forefoot height differential positions, altering the sole of the shoe to have a heel to forefoot height differential which match one of the heel to forefoot height differentials which is determined for the foot to be optimum for mobility and/or flexion and/or balance, and forming an insole for the shoe which conforms to the altered sole. A device in the form of a parallelogram for use with an inclinometer for measuring the angle of heel to forefoot height differential of a shoe.

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 engaged to the heel end portion and the ski respectively engage each other in a manner to provide height adjustability of the heel end of the boot. A track on either of the boot or the ski is slidably engaged by the respective member. One of the members has an inclined serrated surface which engages a serrated surface of the other member for adjusting height. Alternatively, one of the members has an inclined surface, and height adjustment is achieved by a threaded rotatable member on one of the members which threadedly engages longitudinally spaced indents or other formations in the other member.

Abstract: A mechanism for attaching a boot to a ski with the heel end of the boot being height adjustable. The boot comprises a footboard having a heel to forefoot height differential which matches a heel to forefoot height differential of a respective foot of the person wearing the boot when determined to be optimum as the foot is positioned incrementally in heel to forefoot height differential positions and compared for mobility and/or flexion and/or balance. The boot cuff is height adjustable relative to the boot shell.

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.
