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. 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 and in a range of heel angles, altering the sole of the shoe to have a heel to forefoot height differential and heel angle which match one of the heel to forefoot height differentials and one of the heel angles which are 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 and heel angle of a shoe. A method of marketing shoes comprising placing on sale a line of shoes sized for various heel to forefoot height differentials.
