ABSTRACT:
A method and apparatus for determining the critical foot and shoe-last dimensions and variables is provided. The apparatus includes a surface for a foot to stand on, a mechanism to determine the axis passing through heel centerline, a mechanism to determine the foot or shoe last width measurement, a mechanism to determine the axis passing through center of the foot (or last) width, a mechanism to determine the mid-foot height and a mechanism to determine heel width. Based on the above mentioned mechanisms, the apparatus can determine the required dimensions and the curvature of a person's foot, called the flare angle, and as well as the curvature of a shoe-last so that footwear fitting can be improved.
