  • Method and Apparatus for Analyzing Foot Arch Deterioration
    Publication number: 20130296740
    Abstract: A method and apparatus for helping corrective footwear professionals determine a need for corrective footwear comprises using an electronic scanner to determine a first area of the sole of the foot in contact with the scanning equipment within an area of interest and a second area of the sole of the foot not in contact with the scanning equipment within an area of interest. The percentage of the first area to the sum of the first and second areas is used to calculate a pronation/stability index. The pronation/stability index may be used by the corrective footwear professionals to determine the need for corrective footwear.
