Abstract
A shoe size selection system using a foot image to obtain measurement information in three dimensions leading to a proper shoe size recommendation. The system provides a computer program that interprets three-dimensional information about a foot and calculates the key features that relate foot length and girth data that affect the comfort and fit of a shoe. Apparatus is used to allow the computer to reproduce on a viewing screen the results of a scan of a foot and to indicate on a chart a preferred shoe size for a foot that may be normal as to physical form or abnormal as to physical form.
