The mechanics of foot scanning

Reporting on how SATRA’s major data collection project was undertaken.

The need to understand foot size and shape is not a new concept, and SATRA has performed a significant number of foot dimension surveys periodically since its establishment in 1919. These surveys were paramount in the creation of the precision grade last in the 1940s, which was recognised as a significant improvement against previous systems. Large quantities of shoes were manufactured in the new grade, which quickly became an industry standard. Since then, SATRA has produced numerous articles to assist the footwear industry with fitting and grading guidelines. SATRA has now completed and published a major reference work called Global Foot Dimensions, and this article describes the technical aspects of how it was achieved.
