Shoe-fitting fluoroscopes, also sold under the names X-ray Shoe Fitter, Pedoscope and Foot-o-scope, were X-ray fluoroscope machines installed in shoe stores from the 1920s until about the 1970s in the United States, Canada, United Kingdom, Australia, South Africa, Germany and Switzerland.[1] In the UK, they were known as Pedoscopes, after the company based in St. Albans that manufactured them.[2] An example can be seen at the Science Museum, London.[3] At the beginning of the 1930s, Bally was the first company to import pedoscopes into Switzerland from the UK. In the second half of the 20th century, growing awareness of radiation hazards and increasingly stringent regulations forced their gradual phasing out. They were widely used particularly when buying shoes for children, whose shoe size continually changed until adulthood.
A shoe-fitting fluoroscope was a metal construction covered in finished wood, approximately 4 feet (1.2 m) high in the shape of short column, with a ledge with an opening through which the standing customer (adult or child) would put their feet and look through a viewing porthole at the top of the fluoroscope down at the X-ray view of the feet and shoes. Two other viewing portholes on either side enabled the parent and a sales assistant to observe the toes being wiggled to show how much room for the toes there was inside the shoe. The bones of the feet were clearly visible, as was the outline of the shoe, including the stitching around the edges.
