From the 1920s through roughly the 1970s, shoe stores in the United States, Britain, Canada, Australia, South Africa, Germany, and Switzerland marketed the shoe-fitting fluoroscope as a scientific guarantee of elegance and comfort. A child—or adult—stood on a platform, inserted both feet into an opening, and peered through a viewing port while X-rays revealed the bones, toes, and outline of the shoe. Parents and sales assistants watched through additional ports as the customer wiggled their toes, turning a potentially dangerous medical technology into an entertaining retail spectacle. The machines were especially popular for fitting children's shoes, even though children are substantially more radiosensitive than adults. Radiation surveys later found enormous variation between models: American machines averaged about 13 roentgen to the feet during a typical 20-second exposure, while one machine delivered approximately 116 roentgen in the same interval; shielding could be displaced, weakened, or poorly maintained, allowing radiation to scatter toward customers and employees. Sales staff faced repeated occupational exposure, with some American monitoring showing pelvis-level dose rates as high as 95 milliroentgens per week. Three shoe salespersons were later identified with rare conditions that might have been connected to chronic exposure, including a severe radiation burn requiring amputation in 1950, ulcerating dermatitis in 1957, and basal-cell carcinoma of the sole reported in 2004. Scientific evaluations in 1948 also found the devices ineffective for their supposed shoe-fitting purpose, but retail representatives publicly minimized the danger and argued that the machines prevented injuries from badly fitted footwear. As knowledge of radiation-induced harm expanded after the late 1940s, regulators increasingly discouraged their use, and the devices gradually disappeared.

The X-Ray Shoe Fitter: A Retail Fashion Gadget That Irradiated Children and Sales Staff
