It is illegal to use an X-ray shoe-fitting machine.

The Law

In the 1940s and 50s, shoe stores utilized fluoroscopes—devices that blasted X-rays through customers' feet so they could see the bones inside their new shoes. As the dangers of extreme radiation exposure became obvious, Maine banned these novelty machines to stop businesses from giving their customers cancer in the name of a perfect fit. The ban was a crucial step in early consumer radiation protection.
