Are Your Feet Glowing Or Just Happy To See Me?

1931--Recently, I read about a interesting gimmick to sell shoes. At Cantwell Shoe Company, at no charge, you could have your feet X-rayed to determine a proper shoe fit. The pro's at Cantwell could view your foot's glowing bone structure and take the guesswork out of proper fit.

Having a shoe salesman x-ray customers feet doesn't sound like a good idea, but it would explain why swimming at night might have been a popular pastime.
