When I was a lad, shoe stores had fluoroscopes that would show you your feet inside your shoes. It was cool. Only problem was the salesman would put his feet to show you (actually your mom) what a proper fit looked like. So while I got my feet x-rayed once every year or so, the salesman would get his feet x-rayed many times a day. Salesmen ended up getting cancer from it. Doubt if many customers did. I imagine the kid should be ok.
I remember those. I was very nearsighted, and no one had noticed it yet. So when I got up there I couldn’t see nada. Probably avoided a lot of foot zaps. I wondered why all the other kids were so fascinated. I didn’t know it myself! It wasn’t until 3rd grade when a teacher noticed I was copying the cap R on the blackboard like an upside-down U (they used R for “remainder” when teaching division) that someone caught on.
Nowadays I think they are more vigilant, because I see little kids with glasses on.
Oh yeah. I used to to do that. More than the salesman wanted too!
I remember that too, and yeah the show salesman I remember died too. While my mom and sisters were talking with the sales guy I was off in the corner checking out my x-ray feet....a lot more than once. Not too much later we were all surprised when the skin on the bottom of my feet peeled right off. Luckily for me only the outer layer!
I remember those shoe fluoroscopes. They even had an operating one in the local science museum after they had vanished from shoe stores.
