I wonder if you and/or others might be confusing the x-ray machines with the mechanical foot measuring machines. I'm middle aged and remember Clarks (probably in Sheffield, UK) having what looked like a crushing machine with steel plates that closed - very gently - on to the feet and gave a read out of size and width. (See image at https://www.bbc.co.uk/news/business-32738088#_=_ https://www.bbc.co.uk/news/business-32738088#_=_ under "Appropriate measures", left hand machine seems familiar to me). I remember it being a very strange but pleasant experience and wonder now if it wasn't my first ASMR.
