I think the x-ray machines can now be made much more sensitive so the dose could be vastly smaller. That said, it's a bit unnerving when someone tells you something is save and then goes and hides behind a lead lined booth - even for me as someone who understands the stats around it.

I do think it's in general a good idea to use such tools for better fits, shoes tend to focused more on narrow feet which is possibly a side effect of the shoes themselves. I have to stick to certain brands that cater towards wide feet. Perhaps in the future 3D printed shoes will be good enough that I can swap out my regular shoes for hyper-customized ones.
