Modern xray machines deliver low enough radiation doses that they could probably be used for this reasonably safely. They are routinely used in medical settings after all, but I suspect it would still be a liability nightmare.
But there's no real need to see the bones for fitting shoes. There's plenty of 3D scanning technologies today that do not involve ionizing radiation and would probably be more useful for fitting shoes anyway.
