I have seen in Switzerland that people leave their shoes at the entrance and switch to house shoes. Or they use a shoe cover when they enter house with shoes. Probably because houses are mostly wooden floored.
So shoes on is not universal in the West.
Most of the west outside of the US takes shoes off or swaps 'em for indoor shoes.
Between "Most of the west" and "Asian countries" it seems like it's the vast majority of industrialized countries that take off or swap their shoes inside. There's just an odd blip of over-represented online people who don't.
I'd like to see a citation for "most of the west".
Just not for emergency services!
