Taking your shoes off indoors is just so obvious a custom in Finland that nobody seems to question it at all. ‘Why would you keep your shoes indoors?’ asks Riitta, 29, an Oulu teacher. ‘It’s disgusting. I think that we Finns like to keep our houses clean.’
‘I wouldn’t wear my shoes in house,’ comments Katariina, 29, also a teacher. ‘And I definitely wouldn’t wear them in somebody else’s house. I never really thought about it. But you don’t want to bring dirt from outside inside.’
This article has some interesting discussion about how old the custom of removing shoes in Finnish homes is.
