Yeah I can see that ofc, if you don't walk around that much. But then for example people that go shopping a LOT in big cities, clubbing and whatnot, then your shoes will get pretty nasty and sticky most likely. Because in most tv-shows whatever the people have been doing they just go in with their shoes on and have them touch their furniture etc, and yes it's tv, but that's why I made this topic since I have never been to America (although I'd love to), so I just wanna know what the customary procedures and thoughts on shoes in the house really are.
