Yeah we are definitely not a country that takes it black and white. Did you walk through mud, snow, ice? Take it off, please. Your sweat is less of an issue than turning the floor into a dirt rally. But it also depends on the rules of the house. Someone who has carpet is going to ask you to take them off, while someone with an easily cleaned hardwood or plastic floor might not bother. Some people have shoe-proof ground floors, while going upstairs is entering the more private part of the house where shoes aren’t welcome.

Just ask, and you will find out. And at home, you’re the boss!
