I'm surprised at how many people wear shoes inside. We are a no shoes house. To me shoes are dirty and I don't want dirt and germs tracked all over my house when my kids play on the floor. I think about where those shoes have been (public washrooms) and what they have stepped on/in and I cringe at the thought if them in mjy house. We have mostly carpet though.

At other people's houses I alwas take my shoes off even if the owner says not to.......unless the floor was cold tile and covered in dog hair, then I might reconsider.
