For me... I take off my shoes and wear slippers in my home. Was taught to do this from my parents and it became a habit for me to do it. Whenever I am at someone's else home then I take off my shoes and just have my socks on.
Where I live in the US, it's not typical to take your shoes off inside. Guests usually keep their shoes on while visiting other people's homes. When I walk through my door, I'm immediately in the carpeted living room and there is nowhere either inside or outside that makes sense to leave your shoes. I put on or take off my shoes in the bedroom, so I wear them through the house. But I don't leave them on unless I'm planning on going back out soon. I will either be barefoot or in slippers when I'm at home depending on how cold or warm it is.
