@quixoticgeek Shoes. My floors aren't great, and usually I have a few dogs which make socks or barefoot very...fuzzy. Shoes are vastly easier, and I don't have to take the time to remove and add footwear every time I need to go out to the detached garage or to check the mail.

If I've got a day where I'm staying inside all day (inclement weather, I'm sick, whatever) I'll opt for slippers, but they have soles on them. The fluffy slippers are a bad idea for the aforementioned reasons.
