I keep my shoes on until I reach my room and settle in for the night. I can't stand having bare feet, so I'm still wearing socks even without shoes. And with four animals in the house that like to make messes, I'd rather have some extra protection for my feet in case I step in something unpleasant.
And I'm not fussed about the floors getting dirty because I only have carpet in two rooms in the house. The rest of the rooms are easy-to-clean tile floors because--again--animals.
