Oh, I like this thread
I wear socks, with a slipper over that goes inside a pair of crocs. Yeah, I broke down this year and bought crocs for inside the house. Slippers just weren't cutting it, even though I love them, and I can't go around barefoot due to a physical issue.
When I see someone barefoot, I always order them to put something on their feet.
