No slippers. I don't like things on my feet.
But, I used to have an adorable pair of those bunny slippers, you know the ones with the super long ears and whiskers and such. I wore those till they were ratty and then I grew out of the footwear thing.
The human foot is designed to go bare, as with the rest of the animal populace. We run better, walk better, and have less issues if we don't wear shoes. One of the many reasons I was so grateful to be able to work from home, no shoes.
I finally got my husband off the "you look sexy in heels" thing when I showed him pictures of actresses feet after years of wearing designer heels. They have the gnarliest looking feet I've ever seen. At the time he joked that he may never get hard again.
