No I do not wear slippers, I just go in bare feet. My feet have always been very narrow, and going barefoot is supposed to make them wider? idk but now age 75 maybe it has helped, especially since the shoes are made in only medium and wide width now.
As for my favourite slippers, that would be the slipper socks for men that came out in the 1950's, and I was maybe 7 or 8 when my mother and I shopped for a pair of these for my father for Christmas. Those slipper socks with soles were a great innovation of their time, and it was a very big deal!
Here you go this is what they looked like; they were wool. Our only heat in that house was a wood stove, and my father liked these very much as he could step out to the woodshed for more wood without putting on shoes! (Or at least he pretended to like them -- I was SO proud!)
