R.P.
Because of my medical condition I have to have something on my feet all the time. When I wear slippers, I forget I'm just wearing slippers and will walk out of the house with just them on. I don't do that when I wear the slipper socks with the tread on the bottom. I can wear them around and still put shoes on over them if needed. Plus the tread on the bottom helps so I don't slip in the kitchen or the bathroom where we have tile.
