I love these slippers, they are very comfortable and have a good grippy, sturdy sole, they are also water resistant so you can wear them to pop outside if need be. I would say to be wary of the sizing, as I normally take a size eight (7 1/2 Clarkes shoes) and bought the Medium size (8-9), Initially these were very snug, but after a couple of weeks are just perfect. If you are a large 9 or 10, I think you will need the large size.
