I bought a pair of these for my wife after she slipped in her sheepskin slippers who’s sole had worn shiny. She’s been delighted with them. I bought her a size 5, her normal shoe size and they fit well but she always wears 2 pairs of socks. I then ordered some for myself. I’m normally a size 8, but reading that they were often on the large side I ordered a 7.5. They were way way too big. I sent them back and ordered a size 6. Oh too small! Finally ordered a 6.5 which fits fine! Bit of a Cinderella story but I am really happy with them. They are warm snug comfortable and I feel very safe on polished floors.
