I have been wearing these for decades and used to be able to get them in local stores.  - give me so much comfort when i arrive home - i wear an 8 shoe size but have a slim foot so I need to buy the medium- it fits fine.  - i own three pairs  - two at home (one for my daughter if she stops by) and i keep one pair in my carryon suitcase to bring to hotels and on airplanes. i love that they can be washed in the machine.  i really do not like the current trend in slippers with so much foam in the base - they are too bouncy and make me loose my balance. Wow - i sound like an old lady - but i am not - i am hip - i am a rock n roll fan and go to lots of concerts! lol
