I know this is not the fault of the seller but this slipper sock was far too narrow for my ankle and foot. I was very disappointed with this product because it had no elasticity + it was not even close to being wide enough  to even get on my ankle and foot. BTW -- although I have a size 12-13 foot; the width is only medium and I am not Bigfoot. If you are looking for a comfortable slipper sock; this is not it. Stay away from Acorn brand. The Acorn brand deserves 1 star but I gave this product an extra star beccause I am awaiting my refund from Amazon for this cheaply made slipper sock.---- EDIT -- To add insult to injury; Amazon witheld $ 3.99 from my refund to pay for return shipping for these Slipper Socks which were incorrectly advertised at Amazon as being true to size
