I originally wrote "These slippers are well constructed, look good, sized perfectly.  I wear a 11EEE and these are quite comfortable.  They also have a good crepe sole and unlike soles that are non-slip, I don't stumble if I fail to lift my foot high enough as I am prone to do.  The non-slip soles on carpeting don't work for me."
Shortly after this I had to return these as the soles began separating from the upper.  Amazon got me a replacement pair quickly and I have worn them for about 7 months and the soles on these have started separating.  WOULD NOT BUY AGAIN.
