These slippers are very comfortable. They have great support. I asked around as to what size to order if I normally wear a 10.5. I was told not to order the 9.5 to 10.5 size but to go up a size. So glad I didn't listen! The 9.5 to 10.5 fits perfectly. Very happy.Wait. Two days later, they became incredibly loose and kept falling off! Returned.
