FIT PERFECT, and very comfortable! Really cushiony and comfy! I had a difficult time getting my foot in the first time, but then it sort of stays in place when you take them off. I really like the added ankle strap support as makes them more comfortable to wear. MY daughter has raved about these for over a year, so, I decided to take a chance. Colors were limited in my size, but I chose the black, gray, white and they are very nice. Really would like a pair in a more neutral navy pattern too!  Fits true to size. I wear an 11 and the 11 Fit perfect!  Did I mention how COMFY they are!??? Like walking on a yoga mat! lol
