My feet are standard with but I bought these same one s for my husband in an 11 and he didn?t think he?d get them on as has very wide feet and 1 foot extra wide due to car crash injury yrs ago and he said he was really surprised! I like the grind because it sound like it?s open back although not and with out the leak . The feel good from the first time you wear them. Beautiful sandals! The flip flop is very tight and its tough on the area between the toes. This works very nicely and isnt too unappealing in the living space. Its ~$100 cheaper and looks exactly like it! Seem fine just had to return it because once it?s mounted that?s the position, there?s no adjusting and you can?t turn it I bought them specifically for tennis so wore them around the house the day before I was scheduled to play. Lost my original charger from Google for a while, finally find one perfectly matches my need.
