Thanks to all the reviews, I knew to go up a half size which fits perfectly.  I probably could have gone up a whole size, but I am super happy withthe 1/2 size.  I normally wear an 8.5 wide, and bought these in a 9.  These feel like they were made just for my feet.  I LOVE them!!  The have plenty of support but have a pillowy cushion that cradles your feet.  These are the most comforatble sandals I have ever worn. Love the color too!
