let me start by saying i love these shoes. Here in south Texas we can wear them 9-10 months out of the year. My feet, ankles and knees DO NOT HURT ANYMORE!! But FitFlops sizing issues are really starting to make me angry. You really never know what size you're going to get. This pair I ordered a 9 but they are closer to an 8 in actual size. I compared them to a size 8 1/2 I own and they're even shorter and more narrow...Have  to exchange and hope and pray a 10 will actually be a 9.
