Just felt wrong on my feet; too big at an 8.5. I wear an 8.5-9....surprised they were too big. I didn't order a smaller size since they felt totally flat. Ok, they are a water shoe but reading a few other reviews, I thought they may have a bit more 'substance' to them. I will give them a 3 star rating since they are a water shoe; and are pretty. I should have expected them to not be what they 'look like'....more substantial!
