I am a tried and true size 6 in shoes. It is extremely rare that a size 6 doesn't fit me. That being said, I initially ordered a size 6. I tried to make the 6 work, but after a few nights of wearing around the house and re-adjusting the bands several times I could never get it where my heel didn't sit too close to the back edge. The toes had room up front. So I returned and ordered a size 7 which was entirely too large all around. I then decided to go try a few other styles on in-store and had the same issue. Sadly it looks like this sandal won't work for me unless they come out with half sizes.
