I ordered the size 7 and they fit perfectly. I purchased a size up so that she can grow into them. If it begins to degrade, I will make sure to update my review, but I have very high hopes! I usually wear a size 9 but in all Fitflops I order an 8. This rise block provides three different height positions, which I have found beneficial for helping to make my bike a little more comfortable. They are very stiff so the arch doesnt collapse (which I actually like). Wer einen schönen Sommerschuh sucht, ist hier sehr gut bedient! Overall it fits well but the only thing I find uncomfortable is the top part which touches the top of my feet. This works but it isnt that great. It was clear to see that the box had been open at one time and then taped closed.
