I'm glad I read the other 2 reviews before purchasing these since they are final sale! My usual size is 7 1/2, but I purchased a size 7 based on other's feedback that they run big. I would have sized down one whole size to 6 1/2 but that size was not available, so I gambled. The size 7's will work, as they don't slip off my heel, but they are still somewhat bigger than I would like and I have to tighten the shoestrings more. But I just couldn't pass them up! They are absolutely adorable and I can't wait to wear them! But if you're thinking of buying these, and they have your size 1 full size below what you normally would wear, that would be ideal.
