I have been wearing a size 7 in shoes for almost 10 years, so i went with my gut and ordered a 7 in these. They fit well, and they're not so much of a heel to toe height difference that they're hard to walk in, but they are STIFF. The tops rub against my ankle bone and caused it to tear my tights.
But i get a ton of compliments when I wear them, lol.
But i would stick to just using these as costume shoes, not normal shoes.
