I'll get my one negative out of the way first and say that, for the price, these boots seem a little 'flimsy.' They are leather and nicely made, but they feel very light and not super sturdy. However they are super cute, so you know.
I usually buy a 7.5 in shoes and go with an 8 in boots, but as these are not a thick sock kind of boot I got the 7.5. They feel noticeably narrow and are quite dainty, not clunky at all. I wore them all night, standing up, last night, and they were comfy enough.
