This shoe was not comfortable due to the very stiff and sructured way the toebox area leads upwards toward the rise of the heel. There is really no room for the foot to move, and I don't think sizing up would help or I would have, because they're very cute. The angle might be fine for a high heel, but in the boot, it feels kind of like you're about to break your ankle or toes or both off, at all times. I don't wear heels very often, and this heel isn't very high, but the toe area was just not "workable" for me. They are very attractive boots, though, and if you are used to your foot being jammed up like that, you might be fine! I couldn't even sit down with them on comfortably, let alone walk around.
