I typically never have issues with shoe sizing but these are insane. I went down a half size and honestly could have gone down another half size. I just decided to wear thick socks with it, but they keep falling down to the point where it's more comfortable to wear without. The issue with these shoes is there is no tongue separate from the rest of the shoe, so you don't really have anything to pull up on, which is odd. My foot tends to slip out the back because the sole is stiff and the leather doesn't move when you arch your foot. Nevertheless, they're incredibly cute and actually quite comfortable (minus the foot slipping part). Definitely going to keep them, break them in and wear them often!
