I read all the previous reviews and here's what I found. They do run big with no half sizes. I am an 8 and 1/2, so I got the 8. They are a little big without socks but wearable. As far as quality, they are fine. They look adorable on and are well made.
I wear a 5.5 normally and bought these in a size 5. I have to wear them with socks and they still have a bit of space. I have very narrow feet so that is the main issue. But they are gorgeous and so well made. I've since bought 2 more pairs from this brand!
