Sandals size 39 / 8 fits like 7 or 7.5

Sandals size 39 / 8 USA but fits like a 7 or maybe 7.5 but def not an 8. My foot hangs off the back just a lil and I wear an 8. I don't like my foot to be hanging on the back too much like with these shoes otherwise I would keep them bec I love them. They are so cute just a tiny bit too small. Brand new never worn.
