Please read carefully! 🙂 These are marked as USA 8.5 / Euro 40. They appear to be about a half size smaller. I typically wear an 8.5 and my heel was slightly over the edge of the shoe. Hence, I listed them as a size 8. They are new and never worn (no tags). I tried them on for fit and can say they are incredibly comfortable. Smoke free but not pet free home.
