I have the same boots in black in a size 40 and really wanted them in brown- could only find a 39, so I thought I'd give it a shot. They're just too snug. They're a European 39 and I'd say they're between an 8.5or a 9 US size. I don't have a box. just trying to recoup some money so I can buy a larger pair I found on eBay. They're gorgeous boots! The brown is such a great caramel- brown color you don't see often! The distressing is also very cool. Overall the boots are in great shape!
