I believe the Chinese measurements are incorrect. The Boots fit about 1/4 of an inch too large and a little too wide. I just put on thicker socks and it was fine but I may regret it later after some use. The heel is really soft and I can see how it could fall off over time. I think Dr. Martens should have sewn it in like they did the front sole. Looks are a 5, for the items listed above I took two stars off. I think if I went a size lower it would be far too tight.
