I got a size larger and the sole barely fit. The calf area doesn't button up at all, very very tight.

They are beautiful boots, very comfortable to walk in, very lightweight and well made. The only drawback is that they are narrow for wider calves. So if you don't have slim legs (like luckily I don't), you might prefer something else. If I had tried them on in a store, I probably wouldn't have bought them due to the fit.
