I am so pleased with these boots! I purchased a size 39 and my feet measure 24.5cm and are mountain-shaped. I have medium-volume feet, as well. I've had such a difficult time finding boots this season and these are a winner. They're very comfortable, with plenty of room for splay. The laces are nice quality, the zipper is very smooth and easy to zip, and the leather seems like nice quality as well. As with most barefoot shoes, these do not require any break in. I also find the soles to be very grippy, which I really appreciate since Iive in the midwest. They are wool lined, but one thing to note is that there is smooth and soft leather at the inside of the heel, which isn't the most comfortable if you are not wearing socks only because you can feel the difference between the wool and leather on your heel. I plan to wear socks with mine, so this won't be a problem. I do think this is worth noting because not all lined boots have this feature. It's a smart design choice because I think the boots will hold up well over time since that part of the inside of the shoes will go through more friction with putting the boots on and taking them off. Overall, highly recommend these boots! I wouldn't change a thing.
