The boots I bought for Iceland Travel (Winter). They were perfect for muddy and cold Verhältnisse- and yet tight. The only drawback: during extended wear shoes inside are slightly damp, presumably because the GoreTex membrane can not sufficiently convey moisture to the outside through the dense surface. Wonderfully warm and a super Sohle- comparable to hiking boots. But on sheer ice, I recommend extra ice claws. Then you are perfectly equipped. The size turns out rather small, although I have a larger number ordered. So it just fit with extra socks, but then there is not much space. Recommended product with a good price / performance ratio.
