I bought these boots in this winter and I tried it on some 2000-3500m mountains.
I think it is very comfortable to wear and to get on.
Temperature... in -20°C - -25°C, above 3000m I felt my legs cold. It was cold with 2 socks especially when I wore crampons.
I think I will use something warmer inside and it will be OK.
I have been testing my boots for half a year. I used them for several times in 2000-3000m mountains. I don't know why the tongue of the boots broke in my shin-bone. I wore 2 pairs of long socks and these were absolutelly not crinkled. But from other hand I took part in more tours where I didn't have any problems. These kept my legs very warm and dry for -20°C although my feets are often very cold in leather boots.
