By far the least comfortable of the 10+ Vasque boots I have owned (outside of the terrible redesign of the once-wonderful Breeze GTX-- the II was the best light hiker ever, the III is definately not). The Snowblime is very stiff out of the box, and though I am trying to break them in, two weeks later they are still stiff and rubbing the outside of both big toes badly- and I bought a size up (14) from my regular 13 just in case. But the worst part is they are not as warm as one would expect from a boot that is promised to "take on winter's worst."  I didn't expect to the 200 gram Thinsulate to keep me warm in Antarctica, but I DID expect them to work well in mild Oregon winters. They do not. On a recent day of around 36 degrees, dry conditions, and moderate activity my toes were cold all day- and I was wearing thick winter socks as well. I hope others have better results with this boot, but as a long-time loyal Vasque-only buyer I am disappointed and on the verge of returning these.
