I use two different pairs of boots depending on what I'm doing, but one of them is the Zamberlan Vioz asked about in the OP. I really like them so far, although I've only got about 50 miles on them to this point. They're wider in the toe box than most boots are, and that was a big deal to me. The comfort is incredible, and I've put them through some pretty vigorous water proofedness tests. I even used them with snowshoes and crampons for some outings this winter, and they were great.
My other pair is the Asolo Fugitives, and they're also nice. A bit lighter, I tend to wear them when it's hotter out.
