Schnees boots out of Montana sells the same boot (I think) as the "Sheep Hunter". I bought a pair a few years ago for a Dalls sheep hunt in the Brooks range, Alaska.
This a a great boot! After several days of scrambling around in rocks, scree, slogging through mud, etc........ the boots cleaned up no worse for the experience. Others in the camp with Danner Pronghorns, Vasque and other leather/cordura type hiking boot came back to base with boots that looked as though they had been run through a shredder.
The boots are tough and comfotable, but they are stiff when new and require significant breakin. I wore mine almost every day for 3 month before my sheep hunt. The boot is also heavy. If you are hunting less extream terrain, I would suggest a lighter weight boot such as the Pronghorn. I have a pair of those as well and they were very comfortable from the first moment I put them on. However, if you are going to be hunting very rugged terrain that requires good ankle support and is tough enough to take out whatever you throw at them........the Lowa's can't be beat.
PS, I ordered mine from Schnees and they advised me to order 1/2 size larger than normal as the boots were sized small. I did, and they fit fine.
