I've used Danners, Rockies, Crispi Valdres, Lowa Zephyrs, Solomon GTX 4, and have a pair of Tibets on the way. Out of the box, the Solomons are my favorite, but I did 50ish miles packing last year and the sole almost felt too soft and I could feel the rocks underneath with a heavy load. They also don't last me very long. I liked the Valdres and Lowas, but a good soaking shrank both significantly. The Rockies take forever to break in, and the longevity is hit and miss, but once they are broke in, they are great.
I was looking between the Tibets and Nevadas, but decided to go with something more heavy duty and went with Tibets.
