Joe, I'm with you on the Pronghorn's. I bought a pair for an elk hunt last year. They really are one of the most comfortable boots I've ever had, but I wasn't very confident in the soles. We had some nasty weather, in some really rugged terrain, and I think I hit the dirt four different times on that trip. Twice was while crossing streams on wet slippery rocks, so maybe any boot would have tossed me, but I blamed the soles.
When it gets really rugged and steep, I like something with a more aggressive tread. This year I bought a pair of Meindl hikers and they did great for me.
I still have the Pronghorns, and will definately use them again in less severe situations.
