I've been using the non GTX mountain boot now for over a year for pretty much all outdoor activities (bushcraft, walking, mountain walking, Search & Rescue, etc) and I love them.
I went for the non GTX, so that they would dry quicker when they got soaked, and allow ne to use them all year around. But to keep my feet dry in wet conditions, I wear the Sealskin socks.
How do I rate them?? They're brilliant.
Would I recommend them? Yes, get a pair, you will not be disappointed (get a good fit, as with any boot).
