I have used my LL Beans (my favorite hunting boot regardless of the terrain) in Colorado many times. I have had no trouble packing/hunting with them in around Montrose, Mt. Zirkel , Steamboat Spring, and Flat Top area. That said they are no good on the red mountain clay after a storm. I came home and bought a quality pair of air bob sole boots. And just don't like the noise they make.
I would not make that area a first time hunt for them. Wearing them on a mountain is a learning process all about foot placement. The Native Americans hunted that country in moccasins. And I can wear moccasins on hilly country but not on the mountains.
If you find them uncomfortable try another manufactures insole before giving up on them.
I usually hunt in snow with them also, its all about moving slow. I just hate the noise a lug sole creates.
