Well, I spend around 8 months of the year barefoot. But, I live in Middle Tennessee so I'm not exactly hacking it up & down 10k' mountains.
I researched the heck out of boots for this September's trip to Colorado & after looking long & hard at every & all the available minimalist options, talking to many long-time western hunters, outfitters & climbers, I heeded all their advice:
Minimal shoes are great for hiking & hunting, if you're 100% used to them & have no weaknesses & issues & aren't carrying a ton of meat.
If, however, like me, you have any form of arthritis, plantar fasciitis, weak knees, or you're just not used to it; go with a well fitting, well broken-in, stiff soled boot with excellent ankle support.
It may feel odd if you're used to nothing around your tootsies, but your feet, knees, ankles & back will thank you for it after side-hilling with 70#+ strapped to your back.
I ended up buying a pair of Lowa Tibet GTX.
