I live in north-central Idaho, which has some of the steepest, ruggedest terrain in the lower 48. I have worked and hunted in Idaho for over 40 years and have checked out most available footwear. I currently wear Arrow moccasins (the Lace boot double sole model) for probably 98% of everything I do, including surveying and elk hunting. This year I went on a bivouac hunt with a 45 lb. pack - wearing my moccasins.
I have found out some interesting things about footwear and the feet. God designed the human foot without a raised heel for a reason. If the foot tendons and muscles are strengthened and conditioned properly, they provide most of the ankle support any one will ever need. I have much better balance and am much less clumsy when wearing the moccasins as opposed to the heavy vibram soled boots I wore for many years (Whites, Danner, Asolo etc.) Actually wearing moccasins forces me to take it slow and easy and feel for footing as I go.
There are definitely times that the limited traction is an issue, but I have discovered that even in treacherous footing the moccasins do pretty well - the trick is to go slow and let the contours of your foot grip where they need to. It is indeed a whole new way of walking/hiking/moving, but it works, and my feet are much healthier as a result.
I used to have plantar fasciatis, shin splints, hip joint pain, lower back pain, bunionettes on my toes. Since I began running in minimalist footwear and wearing flat, no-support moccasins the rest of the time I have none of the above issues.
When it is cold, wet or muddy, I have found some light-weight, flat bottomed overshoes that slip over my moccasins and work very well for both water proofing and traction. I have a pair of Schnees and a pair of Beans hunting shoes that sit in the corner because the moccasins are more comfortable.
This system is certainly not for everybody, but if you have ever had foot problems of any sort, you might give some thought to what I have said. At one point a couple of years ago, I came close to not being able to hardly walk, let alone hike, so I know how important it is to take care of ones feet.
To those who might scoff, I would point out that I began wearing the moccasins somewhat as an experiment, always keeping some heavier, soled footwear at hand "in case". However, the more I wore them, the more I liked them - for everything.
