So my buddy and I decided to do the entire Art Loeb Trail in a day a few months back, and since 310 miles last fall on the AT gave me a pair of collapsed arches (resulting in wearing orthotics), I thought I'd try hiking in my vibram shoes, especially since they're supposed actually strengthen the arch muscles and eventually "cure" my fallen arches problem. It was rough with all the roots/rocks but I could see how, eventually, one could potentially get used to it enough to potentially hike long distances, every day, for an extended period of time. I did complete all 30.1 miles that day, albeit incredibly sore in certain spots which I assumed were muscles used in barefoot walking that aren't engaged in "shoe'd" walking. What do you guys think? I'm effing tired of feeling the little bump from orthotics and think that itself would be enough to get someone off the trail after 800 or so miles. Any thoughts/opinions are greatly appreciated!
