Thanks for sharing. This fascinates me. I sooo want to run barefoot, but every time I try, no matter how brief the distance and how perfect my stride, something goes wrong. I step on a camouflaged rock and bruise my foot (just days before a race). I land funny and **something** begins to ache in the ball of my foot...for weeks. For now, I'm devotedly practicing POSE technique, which has helped tremendously. Maybe someday I'll ditch my orthotics, then buy a pair of VFFs. For now, I keep hunting for tidbits that will eliminate my last traces of skepticism.
