Knot- It's mentioned big-time in chi-running, isn't it?
Mimi- I had read that- re: rickshaw pilots. man. pounding feet on cobblestone or packed dirt day in and day out. you'd think... but you're right. Another study that I can't find right now documented natives' feet and foot structures- adults who'd never worn shoes etc. The 'lines' for their big toes were actually straight from heel to the tip of their toes. I know mine point inward a bit... and I was a barefoot kid. Can't stand tight shoes to this day... I liked your nike frees. I was actually really looking at the vibram fivefingers... they're forming quite the following in the running circles. 4mm thick vibram soles, polyamide uppers and individual toes. 'interesting' looking, to be sure, but yes, in a land of broken glass, dog poop and bottlecaps, I'm really interested.
