Anyway, KenBob stresses that it is not enough to have minimal shoes - barefoot means barefoot. Proprioception - the sense of your body's position in space - is driven by the feet and shoes blunt that sense.
The same idea popped up in the Becoming Bulletproof book that I mentioned last week.
Then I saw this excellent piece from mc Mick Wilkinson Part I: Why Barefoot Running (in shoes) Is not barefoot running
It is an excellent piece and I am looking forward to the rest of the series.
