Cool site Darryl. Definitely a good resource. Barefoot running is cool in that it's pretty self regulating, if that's the right term.
If you're running and feel pain, you go slower, and shorter distances. No pain = faster pace and eventually longer distances.
Gray Cook had a good piece on the subject at the end of a strength coach podcast a while back. Basically, that the body will let you know what's okay, and what's not.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
