Barefoot Running Form

I lifted this graphic from the Long Sox Fitness blog, which I encourage you to check out.  I am not a fitness guru, but this technique seems to be universal across barefoot running sites.  

Red is good - this is where each stride should hit.
Yellow is also good, but as the secondary strike zone.
And for some strange reason, Green is bad.  This is the area that should not hit the ground, or should barely do so without any real weight transference.

It definitely feels silly right now, but in theory, this is the natural way to run...
