Born To Run

Your foot’s centerpiece is the arch […] The beauty of any arch is the way it gets stronger under stress; the harder you push down, the tighter its parts mesh. No stonemason worth his trowel would ever stick a support under an arch; push up from underneath, and you weaken the whole structure.

Christopher McDougall, Born To Run, p126

What kind of stonemason are you? Free your feet! :)
