We knew that Laird Hamilton was fan of walking and running barefoot, and now there's a new study that further supports its merits. Researchers found the following: ...the collision-free way that barefoot runners\ntypically land is not only comfortable but may also help avoid some\nimpact-related repetitive stress injuries. Kinematic and kinetic\nanalyses show that modern shoes allow runners to land on the heel, as\nthey do when they walk. Runners who don't wear shoes land more often on the ball of the foot or\nwith a flat foot. This means that they often flex their ankles as they\nstrike the ground and generate smaller impact forces than shod,\nrear-foot, strikers — compare the impact generated by landing from a\njump on your heel versus your toes.
