Barefootrunnning, Forefoot or heellanding?

Found on Youtube. A video comparing, side by side, running on barefoot and on shoes.

I would say a great add fore barefootrunning.

Better still, the findings from a more scientific appraoch to the subject:

TITEL: The Effect of Running Shoes on Lower Extremity Joint Torques
link to the full article

Objective: To determine the effect of modern-day running shoes on lower extremity joint torques during running.

Results: Increased joint torques at the hip, knee, and ankle were observed with running shoes compared with running barefoot. Disproportionately large increases were observed in the hip internal rotation torque and in the knee flexion and knee varus torques. An average 54% increase in the hip internal rotation torque, a 36% increase in knee flexion torque, and a 38% increase in knee varus torque were measured when running in running shoes compared with barefoot.

Conclusions: The findings at the knee suggest relatively greater pressures at anatomical sites that are typically more prone to knee osteoarthritis, the medial and patellofemoral compartments. It is important to note the limitations of these findings and of current 3-dimensional gait analysis in general, that only resultant joint torques were assessed. It is unknown to what extent actual joint contact forces could be affected by compliance that a shoe might provide, a potentially valuable design characteristic that may offset the observed increases in joint torques.

I am almost sorry it is to cold outside a the moment to go running barefoot (there is snow and a freezing wind with a chillfactor bringing down the temp to minus 12 dergrees centigrade)
