There has been considerable interest recently in altering running technique to reduce impact loads and loading rates in the belief that this might reduce injury rates. There was a recent study I previously wrote about and now there is this one : Impact reduction through long-term intervention in recreational runners: midfoot strike pattern versus low-drop/low-heel height footwear Marlène Giandolini, Nicolas Horvais, Yohann Farges, Pierre Samozino, Jean-Benoît Morin European Journal of Applied Physiology April 2013 Impact reduction has become a factor of interest in the prevention of running-related injuries such as stress fractures. Currently, the midfoot strike pattern (MFS) is thought as a potential way to decrease impact
