It has been common practice in studies of running shoe cushioning to use the magnitude of the initial transient peak (Fz 1 ) of the vertical ground reaction force (Fz(t)), as an index of heel impact severity. Frequently, the results of such studies have been inconsistent with impact attenuation theo...
