In this research, a shoe mounted miniature triaxial force sensors was developed to construct a new technique for the measurement of ground reaction force (GRF) distributions in contact area during running. Five sensor and 14 dummy block devices were mounted to a commercial marathon shoe. The shoe mass is 270.0 g. By using the shoe, distributions of lateral, longitudinal and normal direction force components at 19 local positions were measured by changing sensor arrangement at running speed of 5.5 min/km. The results showed contact periods and time history of GRFs at each position during stance phase was clearly different. It was confirmed that the resultant forces of the GRFs obtained from the sensor shoe gave close agreement with the GRFs obtained from the conventional force plate. Based on the distribution of the traction coefficient, which is calculated from the horizontal force divided by the vertical force, high traction coefficient area were clarified at the time 20 and 80% of stance phase. The distributions of the traction coefficient will imply area to apply structure and material design of the high grip shoe sole to avoid slip-related falls.
