In order to develop a kinematic/kinetic model of shoe stability, the relationship between the physical property of shoe sole material and the rearfoot movement must be know. To clarify this relationship, the 3D motion of the shank and the rearfoot was measured for the self controlled speed running on the hard and soft surface which imitated the shoes sole. Subjects were 4 volunteers. The 3D joint angles in the Joint Coordinate System were calculated and the differences between the 2 surface conditions were examined. The maximum eversion angle on the soft surface mat was significantly larger than that on the hard surface in all subjects. Two subjects were landing at the rearfoot, others were landing at mid or forefoot. It was found that the maximum abduction angle on the soft surface was significantly larger than the hard surface for mid/fore foot runners. It was speculated that the differences in rearfoot movements were caused by the loading to the calcaneus. The results of plantar pressure distribution during the running supported this speculation.
