The viscoelasticities of arch support structures was recognized in this study, using the simple foot model with the torsional spring-damper model to apply the human foot arch complex. The arch is deformed during bipedal gait motion. Especially the maximum deformation was observed in midstance to push-off. Then the deformation is controlled by means of arch support elements. The recognizing method was based on the hypotheses that the experimented external arch moment was equal to theoretical internal arch moment. The stiffness of the arch was identified at 4 phases in a gait cycle, (I) heel contact phase, (II) the entire planter contact phase, (III) push off phase, and (IV) swing phase. This study shows three results. (1) The arch elasticity increases in the phase III (n =6, p
