We have developed an evaluation system for foot arch types using foot pressure distribution data. Especially, we investigated the relationship between the foot pressure distribution data and three-dimensional morphological foot shape. And we also investigated evaluations of the load deformation characteristics and exercise intervention of the foot arch. As the result, six kinds of morphological foot data were correlated to the foot pressure distribution data significantly. About the foot load change, in the normal and high arch groups, it is assumed that the foot arch was deformed by increased foot arch load. On the other hand, in the flat foot group, it is assumed that foot arch structure was reduced and foot function consequently weakened. About the intervention, foot arch status in the abnormal group improved on intervention, and the foot pressure distribution reflected the foot arch.
