The purpose of this study is to establish models of the first to the fifth ray of the skeletal plantar arch and to analyze the model application in kinematics. Foot models are built through CT scan, then inverse model recreation. We calculated the metatarsal angles and horizontal metatarsal angles using motion analysis system. The first to the fifth metatarsal angle and horizontal metatarsal angle are both different. The same trend happened in the lateral and medial metatarsal angles. These results especially the middle part angle relationship can be further used for analysis of foot mechanics during walking or other activities.
