A method of manufacturing a foot auxiliary equipment includes the following steps. Firstly, a foot appearance of a foot and a foot muscle of the foot are scanned for obtaining a foot appearance data model and a foot muscle data s model respectively. Then, the foot appearance data model and the foot muscle data model are synthesized into a foot data model. Then, a dynamic state analysis and a static state analysis are performed on the foot data model. Then, a foot auxiliary equipment data model is generated according to result of the dynamic state analysis and result of the static state analysis. Then, a foot auxiliary equipment is printed by using three-dimensional printing technique according to the foot auxiliary equipment data model.
