The purpose of this study was to make low-cost and custom-made 3D printed insoles for flat-foot people and to investigate the feasibility of these insoles in walking and running. Thirty people (15 normal and 15 flat-foot people) participated in this study. 3D scanner, 3D printer, and CAD software were used to produce insoles and motion capturing system and a force plate were used to perform gait analysis. Results indicated that custom-made 3D printed insoles were not effective on joint angles and ground reaction forces, but they affected the trajectory of COP positively during stance phase. Further study with different filling rate and materials of insoles are required to generalize 3D printed insoles for flatfoot people.
