This study aimed to investigate the biomechanical variations among different types of footarches. Plantar pressure and foot bone stress of three arch types under bipedal standing, singlefoot standing and running mid-stance were investigated by simulation. Compared with the nor-mal foot, the stress in the hind foot area of high arch foot increased significantly, while the con-tact area of the low arch foot increased. Bone stress in high arch increased more significantlywhen changed from bipedal standing to single foot standing or running. The results supportthe link between abnormal arches and foot pain, providing design basis for orthopedic insoles.
