We control our posture by using in-shoe insole. However, The effect of different heights of arch support in-shoe insole on foot and lower extremity is unclear. The aim of this study is to examine the relationship between heights of arch support in-shoe insole and foot posture and muscle activity of lower extremity. 10 middle foot arch type males were recruited for this study. Foot kinematic variables, plantar force and muscle activity of lower extremity (Gastrocnemius medialis (GM), Tibialis anterior (TA) and Flexor hallucis longus (FHL)) were collected during static standing, walking and running on a treadmill inserting 3 types of foot arch support insole (low, mid, high) or not inserting insole, respectively. The results show that there were no significant effect on planar force, ankle supi-pronation angle range of motion and muscle activity of lower extremity. In conclusion, there was no large effect of different heights of arch support in-shoe insole on plantar force, foot kinematics and muscle activity of lower extremity.
