The study aimed to clarify the effect of shoes (WS) and tights (BT) with the support function on support leg during running. The subjects, eight female Japanese runners, ran for 1-min periods on a treadmill. Motion, electromyography (EMG), acceleration and angular velocity were recorded. The following results were obtained: 1) there was difference in the pronation angle between support shoes and non-support shoes. 2) There was difference in angle of lower leg in frontal plane between support shoes and non-support shoes. 3) Combination of WS and BT might decrease angle of the foot and shank in frontal plane and stabilize the trunk, but the effect varies depending on subjects
