In this study, we developed a new type of high performance shoes by making use of an embedded technology in order to realize a stable walking for elderly person. Since the shoes have soft rubber elements, pressure sensors, valves and compressors, the shoes can measure pressure change of each element in an insole. That is to say, we can estimate trajectory of gravity position of the foot by calculation of pressure values in elements. Further, the effectiveness of the proposed insole that indicates a difference between an ideal walking trajectory and an inherent walking trajectory of a subject is cleared through some experimental results.
