Abstract-- This paper proposes the smart shoes system classifying a normal, out-toeing, and in-toeing gait to provide the gait information to
customer. It measures and analyzes the gait posture using the distribution of pressure sensors on the insole. It sends the gait information to the smartphone application using a BLE communication. The experiment was performed to test the accuracy of proposed system. Finally, this paper showed that proposed system can measure the accurate gait posture.
