Every running shoe has a function of preventing injuries, primarily achieved by its stability and shock-absorbing characteristics. These characteristics have been evaluated mainly in the respects of motion analysis and sole-material analysis, up to now. In addition, EMG analysis can be considered essential since muscular overuse is known to cause such injuries. This paper describes the relationship between shoe's stability and kinematics and EMG activity of lower extremity. Experiments employing 5 experiences runners revealed that activity of tibialis anterior could be effective for evaluating pronation, and activities of both fibularis longus and gastrocnemius would probably be useful for evaluating kinematics of the foot in the kicking phase.
