An article of footwear is provided, particularly a soccer shoe, having one or more sensors mounted in the shoe upper which, when impacted by a ball, are effective to send a signal to a controller representative of the magnitude of the force with which the ball was struck by the shoe. A liquid crystal display, mounted within a housing which also carries the controller, provides a visual indication of the force of the ball strike which can be readily observed by the wearer of the shoe.
