Abstract

Abstract The invention relates to footwear. The invention has for its purpose to design footwear of different types, such as walking shoes, boots, sport shoes and the like in such a way that the footwear dependent upon the situation and, if desired, controlled by the user, can produce signals that can be perceived by other persons. As an example reference is made to the use of sport shoes by a sportsman in twilight or darkness. In this situation it may be important, if his sport shoes e.g. at the rear side, can produce light that may have a varying position and/or intensity. Also an acoustic signalling is possible. In order to realize the above purpose the invention provides footwear which is characterized by electrically energizable signal means, and a source for electric energy for powering said signal means.
