ABSTRACT:
A shoe sole having a sole plate with a ground-engaging side having inflatable tube elements secured thereto. The shoe sole also includes upstanding lateral support walls that define a chamber or an installation space which is in communication with the tube elements by means of inflation openings. Also disposed in the installation space is a valve housing, a miniature pump, and connecting conduits connecting the pump to the inflation openings. The tube elements are provided along medial and lateral edges of the sole, and in the heel region. In addition, the tube elements are inflatable separately from each other so that it is possible to individually adjust the tread characteristics of a shoe provided with the shoe sole. The tube elements further include a longitudinal partition which divides the interior thereof into two air chambers which communicate with each other through at least one opening in the longitudinal partition. That provides improved tread characteristics and increased rigidity of the tube elements.
