The tank chambers (5B) are filled with air and air pressure within the tank chambers can be adjusted. The footwear is further provided with a pressure sensor for measurings air pressure within the tank chambers to generate a pressure signal, and a pressure data displaying device (7) for indicating pressure data on the basis of the pressure signal generated by the pressure sensor. Therefore, the user can make sure on the pressure data display device a pressure level at which the most suitable pressure for his foot is obtained. The user is also allowed to extremely easily adjust the air pressure at the above pressure level, watching indication on the pressure data display device.
