Abstract
Abstract A footwear of the present invention is provided with tank chambers which are disposed to be in contact with an instep, sole and ankle of the user for applying pressure thereto to protect his foot from shocks. The tank chambers are filled with air and air pressure within the tank chambers can be adjusted. The footwear is further provided with a pressure sensor for measuring air pressure within the tank chambers to generate a pressure signal, and a pressure data displaying device 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 an indication on the pressure data display device.
