The control system is comprised of a CPU, pressure sensors and valves. The control system is used to control fluid communication between the chambers to dynamically adjust the pressure in the cushioning chambers for various conditions such as the activity that the footwear is used in, the weight of the individual and the individual's running style. The footwear can adjust the sole according to the need of the user.

US 5918381 A pertains a Shoe sole with liquid-powered ventilating fans. The sole of a shoe enables the feet of a user to cool and dehumidify, providing superior comfort to the feet of the person wearing the shoe. The sole comprises two layers, one of which has a liquid-filled area with a liquid powered turbine and the other layer containing a built-in air fan or fans or other turbines, which are powered by the liquid turbine responding to the liquid movement in the outer layer. These two layers are molded or otherwise connected to a shoe sole. The mechanical or magnetic gearing of all the turbines is configured to control the direction of air movement.

US 6134812 A discloses a shoe sole that makes it possible for the forces which are exerted when the foot is placed on the ground to be utilized for aiding the walking action of the user. A first cavity in the heel region with an intermediate pressure- storage space in the ball-of-the-foot region, and a further, third cavity in a space between the sole, the space being located between the ball-of-the-foot region and heel region. A line with a valve connects the second and third cavity, and a line with a valve connects the third and fourth cavities. Line and blocking mechanism connect the third cavity to the outside air and/or the shoe interior. A line and a valve connect the first cavity to the outside air. An outsole is provided beneath the sole.
