ABSTRACT:
A bladder usable in the sole of a shoe for supporting the plantar area includes a plurality of chambers designed to provide a resilient resistance force. In the fabrication of the bladder, each of the chambers is formed in fluid communication with each other, and fluid is supplied into the chambers at a selected location. After the chambers have been pressurized to the desired internal pressure, the fluid communication port(s) is sealed. Although certain of the chambers are pressurized to the same internal pressure, different resistance forces are provided by forming the chambers with different volumes.
