ABSTRACT:
Shoes are provided with soles and upper portions which conform to the configuration of the user's feet by the use of vacuum formable bladders in the sole of the shoes and/or in the sides of the upper portions of the shoes. The bladders are filled with material, such as small spherical particles, which retains a configuration conforming to the shape of the feet under reduced pressure conditions. A vacuum pump is provided, and it may be located in the heel area of the shoe to be actuated by walking or running to evacuate air from the bladders.
