ABSTRACT:
A shoe, particularly a sport shoe, has a sole with a shallow recess therein that is closed by a lining impervious to air. The upper of the shoe also has air chambers therein, in surrounding relationship to the heel, these latter chambers also communicating with the air chamber of the sole. A crescent-shaped piece at the rear of the upper protects the Achilles' tendon of the wearer and is hollow and flexible and communicates with the air chamber in the shoe sole. As a result, the air chambers can deform substantially so as to absorb shock and protect the rear of the foot of the wearer, at the same time that the pressure in the various chambers does not greatly change.
