A jogging shoe has an adjustable shock absorbing system for the heel impact surface in the form of an inflatable air chamber with downwardly extending pump-like pegs and the hollow cavity interiors in communication with the air chamber. When the jogging shoe impacts against the running surface, the pegs depress, compressing air contained in their cavities into the air chamber which distributes the impact force across the entire sole of the shoe. After the pegs depress, the air chamber can also partially compress to absorb the remainder of the force. Thus a two-step shock absorption and distribution system is provided.
