Claim:
An air cushion shoe sole, comprising: a tread member having a tread member upper surface, a tread member bottom surface with a tread formed thereon, a toe end, and a heel end, the tread member having a tread length extending from the toe end to the heel end; a hardened reinforcement sheet disposed over the tread member upper surface and extending substantially over the tread length, the hardened reinforcement sheet having a reinforcement sheet upper surface and a reinforcement sheet lower surface; a shoe liner detachably positioned at the reinforcement sheet upper surface in an unbonded state so as to be freely removable; the tread being formed as a non-slip cushion sheet integrally formed with the tread member at the tread member bottom surface; a nonskid member disposed in a recess formed in the tread member bottom surface; an air chamber formed in the tread member upper surface proximate said toe end, the air chamber being a first recess having a first recess opening; an air passageway extending from a rear side of the air chamber to a first air inlet formed at the heel end of the tread member, the air passageway being formed as a second recess in the tread member upper surface and defining a second recess opening and a second recess bottom; air pockets formed in the tread member main at predetermined positions below the air passageway, the air pockets being third recesses formed in the tread member having third recess openings formed at least in part by the second recess bottom; first air vents formed in the hardened reinforcement sheet proximate said toe end, the first air vents being fluid-communicated with the air chamber; the hardened reinforcement sheet being positioned onto the tread member upper surface to cover the second recess opening of the air passageway and the third recess openings of the air pockets; said shoe liner including a shoe liner main body having second air vents formed in the shoe liner main body proximate said toe end, the second air vents being fluid-communicated with the first air vents of the hardened reinforcement sheet, the shoe liner main body having a shoe liner upper surface and a shoe liner bottom surface, the second air vents communicating from the shoe liner upper surface to the shoe liner bottom surface with the shoe liner being configured such that the air cushion sole expels air through the second air vent to outside the shoe liner and into an interior of a shoe; and a cushioning layer having a honeycomb structured body at the shoe liner bottom surface, the honeycomb structured body having honeycomb-shaped grooves are formed in rows and open to a lower surface of the cushioning layer.
