Shoe sole with tunnel-type air chambers

1. A shoe sole comprising:

a main body including a recess formed at an upper surface thereof and a non-slip cushion sheet attached to a bottom surface thereof, in which pluralities of air chamber grooves are formed in the recess at a front portion of the main body and an air chamber groove is formed in the recess at a rear portion of the main body, and the air chamber grooves horizontally extend through both side walls of the main body;

a shoe liner for covering open upper portions of the air chamber grooves so as to provide pluralities of tunnel-shaped air chambers, in which an outer periphery of the shoe liner is attached to an outer periphery of the upper surface of the main body, and other portions of the shoe liner are inserted into the recess;

pluralities of air chamber grooves being arranged on a front portion of the lower surface of the shoe liner and an air chamber groove is arranged on a rear portion of the lower surface of the shoe liner, in which the air chamber grooves correspond to the air chamber grooves of the main body, respectively; and

an air chamber groove for providing a center air chamber in the shoe sole is formed at a center portion of the lower surface of the shoe liner, wherein a sealing protrusion is formed at a circumferential outer periphery of the air chamber groove and protrudes downwards from the lower surface of the shoe liner, wherein an air chamber groove for providing the center air chamber in the shoe sole is formed at a center portion of the upper surface of the main body and corresponds to the air chamber groove of the shoe liner, and wherein an engaging groove is formed at a circumferential outer periphery of the air chamber groove and corresponds to the sealing protrusion of the shoe liner.

pluralities of through holes being formed through the shoe liner, the through holes being formed at the front portion and the rear portion of the shoe liner, and the through holes being fluid-communicated with pluralities of air chamber grooves; and

an air chamber groove for providing a center air chamber in the shoe sole is formed at a center portion of the lower surface of the shoe liner, wherein a sealing protrusion is formed at a circumferential outer periphery of the air chamber groove and protrudes downwards from the lower surface of the shoe liner, wherein an air chamber groove for providing the center air chamber in the shoe sole is formed at a center portion of the upper surface of the main body and corresponds to the air chamber groove of the shoe liner, and wherein an engaging groove is formed at a circumferential outer periphery of the air chamber groove and corresponds to the sealing protrusion of the shoe liner.

pluralities of air chamber grooves being arranged on a front portion of the lower surface of the shoe liner and an air chamber groove is arranged on a rear portion of the lower surface of the shoe liner, in which the air chamber grooves correspond to the air chamber grooves of the main body, respectively;

an arched supporting portion being formed at a center portion of the upper surface of the shoe liner, the arched supporting portion bulging out at the upper surface of the shoe liner and corresponding to the shape of the sole of the foot; and

an air chamber groove for providing a center air chamber in the shoe sole is formed at a center portion of the lower surface of the shoe liner, wherein a sealing protrusion is formed at a circumferential outer periphery of the air chamber groove and protrudes downwards from the lower surface of the shoe liner, wherein an air chamber groove for providing the center air chamber in the shoe sole is formed at a center portion of the upper surface of the main body and corresponds to the air chamber groove of the shoe liner, and wherein an engaging groove is formed at a circumferential outer periphery of the air chamber groove and corresponds to the sealing protrusion of the shoe liner.
