A shoe sole for a shoe comprises: an air chamber formed of a resilient material and defining an inner space for receiving air therein; an air valve coupled to the air chamber; and a sole member formed of a resilient material and coupled with the air chamber, the sole member enclosing a substantially entire outer surface of the air chamber except some portions of the air chamber and the air valve such that a wearer of the shoe can selectively open and close the air valve to adjust an air pressure of the air chamber, and thus, to adjust an air cushioning degree of the shoe. The air chamber can include a grooved structure on the generally planar upper and lower surfaces and on side surfaces thereof, and one or more through-holes formed through the upper and lower surfaces of the chamber, and the sole member is filled in the through-holes.
