Abstract
An inner sole includes a heel air bag for supporting the heel and a first arch air bag for supporting the plantar arch which is connected to the heel air bag through a passageway. The heel air bag and the primary arch air bag are coupled to the bottom surface of the inner sole. A second arch air bag is disposed over the first arch air bag to communicate with the primary arch air bag. When the heel air bag is pressed, air pressure is uniformly applied to the second arch air bag through the first arch air bag.
