1 . A sole assembly of a shoe comprising
 an outsole; and   a socklining on top of the outsole and comprising an air chamber in a heel region; an airbag in the air chamber, the airbag including a plurality of front outlets for expelling air from the airbag forwardly, and a rear check valve for permitting air to enter the airbag but not to exit the airbag; and a resilient support in the airbag.   
     
     
         2 . The sole assembly of  claim 1 , wherein the airbag comprises a top layer section and a bottom layer section formed of a material the same as that of the top layer section but hardness different from the top layer section. 
     
     
         3 . The sole assembly of  claim 2 , wherein the resilient support is disposed on the top layer section. 
     
     
         4 . The sole assembly of  claim 2 , wherein the resilient support is disposed upper of the bottom layer section. 
     
     
         5 . The sole assembly of  claim 2 , wherein the resilient support is disposed between the top layer section the bottom layer section. 
     
     
         6 . The sole assembly of  claim 1 , further comprising an inlet formed integrally with the check valve for permitting air to enter the check valve. 
     
     
         7 . The sole assembly of  claim 1 , further comprising a plurality of channel extending forward, each channel the air flowing in communication with the outlet. 
     
     
         8 . The sole assembly of  claim 7 , wherein the channels comprises a plurality of perforations on the front portion thereof.
