Description: SHOCK ABSORPTION SYSTEM FOR SHOES TECHNICAL FIELD This invention relates to a shock absorption device of a shoe, and particularly, to a shock absorption system positioned in the heel of a shoe. More particularly, this invention relates to a high technology like a automobile shock absorption system for shoes that makes incredible energy rebound and shock absorption for high pressure impact, and maintain a good stability. BACKGROUND ART Generally, cushion inner soles have been provided for shoes and boots which are formed of a compressible,elastic material such as cellular plastic foams, foam rubber,etc. These inner soles have provided only limited shock absorbency,resulting in a little or no significant improvement in wearer's comfort. Some prior art have provided inner soles with air cushions at either the toe and heel areas,and some have provided cushions at both areas with circulation between the air cushions. The cushions have been provided with mechanisms to circulate air and ventilate the shoe or boots during walking activities. Examples of these are: U.K.Pat.Nos.2, 189,679 and 357,391: U.S. Pat. Nos.3, 180, 039, 2, 716, 293, 1 , 213, 941 and German Pat. No. 3, 144, 207.
