Abstract
The present invention relates to a buffer device of sport shoes having a plurality of air chamber buffer elements disposed at the appropriate positions on the sole of the shoes, and a ventilation tube of each air chamber buffer element is connected to an air bag on which an air valve is fixed for supplying air from outside. When the air in the air bag and each of the air chamber buffer elements is saturated, the pressure in the air bag and each air chamber buffer element reaches equilibrium, such that the internal air pressure of the air bag or the air chamber buffer element is compressed by the feet and the air is pressed into the air bag or any one of the air chamber buffer elements, and thus attains the effect of elastic buffering for the feet. The air can be refilled any time by the user's wearing the shoes and walking after the air leaks to the outside.
