PURPOSE: A buffering device for shoes is provided to prevent the reduction of a buffer function caused by the rapid discharge of air filling a specific buffer space on the shoes. CONSTITUTION: A buffering device for shoes includes front and rear air chambers(20) and an air channel(30). The front and rear air chambers are filled with the fixed volume of air. Each air chamber receives the body weight of a user through the front and rear parts of feet. The front air chamber is formed with left and right units. Each air chamber is produced with spiral shaped flow paths for inducing the flow of air.
