STRUCTURE OF SHOCK ABSORBER TYPE SHOE

PURPOSE: A shoe structure capable of absorbing impact is provided to disperse impact absorption capacity by changing the length of protrusions based on the weight applied on the shoe, thereby protecting the knee and ankle joints and improving reliability of the shoe. CONSTITUTION: A shoe structure capable of absorbing impact consists of a sole(30) at the bottom, an insole(10) surrounding a foot, and a mid-sole(20) in between the sole and the insole. The mid-sole is composed of a material having the elasticity of a flat pattern and contains a plurality of first protrusions(21) having a constant height in the front; second protrusions(22) with a lower height than those of the first protrusions are formed among the first protrusions; third protrusions(23) are formed on the center of the mid-sole with a constant height and constant space in-between the protrusions. The sole attached to the bottom of the mid-sole contains a first groove(31) for the insole on the upper edge. A second groove(32) is formed inside the first groove for the mid-sole, and a third groove is formed in front of the second groove for first and second protrusions.
