Description:
TITLE OF THE INVENTION SHOCK-ABSORBING SHOES FIELD OF THE INVENTION The present invention relates to Shock-absorbing Shoes which are designed to reduce and absorb the shock given to the people during their walk, consequently relieving the pain from a long hours of walk and improving health of the people who wear them. In order to achieve the aforementioned purposes, the shock-absorbing part of the present invention is made of such thin and hard materials as thermal-compressed elastic and light-weight dried wood, spring metal sheet and hardened synthetic resin.

The shock-absorbing parts are provided on the middle of the sole, back of the sole or between the sole and the sole pad to effectively absorb the shock transferred to the back and other parts of the body of the people during their walk so that they feel comfortable during their long hours of walk.

BACKGROUND OF THE INVENTION The present invention relates to Shock-absorbing Shoes which are worn to the human feet. More specifically, the present invention relates to shock-absorbing shoes that are worn on the human feet and that provide shock-absorption for a wearer. In order to effectively achieve the aforementioned purposes, the absorbing part of the present invention made of such thin and hard materials as thermal-compressed elastic and light -weight dried wood, spring metal sheet and hardened synthetic resin is provided on the middle of the sole, back of the sole or between the sole and the sole pad to effectively absorb the shock transferred to the back and other parts of the body of the wearers.

According to the research studies related to the human feet, more than 40% of the weight of people is pressed down on the rear heel and 35% of the weight is distributed to the toes while the rest of the weight is distributed to other parts of the sole.

Therefore, the weight of the walker is pressed down to a specific part of the sole depending on how the person walks, exercises or stands. The shock is transferred to the brain through the sole, heel and back of the wearer of shoes and the pain caused by long hours of walk create many different types of diseases and such other adverse effects as back pain and memory-loss to the people who wear shoes that are not provided with shock-absorbing system.

Many type of shoes such as dress shoes, sneakers, walking shoes, etc. presently available on the market all over the world are designed to provide some level of shock- absorption for the wearers. According to the similar types of Korean patent Nos. 91- 1212 and 97-04363, the shoes from these inventions provide air ventilation and air- pumping functions and comfortable feeling to the wears of them, but they cannot protect the wearer against injury resulting from impact of the wearer's feet on a floor or other hard surfaces.

To solve the foregoing, the present invention is designed to lose and absorb shock in the shoe so that the wearer can feel comfortable and protect his/her body from injury.

SUMMARY OF THE INVENTION As described, the purpose of the present invention is to provide shock-

absorbing in the shoes to protect the wearer from injury. Shock-absorbing materials are provided in the middle of the sole, back of the sole or between the sole and the sole pad to effectively absorb the shock pressed down to the back and other parts of the body of the people during their walk so that they feel comfortable during their long hours of walk, without injury or pain. As the absorbing part of the present invention is made of such thin and hard materials as thermal-compressed elastic and light-weight dried wood, spring metal sheet and hardened synthetic resin, it provides and maintains constant resilience without distortion.
