Human body-balancing footwear capable of preventing knock-knees and providing cushioning suitable for the weight of wearer

Abstract

Disclosed is a footwear (including shoes, sneakers, and like, and hereinafter, referred to as “footwear”) which is produced on the basis of ergonomics, and which includes a heel part provided at a rear portion of a sole part, and an impact absorbing cap detachably coupled with the heel part. The footwear absorbs external impacts generated during walking as much as possible in three stages. The heel of the footwear is divided into a left section and a right section, and is replaceable at any time. The footwear prevents deformation in the ankle joint and knock-knees or bandy-legs caused by a difference in wear between the two heels of shoes.

1 . A human body-balancing footwear for preventing knock-knees and bandy-legs, the human body-balancing footwear comprising:
 a heel part provided at a rear portion of a sole part; and   an impact absorbing cap detachably coupled with the heel part.   
     
     
         2 . The human body-balancing footwear of  claim 1 , wherein the impact absorbing cap includes a first cap coupled with an inner side portion of the heel part corresponding to an inner portion of a foot of a user and a second cap coupled with an outer side portion of the heel part corresponding to an outer portion of the foot of the user, wherein the first and second caps are replaceable. 
     
     
         3 . The human body-balancing footwear of  claim 1 , wherein the impact absorbing cap includes a first cushion part coupled with a bottom surface of the heel part, a second cushion part coupled with a rear surface of the heel part, and a third cushion part linking the first cushion part with the second cushion part in a round form. 
     
     
         4 . The human body-balancing footwear of  claim 1 , further comprising a linking member linking the heel part with a front portion of the sole part along an edge of the heel part corresponding to an outer portion of a foot of a user, so that the user safely walks by allowing a tibia of the user to maintain balance of the user when the user walks, and the foot of the user is prevented from being flattened by allowing the tibia of the user to support a weight of the user when the user stands. 
     
     
         5 . The human body-balancing footwear of  claim 1 , wherein a plurality of impact absorbing caps having different impact absorbing degrees are provided, and one of the impact absorbing caps is selectively coupled with the heel according to a weight of a user. 
     
     
         6 . The human body-balancing footwear of  claim 1 , further comprising an impact absorbing unit provided at an upper portion of the sole part, wherein the impact absorbing unit includes:
 first cushion patterns prepared in a rectangular shape (“□”) and arranged on a surface of a heel section;   first support ribs prepared in a cross shape (“+”) and installed at a boundary part between the first cushion patterns;   second cushion patterns prepared in the rectangular shape (“□”) and arranged on a surface of a sole section;   second support ribs prepared in the cross shape (“+”) and installed at a boundary part between the second cushion patterns;   cushion balls installed at an intersection between the first cushion pattern and the first support rib which makes contact with a heel of a user foot;   a plurality of air holes formed on a bottom surface between the first cushion part and the first support rib;   a distribution passage provided in a transverse direction at a boundary part with the sole section by making a wall at an outer peripheral surface of the heel section;   a supply passage wall installed at a boundary part between the distribution passage and the sole section and having a plurality of supply passages; and   an air passage formed in the sole section and connected to the supply passage wall.
