A main object of the present invention is to enable anyone to replace a worn out or damaged heel simply by pulling out the heel and inserting a new heel without using a separate adhesive or work piece and a fastening element during replacement of the heel. Another object of the present invention is to securely hold a replaced heel and restrict the heel in horizontal, vertical and back-and-forth directions while in use to prevent separation and disengagement, thereby improving usability. Still another object of the present invention is to reduce shoe repair costs once a heel of the shoe is replaced and resolve any inconvenience and trouble involved in requesting repair by a shoe repair expert, thereby motivating customers to purchase shoes, as well as to increase the life of those shoes, thereby improving the economic value and be environmentally friendly. In particular, the present invention is adapted to running shoes since the heel has an airbag inserted therein and can absorb dual impact thereby enhancing the function of the shoes. |
