Heels and the Manufacturing Method for Rear Hoof of High-heeled Shoes}

The present invention relates to a shoe heel for a high heel and a method of manufacturing the same, and more particularly, to absorb a shock applied from the ground by using a shoe heel, a walking or a double motion, which is replaced and used in the heel of a high heel, and prevents slipping. Easy to make shoe heel, such as to reduce the fatigue caused by walking or cantilever movement to the person wearing high heels, to prevent the joints from going too much, to prevent safety accidents due to slipping, and to improve productivity with ease of production and high quality It relates to a high-heeled heel shoe and a method of manufacturing the same to make a shoe heel.

In general, the height of the heel of the shoe is about 3 ~ 5㎝ is appropriate, and more than that has been reported to the medical community to give a burden to the human body. However, for the reason that the shoes look taller or fashion, forcing women to raise the height of the heel of shoes, many problems are exposed.

In other words, when studying the basic gait of the human body, four steps should be naturally performed: when the heel is grounded, when the entire sole of the foot is grounded, when the heel is raised from the ground, and when the ground is pushed back. Only balanced walking can be achieved.

The high-heeled women's shoes, that is, high-heeled shoes, give rise to the overall musculoskeletal system such as ankles and knees due to the impact that is grounded with the ground when walking, thereby increasing energy consumption and muscle fatigue.

In addition, when the high heels of the appropriate height are worn, excessive load is applied to the forefoot and the ball of the foot, resulting in unnatural walking, such as deformation of the shape of the foot and abnormality in the spine, which may impair the balance of the human body. I'm doing it.

Shoe bends coupled to the heels of the high heels, the most to support the body of the woman when walking or walking, there is a problem that must be easily replaced and replaced frequently.

That is, the shoe heel is mainly made of a hard synthetic resin material to prevent easy wear, but its size is so small that it can not withstand the wear caused by supporting the female body to be replaced frequently.
