Description

Ergonomic folding female heel shoe and preparation method thereof

Technical Field

The invention relates to the technical field of high-heeled shoes, in particular to a pair of female heel shoes, and particularly relates to an ergonomic folding female heel shoe.

Background

High-heeled shoes, sometimes also called women's heels, are shoes with particularly high heels, so that the heels of a person wearing the shoes are obviously higher than the toes. High-heeled shoes have many different styles, especially on the change of heels, such as thin heels, thick heels, wedge-shaped heels, nail-shaped heels, mallet-shaped heels, knife-shaped heels and the like. Because high-heeled shoes need stronger stability, the traditional vamp fabric made in China is not suitable. And (5) manufacturing high-heeled shoes. The most conventional and most comfortable fabric to wear is animal leather such as cow leather, sheep leather and the like, and the best is of course first layer cow leather; however, animal leathers are expensive to manufacture and have high demands on manufacturers, so artificial leathers are produced. The artificial leather has the advantages of low manufacturing cost, capability of being produced in a batch mechanical mode and meeting the requirements of the industrialized society. With the development of technology, the artificial leather can be made to be similar to real leather, and PU leather is typical.

In the last 50 th century, the heel is the most important period in the history of high-heeled shoes, and the heel of the early high-heeled shoes can only be funnel-shaped due to the limitation of shoe manufacturing technology and materials, namely, the heel is narrowed from the sole and is enlarged to the bottom. The heel can be developed into a straight shape later, but the beauty of the lines is still lacked. Until the 50 s of the steel nail technology reformed high-heeled shoes, designers could design sharp heels. When the height of the high-heeled shoes rises to 6-8 cm, the center of gravity of the human body naturally moves upwards when walking. One study found that if you wear 7 cm high-heeled shoes for 2 hours, neck stiffness increases by 22%, and health professionals generally do not recommend that people who face computers for a long time wear 6-8 cm high-heeled shoes, which only causes the neck of people to become increasingly tired.

It can be seen that the higher the height of a high-heeled shoe, the greater the pressure on the human foot and thus the greater the negative impact on human comfort and foot health. It is desirable to wear both high-heeled shoes and the foot with the high-heeled shoes without the discomfort associated with wearing them. In more formal office occasions, clear text or plain text regulations require women to wear high-heeled shoes. Therefore, the high-heeled shoes with the adjustable root parts can be produced, and when people feel that the high-heeled shoes are uncomfortable to wear, the height of the root parts can be adjusted to be low, so that the stress state of feet is improved. However, in the prior art, it is very troublesome to manually adjust the height of the root. In addition, the problem that the foot is subjected to excessive pressure cannot be fundamentally solved by adjusting the height of the root, and the pressure of the foot is only transferred from the forefoot and is not relieved. Even though some high-heeled shoes are provided with an additional layer for buffering pressure in the market, the additional layer for buffering pressure cannot play the best role because the foot deviates from the initial position during walking.
