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 a pair of female heel shoes capable of relieving foot pressure and a preparation method of the female heel shoes.

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. 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, since the height of the high-heeled shoes with the adjustable roots needs to be adjusted by hands, on one hand, the difference of the heights of the left high-heeled shoe and the right high-heeled shoe can be caused by errors, and the wearing comfort is affected. On the other hand, the left and right high-heeled shoes have different wear degrees, so that the heights of the high-heeled shoes are different, and the adjustment of the heights of the heels is troublesome.

Furthermore, the operation of application trigonometric function reachs two torsion points of the interior body outer body both sides of shoes, and these two torsion points can form stable triangular structure with heel top central point, increase the stability of shoes to increase the travelling comfort of wearing. Because the sole of the human body is not flat but has a certain radian, the lowest points of the profile of the forefoot are 2, and the 2 lowest points are the main acting points of the front part of the foot plate contacting with the ground, and can also be understood as the torsion points of the foot plate contacting with the ground when the shoe is not worn and the human is walking or standing. The bottom of the shoe is designed into 2 torque points protruding towards the direction of the floor according to the natural outline of the sole of the human body, so that the supporting of the shoe to the foot can be enhanced, the human body weight is prevented from falling into the half sole part of the foot, and the pressure of the human body weight to the half sole of the foot is reduced. When the 2 torsion points do not exist, when the shoe is worn, the weight of the human body is increased along with the inclination of the shoe, and the force acting on the half sole of the foot is increased; when 2 torsion points protruding towards the floor are designed behind the bottom of the shoe, the 2 torsion points form 2 points for supporting weight, and the original weight falling into the forefoot is dispersed by the 2 torsion points, so that the pressure on the forefoot is greatly relieved.

In addition, the thickness of the filling part is obtained by the pressure value after the wearer wears the foot-protecting bag, so that the phenomenon that the uniform thickness of the filling part brings different uncomfortable feelings to the wearers with different weights and similar feet is avoided. When a user sits down and keeps a fixed heel lifting posture, the thickness of the filling part is combined with the second flexible covering block which can be folded for 180 degrees and is used as the toe cap part of the shoe, the pressure of the foot is effectively absorbed by the filling part and the second flexible covering block which can be folded for 180 degrees and is used as the toe cap part of the shoe, the stress intensity is reduced, and the comfort level of the foot is improved. If the toe part can not be folded easily, when the 2 torsion points support the forefoot, the rear part of the forefoot is located on the 2 torsion points, at this time, the front end of the forefoot can generate an upward acting force, if the toe part can not be folded, the upward acting force generated on the front end of the forefoot can form a downward acting force, and the downward acting force is applied to the forefoot, so that the forefoot can feel pressure; when the toe cap part can be easily folded and the front end of the forefoot can generate an upward acting force, the forefoot can be easily tilted along with the foldable toe cap without bearing too much pressure;

in addition, the paper midsole and the soft bottom sheet are used, so that the weight of the shoe is effectively reduced, and the wearing comfort of a wearer is improved.

In general, the invention improves the comfort of the wearer, and the length of the heel does not need to be designed into the heel with adjustable length, thereby avoiding the inconvenience brought by the heel with adjustable length.

5.1, pre-digging out the foot bed filler on the construction path of the locking nail hole for exposing the heel preset nut, fixing the hard insole by using a steel screw to achieve seamless connection of the heel, finally backfilling the dug-out filler, and restoring the foot bed to be flat so as to form the stable triangular-structure heel locking nail construction method.

5.2 fix the heel with direct nailing, backfill the foot bed:

nailing the heel and the hard insole, digging out the filler of the 'sponge-like soft full-cushion type foot bed' with the area required by construction at the construction site, and backfilling the dug-out foot bed filler after nailing to restore the flatness of the foot bed.
