It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0043] like Figure 1-Figure 8 As shown, Figure 1 This is a bottom view of the foot bones in an exemplary embodiment of the present application. As can be seen from the figure, the bones in the foot that mainly bear the force during walking and standing include the first metatarsal d, the medial cuneiform e, the navicular f, the talus g, the fifth metatarsal tuberosity h, the cuboid bone i, and the calcaneus j. The bottom surface 1 of the balance piece should cover the gaps between these bones to provide support for the foot bones.

[0044] In one embodiment, the leather shoe heel provided by the present application comprises a balancing piece 3 and a back cover 2, wherein the balancing piece 3 is arranged between the sole 1 and the back cover 2 which is in contact with the sole 1;

[0045] The balance sheet 3 includes six supporting points, the first supporting point A is set at the rear end point of the sole 1, the second supporting point a is set at the concave point of the convex arc portion of the rear upper 2, the third supporting point B is set at the left inner edge of the sole 1 at 1 / 5 from the back to the front, the fourth supporting point b is set at the right inner edge of the sole 1 at 1 / 5 from the back to the front, the fifth supporting point C is set at the left inner edge of the sole 1 at 1 / 2 from the back to the front, and the sixth supporting point c is set at the right inner edge of the sole 1 at 1 / 2 from the back to the front;

[0046] The plane formed by the first support point A, the third support point B, the fourth support point b, the fifth support point C, and the sixth support point c is the bottom surface 31 of the balance sheet, and the bottom surface 31 of the balance sheet is used for sole support;

[0047] The curved surface formed by the first supporting point A, the second supporting point a, the third supporting point B, and the fourth supporting point b is a convex arc surface 32 of the balance piece, and the convex arc surface 32 of the balance piece bulges backwards and cooperates with the bottom surface 31 of the balance piece to achieve heel anti-twist protection;

[0048] The back cover 2 includes a shoe cover 21 made of high-resilience foam material, which is arranged in the central area of ​​the upper end of the second supporting point a and extends obliquely upward and backward. An arc-shaped ridge 211 is provided at the bottom of the inner surface of the shoe cover 21, and the arc-shaped ridge 211 is used to isolate the upper part of the shoe cover 21 from the foot to avoid rubbing the foot.

[0049] like Figure 2 As shown, Figure 2 : This is a schematic diagram of the relationship between the bottom surface 31 of the balance sheet and the foot bones in an exemplary embodiment of the present application; wherein, the root bone j is located at the sole of the foot and is the largest bone in the foot. Therefore, in one embodiment, a cavity 311 is provided in the middle of the plane formed by the first support point A, the third support point B, and the fourth support point b, and the cavity 311 is used to improve the shock absorbing effect. The cavity 311 at the position of the root bone j allows the sole of the foot to contact the sole material that is softer than the balance sheet 3, so as to absorb the impact force of the bottom surface, improve the wearing experience, and improve the shock absorbing effect.

[0050] like Figure 3 As shown, Figure 3 It is a right side schematic diagram of the relationship between the balance plate 3 and the foot bones in an exemplary embodiment of the present application; the second support point a is located at the most concave part of the heel, and by setting the balance plate convex arc surface 32 at the first support point A, the second support point a, the third support point B, and the fourth support point b, the root bone j can be completely wrapped to avoid ankle sprains.

[0051] In one embodiment, the straight-line distance between the first supporting point A and the third supporting point B is equal to the straight-line distance between the first supporting point A and the second supporting point a.

[0052] In one embodiment, if Figure 2 , Figure 4 As shown, Figure 4 Schematic diagram of the relationship between the bottom surface 31 of the balance sheet and the sole of an exemplary embodiment of the present application; the plane formed by the third support point B, the fourth support point b, the fifth support point C, and the sixth support point c is an X-shaped structure 312. The X-shaped structure 312 can reduce the area of ​​the balance sheet 1 and reduce costs, while still maintaining the structural effect of the balance sheet. In a specific embodiment, the X-shaped structure 312 can be displayed when viewed from the bottom surface of the sole to improve the design effect of the sole.

[0053] In one embodiment, if Figure 2 , Figure 4 As shown, preferably, the straight-line distance between the first supporting point A and the third supporting point B is equal to the straight-line distance between the first supporting point A and the second supporting point a.

[0054] In one embodiment, the ratio of the area of ​​the cavity 311 to the area of ​​the plane formed by the first support point A, the third support point B, and the fourth support point b is 0:1 to 0.5:1. Practice shows that if the area of ​​the cavity 311 is too large, the supporting function of the balance sheet 3 will fail, and if it is too small, it will lead to poor wearing comfort and poor shock absorption effect. In one specific embodiment, the cavity 311 is elliptical; in another specific embodiment, the cavity 311 is circular. The cavity 311 can also be a triangle, a trapezoid, a five-pointed star or an irregular shape, which is not limited by the present application.

[0055] In one embodiment, the thickness of the balance sheet 3 is greater than or equal to 1.5 mm. The balance sheet 3 can be made of TPEE material. TPEE, which is called Thermoplastic Polyester Elastomer, is a block copolymer composed of a crystalline polyester hard segment with a high melting point and high hardness and an amorphous polyether or polyester soft segment with a low glass transition temperature to form a two-phase association structure. TPEE has the softness and elasticity of rubber and the rigidity and easy processing of thermoplastics, and its Shore hardness ranges from 28 to 82. TPEE material also has the characteristics of toughening grade, low temperature resistance, high impact resistance, and aging resistance, and is recyclable and reusable, with green and environmentally friendly characteristics, and has unique advantages in low temperature impact resistance, tear resistance and cost-effectiveness. In order to achieve the effect of supporting and anti-twisting and protecting the balance sheet 3, the present application selects a TREE balance sheet 3 with a thickness greater than or equal to 1.5 mm. In a specific embodiment, a TREE balance sheet with a thickness of 2 mm can be preferably used. In another specific embodiment, materials similar to TPEE such as thermoplastic elastomer (TPE), TPU (thermoplastic polyurethane), PEBA (nylon elastomer), etc. may also be used, but the present application is not limited to this.

[0056] In one embodiment, the Shore A hardness of the balance sheet 3 is greater than or equal to 70 degrees. Improving the hardness of the material selected for the balance sheet 3 can reduce the thickness of the balance sheet 3, making the shoe itself lighter. The convex arc surface 32 of the balance sheet needs a higher hardness to meet the needs of anti-twist and straightening. In a specific embodiment, the Shore A hardness of the bottom surface 31 of the balance sheet is greater than or equal to 70 degrees, and the Shore A hardness of the convex arc surface 32 of the balance sheet is greater than or equal to 80 degrees.

[0057] In one embodiment, if Figure 7As shown, the shoe 21 and the convex arc surface 32 of the balance piece are integrally molded. The shoe 21 follows the principle of ergonomics and simulates the process of putting on and taking off a shoe horn. A shoe 21 that is concave forward is provided in the central area of ​​the upper end of the second support point a. The shoe 21 is made of high-resilience foam. The high-resilience foam can quickly return to its original shape after compression and is not easy to deform. It also has good flame retardancy and anti-aging properties. High-resilience foam can be made of polyurethane or polyether as raw materials to produce a sponge with a mixed pore diameter and a large open porosity, providing better support and comfort. The shoe 21 and the convex arc surface 32 of the balance piece are integrally molded. The shoe 21 and the convex arc surface 32 of the balance piece have a smooth transition and can fit the concave arc of the heel amplitude, so that the user can put on and take off the shoes without squatting down, freeing both hands, and stepping into the shoes with the heel, which is more convenient to take off the shoes. An arc-shaped ridge is provided at the bottom of the inner surface of the shoe strap 21, and the arc-shaped ridge 211 is used to isolate the upper part of the shoe strap 21 from the foot to avoid rubbing the foot. The arc-shaped ridge 211 is an easily rubbed part, and the crescent-shaped soft foam protrusion is used to isolate the upper edge of the heel from the skin, thereby achieving the effect of not rubbing the heel.

[0058] In one embodiment, the height of the shoe strap 21 is 15 mm. The shoe strap 21 is tilted upward and backward by 30 degrees, which makes it easier to put on and take off, and avoids rubbing the heels.

[0059] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0060] Although some specific embodiments of the present application have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only, rather than for limiting the scope of the present application. It will be appreciated by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments may be combined in any manner. However, it will be apparent to those skilled in the art that the various modifications to these embodiments may be made, and the general principles defined in the present application may be implemented in other embodiments without departing from the spirit or scope of the present application.
