[0042] like Figure 1-Figure 7 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.

[0043] The present application provides a balancing plate for supporting anti-twist and correcting in-shoes, wherein the balancing plate 3 is arranged between a sole 1 and a back cover 2 which is in contact with the sole 1; the balancing plate 3 includes six supporting points, wherein a first supporting point A is arranged at a rear end point of the sole 1, a second supporting point a is arranged at a concave point of a convex arc portion of the back cover 2, a third supporting point B is arranged at a left inner edge of the sole 1 at 1 / 5 from the back to the front, a fourth supporting point b is arranged at a right inner edge of the sole 1 at 1 / 5 from the back to the front, a fifth supporting point C is arranged at a left inner edge of the sole 1 at 1 / 2 from the back to the front, and a sixth supporting point c is arranged at a left inner edge of the sole 1 at 1 / 2 from the back to the front. The right inner edge of 1 / 2 of 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 plantar support; 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 absorption effect; the curved surface formed by the first support point A, the second support point a, the third support point B, and the fourth support point b is the convex arc surface 32 of the balance sheet, and the convex arc surface 32 of the balance sheet bulges backwards and cooperates with the bottom surface (31) of the balance sheet to achieve heel anti-twist protection.

[0044] 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, a cavity 311 can be set at the position of the root bone j so that the sole of the foot can 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 enhance the shock absorption effect.

[0045] 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.

[0046] 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.

[0047] In one embodiment, if Figure 2 , Figure 4 As shown, Figure 4Schematic 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.

[0048] In one embodiment, if Figure 2 , Figure 4 As shown, the area ratio of the cavity 311 to the plane formed by the first support point A, the third support point B, and the fourth support point b is 0 to 0.5. Practice shows that if the area ratio of the cavity 311 is too large, the supporting function of the balance sheet 3 will fail, and if the area ratio is too small, it will lead to poor wearing comfort and poor shock absorption effect. In a 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 in this application.

[0049] 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.

[0050] In one embodiment, preferably, the Shore A hardness of the bottom surface 31 of the balance sheet exceeds 70 degrees, and the Shore A hardness of the convex curved surface 32 of the balance sheet exceeds 80 degrees. Increasing 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 curved surface 32 of the balance sheet needs a higher hardness to meet the needs of anti-twist and straightening.

[0051] In one embodiment, if Figure 7 As shown, Figure 7 It is a right view of a balance sheet including an extended baffle in an exemplary embodiment of the present application. The center area of ​​the upper end of the second support point a is provided with a balance sheet concave arc surface 33 extending obliquely backward and upward and concave forward. The balance sheet concave arc surface 33 is used to facilitate wearing and taking off. The balance sheet concave arc surface 33 follows the principle of ergonomics and simulates the process of wearing and taking off a shoe horn. The balance sheet concave arc surface 33 with a "crescent-shaped" slightly curved arc is provided in the center area of ​​the upper end of the second support point a. The balance sheet 3 has a certain hardness and maintains a concave arc that can fit the amplitude of the heel, so that the user can put on and take off the shoes without squatting down, freeing both hands, and the heel can be stepped into the shoe, which is more convenient to take off the shoes.

[0052] In one embodiment, if Figure 7 As shown, the concave arc surface 33 of the balancing piece transitions smoothly with the convex arc surface 32 of the balancing piece.

[0053] In one embodiment, if Figure 7 As shown, the left and right sides of the front end of the convex arc surface 32 of the balance plate are both extended with extended baffles 34 extending forward and upward obliquely, and the extended baffles 34 surround the ankle to prevent the ankle from twisting and protect it.

[0054] The present application also provides a shoe for supporting anti-twist and correction, comprising a sole 1 and a back cover 2, wherein a balance sheet 3 provided in any of the above embodiments is arranged between the sole 1 and the back cover 2 which is in contact with the sole 1.
