[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] Example 1
[0034] The present application embodiment discloses a shock-absorbing and sprain-proof shoe. Figure 1 The shock-absorbing and sprain-proof shoes include a sole body 1 and an upper body 2 , wherein the upper body 2 is fixed on the sole body 1 .
[0035] Reference Figure 1 and Figure 2, the sole body 1 includes a first midsole 11 and a second midsole 12, the first midsole 11 is fixedly arranged on the second midsole 12, the first midsole 11 is fixedly connected to the upper body 2, and the second midsole 12 is used to abut against the ground; the rebound performance of the first midsole 11 is greater than the rebound performance of the second midsole 12. In this embodiment, the sole body 1 is made of EVA material, and the rebound performance of the EVA material sole is related to factors such as the content of vinyl acetate (VA) and the use of additives. For example, the higher the content of vinyl acetate in the EVA material sole, the softness, elasticity and other properties of the EVA material are also improved. On the contrary, when the content of vinyl acetate decreases, the rigidity of the EVA material sole increases and the wear resistance increases. In this embodiment, the content of vinyl acetate in the first midsole 11 is greater than the content of vinyl acetate in the second midsole 12; thereby achieving good softness and elasticity of the first midsole 11, and a certain rigidity and good wear resistance. In other embodiments, the staff can adjust the use of additives in the first midsole 11 and the second midsole 12 to achieve different performances of the first midsole 11 and the second midsole 12 .
[0036] When the wearer's foot interacts with the ground, the first midsole 11 has good rebound performance, so that the first midsole 11 has good rebound and buffering performance, reducing the impact force on the wearer and improving the wearer's foot feel. The second midsole 12 in contact with the ground has a smaller rebound performance and less elastic deformation; thus, the second midsole 12 has good contact with the ground, so that the second midsole 12 has a good supporting effect on the wearer's foot.
[0037] The staff puts the EVA material of the first midsole 11 and the EVA material of the second midsole 12 into the shoe mold in sequence, and after heating and pressurizing, they are bonded into the sole body 1. Thus, the first midsole 11 and the second midsole 12 cooperate with each other, so that the sole body 1 has both rebound and shock-absorbing performance and good support, reducing the risk of spraining the wearer's foot due to excessive deformation of the sole body 1.
[0038] Reference Figure 2 In this embodiment, along the width direction of the upper body 2, the thickness of the first midsole 11 decreases from the middle to both sides; thereby, the middle area of the sole body 1 has a higher rebound and shock-absorbing performance, and the inner and outer sides of the second sole body 1 have a good supporting effect, which can further reduce the risk of the wearer's foot twisting to the inner and outer sides.
[0039] Reference Figure 1The sole body 1 further includes a support column 13, which is disposed on both sides of the first midsole 11 and the second midsole 12, and the support column 13 is integrally formed with the first midsole 11 and the second midsole 12. The material of the support column 13 may be consistent with that of the first midsole 11 or the second midsole 12, or the resilience of the support column 13 may be between that of the first midsole 11 and the second midsole 12. In this embodiment, the material of the support column 13 and the second midsole 12 is consistent, so that the support column 13 has a good supporting effect, so as to reduce the deformation degree of the inner and outer sides of the sole body 1, improve the supporting effect of the two sides of the sole body 1 on the wearer's feet, and further reduce the risk of the wearer's feet being sprained to both sides.
[0040] Reference Figure 1 The upper body 2 further includes a TPU protective sheet 21, which is fixedly connected to the first midsole 11 and is disposed around the first midsole 11. The TPU protective sheet 21 has a certain rigidity, thereby reducing the relative slip between the wearer's foot and the sole body 1, and reducing the side slip of the wearer's foot. The TPU protective sheet 21 has a good protective effect on the wearer's foot.
[0041] Example 2
[0042] The difference between this embodiment 2 and embodiment 1 is that:
[0043] Reference Figure 3 The sole body 1 also includes a plurality of energy-consuming plates 3, which are buried in the first midsole 11 and are arranged at intervals along the length direction of the sole body 1; the energy-consuming plates 3 are arc-shaped plates, and the opening direction of the energy-consuming plates 3 is arranged away from the upper body 2; the energy-consuming plates 3 can be made of thin steel plates, so that the energy-consuming plates 3 have deformation ability. In this embodiment, the energy-consuming plates 3 are corrugated plates. When the wearer's feet squeeze the arc-shaped energy-consuming plates 3 against the ground, the energy-consuming plates 3 will be compressed and deformed; thereby, the impact of the ground on the sole body 1 is partially converted into the internal energy of the energy-consuming plates 3 for dissipation, so as to further improve the shock-absorbing performance of the sole body 1. At the same time, the energy-consuming plates 3 will return to their original shape after being compressed, so as to further improve the rebound performance of the sole body 1. The energy-consuming efficiency of the energy-consuming plates 3 can be improved by designing the energy-consuming plates 3 in a wavy shape.
[0044] Example 3
[0045] The difference between this embodiment 3 and embodiment 2 is that:
[0046] Reference Figure 4 Both ends of the energy dissipation plate 3 extend into the second midsole 12 , so that the energy dissipation plate 3 acts as a connecting piece to improve the connection strength between the first midsole 11 and the second midsole 12 .
[0047] Example 4
[0048] The difference between this embodiment 4 and embodiment 2 is that:
[0049] Reference Figure 5 The sole body 1 further includes a plurality of tensile-resistant fibers 4, which are buried in the first midsole 11 and arranged on the side of the energy-consuming plate 3 away from the upper body 2. When the arc-shaped energy-consuming plate 3 is compressed and deformed, the two ends of the energy-consuming plate 3 exert a tensile force on the first midsole 11; thus, the tensile-resistant fibers 4 are arranged at the bottom of the energy-consuming plate 3, which can improve the tensile resistance of the first midsole 11 in the width direction, and extend the service life of the shoe.
[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
