Description

Technical Field

[0001] The present application relates to the technical field of shoes, and in particular to a high-resilience sole and a shoe. Background Art

[0002] In the prior art, high-rebound materials are often used to make shoe soles, so that the soles have high resilience to cushion the impact of the ground on the wearer's feet and improve the comfort of the wearer's feet.

[0003] However, when the sole body is made of high-rebound material as a whole, if the impact force of the ground on the sole is large, the deformation of the sole body will also increase accordingly; and due to the uneven impact force of the ground on the sole body, the deformation of different areas of the sole body is also different, which makes the wearer's foot prone to sprains. Utility Model Content

[0004] In order to take into account the protective performance of the high-rebound sole, the present application provides a high-rebound sole and a shoe.

[0005] The present application provides a high-resilience sole and shoes, which adopt the following technical solutions:

[0006] A high-rebound sole comprises a sole body, wherein the sole body comprises a first elastic midsole and a second elastic midsole, wherein the first elastic midsole is fixedly arranged on the second elastic midsole, the resilience of the first elastic midsole is higher than the resilience of the second elastic midsole, and the second elastic midsole is used for contacting with the ground.

[0007] By adopting the above technical solution, the resilience of the first elastic midsole is better than that of the second elastic midsole, and the support performance of the second elastic midsole is better than that of the first elastic midsole. The high resilience of the first elastic midsole can make the sole body have high resilience, and while the second elastic midsole has a certain resilience, the second elastic midsole has a good support effect on the wearer's foot, which can reduce the excessive deformation of the sole body, thereby improving the support effect of the sole body on the wearer's foot and reducing the occurrence of the wearer's twisted foot and foot rollover.

[0008] Optionally, the thickness of the first elastic midsole decreases along the direction from the heel to the toe of the sole body.

[0009] By adopting the above technical scheme, when the wearer's foot lands on the ground, the heel of the sole body has a greater impact on the ground; by increasing the thickness of the first elastic midsole of the heel to improve the high resilience of the heel of the sole body, the heel of the sole body has a buffering and shock-absorbing effect on the impact of the ground, thereby improving the comfort of the wearer's foot.

[0010] When the wearer's foot leaves the ground, the sole of the sole body contacts the ground, and the thickness of the first elastic midsole in the sole of the sole body is relatively large, thereby improving the resilience of the sole of the sole body to help the wearer's foot leave the ground.

[0011] Optionally, the sole body further includes a wear-resistant outsole, and the second elastic midsole is fixed on the wear-resistant outsole; and a plurality of support columns are laid on a side of the wear-resistant outsole away from the second elastic midsole.

[0012] By adopting the above technical solution, the wear-resistant outsole has a greater friction effect with the ground, so that the sole body has a wear-resistant and anti-slip effect.

[0013] Optionally, an anti-slip groove is provided on a side of the support column away from the second elastic midsole.

[0014] By adopting the above technical solution, the anti-skid grooves at the bottom of the support column increase the roughness of the bottom of the support column, further improving the anti-skid effect of the sole body.

[0015] Optionally, the wear-resistant outsole is bonded and fixed to the side walls of the first elastic midsole and the second elastic midsole at the heel portion of the sole body.

[0016] By adopting the above technical solution, the wear-resistant outsole covers the first elastic midsole and the second elastic midsole at the heels of the shoes, so as to reduce the wear of the first elastic midsole and the second elastic midsole at the heels of the shoes.

[0017] Optionally, the distance from the heel of the wear-resistant outsole to the sole body decreases along the direction away from the toe.

[0018] By adopting the above technical solution, the wear-resistant outsole arranged obliquely can improve the contact between the sole body and the ground, thereby improving the anti-slip effect of the sole body.

[0019] A shoe comprises any one of the above-mentioned sole bodies and an upper body, wherein the upper body is fixed on the sole body.

[0020] By adopting the above technical solution, the shoes have both high rebound and good protective performance.

[0021] Optionally, the heel portion of the wear-resistant outsole extends toward the sole body, and the wear-resistant outsole is fixedly connected to the upper body.

[0022] Through the above technical solution, the wear-resistant outsole covers the connection area between the first elastic midsole and the upper body, thereby further improving the connection strength between the sole body and the upper body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The high resilience of the first elastic midsole can make the sole body have high resilience, while the second elastic midsole has a certain resilience. The second elastic midsole has a good supporting effect on the wearer's foot, which can reduce the excessive deformation of the sole body, thereby improving the supporting effect of the sole body on the wearer's foot and reducing the occurrence of twisting and rolling of the wearer's foot;

[0025] 2. When the wearer's foot lands on the ground, the heel of the sole body has a greater impact on the ground; by increasing the thickness of the first elastic midsole at the heel, the high resilience of the heel of the sole body is improved, so that the heel of the sole body has a buffering and shock-absorbing effect on the impact of the ground, thereby improving the comfort of the wearer's foot;

[0026] 3. The wear-resistant outsole arranged obliquely can improve the contact between the sole body and the ground, and improve the anti-slip effect of the sole body. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a high-resilience sole and a shoe. Figure 1 The high-resilience sole and the shoe include a sole body 1 , and the sole body 1 includes a first elastic midsole 11 , a second elastic midsole 12 and a wear-resistant outsole 13 .

[0034] Reference Figure 1 The first elastic midsole 11 is fixed on the second elastic midsole 12, and the second elastic midsole 12 is fixed on the wear-resistant outsole 13. In this embodiment, the first elastic midsole 11 and the second elastic midsole 12 are integrally formed, and the second elastic midsole and the wear-resistant outsole 13 are bonded and fixed.

[0035] Reference Figure 1 and Figure 2 , a plurality of support columns 131 are laid on the side of the wear-resistant outsole 13 away from the second elastic midsole 12. An anti-skid groove 1311 is provided on the side of the support column 131 away from the second elastic midsole 12; the anti-skid groove 1311 at the bottom of the support column 131 increases the roughness of the bottom of the support column 131, thereby increasing the friction between the support column 131 and the ground, and improving the anti-skid effect of the sole body 1. In this embodiment, the wear-resistant outsole 13 is made of wear-resistant rubber, and the material parameters of the wear-resistant outsole 13 are: hardness coefficient 57+ / -2A, wear resistance coefficient DIN80, anti-skid coefficient 0.5; so that the sole body 1 has a wear-resistant and anti-skid effect.

[0036] Reference Figure 1 , the resilience performance of the first elastic midsole 11 is higher than the resilience performance of the second elastic midsole 12 .

[0037] In this embodiment, the first elastic midsole 11 is made of profoam EVA material, the hardness of the first elastic midsole 11 is 47±3C, and the rebound coefficient is 63%, so that the first elastic midsole 11 has good rebound performance.

[0038] The second elastic midsole 12 is a common EVA sole with good softness and support. In this embodiment, the hardness coefficient of the second elastic midsole 12 is 45+ / -2C, the wear resistance coefficient is DIN80, and the anti-slip coefficient is 0.4. Therefore, the second elastic midsole 12 has a certain rebound performance and has a good support effect on the wearer's foot, which can reduce the excessive deformation of the sole body 1. In this way, the support effect of the sole body 1 on the wearer's foot is improved, and the occurrence of twisted feet and foot rollover of the wearer is reduced.

[0039] That is, the first elastic midsole 11 is made of EVA material through a specific foaming process and has good resilience. The second elastic midsole 12 is made of EVA material directly foamed and also has certain resilience, and the second elastic midsole 12 is soft. The resilience of the first elastic midsole 11 is better than that of the second elastic midsole 12, and the supporting performance of the second elastic midsole 12 is better than that of the first elastic midsole 11. The staff can put the blanks of the first elastic midsole 11 and the second elastic midsole 12 into the shoe mold in turn, and bond them into the sole body 1 after heating and pressurizing.

[0040] In summary, the first elastic midsole 11 has a better resilience than the second elastic midsole 12, and the second elastic midsole 12 has a better support performance than the first elastic midsole 11. The high resilience of the first elastic midsole 11 can make the sole body 1 have high resilience, and the second elastic midsole 12 has a certain resilience, and the second elastic midsole 12 has a good support effect on the wearer's foot, which can reduce the deformation of the sole body 1, thereby improving the support effect of the sole body 1 on the wearer's foot and reducing the occurrence of twisted feet and foot rollover of the wearer.

[0041] When the wearer's foot lands on the ground, the heel portion of the sole body 1 provides greater support for the wearer's foot. In order to further improve the support effect of the sole body 1 on the wearer, the first elastic midsole 11 is further improved in this embodiment.

[0042] Reference Figure 1 , along the direction from the heel to the toe of the sole body 1, the thickness of the first elastic midsole 11 decreases. That is, the farther away from the toe direction, the greater the proportion of the first elastic midsole 11 relative to the second elastic midsole 12; the closer to the sole body 1 at the heel, the better the rebound performance and the softer the sole body 1. During the landing process of the wearer's foot, the heel of the sole body 1 has a greater impact on the ground; by increasing the thickness of the first elastic midsole 11 at the heel, the high rebound performance of the heel of the sole body 1 is improved, so that the heel of the sole body 1 has a buffering and shock-absorbing effect on the impact of the ground, and the comfort of the wearer's foot is improved.

[0043] Reference Figure 1 and Figure 2 At the same time, the wear-resistant outsole 13 is bonded and fixed to the sidewalls of the first elastic midsole 11 and the second elastic midsole 12 at the rear of the sole body 1. In addition, the distance from the rear of the wear-resistant outsole 13 to the sole body 1 decreases along the direction away from the toe, that is, the rear of the wear-resistant outsole 13 is tilted upward. When the wearer wears the shoes of the present application for running, the runner will use the heel to exert force, and the tilted wear-resistant outsole 13 can improve the contact between the sole body 1 and the ground, and also reduce the wear of the rear of the first elastic midsole 11 and the second elastic midsole 12. At the same time, when the runner passes the finish line and needs to stop suddenly, the rear of the wear-resistant outsole 13 has a greater contact with the ground, thereby improving the anti-skid effect of the sole body 1.

[0045] This embodiment 2 discloses a shoe, referring to Figure 3 and Figure 4, including the sole body 1 and the upper body 2 in embodiment 1, the upper body 2 is fixedly arranged on the sole body 1. At the same time, in this embodiment, the heel of the wear-resistant outsole 13 extends toward the sole body 1, and the wear-resistant outsole 13 is fixedly connected to the upper body 2. The wear-resistant outsole 13 covers the connection area between the first elastic midsole 11 and the upper body 2, so that the connection strength between the sole body 1 and the upper body 2 can be further improved. At the same time, the wear-resistant outsole 13 can protect the upper body 2 and reduce the risk of wear of the upper body 2.

[0046] 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.
