Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a support plate and a sole and running shoes having the support plate. Background Technology

[0002] The support and stability of running shoes directly affect a user's running performance. Running shoes are usually required to have a certain degree of rebound performance to help users conserve energy, which is especially important for long-distance or high-speed running.

[0003] Carbon fiber plate shoes are popular among running enthusiasts due to their lightweight, elasticity, and stability. Currently, many running shoes on the market incorporate support plates (such as carbon fiber plates or TPU stabilizers) within the midsole.

[0004] However, current support plates for shoe soles primarily focus on their support capacity and energy return capabilities, resulting in relatively poor flexibility in bending. This is especially true for shoes with support plates on only one side, where poor flexibility can easily lead to runners twisting their ankles during running, thus increasing the risk of injury.

[0005] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0006] The purpose of this invention is to provide a support plate with relatively good bending flexibility and a relatively low risk of running injury, as well as a shoe sole and running shoes with the support plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A support plate comprising a front section, a middle section, and a rear section integrally connected from front to back;

[0009] The front section is arranged corresponding to the outer part of the forefoot of the human foot, the middle section is arranged corresponding to the outer part of the midfoot of the human foot, and the rear section is arranged corresponding to the outer part of the heel of the human foot.

[0010] The support plate has a notch on its outer side, and the notch is located at the junction of the front section and the middle section;

[0011] A horizontally arranged midfoot plate is integrally connected to the inner side of the middle section. The midfoot plate is arranged corresponding to the middle part of the human foot. The upper surface of the midfoot plate and the upper surface of the middle section are smoothly connected.

[0012] Preferably, the upper surface of the middle section gradually curves upward from the inside to the outside, and the upper surface of the rear section gradually curves upward from the inside to the outside. The upper surfaces of the middle section and the rear section together form an outer circumferential support surface.

[0013] Preferably, the lower outer side of the rear section is provided with a protrusion.

[0014] Preferably, a protrusion is integrally connected to the lower side of the midfoot plate.

[0015] A shoe sole, wherein the aforementioned support plate is embedded inside the midsole.

[0016] Preferably, the insole includes a first elastic layer and a second elastic layer stacked sequentially from top to bottom, and a first groove is formed on the lower side of the first elastic layer at a position corresponding to the support plate, and the support plate is embedded in the first groove.

[0017] Preferably, a second sink groove is formed at the lower end of the second elastic layer;

[0018] The bottom of the second settling tank is provided with a positioning through hole, and the protrusion is inserted through the positioning through hole.

[0019] Preferably, the sole further includes a subsole, which is attached to the lower surface of the second elastic layer, and the side of the subsole facing the ground is provided with a first anti-slip area and a second anti-slip area;

[0020] The first anti-slip zone is arranged corresponding to the outer forefoot of the human foot;

[0021] The second anti-slip zone is arranged corresponding to the inner side of the heel of the human foot.

[0022] Preferably, the first anti-slip area is provided with a first anti-slip group, which includes a plurality of first anti-slip protrusions in a straight line, and each of the first anti-slip protrusions gradually tilts backward from one end near the midsole to the corresponding other end;

[0023] The second anti-slip zone includes a front half zone and a rear half zone located behind the front half zone;

[0024] The front half of the region gradually curves upward from one end near the rear half of the region toward the corresponding other end;

[0025] The rear half of the region gradually curves upward from one end closer to the front half of the region toward the corresponding other end;

[0026] The front half area is provided with a second anti-slip group, which includes a plurality of straight-lined second anti-slip protrusions.

[0027] The rear half area is provided with a third anti-slip group, which includes a number of straight third anti-slip protrusions;

[0028] Each of the second anti-slip protrusions and each of the third anti-slip protrusions gradually slopes forward from one end near the midsole to the corresponding other end.

[0029] A running shoe includes an upper and a sole that are fixedly connected to each other, characterized in that: the sole adopts the aforementioned sole design.

[0030] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0031] First, by creating a notch on the outer side of the support plate, located at the junction of the forefoot and midfoot sections, the flexibility of the forefoot sole is improved, facilitating daily walking. Additionally, when athletes use a forefoot running style, increased forefoot flexibility also helps reduce the risk of injury during running. Furthermore, the midfoot plate, integrally connected to the inner side of the midfoot section, enhances the stability of the midfoot, further reducing the risk of injury during running and resulting in a relatively lower overall risk of injury.

[0032] Secondly, by integrally connecting the protrusion to the lower side of the foot plate, a second groove is opened at the lower end of the second elastic layer, and a positioning through hole is opened at the bottom of the second groove. The protrusion is inserted into the positioning through hole. This is beneficial to improve the connection performance between the second elastic layer and the support plate. At the same time, it also helps to assist in positioning the two during the bonding process of the support plate and the second elastic layer.

[0033] Third, the upper surface of the middle section gradually curves upward from the inside to the outside, and the upper surface of the rear section gradually curves upward from the inside to the outside. The upper surfaces of the middle section and the rear section together form an outer supporting surface. The upper surfaces of the middle section and the rear section transition smoothly. This helps to improve the stability of the midsection of the running shoe, prevents excessive twisting or pronation of the foot during running, and helps to stabilize the ankle.

[0034] Fourth, a first and a second anti-slip zone are set on the side of the sole facing the ground. The first anti-slip zone corresponds to the outer forefoot of the foot, and the second anti-slip zone corresponds to the inner heel of the foot. The positions of the first and second anti-slip zones are primarily based on the fact that the outer forefoot and inner heel of the foot are the main stress points during exercise, which helps to meet the stress requirements of running. By setting the first and second anti-slip zones on the sole, it is beneficial to better distribute the abrasion resistance and grip of the sole.

[0035] Fifth, each of the first anti-slip protrusions gradually slopes backward from one end near the bottom to the other, providing excellent grip. Each of the second and third anti-slip protrusions gradually slopes forward from one end near the bottom to the other, providing a strong anti-slip effect. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0054] like Figures 1-5 As shown in the figure, this embodiment provides a running shoe, including an upper (not shown in the figure) and a sole that are fixedly connected to each other. It should be noted that the connection structure between the upper and the sole is a conventional structure and is not the focus of this embodiment, so it will not be described in detail here.

[0055] For ease of description, in this embodiment, the side of the shoe facing the ground when it is in normal use is the lower side of each component, and the corresponding other side is the upper side of each component. The side of the shoe facing the toe is the front side of each component, and the corresponding other side is the rear side of each component. The side of a pair of shoes facing each other is the inner side of each component, and the corresponding other side is the outer side of each component.

[0056] The side of a person's feet facing each other is called the inner side of the foot, and the opposite side is called the outer side of the foot.

[0057] The human foot is divided into three parts from the outside to the inside: the outer side, the middle side, and the inner side. These three parts are arranged sequentially from the outside to the inside of the foot, and the middle side includes the second toe and the heel. The outer side includes the outer forefoot, the outer midfoot, and the outer heel. The middle side includes the middle forefoot, the middle midfoot, and the middle heel. The inner side includes the inner forefoot, the inner midfoot, and the inner heel.

[0058] The sole provided in this embodiment can also be sold independently; that is, this embodiment essentially provides another sole.

[0059] The sole provided in this embodiment includes a midsole 20, wherein a support plate 10 is embedded inside the midsole 20. The support plate 10 includes a front section 11, a middle section 12 and a rear section 13 that are integrally connected from front to back. The front section 11 is arranged corresponding to the outer part of the forefoot of the human foot, the middle section 12 is arranged corresponding to the outer part of the midfoot of the human foot, and the rear section 13 is arranged corresponding to the outer part of the heel of the human foot.

[0060] The midsole 20 can be a one-piece midsole or an adhesive midsole. In this embodiment, the midsole 20 includes a first elastic layer 30 and a second elastic layer 40 stacked sequentially from top to bottom. The lower side of the first elastic layer 30 has a first groove 31 at a position corresponding to the support plate 10. The support plate 10 is embedded in the first groove 31 of the first elastic layer 30, that is, the support plate 10 is sandwiched between the first groove 31 of the first elastic layer 30 and the second elastic layer 40. The support plate 10 is adhesively connected to the first groove 31 of the first elastic layer 30 and the second elastic layer 40, which helps to improve the integrity of the sole and thus improve the bending resistance of the sole.

[0061] In this embodiment, the first elastic layer 30 is made of high-resilience supercritical EVA foam material with a thickness of 18-25mm, providing cushioning and a soft feel upon contact with the foot. The second elastic layer 40 is made of a material with a higher hardness than the first elastic layer 30. Thus, the first elastic layer 30 can undergo elastic deformation under stress and return to its original shape after the force is released; while the second elastic layer 40 has a smaller elastic deformation than the first elastic layer 30, providing support to the first elastic layer 30.

[0062] It should be noted that the support plate 10 provided in this embodiment can also be sold independently or applied to other shoe soles. Therefore, this embodiment also provides a support plate 10.

[0063] The support plate 10 has a notch 14 on its outer side, which is located at the junction of the front section 11 and the middle section 12. This helps to improve the flexibility of the forefoot of the sole, making it easier to walk in daily life. At the same time, when athletes use the forefoot running style, increasing the flexibility of the forefoot bending also helps to reduce the risk of injury during running, making the risk of injury during running relatively low.

[0064] The medial side of the midsole 12 is integrally connected to a horizontally arranged midfoot plate 15, which corresponds to the middle part of the midfoot. The upper surface of the midfoot plate 15 is smoothly connected to the upper surface of the midsole 12. This helps improve the stability of the midfoot of the sole, reducing the risk of injury during running. Especially for runners with low arches or flat feet, this support plate 10 can effectively correct running posture and reduce excessive pronation caused by arch collapse.

[0065] Furthermore, a protrusion 17 is integrally connected to the lower side of the foot plate 15; a second groove 41 is provided at the lower end of the second elastic layer 40; a positioning through hole is provided at the bottom of the second groove 41, and the protrusion 14 is inserted into the positioning through hole. This is beneficial to improving the connection performance between the second elastic layer 40 and the support plate 10, and also helps to assist in positioning the support plate 10 and the second elastic layer 40 during the bonding process.

[0066] Furthermore, the upper surface of the middle section 12 gradually curves upward from the inside to the outside, and the outer upper surface of the rear section 13 gradually curves upward from the inside to the outside. The upper surfaces of the middle section 12 and the rear section 13 together form the outer circumferential support surface 18. The upper surfaces of the middle section 12 and the rear section 13 transition smoothly, which helps to improve the stability of the midsection of the running shoe, prevents excessive twisting or pronation of the foot during running, and helps to stabilize the ankle.

[0067] Furthermore, a protrusion 16 is provided on the lower outer side of the rear section 13, which helps to improve the support stability of the rear section 13 and also helps to prevent it from turning outward.

[0068] The sole also includes a lower sole 50, which is made of rubber. The lower sole 50 is attached to the lower surface of the second elastic layer 40. The side of the lower sole 50 facing the ground has a first anti-slip zone 51 and a second anti-slip zone 52. The first anti-slip zone 51 is arranged corresponding to the outer forefoot of the human foot; the second anti-slip zone 52 is arranged corresponding to the inner heel of the human foot. The positions of the first anti-slip zone 51 and the second anti-slip zone 52 are mainly based on the fact that the outer forefoot and the inner heel of the human foot are the main stress points during exercise.

[0069] In this embodiment, the first anti-slip area 51 is provided with a first anti-slip group, which includes a number of first anti-slip protrusions 53 in a straight line. Each first anti-slip protrusion 53 is arranged perpendicular to the front-back direction. Each first anti-slip protrusion 53 gradually tilts backward from one end near the midsole 20 to the corresponding other end. The backward tilting design of the first anti-slip protrusions 53 provides good grip.

[0070] As a preferred technical solution, the inclination angle of each first anti-slip protrusion 53 is 45°, and the distance between adjacent first anti-slip protrusions 53 is 5mm.

[0071] In this embodiment, the second anti-slip area 52 includes a front half and a rear half located behind the front half. The front half gradually curves upward from one end near the rear half to the corresponding other end. The rear half gradually curves upward from one end near the front half to the corresponding other end. The front half is provided with a second anti-slip group, which includes a plurality of straight second anti-slip protrusions 54. The rear half is provided with a third anti-slip group, which includes a plurality of straight third anti-slip protrusions 55. Each second anti-slip protrusion 54 and each third anti-slip protrusion 55 gradually tilts forward from one end near the midsole 20 to the corresponding other end.

[0072] Each of the second anti-slip protrusions 54 and each of the third anti-slip protrusions 55 is arranged perpendicular to the front-back direction. The second anti-slip protrusions 54 and the third anti-slip protrusions 55 are designed to be tilted forward, which has a strong anti-slip effect.

[0073] As a preferred technical solution, the inclination angle of each second anti-slip protrusion 54 is 45°, and the distance between adjacent second anti-slip protrusions 54 is 5mm.

[0074] As a preferred technical solution, the inclination angle of each third anti-slip protrusion 55 is 45°, and the distance between adjacent third anti-slip protrusions 55 is 5mm.

[0075] By setting a first anti-slip zone 51 and a second anti-slip zone 52 in the undersole 50, it is beneficial to better distribute the abrasion resistance and grip of the sole, while lightweight materials are used in other parts of the undersole 50 to improve cushioning or rebound performance.
