Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shoes, and in particular to a support piece, a shoe sole and sports shoes. BACKGROUND

[0002] For professional athletes who run for a long time, sports shoes that improve running economy (i.e., save energy consumption and improve efficiency) are essential. Although existing high-performance sports shoes can slightly improve running economy in each step, the cumulative benefits are very significant in long-distance running or short-time high-intensity training. In sports shoe technology, the design of adding a carbon plate or a support piece to the shoe sole has been proven to provide boost and speed-up effects for athletes with the help of camber guidance. However, most existing carbon plates or support pieces have a flat and single-layer design, which mainly relies on the properties of the carbon plate material itself to improve the propulsion. This design does not fully consider the rigidity and toughness requirements of runners at different speeds, as well as ergonomic factors, resulting in the need to optimize the impact of the carbon plate structure on running posture, the material on running experience, and the shock absorption performance during long-distance running. In addition, the existing carbon plate design lacks adaptability to individual differences of different runners (such as gait, weight, foot shape and running posture), which may affect the sports experience. SUMMARY

[0003] The utility model aims to overcome the above-mentioned defects or problems in the background art, and provide a support piece, a shoe sole and sports shoes, which integrate shock absorption and stable propulsion structure in the forefoot part to meet the comprehensive needs of runners for propulsion, comfort and stability, and improve the sports experience.

[0004] To achieve the above-mentioned purpose, the utility model each embodiment adopts the following technical solutions but not limited to the following solutions:

[0005] The first technical solution relates to a support piece for a shoe sole, comprising: a forefoot part divided into a main body and an outer ring, the outer ring being arranged around the main body and forming a hollow area between them; a heel part; and an arch part connecting the forefoot part and the heel part; the main body and the outer edge area are respectively extended and connected to the arch part, and the forefoot part is concave downward relative to the heel part to form a concave arc shape, and the concave depth of the outer ring is greater than or equal to the concave depth of the main body.

[0006] The second technical solution is based on the first technical solution, wherein the lowest point of the concave arc shape of the main body has a concave depth relative to the heel part of between 6mm and 16mm.

[0007] The third technical solution is based on the first technical solution, wherein the two side edges of the heel part are curved upward to form arc-shaped side walls.

[0008] The fourth technical solution is based on the third technical solution, wherein the heel part is provided with at least one hole structure, and the hole structure of the heel part is configured as one of no hole, single hole, double hole or triple hole.

[0009] The fifth technical solution is based on the fourth technical solution. In this solution, when the excavation structure is configured as a single hole, the heel part is provided with a central hole extending along its length direction, and the central hole is located in the middle area of ​​the heel part.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the diameter of the central hole gradually increases from near the arch of the foot to away from the arch of the foot.

[0011] The seventh technical solution is based on the sixth technical solution. In this solution, when the hole structure is configured as a double hole, the heel has two symmetrically distributed inner and outer holes, which are located on both sides of the central hole (without a hole) near the arch of the foot.

[0012] The eighth technical solution is based on the seventh technical solution, wherein when the excavation structure is configured with three holes, the rear part is provided with a central hole, an inner hole and an outer hole.

[0013] The ninth technical solution is based on any one of the first to eighth technical solutions, wherein a shoe sole includes an outsole and a midsole, the midsole includes the aforementioned support member and a foam body made of supercritical foam material, the foam body includes an upper sole and a lower sole fixed to each other, the support member is fixed between the upper sole and the lower sole, and the outsole is fixed to the lower sole.

[0014] The tenth technical solution is based on the ninth technical solution, wherein a sports shoe includes the aforementioned sole.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution and related embodiments, the forefoot consists of a main body and an outer ring. The outer ring surrounds the main body, forming a hollow area between them to provide stable propulsion for the runner, helping them maintain a stable stride and posture during running and avoiding energy waste caused by gait instability. The main body primarily provides overall stiffness. Through optimized stiffness design, the main body reduces joint energy consumption during running, improving running economy. The forefoot is concave towards the sole relative to the heel, and the concavity depth of the outer ring is greater than or equal to the concavity depth of the main body to accommodate runners at different paces.

[0017] In the second technical solution and related embodiments, the concave depth of the main body relative to the heel is 6mm to 16mm to match runners with different paces. The overall structural stress of the support component has been optimized through computer simulation to ensure good bending stiffness, provide shock absorption and stable transition functions, help reduce the impact on the feet during running, protect joints from injury, and enhance running stability and comfort.

[0018] In the third technical solution and related embodiments, the two sides of the heel bend upward to form an arc-shaped sidewall, which better fits the shape of the heel and enhances stability when wearing.

[0019] In the fourth technical solution and related embodiments, the heel of the support component is designed with a configurable perforated structure, providing a tailored optimal matching solution for runners with different characteristics (based on personal factors such as training volume, pace, and muscle strength) and running needs. Multiple configuration options for the heel, such as no perforation, single perforation, double perforation, or triple perforation, allow runners to choose the most suitable sole design according to their own needs, achieving personalized customization.

[0020] In the fifth technical solution and related embodiments, the support member, in a single-hole configuration, features a central hole design extending along its length in the heel area, striking a balance between stability and propulsion. This design not only reduces weight through the perforation but also enhances the heel's cushioning performance while ensuring sufficient stiffness to maintain good propulsion. This central hole layout allows for greater foot flexibility, providing runners with a comfortable and efficient running experience.

[0021] In the sixth technical solution and related embodiments, the central hole design of the heel of the support member has a diameter that gradually increases from near the arch of the foot to away from the arch of the foot. This not only optimizes the cushioning performance, but also provides a smoother transition and more even support for the foot during running, enhancing the comfort and stability of running.

[0022] In the seventh technical solution and related embodiments, in the dual-hole configuration, the heel is provided with two symmetrical inner and outer holes, which further reduces weight and improves propulsion, making it especially suitable for long-distance running to reduce foot fatigue, while enhancing stability through the sidewall design of the heel.

[0023] In the eighth technical solution and related embodiments, the three-hole configuration includes a center hole, an inner hole, and an outer hole, which further optimizes propulsion and flexibility. By reducing weight, the shoe becomes lighter, making it especially suitable for runners who pursue speed, although runners need to have a high level of skill and muscle strength to maintain stability through the high sidewall design.

[0024] In the ninth technical solution and related embodiments, the midsole uses supercritical foam material EVA. This material is lightweight and has excellent elasticity and cushioning performance, effectively reducing the impact of the ground on the foot during running, improving comfort and reducing the risk of sports injuries. Its tight integration with the support components allows the sole to provide sufficient support and effectively absorb shock, comprehensively improving the runner's athletic performance.

[0025] In the tenth technical solution and related embodiments, the sole combines high-performance support components with supercritical foam material to achieve a combination of lightweight, high elasticity and excellent cushioning performance, effectively improving wearing comfort and athletic performance.

Obviously, the described embodiments are preferred embodiments of the present utility model and should not be considered as excluding other embodiments.

It does not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific protection scope of this utility model.

[0041] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this utility model shall be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or components.

[0042] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0043] See Figures 1 to 9 ,like Figure 1 As shown, a support member 1, used for a shoe sole, includes a forefoot portion 11, a heel portion 13, and an arch portion 12, with the arch portion 12 connecting the forefoot portion 11 and the heel portion 13. The support member 1 is made of carbon fiber plate material.

[0044] The forefoot portion 11 is divided into a main body 110 and an outer ring 111. The outer ring 111 surrounds the main body 110, and a hollow area 112 is formed between the two. The main body 110 and the outer ring 111 extend and connect to the arch portion 12. Specifically, the hollow area 112 is U-shaped or arc-shaped, and its opening faces the arch portion 12.

[0045] The forefoot portion 11 is concave towards the sole relative to the heel portion 13, forming a concave arc. The concave depth of the outer ring 111 is greater than or equal to the concave depth of the main body 110. The lowest point of the concave arc of the main body 110 is between 6mm and 16mm deep relative to the heel portion 13, meaning the landing difference between the main body 110 and the heel portion 13 is between 6mm and 16mm.

[0046] Based on the depth of the recess of the main body 110 and the outer ring 111 relative to the heel portion 13, there are two embodiments as follows.

[0047] Example 1

[0048] like Figure 2 As shown, the concave depth of the main body 110 relative to the heel 13 is 6mm, and the concave depth of the outer ring 111 relative to the heel 13 is greater than the concave depth of the main body 110 relative to the heel 13. That is, there is a drop between the main body 110 and the outer ring 111 relative to the heel 13, so the cushioning travel distance after the runner lands will be relatively large.

[0049] Example 2

[0050] like Figure 3 As shown, the concave depth of the main body 110 relative to the heel 13 is 16mm, and the concave depth of the outer ring 111 relative to the heel 13 is equal to the concave depth of the main body 110 relative to the heel 13, which is suitable for full-foot strike when running.

[0051] To meet the needs of different paces, support component 1 offers varying structural rigidity and toughness, as well as bending stiffness, to satisfy the propulsion and stability requirements of different runners. The overall structural stress of support component 1 has been optimized through computer simulation to ensure good bending stiffness, providing shock absorption and stable transition functions. This helps reduce the impact on the feet during running, protects joints from injury, and enhances running stability and comfort.

[0052] Heel part 13, such as Figure 1 As shown, its two sides bend upward to form an arc-shaped sidewall 130 to improve the stability of the sole.

[0053] like Figures 4 to 7As shown, the heel section 13 has at least one perforated structure, which can be configured as no perforation, single perforation, double perforation, or triple perforation. The heel section 13 of this support member 1 features a configurable perforated structure, providing a tailored optimal fit for runners with different characteristics (based on individual factors such as training volume, pace, and muscle strength) and running needs. The multiple configuration options for the heel section 13, including no perforation, single perforation, double perforation, or triple perforation, allow runners to choose the most suitable sole design according to their own needs, achieving personalized customization.

[0054] Example 3

[0055] like Figure 4 As shown, when the perforated structure of the heel section 13 is without perforations, the perforation-free design provides maximum stiffness, which helps improve the stability of the shoe, especially during high-speed running or turning, allowing for better control of foot movement, reducing unnecessary deformation, and providing maximum propulsion assistance. However, this design may sacrifice some propulsion and flexibility, as the stiffer carbon plate may restrict the natural movement of the foot.

[0056] Example 4

[0057] like Figure 5 As shown, when the perforated structure is configured as a single hole, the heel portion 13 has a central hole 131 extending along its length. The central hole 131 is located in the middle region of the heel portion 13, and its diameter gradually increases from near the arch portion 12 to away from the arch portion 12. In this embodiment, with the support member 1 in a single-hole configuration, the heel portion 13 adopts a design with a central hole 131 extending along its length, finding a balance between stability and propulsion. This design not only reduces weight by perforating, but also enhances the cushioning performance of the heel, while ensuring sufficient stiffness to maintain good propulsion. This central hole 131 layout allows the foot to gain more flexibility, providing runners with a comfortable and efficient running experience. The design of the central hole 131 in the heel portion 13 of the support member 1, with its diameter gradually increasing from near the arch portion 12 to away from the arch portion 12, not only optimizes cushioning performance, but also provides a smoother transition and more even support for the foot during running, enhancing running comfort and stability.

[0058] Example 5

[0059] like Figure 6 As shown, when the hole structure is configured with two holes, the heel portion 13 has two symmetrically distributed inner holes 132 and outer holes 133, located on both sides of the un-holeed central hole 131 near the arch portion 12. In this embodiment, with the two-hole configuration, the heel portion 13 has two symmetrical inner holes 132 and outer holes 133, further reducing weight and improving propulsion, making it especially suitable for long-distance running to reduce foot fatigue. At the same time, the sidewall design of the heel portion 13 enhances stability.

[0060] Example 6

[0061] like Figure 7 As shown, when the perforation structure is a three-hole configuration, the heel portion 13 has a central hole 131, an inner hole 132, and an outer hole 133. In this embodiment, the three-hole configuration includes a central hole 131, an inner hole 132, and an outer hole 133, further optimizing propulsion and flexibility. By reducing weight, the shoe becomes lighter, making it especially suitable for runners who pursue speed, although runners need a high level of technique and muscle strength to maintain stability through the high sidewall design.

[0062] The perforated structure in Examples 4 to 6 effectively reduces the weight of the sole, lessening the burden on runners and improving ease and efficiency during exercise. For runners requiring stronger support, the perforated structure in the heel 13 can be adjusted to reduce the number of perforations or optimize their placement, providing additional stability and ensuring safety and control during running. While providing additional propulsion, the designed perforation scheme ensures that the stability of the sole remains unaffected, helping runners further improve their athletic performance.

[0063] In existing technologies, while different perforation designs for support plates each consider runners' needs from three key perspectives—lightweighting, stability, and propulsion—they lack in-depth discussions on the balance and comprehensive consideration between these designs. Each design often focuses on optimizing a single dimension, making it difficult to fully address the diverse functional needs of different runners. This may lead to progress in some areas while compromising or falling short in others. For example, some perforation designs may sacrifice stability and comfort to improve lightweighting or propulsion, thus affecting the runner's overall performance.

[0064] This application proposes a perforated structure design aimed at optimizing the stability, propulsion, and lightweight characteristics of running shoes by adjusting the perforation layout, thereby improving the wearer's comfort, ease of use, and safety. To achieve this goal, this application employs finite element simulation technology to conduct a detailed analysis of the specific performance parameters of different perforation designs, including changes in the stiffness of the carbon plate, optimization of weight distribution, and their impact on foot biomechanics.

[0065] Specifically, the no-hole design offers maximum stability and propulsion, but sacrifices some comfort, potentially making it less suitable for runners seeking extreme lightness and comfort. Single-hole and double-hole designs strike a better balance between stability and propulsion while also improving comfort to some extent, making them more suitable for the daily training needs of most runners. The triple-hole design focuses on lightweighting, aiming to make running easier and more enjoyable by reducing the shoe's weight. However, this design requires rigorous finite element simulation to ensure its safety, avoiding excessive perforations that could negatively impact the strength of the carbon fiber plate structure.

[0066] Based on this simulation data, the location, size, and number of perforations can be precisely adjusted to achieve the optimal performance balance. This not only meets runners' diverse performance needs for running shoes but also ensures that the carbon plate design performs excellently in multiple dimensions, including lightweight, stability, and propulsion, providing runners with a superior running experience.

[0067] In this embodiment, the forefoot portion 11 of the support member 1 consists of a main body 110 and an outer ring 111. The outer ring 111 surrounds the main body 110, forming a hollow area 112 between them, providing stable propulsion for the runner and helping the runner maintain a stable stride and posture during running, avoiding energy waste caused by unstable gait. The main body 110 mainly undertakes the task of providing overall rigidity. Through optimized rigidity design, the main body 110 reduces the energy consumption of joints during running, improving running economy. The forefoot portion 11 is concave towards the sole relative to the heel portion 13, and the concave depth of the outer ring 111 is greater than or equal to the concave depth of the main body 110 to match runners with different paces.

[0068] A type of shoe sole, such as Figure 8 and Figure 9 As shown, it includes an outsole 4 and a midsole. The midsole includes a support member 1 as described above, and a foam body made of supercritical foam material. The foam body includes an upper sole 2 and a lower sole 3 fixedly connected to each other. The support member 1 is fixed between the upper sole 2 and the lower sole 3, and the outsole 4 is fixedly connected to the lower sole 3. In this embodiment, the midsole uses supercritical foam material EVA. This material is lightweight and has excellent elasticity and shock absorption performance, effectively reducing the impact force of the ground on the foot during running, improving comfort and reducing the risk of sports injuries. The tight combination with the support member 1 allows the sole to provide sufficient support and effectively absorb shock, comprehensively improving the runner's athletic performance.

[0069] An athletic shoe includes the aforementioned sole. In this embodiment, the sole combines a high-performance support member 1 with a supercritical foam material to achieve a combination of lightweight, high elasticity, and excellent cushioning performance, effectively improving wearing comfort and athletic performance.

[0070] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
