Description
Technical Field
[0001] The utility model relates to the field of running shoes, in particular to a novel sole and its running shoes. Background Technique
[0002] In recent years, there has been a wave of national fitness campaigns across the country. People of all ages and genders actively participate in fitness exercises to achieve the goal of strengthening the body. Running, as the simplest and most basic item in fitness exercises, is deeply favored by people. Most people will choose running for fitness. At this time, running shoes, as essential equipment for running, are very important for runners. If the running shoes chosen by runners are not suitable, it is easy to cause runners to get injured during the running process.
[0003] In recent years, with the continuous progress of material science and technology, carbon plate materials and technologies have been widely applied and developed. For example, technological innovations in aviation, automobiles, sports equipment, semiconductors, etc. have provided more possibilities and solutions for the application fields of carbon plate technology. With the intensification of competition and the diversification of market demands, consumers are becoming more and more interested in innovative, highly functional, and good-experience products. In the field of footwear products, carbon plates, as an important part of enhancing stability and security, have an increasing demand for innovation and technological breakthroughs.
[0004] Carbon fiber soles have the advantages of light weight, greater toughness, better elasticity, and good fatigue resistance. With the blessing of such high-tech, carbon plate shoes have also become the leaders among running shoes and have also become one of the functions pursued by many professional enthusiasts. However, in the existing technology, the carbon fiber soles produced show high rigidity characteristics on both sides and do not have the comfort of soft elasticity.
[0005] During the running process, runners need stable support to maintain balance and avoid accidents such as sprained ankles. Long-term running will cause fatigue and damage to the feet. The light weight characteristic of the carbon plate can reduce the weight of the shoes, reduce the foot burden of runners, and reduce the sense of fatigue.
[0006] Existing carbon plate shoes have some disadvantages in the breathable design of the insole, mainly including the following points:
[0007] 1. High hardness: Due to the high strength and high rigidity characteristics of the carbon plate material, the hardness of the shoes is relatively high. Although this hardness can provide stable support, for novice runners and ordinary running enthusiasts, it may not be very adaptable. Because the design with high carbon plate strength will force the forefoot to land, which increases the pressure on the calf, Achilles tendon, and ankle, making the calf prone to fatigue after running.
[0008] 2. Control Difficulty: The midsole thickness addition of carbon plate shoes may bring problems of difficult control during running. Especially for beginners or runners with unskilled techniques, there may be a risk of ankle sprains. This is because carbon plate shoes are relatively hard, reducing the natural feedback of the feet, making it necessary for runners to have higher skills to adapt.
[0009] 3. Poor Durability: Carbon plate shoes are not very durable. Due to the addition of carbon plates, the shock absorption and flexibility of the shoes themselves will be greatly restricted. Long-term excessive extrusion is likely to cause deformation of the carbon plates, not only wearing out the high-strength rebound of the carbon plates, but seriously may also lead to fractures. This poor durability makes the service life of carbon plate shoes relatively short.
[0010] 4. Limited Shock Absorption Performance: After choosing carbon plates, the overall shock absorption performance of the soles will drop significantly. Although some new carbon plate shoes have been strengthened in shock absorption, compared with traditional running shoes, their shock absorption performance is still limited, which may make runners feel uncomfortable during long-term or high-intensity running.
[0011] 5. Poor Adaptability: The hardness and design of carbon plate shoes make their adaptability poor. Due to the inability to adapt well to the foot shape, wearing such shoes for a long time is likely to cause foot discomfort and even lead to foot diseases. In addition, carbon plate shoes are generally relatively narrow and cannot adapt well to all foot shapes, which may lead to incorrect foot postures and problems such as hallux valgus and flat feet.
[0012] Therefore, designing a running shoe with reduced hardness, strong adaptability, good durability, and good shock absorption performance has become a technical problem to be solved by this utility model. Summary of the Invention
[0013] The technical problem to be solved by this utility model is to provide a novel sole and its running shoe with a simple structure, which can reduce hardness, improve adaptability and shock absorption performance, and reduce the risk of ankle sprains.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0039] Embodiment 1
[0040] As Figures 1 to 4 shown, a new type of sole 100 includes an upper foaming layer 1, a carbon plate member 2, a lower foaming layer 3 and a outsole 4.
[0041] The upper foaming layer 1 is made of supercritical EVA foaming material, and a plurality of ventilation holes 11 are respectively provided at the inner and outer edges. Preferably, three ventilation holes 11 are respectively provided at the inner and outer edges. The height direction of the heel part of the upper foaming layer 1 is designed in a corrugated manner, and a notch 12 is provided at the outer bottom edge of the heel part; the average thickness of the forefoot part of the upper foaming layer 1 is lower than the average thickness of the heel part, and the height difference does not exceed 1 cm. Preferably, the average thickness of the forefoot part of the upper foaming layer 1 is 3 cm, and the average thickness of the heel part is 2.5 cm. Due to the different foaming amounts of the materials in the forefoot part and the heel part, the comfort of the forefoot part is maintained. According to the ergonomic force application standard, the center of gravity of the force application point of most people is behind, so the heel part is closer to the carbon plate member 2.
[0042] The carbon plate member 2 is disposed below the upper foaming layer 1 and is made of nylon material. It has strength and stiffness while maintaining light weight. This plate plays a role of support and stability in the midsole, ensuring that the shoes maintain their shape and structural integrity during long-term wear or high-intensity activities. The carbon plate member 2 made of nylon material reduces the hardness of the material and increases flexibility while maintaining sufficient strength and rigidity, thereby reducing unnecessary pressure on the feet and legs. And a smaller carbon content makes it more adaptable, helping to effectively transfer the shock absorption effect of the upper foaming layer 1 to the lower foaming layer 3 and realizing efficient energy conversion; it can undergo reasonable deformation when compressed, thereby absorbing impact energy; on the upper surface of the carbon plate member 2, a raised first reinforcing rib 21 is provided on each of the inner and outer sides along the length direction. A raised second reinforcing rib 22 is provided between the two first reinforcing ribs 21 and located at the forefoot. A number of polygonal concave-convex reinforcing structures 23 are provided between the heel and the arch. The first reinforcing rib 21, the second reinforcing rib 22 and the reinforcing structure 23 improve the stability of the carbon plate member 2 and increase the support for the sole. On the inner and outer edges of the forefoot and heel of the carbon plate member 2, an extension piece 24 extends outward. Preferably, the extension piece 24 extends outward by 0.5 cm. The extension piece 24 on the outer side of the heel extends outward by 1.8 cm and is inclined at 45°, corresponding to wrapping around the notch 12 of the upper foaming layer 1. Grooves 25 are provided on the lower surface of the carbon plate member 2 corresponding to the positions of the first reinforcing rib 21 and the second reinforcing rib 22.
[0043] The lower foaming layer 3 is made of supercritical EVA foaming material and is disposed below the carbon plate member 2. On its upper surface, ridges 31 are provided corresponding to the positions of the first reinforcing rib 21 and the second reinforcing rib 22. The ridges 31 are correspondingly disposed in the grooves 25 on the lower surface of the carbon plate member 2. By providing the ridges 31 on the lower foaming layer 3, it can be used to strengthen and stabilize the support of the carbon plate member 2, making the lower foaming layer 3 fit more closely with the carbon plate member 2. A through groove 32 is provided on the lower foaming layer 3 corresponding to the position of the reinforcing structure 23 of the carbon plate member 2, and the reinforcing structure 23 is exactly correspondingly disposed in the through groove 32.
[0044] The outsole 4 is made of CPU material and is disposed below the lower foaming layer 3. Anti-slip patterns (not shown) are provided on the lower surface of the outsole 4 for anti-slip of the sole 100.
[0045] Supercritical Foaming EVA Technology: Memory physical materials have a certain memory ability and can return to their original state after being stressed, providing good shock absorption for the wearer. The supercritical foaming technology makes the EVA material lighter while maintaining good elasticity and durability. With a closed-cell structure, the EVA material has the characteristics of anti-aging, odor resistance, non-toxicity, soft shock absorption and biodegradability. As the upper and lower foaming layers of the midsole, it can effectively absorb the ground reaction force, providing layer-by-layer protection for the feet, with good softness and elasticity, and also very good surface gloss and chemical stability.
[0046] Working Principle:
[0047] Pressing Stage: When the runner steps down, the first part to come into contact is the upper foaming layer 1. This material can quickly respond to the pressing, start to deform and absorb the impact force. As the pressing deepens, the carbon plate part 2 begins to play a role. Due to its high rigidity and stability, the carbon plate part 2 can maintain the shape of the sole 100 and prevent it from bending excessively, thus providing stable support for the runner. The lower foaming layer 3 further absorbs the remaining impact force and forms a buffer system together with the upper foaming layer, effectively reducing the risk of foot injury.
[0048] Rebounding Stage: After the pressing, when the foot leaves the ground, the materials in the midsole start to quickly return to their original shape. The memory physical supercritical foaming EVA of the upper foaming layer 1 and the lower foaming layer 3 can quickly rebound, release the stored energy, and push the runner forward. The carbon plate part 2 also plays a key role in the rebounding stage. Due to its excellent rigidity and resilience, the carbon plate part 2 can help the sole 100 quickly return to its shape, providing continuous power for the runner.
[0049] Force Support: During the whole running process, the first reinforcing rib 21, the second reinforcing rib 22 and the reinforcing structure 23 of the carbon plate part 2 provide stable support for the runner. Whether running straight or turning, the carbon plate can maintain the stability of the sole, preventing the foot from twisting or deforming excessively. At the same time, the memory physical supercritical foaming EVA of the upper foaming layer 1 and the lower foaming layer 3 also provides additional support and stability for the runner through its structure and material characteristics.
[0050] Foot Sole Wrapping: The extension piece 24 at the heel part of the carbon plate part 2 wraps around the upper foaming layer 1, and at the same time gives a supporting force to the heel part, providing a good sense of foot sole wrapping for the runner. This sense of wrapping can ensure that the running shoes fit closely with the feet, reduce friction and sliding, and improve the comfort and stability of running. Especially when the runner is doing high-intensity or long-distance running, a good sense of foot sole wrapping can reduce foot fatigue and discomfort, and help the runner better maintain their state.
[0051] The utility model designs ventilation holes 11 on the upper foaming layer 1, which helps with overall exhaust and sweat discharge, increasing the foot feeling and overall comfort of the sole 100; and the height direction of the heel part of the upper foaming layer 1 is designed in a corrugated pattern, which can effectively slow down material attenuation, reduce wrinkle generation, and extend the service life. The carbon plate member 2 is made of nylon material, which has strength and stiffness while maintaining light weight, plays a supporting and stabilizing role in the midsole, can ensure the shape and structural integrity of the sole 100 during long-term wearing or high-intensity activities, and with a smaller carbon content, it has more adaptability, helps to effectively transfer the upper shock absorption effect to the lower layer, and realizes efficient energy conversion; and the first reinforcing rib 21, the second reinforcing rib 22 and the reinforcing structure 23 are designed on the carbon plate member 2, which improves the stability of the carbon plate member 2 and increases the support for the sole of the foot; by setting the extension piece 24 on the carbon plate member 2, better wrapping and support can be provided, reducing the risk of ankle sprain. By setting the convex strips 31 on the lower foaming layer 3, it can be used to strengthen and stabilize the support of the carbon plate member 2, making the lower foaming layer 3 fit better with the carbon plate member 2. The utility model is a new type of sole with a simple structure, which can reduce hardness, improve adaptability and shock absorption performance, and reduce the risk of ankle sprain, meeting the diverse needs of consumers in terms of comfort, support, shock absorption performance and other functions, and improving the wearing experience.
[0052] Embodiment 2
[0053] As Figure 5 As shown, a new type of running shoe includes a shoe upper 200 and the new type of sole 100 described in the above Embodiment 1. The shoe upper 200 is disposed on the sole 100. This embodiment is a new type of running shoe with a simple structure, which can reduce hardness, improve adaptability and shock absorption performance, and reduce the risk of ankle sprain, meeting the diverse needs of consumers in terms of comfort, support, shock absorption performance and other functions, and improving the wearing experience.
[0054] A new type of running shoe of the present utility model can provide more sensitive feedback and more uniform support during the landing and take-off process of each step of the runner, thereby effectively improving running efficiency and comfort. Omnidirectional energy feedback is achieved. At the moment when the runner's foot touches the ground, the running shoe of the present utility model can quickly convert the impact force into elastic potential energy and release it when the runner takes off, providing an additional driving force for the runner. This energy feedback mechanism not only improves the economy of running but also reduces the energy consumption of the runner. By precisely controlling the slope difference between the forefoot and the heel, the running shoe can better adapt to the running needs of different runners. A reasonable slope difference design can make the runner more labor-saving during running and improve running efficiency. The present utility model has a lighter weight and higher strength. This light-weight and high-strength feature enables the runner to feel a more light and flexible experience when wearing the running shoe, while ensuring the durability and service life of the running shoe. The present utility model effectively improves the breathability and comfort of the running shoe by using breathable materials and a reasonable ventilation structure, accelerates the air circulation inside the shoe, reduces the accumulation of foot sweat, and reduces the feeling of foot dampness and stuffiness. The present utility model also has an adaptive performance and can automatically adjust the support strength and stiffness according to factors such as the runner's weight, stride length, and running posture, can adapt to the running styles and habits of different runners, and provide more personalized support and protection. This personalized support design can ensure that the runner obtains the best support experience during running and reduces sports injuries caused by improper support. While ensuring the stability of the running shoe, it provides a more elastic and plastic support. At the same time, this structure can also effectively release kinetic energy recovery and improve the efficiency and performance of running.
[0055] Although the specific implementation manners of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present utility model should all be covered within the scope protected by the claims of the present utility model.
