Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and more specifically to a sports running shoe. Background Technology

[0002] In recent years, support plate technology (such as nylon plates, carbon fiber plates, etc.) has been widely used in running shoes, especially in competitive running shoes. This technology embeds one or more support plates into the midsole material of the running shoe (such as PEBAX, EVA, or PU foam materials). During running, when the foot pushes off the ground, the support plate deforms and stores energy, then releases the energy through rebound, thus generating a "boost" or "propulsion" effect, effectively reducing energy loss and improving running economy. However, while adding support plates to the sole of running shoes enhances propulsion, it also increases the instability of the sole if the shoe is not properly controlled.

[0003] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0004] The purpose of this invention is to provide a running shoe that reduces rolling resistance, improves force transmission efficiency, and has good stability.

[0005] To achieve the above objectives, the solution of this utility model is: a running shoe, comprising a sole and an upper connected to the sole, the sole comprising an outsole and a midsole composited on the outsole, a support plate embedded in the midsole, the support plate having a harder hardness than the midsole, the support plate being arranged from front to back as a forefoot portion, a midsection portion and a heel portion, the forefoot portion having a forefoot widening portion extending outward from the outer side of the metatarsal region of the human foot, the midsection portion having a midsection widening portion extending inward from the inner side of the heel portion, the midsection widening portion being an arc-shaped portion arranged curving upward from the outside to the inside.

[0006] The support plate is provided with a first forked groove between the big toe and the second toe of the human foot. The front side of the first forked groove extends to the front end of the support plate, and the rear side of the first forked groove extends to the metatarsophalangeal region of the human foot of the support plate; and / or, the heel portion of the support plate is provided with a second forked groove, and the support plate forms two heel support arms through the second forked groove.

[0007] The widened mid-waist section extends in the front-to-back direction, with the front portion of the widened mid-waist section extending to the middle position corresponding to the sole, and the rear portion of the widened mid-waist section extending to the vicinity of the heel.

[0008] The widened section in the middle waist is adapted to the arch position of the human foot.

[0009] The forefoot widening portion extends in the front-to-back direction, and the front part of the forefoot widening portion extends to the fourth toe position of the forefoot, and the front part of the forefoot widening portion and the fourth toe position of the forefoot connect with each other, and the rear part of the forefoot widening portion extends to the mid-waist.

[0010] The outsole has several perforations, the midsole is a popcorn midsole or an EVA midsole, and the outsole has anti-slip parts formed corresponding to the positions of the perforations for the corresponding parts of the midsole to be exposed.

[0011] The bottom of the shoe sole has an upward recessed area in the middle, and the recessed area has a crescent-shaped arch hole.

[0012] The shoe upper has two shoe wing positions respectively with shoelace hole groups, each of the shoelace hole groups includes a number of shoelace holes, and a protective film is respectively provided on the upper side of each shoe wing corresponding to the position of each shoelace hole, and both protective films are transparent films.

[0013] The two sides of the shoe wing of the shoe upper have extension pressing parts that extend towards each other, and both extension pressing parts are located above the shoe tongue of the shoe upper.

[0014] The upper sides of the two extended pressing parts are respectively coated with anti-wrinkle films, both of which are arranged in the front-to-back direction, and both of which are PE or TPC films.

[0015] By adopting the above structure, this utility model has the following beneficial effects: 1. By incorporating a widened forefoot section on the outer side of the support plate and a widened midfoot section on the inner side, the widened midfoot section enhances the stability and medial support of the running shoe. This effectively reduces the outward pronation angle and speed of the runner's ankle during landing, thus lessening the load on the ankle joint. The widened forefoot section also improves flexural stiffness, enhancing propulsion during the push-off phase. The diagonal arrangement of the forefoot and midfoot widened sections helps the runner coordinate the transmission path of the vertical ground reaction force with the dynamic changes in the center of pressure during ground contact, reducing rolling resistance and improving force transmission efficiency. In other words, the widened outer forefoot and inner heel sections prevent the shoe from overprone, resulting in a more centered force line. 2. The popcorn midsole design gives the sole of this invention excellent elasticity and cushioning performance, effectively absorbing impact during exercise and providing good shock absorption protection for the feet; while the perforated design on the outsole allows corresponding parts of the midsole to be exposed to form anti-slip areas, increasing the friction between the sole and the ground and improving the grip of the running shoe, while also reducing the overall weight of the sole.

[0016] 3. A transparent film is provided on the upper side of the shoe wing corresponding to the position of each shoelace eyelet. This is to prevent the shoe upper from tearing at the position corresponding to the shoelace eyelets when the shoelaces are pulled, especially when the shoe upper is made of mesh.

Detailed Implementation

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] A type of running shoe, such as Figures 1-5 As shown, the shoe includes an upper 1 and a sole 2. The upper 1 is connected to the sole 2 in a conventional manner. The sole 2 includes an outsole 3 and a midsole 4 bonded to the outsole 3. The outsole 3 and the midsole 4 are connected in a conventional manner, for example, by means of adhesive. A support plate 5 is conventionally embedded in the midsole 4.

[0025] Furthermore, the elasticity of the midsole 4 is greater than that of the support 5, that is, the hardness of the midsole 4 is less than that of the support plate 5. In this embodiment, the support plate 5 can be a conventional shoe material such as a nylon plate, carbon plate, or TPU plate, the midsole 4 is a conventional popcorn midsole or EVA midsole, and the outsole 2 is a conventional rubber outsole.

[0026] Furthermore, the aforementioned support plate 5 is configured from front to back as a forefoot portion 21, a midfoot portion 22, and a heel portion 23. The forefoot portion 23 corresponds to the forefoot position of the human foot, the midfoot portion 22 corresponds to the arch position of the human foot, and the heel portion 23 corresponds to the heel position of the human foot. It is worth mentioning that the positional definitions of the forefoot portion 21, midfoot portion 22, and heel portion 23 in this utility model also apply to the outsole 3 and the midsole 4.

[0027] For ease of description, the reference orientation is taken as the state of normal use of this utility model, with the side of the shoe with the sole facing the toe as the front and the corresponding side as the back, and the side of the two shoe bodies facing each other as the inside and the corresponding side as the outside.

[0028] In the aforementioned support plate 5, the forefoot portion 11 extends outward from the outer side of the metatarsal region of the human foot, with a forefoot widening portion 51. The mid-waist portion 12 extends inward from the inner side of the heel portion 13, with a mid-waist widening portion 52. The mid-waist widening portion 52 is an arc-shaped portion that curves upward from the outside to the inside, and the arc-shaped portion is an upwardly convex arc-shaped structure. In this way, the forefoot widening portion 51 and the mid-waist widening portion 52 are both widened on the basis of the conventional support plate 5, and the two are arranged diagonally to make the two work together.

[0029] Furthermore, the aforementioned forefoot widening portion 51 extends in the front-to-back direction. Its front part extends to the position corresponding to the fourth toe of the forefoot of the support plate 5, naturally connecting with the side of that position. The rear part extends backward to a position near the midsection 22, naturally connecting with the corresponding position. In this way, the widened support in the forefoot area can cover the key areas from the toe force point to the forefoot transition zone, which is beneficial to improving bending stiffness and enhancing the propulsive effect during the push-off phase. Here, the fourth toe position of the forefoot portion 21 refers to the position of the little toe. Preferably, the outer contour of the forefoot widening portion 51 is an outwardly convex arc shape, that is, the outer contour of the forefoot widening portion 51 is adapted to the outer side of the metatarsal area of ​​the human foot, which can better fit the force area on the outer side of the forefoot and improve the support stability during push-off.

[0030] Furthermore, the aforementioned mid-waist widening portion 52 extends in the front-to-back direction, with its front portion extending to the middle of the sole 2 and its rear portion extending to near the heel 23. Preferably, the mid-waist widening portion 52 is adapted to the arch position of the human foot, thus conforming to the physiological curve of the inner side of the arch. More preferably, the inner side of the mid-waist widening portion 52 can also extend with a sidewall 521 that curves upward from the outside to the inside, and the mid-waist widening portion 52 is arched. This sidewall 521 can further wrap around the inner side of the arch, enhance lateral support for the arch, reduce excessive arch collapse during exercise, and improve the overall stability of the running shoe. In this way, the design of the mid-waist widening portion 52 helps to improve the stability and medial support of the running shoe, effectively reducing the ankle eversion angle and eversion speed during the landing phase, and reducing the ankle joint load.

[0031] In this embodiment, the diagonal arrangement of the forefoot widening portion 51 and the midfoot widening portion 52 allows them to work together to ensure that the transmission path of the vertical ground reaction force is well coordinated with the dynamic changes of the pressure center during the ground contact phase. That is, when the outer side of the heel contacts the ground first, the midfoot widening portion 52 and its structure reduce the ankle eversion angle and guide the pressure center to smoothly transition along the central axis of the midsole. As the body's center of gravity shifts forward, the forefoot widening portion 51 can enhance lateral support, reduce energy loss caused by force line deviation, and improve force transmission efficiency.

[0032] Furthermore, the aforementioned support plate 5 is provided with a first forked groove 61 between the big toe and the second toe (i.e., the index toe) of the human foot. The front side of the first forked groove 61 extends to the front end of the support plate 5, and the rear side extends to the metatarsophalangeal region of the human foot. This design can adapt to the natural opening and force exertion of the toes, provide better flexibility when the forefoot is bent, and avoid excessive restriction of toe movement by the support plate.

[0033] Furthermore, the heel portion 23 of the support plate 5 is provided with a second fork groove 62. The support plate 5 forms two heel support arms through the second fork groove 62, so that when running and landing, it can generate a certain deformation buffer according to the force on the heel and disperse the impact force on the heel.

[0034] In this way, the design of the first and second fork slots enhances the flexibility and cushioning performance of the support plate in key areas while ensuring the overall support strength of the support plate. This allows the running shoe to provide effective propulsion and support while adapting to the natural movement trajectory of the foot.

[0035] Furthermore, the aforementioned outsole 3 has several perforations 31, which are respectively distributed on the forefoot, midfoot, and heel of the outsole 3. Preferably, each perforation 31 is a square hole. In this embodiment, the popcorn midsole is used as an example for explanation. The bottom surface of the outsole 3 has anti-slip parts corresponding to the positions of each perforation 31. That is, each anti-slip part is the position exposed from the corresponding perforation 31. Since the popcorn midsole itself has good elasticity and cushioning performance, but is not wear-resistant, the design of the perforations allows the midsole to partially contact the ground, which increases grip performance and anti-slip performance, and ensures safety during sports.

[0036] Furthermore, the bottom of the aforementioned sole 2 has an upward recessed area in the middle, which extends through the outsole 3 and extends along the upper side of the midsole 4. The recessed area of ​​the sole 2 has an arch support hole 7, which is crescent-shaped. This reduces the weight of the sole 2 and enhances the elastic deformation capability of the midsole in the arch area, better adapting to the dynamic changes of the arch and improving the fit.

[0037] Furthermore, in this embodiment, the shoe upper 1 is made of conventional mesh fabric and the shoe upper is provided with shoelaces in a conventional manner.

[0038] The two shoe wings of the shoe upper 1 are respectively provided with shoelace eyelet groups. Each shoelace eyelet group includes a number of shoelace holes 81. The upper side of each shoe wing is provided with a protective film 82 corresponding to the position of each shoelace hole 81 in a conventional manner, such as by composite, adhesive or hot pressing. Preferably, each protective film 82 is a transparent film, and each protective film 82 is a PE or TPC film. In this way, without affecting the appearance of the shoe upper, the strength of the shoe upper around the shoelace holes can be effectively enhanced, preventing the shoe upper from tearing due to excessive tension when tightening the shoelaces, and extending the service life of the running shoes.

[0039] Preferably, one side of the shoe wing of the shoe upper 1 extends with an extension pressing part 11 in a direction close to the middle of the shoe tongue, so that the extension pressing part 11 is located above the shoe tongue of the shoe upper 1. Preferably, the two sides of the shoe wing of the shoe upper 1 extend with extension pressing parts 11 in a direction close to each other, and both extension pressing parts 11 are located above the shoe tongue of the shoe upper 1, so that the extension pressing parts 11 can exert a certain downward pressure on the shoe tongue after the shoelaces are tightened, preventing the shoe tongue from shifting during exercise, and also enhancing the fit between the shoe upper and the foot, and improving the wrapping feeling. Preferably, the upper sides of the two extended pressing parts 11 are respectively provided with anti-wrinkle films 12 in a conventional manner. Both anti-wrinkle films are arranged in the front-back direction, and both anti-wrinkle films are PE or TPC films. PE or TPC films have good wear resistance and toughness, which can further protect the extended pressing parts and prevent damage due to friction or collision during movement. At the same time, they can also maintain the shape stability of the extended pressing parts and ensure their long-term effective function. The anti-wrinkle film 12 can be a non-transparent film to increase aesthetics.

[0040] This utility model relates to a running shoe that incorporates a support plate with a widened forefoot and midfoot section embedded in the midsole, along with the aforementioned upper. This design enhances propulsion and stability while incorporating a lightweight arch support structure and a perforated anti-slip cushioning design. This allows the running shoe to adapt to the natural movement trajectory of the foot, and the protective and wrinkle-resistant layers enhance the durability of the upper, achieving a balance between functionality and practicality. This provides runners with an efficient, stable, and comfortable running experience.
