Description

Technical Field

[0001] This invention relates to the field of shoe sole technology, specifically to a shoe sole and a shoe. Background Technology

[0002] Most current shoe soles use foam materials as the midsole. The foam absorbs impact through compression and deformation, and its rebound properties assist foot extension during push-off. It also needs a certain level of support for stability. These performance requirements differ in different areas of the sole; the heel area needs better support and cushioning, while the forefoot area requires better rebound. Current technology generally uses high-performance foam materials for the midsole to ensure good support and cushioning, resulting in poor rebound in the forefoot area. To address this, existing technology incorporates rigid components such as carbon fiber plates into the sole. However, this results in a stiffer overall feel and reduced comfort after the carbon fiber plates are installed. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sole or shoe that can provide better rebound in the forefoot area and improve wearing comfort.

[0004] The applicant found that the problem of a harder feel and poor comfort after installing rigid plates in conventional foam soles is not only due to the high rigidity of the rigid plates themselves, but also because the rigid plates are generally completely surrounded by the midsole material, which makes it difficult for the rigid plates to deform locally due to the lack of deformation space around them.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: In at least one embodiment, a shoe sole is disclosed, the shoe sole comprising: a midsole having an upper support portion and a lower support portion disposed opposite to each other along the thickness direction of the shoe sole in at least the forefoot region; the upper support portion extending downward at an incline having a plurality of first convex ribs extending in the width direction of the shoe sole; the lower support portion extending upward at an incline having a plurality of second convex ribs extending in the width direction of the shoe sole; the first convex ribs and the second convex ribs being arranged at a predetermined distance; and an insert plate extending along the length direction of the shoe sole and extending along the width direction of the shoe sole, the upper surface of the insert plate being connected to each of the first convex ribs, and the lower surface of the insert plate being connected to each of the second convex ribs; wherein the bending stiffness of the insert plate is greater than the bending stiffness of the first convex ribs and the second convex ribs.

[0006] In the above design, the first convex ridge extends downwards from the upper support portion, and the second convex ridge extends upwards from the lower support portion. An insert plate connects the first and second convex ridges, creating a composite support structure in the forefoot area of ​​the sole where the upper support portion, first convex ridge, insert plate, second convex ridge, and lower support portion sequentially cooperate in the thickness direction. When the sole is compressed, the first and second convex ridges can undergo controlled tilting deformation during compression. Furthermore, the space between adjacent first and second convex ridges provides deformation allowance for compression, tilting, and straightening of the ridges, allowing the forefoot area to retain localized flexibility under stress.

[0007] Simultaneously, the upper surface of the insert plate connects to each of the first protruding ridges, and the lower surface connects to each of the second protruding ridges, creating a linkage between the multiple first and second protruding ridges through the insert plate. Therefore, when the foot extends and the forefoot area is subjected to force, the local deformation generated by each of the first and second protruding ridges can be transmitted to the insert plate. The insert plate then forms a force connection extending along the length of the sole between the two sets of protruding ridges, thus organizing the independent deformation responses of the multiple protruding ridges into a continuous force conduction and rebound response. Because the bending stiffness of the insert plate is greater than that of the first and second protruding ridges, the insert plate can provide more stable support and rebound when the ridges are deformed under pressure, limiting excessive tilting of the ridges and transmitting the local force in the forefoot area along the length of the sole.

[0008] Furthermore, since the first and second protrusions are arranged at intervals, the insert plate is not continuously covered and completely restricted by the midsole material on its upper and lower sides. Instead, it has suspended or spanned portions corresponding to the deformation space between adjacent protrusions. When the sole is stepped on, the insert plate receives the load transmitted by the protrusions at the connection point and can undergo a certain degree of bending deformation or elastic relocation at the corresponding deformation space, so that the deformation of the insert plate is not completely limited by the surrounding midsole material. In this way, the sole can obtain local cushioning by utilizing the inclined deformation of the first and second protrusions, and can also form support, rebound, and propulsion in the forefoot area through the insert plate. Moreover, the deformable portion of the insert plate corresponding to the deformation space can reduce the harsh feel caused by the direct support of the entire rigid plate, thus balancing forefoot rebound performance and wearing comfort.

[0009] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge and the second ridge have the same inclination direction, and the lower end of the first ridge and the upper end of the second ridge face each other.

[0010] In the above design, the first and second protruding ridges have the same inclined orientation on the upper and lower sides of the insert plate. When the sole is compressed, the upper and lower sets of protruding ridges have similar tilting tendencies. When the insert plate bears the force between the two sets of protruding ridges, it can obtain a smoother shear and bending response, making the force transmission and rebound process of the area where the structure is located more continuous.

[0011] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge and the second ridge have opposite inclination directions, and the lower end of the first ridge and the upper end of the second ridge face each other.

[0012] In the above design, the first and second convex ridges support the insert plate from opposite directions, so that the insert plate is constrained by both the upper and lower sides during compression. This enhances the local structure's ability to support and retain the insert plate, reduces the possibility of the insert plate shifting under eccentric loading or lateral force, and allows the sole to achieve better torsional resistance and support stability in the corresponding area.

[0013] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge and the second ridge have the same inclination direction, and the lower end of the first ridge and the upper end of the second ridge are offset along the length of the sole.

[0014] In the above design, the first and second convex ridges form a staggered support along the length of the sole. When the sole is compressed, the load can be transmitted sequentially through the upper bearing part, the first convex ridge, the embedded plate, the second convex ridge, and the lower bearing part. The force path is relatively extended, and the local deformation stroke increases accordingly, making the transition of foot pressure in the front-to-back direction smoother.

[0015] In the sole disclosed in at least one embodiment, preferably, the protrusion dimensions of the first ridge and the second ridge in the sole thickness direction gradually increase from front to back.

[0016] In the above design, the protrusion of the ridge in the thickness direction of the sole gradually increases from front to back, so that the rear area of ​​the sole has more support height and cushioning capacity, while the front area of ​​the sole retains more flexible space for push-off deformation.

[0017] In the sole disclosed in at least one embodiment, preferably, the dimensions of the first ridge and the second ridge in the length direction of the sole gradually decrease from front to back.

[0018] In the above design, when the size of the ridge gradually decreases from front to back along the length of the sole, it can further match the force changes at different positions of the sole, so that the rear area forms higher support within a more compact structure, while the front area obtains more space for bending and rebound.

[0019] In the sole disclosed in at least one embodiment, preferably, the insert plate extends through the area where the first and second convex ridges are located along the width direction of the sole; or, the insert plate is located in the middle of the area where the first and second convex ridges are located in the width direction of the sole; or, the insert plate is located on one side of the area where the first and second convex ridges are located in the width direction of the sole.

[0020] In the above design, the connection range and constraint degree of the embedded plate to the first and second convex ridges can be adjusted by the placement of the embedded plate along the width of the sole. When the embedded plate extends through the area containing the first and second convex ridges along the width of the sole, it can form a more complete connection in the width direction, allowing multiple convex ridges to form a more consistent linkage response during compression and rebound, which is suitable for improving the overall support, rebound, and propulsion performance of the corresponding area. When the embedded plate is located in the middle of the area containing the first and second convex ridges along the width of the sole, it can mainly guide and constrain the force-bearing area in the middle of the sole, while allowing the inner and outer areas to retain a certain deformation margin, which is suitable for achieving a balance between support stability and foot feel. When the embedded plate is located on one side of the area containing the first and second convex ridges along the width of the sole, it can form local support for the areas where the force is concentrated on the inner or outer side of the sole, allowing the sole to adjust according to the difference in force on the inner and outer sides and improve support stability under eccentric loading.

[0021] In the sole disclosed in at least one embodiment, preferably, the insert plate is a straight plate.

[0022] In the above design, the straight-plate embedded plate forms a relatively direct force guiding path along the length of the sole, which can stably connect the central areas of multiple first and second convex ridges. When the sole is compressed, the local tilting deformation generated by each convex ridge can be directly transmitted to the embedded plate, and diffused along the length of the sole through the embedded plate, so that the corresponding area obtains more stable support and rebound response.

[0023] In the sole disclosed in at least one embodiment, preferably, the insert plate is a wave plate that undulates in an arc shape along the length of the sole.

[0024] In the above design, the wave plate has an undulating shape along the length of the sole. When under pressure, the embedded plate can bend and release deformation segment by segment along the undulating path, making the load transfer process smoother. Compared with a straight transmission path, the wave plate can provide a longer deformation path and a larger structural adjustment margin. This allows the embedded plate to connect the upper and lower ridges and provide force guidance while retaining more cushioning and clearance space, thereby reducing the harsh feel of rigid plates and improving the cushioning comfort of the corresponding areas.

[0025] In the sole disclosed in at least one embodiment, preferably, the insert plate includes a first plate and a second plate extending along the length direction of the sole. The first plate is curved in an upwardly convex arc shape, and the second plate is curved in a downwardly convex arc shape. The first plate and the second plate have two intersecting positions in the front-rear direction of the sole. The portion enclosed by the first plate and the second plate is provided with a first support block extending along the width direction of the sole, corresponding to the first convex ridge and / or the second convex ridge. The upper end of the first support block is connected to the lower surface of the first plate, and the lower end is connected to the upper surface of the second plate.

[0026] In the above design, the first and second plates intersect at two points in the front-to-back direction, forming an enclosed area between the two intersections. This enclosed area allows the embedded plate to form a composite force-guiding path of local branching, converging, and re-supporting, which is beneficial for distributing the load transmitted from the protrusions to different plate segments. The first support block connects the first and second plates, maintaining the spacing between the two plates within the enclosed area and providing thickness-direction support to the enclosed area, reducing excessive collapse or deformation imbalance in this area under pressure. Thus, this structure can improve local support capacity and structural stability while maintaining the continuity of force guidance in the embedded plate, making it suitable for use in areas of the shoe sole that require strong rebound and stable support.

[0027] In the sole disclosed in at least one embodiment, preferably, the insert plate includes a third plate and a fourth plate extending along the length direction of the sole, the front end of the fourth plate being connected to the rear part of the third plate and cooperating with the third plate in a rearwardly open forked shape; a second support block extending along the width direction of the sole is provided between the third plate and the fourth plate; the upper end of the second support block is connected to the lower surface of the third plate, and the lower end is connected to the upper surface of the fourth plate.

[0028] In the above design, the third and fourth plates form a rearward-opening, forked force-guiding structure, allowing loads from the front or middle to be transferred to different positions via the forked structure. The second support block, positioned between the third and fourth plates, connects the two plates in the thickness direction, limiting excessive opening of the forked area under pressure and enhancing the support stability at the fork. Thus, this structure maintains necessary structural stability while distributing force, making it suitable for sole areas requiring both propulsion efficiency and lateral support.

[0029] In the sole disclosed in at least one embodiment, preferably, the first ridge and the second ridge are integrally formed with the midsole and are made of the same material.

[0030] In the above design, the first and second convex ridges are integrally formed with the midsole, which simplifies the manufacturing process and ensures good structural continuity between the convex ridges and the midsole.

[0031] In the sole disclosed in at least one embodiment, preferably, the midsole includes a midsole body and a support member; the support member includes an upper support portion, a lower support portion, a first convex ridge, and a second convex ridge, the support member is integrally formed and made of a material with an elastic modulus higher than that of the midsole body, and is fixed to the middle part of the midsole body in the thickness direction.

[0032] In the above design, the load-bearing component can provide better support and pressure distribution by relying on its higher elastic modulus, while the midsole body provides cushioning and wrapping on the outside of the load-bearing component, so that the sole achieves a good balance between support stability and wearing comfort.

[0033] In the sole disclosed in at least one embodiment, preferably, the midsole is a foamed midsole, and the insert plate is at least partially made of nylon, thermoplastic polyurethane, and / or carbon fiber. When the midsole includes a load-bearing member, the load-bearing member is made of nylon or thermoplastic polyurethane, and the flexural stiffness of its material is lower than that of the material of the insert plate.

[0034] In the above design, the foamed midsole provides basic cushioning and lightweight performance, while the insert plate, made of nylon, thermoplastic polyurethane, or carbon fiber, can provide different degrees of flexural support as needed. When the flexural stiffness of the load-bearing component is lower than that of the insert plate, the load-bearing component can produce controlled deformation in conjunction with the first and second convex ridges, while the insert plate provides more stable force guidance and constraint, making the structural deformation and force transmission of the sole more layered.

[0035] In a preferred embodiment, a shoe is also disclosed, the shoe including an upper and a sole as described in any of the above embodiments, the upper being attached to the sole.

[0036] In the above design, after the upper and sole are connected, the sole can improve the rebound performance of the forefoot area when running or walking through the cooperation between the midsole, the first ridge, the second ridge and the insert plate, while maintaining good support stability and wearing comfort of the whole shoe.

[0045] This invention provides a shoe that includes a sole and an upper, with the upper attached to the sole.

[0046] The shoe upper can be a structure suitable for connecting to the sole and covering at least a portion of the foot. The upper can be attached to the upper side or periphery of the sole by means of bonding, sewing, heat pressing, or integral molding, so that the upper and sole together define a wearing space for accommodating the foot. The specific structure of the upper can be designed according to the type of shoe, for example, it can be an athletic shoe upper, a casual shoe upper, or other upper structures suitable for use with the sole of this embodiment.

[0047] The main improvement of this invention is in the sole, and the structure of the sole will be described in detail below.

[0048] First, you can refer to Figure 3 , Figure 5 , Figure 7 or Figure 10 These accompanying drawings illustrate a sole component made using the sole structure provided by the present invention. Commonly, the sole includes a midsole 100 and an insert plate 300. The midsole 100 supports the foot and forms the main cushioning and support portion of the sole. The insert plate 300 is disposed within or at least partially disposed within the structural area of ​​the midsole 100 and connected to the ribbed structure in the midsole 100. It is necessary to note that the figures in the accompanying drawings of this invention... Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9 It is mainly used to illustrate the mating relationship between the embedded plate 300 and the first protruding ridge 211 and the second protruding ridge 221; Figure 3 , Figure 5 , Figure 7 and Figure 10 It is mainly used to illustrate the setting of the corresponding structure in the sole of the shoe.

[0049] For ease of explanation, in this embodiment of the invention, the direction of the sole from the toe to the heel or from the heel to the toe is referred to as the sole length direction, the direction between the inner and outer sides of the sole is referred to as the sole width direction, and the direction between the upper and lower sides of the sole is referred to as the sole thickness direction. "Forefoot" refers to the side of the sole closest to the toe, and "rearfoot" refers to the side of the sole closest to the heel. The "forefoot area" refers to the area in the sole corresponding to the forefoot and push-off area of ​​the foot; it may only cover a portion of the front of the sole, or it may extend a distance from the front of the sole towards the midfoot area.

[0050] In this embodiment of the invention, the first protruding ridge 211 and the second protruding ridge 221 are shown in the side view configuration in the accompanying drawings. The first protruding ridge 211 and the second protruding ridge 221 are actually ribs, wall-like parts, or ridge-like parts extending along the width direction of the sole, and are not limited to the planar outline presented by the side view projection in the accompanying drawings. The phrase "the protruding ridge extends along the width direction of the sole" means that the main length direction of the protruding ridge is arranged along the width direction of the sole; the protruding ridge can penetrate the entire width of the corresponding structural area, or it can only extend to a part of the width direction of the structural area. The phrase "arranged at a preset distance" means that there is a gap between two adjacent first protruding ridges 211 and a gap between two adjacent second protruding ridges 221; this gap can form a side-visible hole, groove, opening, or cavity, or it can be expressed as a deformation space between the upper and lower supporting parts 220 that is not continuously filled by the protruding ridges.

[0051] In this embodiment of the invention, the "upper end" of the first protruding ridge 211 refers to the end where the first protruding ridge 211 connects to the upper supporting part 210, and the "lower end" of the first protruding ridge 211 refers to the end where the first protruding ridge 211 is close to and connected to the embedded plate 300. The "lower end" of the second protruding ridge 221 refers to the end where the second protruding ridge 221 connects to the lower supporting part 220, and the "upper end" of the second protruding ridge 221 refers to the end where the second protruding ridge 221 is close to and connected to the embedded plate 300. The lower end of the first protruding ridge 211 and the upper end of the second protruding ridge 221 are "directly opposite" to each other, meaning that their positions in the length direction of the sole are at least partially or substantially corresponding, without requiring that their projected outlines, width ranges, or connection areas be completely identical. The lower end of the first protruding ridge 211 and the upper end of the second protruding ridge 221 are "offset" to each other, meaning that they are offset forward and backward in the length direction of the sole.

[0052] In this embodiment of the invention, the embedded plate 300 extends along the length direction of the sole and extends along the width direction of the sole. For a straight embedded plate 300, it can be a single plate-like piece extending along the length direction of the sole; for an embedded plate 300 in the form of a wave plate, a cross-enclosed plate, or a forked plate, it still has a guiding path extending along the length direction of the sole, and has a certain width or local width distribution in the width direction of the sole. The upper surface of the embedded plate 300 is connected to each of the first protruding ridges 211, and the lower surface is connected to each of the second protruding ridges 221. This means that the embedded plate 300 is located between the upper and lower sets of protruding ridges, and forms a direct or indirect fixed, fitted, bonded, fused, or integrally connected relationship with the first protruding ridges 211 and the second protruding ridges 221, respectively.

[0053] In this embodiment of the invention, the bending stiffness of the embedded plate 300 is greater than that of the first protruding ridge 211 and the second protruding ridge 221. This statement is used to illustrate that the embedded plate 300 has a stronger bending support capacity than the first protruding ridge 211 and the second protruding ridge 221, and does not require the embedded plate 300 to be a completely non-deformable rigid plate. The embedded plate 300 can still undergo elastic bending during stepping, especially in the corresponding interval areas between adjacent first protruding ridges 211 or adjacent second protruding ridges 221, where local bending or elastic yielding can occur. The first protruding ridges 211 and the second protruding ridge 221 are mainly used to form a compressible and tiltable deformable support base on the upper and lower sides of the embedded plate 300.

[0054] The specific structures of each embodiment are described below.

[0055] Example 1 Reference Figure 1 Example 1 discloses a shoe sole with a basic configuration. The midsole 100 has an upper support portion 210 and a lower support portion 220 arranged opposite to each other along the thickness direction of the sole, at least in the forefoot region. The upper support portion 210 is located above the lower support portion 220, and a structural area for arranging a first protruding ridge 211, a second protruding ridge 221, and an insert plate 300 is formed between them. The upper support portion 210 and the lower support portion 220 can be integral plates, or they can be partial sheets, frames, or structures that continuously transition with other parts of the midsole 100.

[0056] The upper support portion 210 extends downward at an incline and is provided with a plurality of first protruding ribs 211. The upper end of each first protruding rib 211 is connected to the upper support portion 210, and the lower end extends toward the location of the embedded plate 300. The lower support portion 220 extends upward at an incline and is provided with a plurality of second protruding ribs 221. The lower end of each second protruding rib 221 is connected to the lower support portion 220, and the upper end extends toward the location of the embedded plate 300. The first protruding ribs 211 and the second protruding ribs 221 are respectively disposed on the upper and lower sides of the embedded plate 300, so that the embedded plate 300 is located between the upper and lower sets of protruding ribs in the thickness direction of the sole.

[0057] exist Figure 1 In the configuration shown, several first ridges 211 are spaced apart along the length of the sole, and several second ridges 221 are also spaced apart along the length of the sole. Both the first ridges 211 and the second ridges 221 extend along the width of the sole. A first space is formed between adjacent first ridges 211, and a second space is formed between adjacent second ridges 221. The first and second spaces can form lateral openings on the side of the sole, or they can form internal deformation spaces between the upper support portion 210 and the lower support portion 220. These spaces allow the ridges to undergo localized tilting deformation under pressure, and also allow the embedded plate 300 to have a certain bending allowance at the cross-position not connected to the ridges.

[0058] An insert plate 300 is disposed between the upper support portion 210 and the lower support portion 220 and extends along the length of the sole. The upper surface of the insert plate 300 is connected to the lower end of a plurality of first protrusions 211, and the lower surface of the insert plate 300 is connected to the upper end of a plurality of second protrusions 221. Figure 1 In this design, the embedded plate 300 is a straight plate, which extends in a relatively straight direction when viewed from the side. The straight plate here does not need to be a perfectly straight plate in the mathematical sense, nor does it exclude the possibility that the embedded plate 300 will be slightly curved due to the overall warping of the sole or the shape of the sole; as long as it mainly forms a relatively direct extension path in the length direction relative to the wave plate, the cross-enclosure plate and the forked plate, it can be understood as a straight plate.

[0059] In Embodiment 1, the first protruding rib 211 and the second protruding rib 221 can be arranged in the same direction of inclination and with their ends facing each other, or in opposite directions of inclination and with their ends facing each other, or in the same direction of inclination but with their ends staggered along the length of the sole. Figure 1 It is mainly used to illustrate the basic connection relationship between the embedded plate 300 and the upper and lower sets of protruding ribs. It should not be interpreted as limiting all first protruding ribs 211 and second protruding ribs 221 to have the same tilt angle, length dimension or corresponding upper and lower positions.

[0060] In other embodiments, different ridge arrangements can be used at different locations on the same sole. For example, the first ridge 211 and the second ridge 221 located at the forefoot can be arranged with the same inclination direction and their ends facing each other to form a more continuous compression and rebound path; the first ridge 211 and the second ridge 221 located at the mid-forefoot or lateral support position can be arranged with opposite inclination directions and their ends facing each other to form relative support; the first ridge 211 and the second ridge 221 located at positions where increased deformation travel is required can be arranged with the same inclination direction but staggered ends. These different arrangements can be used individually or in combination on the same sole.

[0061] In other embodiments, the protrusion dimensions of the first ridge 211 and the second ridge 221 in the sole thickness direction can gradually increase from front to back. For the first ridge 211, the protrusion dimension can be understood as the distance it extends downward from the upper support portion 210; for the second ridge 221, the protrusion dimension can be understood as the distance it extends upward from the lower support portion 220. This gradual increase can be a continuous gradient or a segmented change, and it is not required that each adjacent ridge changes strictly according to the same difference. The dimensions of the first ridge 211 and the second ridge 221 in the sole length direction can also gradually decrease from front to back. The dimension in the sole length direction can be understood as the dimension occupied by the ridge in the front-back direction in a side view or its projected dimension in the sole length direction.

[0062] In other embodiments, the embedding plate 300 can penetrate the area where the first protruding ridge 211 and the second protruding ridge 221 are located along the width direction of the sole, or it can be disposed in the middle of this area along the width direction of the sole, or it can be disposed on one side of this area along the width direction of the sole. "Penetrating" means that the embedding plate 300 extends from one side to the other or substantially extends to the other side in the corresponding structural area along the width direction. "Middle" means that the embedding plate 300 is mainly disposed in the middle area between the inner and outer sides of the sole. "One side" means that the embedding plate 300 is disposed biased towards the inner or outer side of the sole. The above arrangement can be selected according to the stress area of ​​the foot and the lateral support requirements of the sole.

[0063] In other embodiments, the first ridge 211 and the second ridge 221 can be integrally formed with the midsole 100 and made of the same material. In this case, the upper support portion 210, the lower support portion 220, the first ridge 211, and the second ridge 221 can all be formed of the material of the midsole 100, and the insert plate 300 is embedded or sandwiched between the upper and lower ridges as an independent plate-like component. The first ridge 211 and the second ridge 221 can also be part of the support member 200 made of a different material than the midsole body 110, and the support member 200 is then fixed to the midsole body 110, as can be seen in the embodiments described later.

[0064] Example 2 Reference Figure 2 and Figure 3 The main difference between Embodiment 2 and Embodiment 1 lies in the specific configuration of the embedding plate 300. In Embodiment 2, the embedding plate 300 includes a first plate 311 and a second plate 312 extending along the length of the sole. The first plate 311 is curved in an upwardly convex arc shape, and the second plate 312 is curved in a downwardly convex arc shape. Here, "upwardly convex" and "downwardly convex" refer to... Figure 2 The description is based on the thickness direction of the sole in the side view shown. The first plate 311 and the second plate 312 can both be strip plates, sheet plates, or plate-like components with a certain width.

[0065] The first plate 311 and the second plate 312 have two intersecting positions in the front-to-back direction of the sole. These intersecting positions can be where the first plate 311 and the second plate 312 are actually connected, intersecting, or integrally joined, or they can be positions where the first plate 311 and the second plate 312 intersect each other in a side view and are fixedly connected at corresponding positions by a connecting structure. The first plate 311 and the second plate 312 together enclose a central region between the two intersecting positions, giving the embedded plate 300 a similar enclosed or fish-belly-like structure within this region.

[0066] A first support block 411 is provided in the portion enclosed by the first plate 311 and the second plate 312. The first support block 411 extends along the width direction of the sole. The upper end of the first support block 411 is connected to the lower surface of the first plate 311, and the lower end is connected to the upper surface of the second plate 312. The first support block 411 can be a strip-shaped support block that extends continuously along the width direction of the sole, or it can be a support block that is segmented along the width direction of the sole. The first support block 411 can be integrally formed with the first plate 311 and the second plate 312, or it can be connected between the first plate 311 and the second plate 312 by bonding, welding, embedding, or other fixing methods.

[0067] Reference Figure 2 The first protruding ridge 211 and the second protruding ridge 221 can be respectively set in the areas where the first plate 311, the second plate 312, and the first support block 411 are located. The lower end of the first protruding ridge 211 can be connected to the upper surface of the first plate 311, the upper surface of the second plate 312, or the intersection area of ​​the first plate 311 and the second plate 312; the upper end of the second protruding ridge 221 can be connected to the lower surface of the first plate 311, the lower surface of the second plate 312, or the intersection area of ​​the first plate 311 and the second plate 312. Figure 2 This diagram illustrates only one possible connection position. In actual implementation, the connection position of the protruding ribs can be adjusted according to the bending paths of the first plate 311 and the second plate 312.

[0068] Reference Figure 3In the sole of Embodiment 2, the aforementioned insert plate 300 is disposed in the forefoot area of ​​the midsole 100. The midsole 100 forms the outer contour of the sole, and the first convex rib 211 extends downward from the upper support portion 210 and connects to the insert plate 300, and the second convex rib 221 extends upward from the lower support portion 220 and connects to the insert plate 300. Figure 3 Only a partial structure visible on the side of the sole is shown; the complete extension in the width direction of the sole is not shown. The first plate 311, the second plate 312, the first support block 411, the first ridge 211, and the second ridge 221 can all extend in the width direction of the sole. Structures not specifically described in Embodiment 2 can be understood with reference to Embodiment 1.

[0069] Example 3 Reference Figure 4 and Figure 5 The main difference between Example 3 and Example 1 is that the embedded plate 300 is a wave plate that undulates in an arc shape along the length of the sole. In a side view, the wave plate forms an undulating extension path along the length of the sole. This undulating path can be a continuous arc, or it can be formed by multiple arc segments, transition segments, or approximately arc segments connected sequentially. The amplitude, number of undulations, and specific bending positions of the wave plate can be set according to the space of the forefoot area, midfoot area, or other corresponding areas of the sole.

[0070] Reference Figure 4 An embedded plate 300 in the form of a wave plate is located between the upper support portion 210 and the lower support portion 220, and extends between the first protruding ridge 211 and the second protruding ridge 221. Because the wave plate itself has an undulating shape, its connection position with different first protruding ridges 211 and second protruding ridges 221 can be at different heights, or at different front-to-back positions along the length of the sole. The first protruding ridge 211 can be connected to the upper surface of the wave plate or the area near the crest, and the second protruding ridge 221 can be connected to the lower surface of the wave plate or the area near the trough; however, this correspondence is not fixed, as long as the wave plate can connect the upper and lower protruding ridges and form a continuous plate-like structure along the length of the sole.

[0071] Reference Figure 5 In embodiment 3, the midsole 100 may include a midsole body 110 and a support member 200. The support member 200 is disposed in the middle of the midsole body 110 in the thickness direction and may be located at least in the forefoot area of ​​the sole. The support member 200 includes an upper support portion 210, a lower support portion 220, a first protruding ridge 211, and a second protruding ridge 221. An insert plate 300 is disposed within the support member 200 and is connected to the first protruding ridge 211 and the second protruding ridge 221 in the support member 200. The midsole body 110 may cover the upper side, lower side, or peripheral side of the support member 200, or at least a portion of the support member 200 may be exposed on the side of the sole. Figure 5The support member 200 shown is located on the side of the forefoot area of ​​the sole. In actual implementation, the support member 200 can also extend to the midfoot area.

[0072] Example 4 Reference Figure 6 and Figure 7 The main difference between Example 4 and Example 1 is that the sole uses a bearing member 200 as an independent structural member for setting the first protruding ridge 211, the second protruding ridge 221 and the embedded plate 300, and the embedded plate 300 forms a long linear force guiding configuration within the bearing member 200.

[0073] Reference Figure 6 The insert plate 300 is a straight plate located between the first protruding ridge 211 and the second protruding ridge 221. The first protruding ridge 211 extends downward from the upper supporting part 210 to the insert plate 300, and the second protruding ridge 221 extends upward from the lower supporting part 220 to the insert plate 300. Multiple first protruding ridges 211 and multiple second protruding ridges 221 are arranged at intervals along the length of the sole and are respectively connected to the insert plate 300. Figure 6 The configuration shown can be used as the internal configuration of the support member 200, or as a partial configuration when the midsole 100 is integrally molded.

[0074] Reference Figure 7 The support member 200 is fixed to the middle of the midsole body 110 in the thickness direction and extends along the length of the sole. The support member 200 can extend from the forefoot area to the midfoot area or heel, and its outer contour can be adapted to the side contour of the midsole body 110. The support member 200 can be entirely embedded in the midsole body 110, or it can be partially exposed on the side of the midsole body 110. The upper support portion 210, the lower support portion 220, the first protruding ridge 211, and the second protruding ridge 221 can all be part of the support member 200 and integrally formed with the support member 200. The insert plate 300 can be pre-embedded when the support member 200 is formed, or it can be inserted into the corresponding slot, hole, or connection position after the support member 200 is formed.

[0075] In this embodiment, the support member 200 can be made of a material with a higher elastic modulus than the midsole body 110. The midsole body 110 can be a foamed material used to form the outer cushioning body of the shoe sole; the support member 200 can be made of nylon, thermoplastic polyurethane, or other supportive elastic materials; the embedded plate 300 can be made of a material or structure with a higher bending stiffness than the support member 200. It should be noted that the higher material stiffness of the support member 200 than the midsole body 110 does not mean that the support member 200 is an indeformable rigid component; the support member 200 can still undergo elastic deformation during footsteps.

[0076] Example 5 Reference Figure 8The main difference between Embodiment 5 and Embodiment 1 is that the embedded plate 300 includes a third plate 313 and a fourth plate 314 extending along the length of the sole. The front end of the fourth plate 314 connects to the rear of the third plate 313 and cooperates with the third plate 313 in a rearwardly open forked shape. The term "rearwardly open" means that when the third plate 313 and the fourth plate 314 extend rearward from the connection position at the front or middle, the distance between them gradually increases along the length of the sole, or at least forms an opening at the rear. The third plate 313 and the fourth plate 314 can both be strip plates or sheet plates, and they can be formed integrally or formed into a forked structure by connection, overlap, or fixation.

[0077] A second support block 412 is provided between the third plate 313 and the fourth plate 314. The second support block 412 extends along the width direction of the sole. The upper end of the second support block 412 is connected to the lower surface of the third plate 313, and the lower end is connected to the upper surface of the fourth plate 314. The second support block 412 can be located in the bifurcation area between the third plate 313 and the fourth plate 314 to maintain the relative distance between the third plate 313 and the fourth plate 314 in the thickness direction of the sole. There can be one or more second support blocks 412; when multiple second support blocks 412 are provided, they can be arranged at intervals along the length direction or the width direction of the sole.

[0078] In Embodiment 5, the first protruding ridge 211 and the second protruding ridge 221 can be connected to the third plate 313 and / or the fourth plate 314, respectively. Specifically, a portion of the first protruding ridge 211 can be connected to the upper surface of the third plate 313 or the upper surface of the fourth plate 314, and a portion of the second protruding ridge 221 can be connected to the lower surface of the third plate 313 or the lower surface of the fourth plate 314. The bifurcation area between the third plate 313 and the fourth plate 314 can correspond to one or more of the first protruding ridges 211 and the second protruding ridges 221. The connection relationships of the upper bearing portion 210, the lower bearing portion 220, the first protruding ridge 211, and the second protruding ridge 221, which are not specifically described in Embodiment 5, can be understood with reference to Embodiment 1.

[0079] Example 6 Reference Figure 9 and Figure 10 The main difference between Embodiment 6 and Embodiment 1 lies in the vertical correspondence between the first protruding ridge 211 and the second protruding ridge 221, and the arrangement range of the embedded plate 300. (Refer to...) Figure 9The embedded plate 300 can be a straight plate and is disposed between the upper support portion 210 and the lower support portion 220. The first protruding ridge 211 and the second protruding ridge 221 are located on the upper and lower sides of the embedded plate 300, respectively. Compared with Embodiment 1, in Embodiment 6, at least some of the first protruding ridges 211 and the second protruding ridge 221 can form different inclined mating arrangements on the upper and lower sides of the embedded plate 300. For example, the first protruding ridge 211 and the second protruding ridge 221 can be arranged with opposite inclination directions and their ends facing each other, or they can be arranged with the same inclination direction but their ends are staggered along the length of the sole. Figure 9 The diagram is only intended to illustrate one type of convex edge fit relationship, and it is possible that different convex edge fit methods are used in different positions on the same sole.

[0080] Reference Figure 10 In the sole of Embodiment 6, the insert plate 300 extends rearward from the forefoot region along the length of the sole and connects with multiple first protruding ribs 211 and second protruding ribs 221. In this embodiment, the upper support portion 210 and the lower support portion 220 can extend a considerable distance along the length of the sole, and the first protruding ribs 211 and second protruding ribs 221 can be arranged at intervals within this length range. The insert plate 300 can be mainly located in the forefoot region or can extend to the midfoot region to adapt to the force path of the foot during the transition from forefoot push-off to midfoot.

[0081] In Embodiment 6, the protrusion dimensions of the first protruding ridge 211 and the second protruding ridge 221 in the thickness direction of the sole can gradually increase from front to back, and / or, the dimensions of the first protruding ridge 211 and the second protruding ridge 221 in the length direction of the sole can gradually decrease from front to back. The aforementioned dimensional changes can be provided on one of the first protruding ridge 211 and the second protruding ridge 221, or simultaneously on both. The gradual change from front to back can be a continuous gradient or a segmented change. Figure 10 The sole structure shown is only an illustration of its overall layout. In actual implementation, the number of protrusions, the spacing between protrusions, the protrusion extension size, the length direction dimension of the protrusions, and the extension length of the embedded plate 300 can be adjusted according to the sole size, wearing scenario, and midsole 100 material.

[0082] This invention also discloses a shoe. The shoe includes an upper and a sole as described in any of the above embodiments. The upper is attached to the sole. The upper can be attached to the sole by adhesive bonding, sewing, hot pressing, lasting, or other footwear manufacturing methods. The upper can be a knitted upper, mesh upper, leather upper, synthetic leather upper, composite material upper, or other upper structures suitable for attachment to the aforementioned sole.

[0083] It should be noted that Embodiments 1 to 6 are for illustrating different specific structures of the midsole 100, the support member 200, the first protruding ridge 211, the second protruding ridge 221, and the insert plate 300 in this invention, and do not imply that the embodiments are mutually exclusive. Technical features in each embodiment can be combined without structural contradictions. For example, the configuration of the first plate 311, the second plate 312, and the first support block 411 in Embodiment 2 can be used in conjunction with the support member 200 in Embodiment 4; the wave plate in Embodiment 3 can be disposed within the integrally formed midsole 100 or within the support member 200; the forked insert plate 300 in Embodiment 5 can be disposed in the forefoot area, or in the mid-forefoot or a partial lateral support area; the gradual change in the size of the protruding ridge in Embodiment 6 can also be applied to any of the insert plate 300 configurations in Embodiments 1 to 5.

[0084] In addition, refer to Figures 11 to 16 The figures illustrate the deformation and recovery deformation processes under compression in Examples 1 to 6, respectively, for specimens of the same size. In conjunction with these figures, a further understanding of the structure of the shoe soles involved in Examples 1 to 6 can be achieved.

[0085] In at least one embodiment, a shoe sole is disclosed, comprising: a midsole 100, which has an upper support portion 210 and a lower support portion 220 disposed opposite to each other along the thickness direction of the shoe sole in at least the forefoot region; the upper support portion 210 extends downward at an incline and is provided with a plurality of first protruding ribs 211 extending in the width direction of the shoe sole; the lower support portion 220 extends upward at an incline and is provided with a plurality of second protruding ribs 221 extending in the width direction of the shoe sole; the first protruding ribs 211 and the second protruding ribs 221 are respectively arranged at a predetermined distance; and an insert plate 300, which extends along the length direction of the shoe sole and along the width direction of the shoe sole, and its upper surface is connected to each of the first protruding ribs 211, and its lower surface is connected to each of the second protruding ribs 221; wherein the bending stiffness of the insert plate 300 is greater than the bending stiffness of the first protruding ribs 211 and the second protruding ribs 221.

[0086] In the above design, the first ridge 211 extends downward from the upper support portion 210, and the second ridge 221 extends upward from the lower support portion 220. The insert plate 300 connects the first ridge 211 and the second ridge 221, forming a composite support structure in the forefoot area of ​​the sole in the thickness direction, consisting of the upper support portion 210, the first ridge 211, the insert plate 300, the second ridge 221, and the lower support portion 220 in sequence. When the sole is compressed, the first ridge 211 and the second ridge 221 can generate controlled tilting deformation during compression, and the space between adjacent first ridges 211 and adjacent second ridges 221 provides deformation margin for the compression, tilting, and straightening of the ridges, allowing the forefoot area to retain local flexibility under force.

[0087] Simultaneously, the upper surface of the insert plate 300 is connected to each of the first protruding ribs 211, and the lower surface is connected to each of the second protruding ribs 221, so that the multiple first protruding ribs 211 and second protruding ribs 221 form a linkage relationship through the insert plate 300. Therefore, when the foot extends and the forefoot area is subjected to force, the local deformation generated by each of the first protruding ribs 211 and second protruding ribs 221 can be transmitted to the insert plate 300, and the insert plate 300 forms a force connection extending along the length of the sole between the two sets of protruding ribs, thereby organizing the independent deformation response of multiple protruding ribs into a continuous force guiding and rebound response. Because the bending stiffness of the insert plate 300 is greater than that of the first protruding ribs 211 and second protruding ribs 221, the insert plate 300 can provide more stable support and rebound when the protruding ribs are deformed under pressure, limiting excessive tilting of the protruding ribs and transmitting the local force in the forefoot area to the length of the sole.

[0088] Furthermore, since the first protrusions 211 and the second protrusions 221 are arranged at intervals, the insert plate 300 is not continuously covered and completely restricted by the midsole 100 material on its upper and lower sides. Instead, it has a suspended or spanned portion corresponding to the deformation space between adjacent protrusions. When the sole is stepped on, the insert plate 300 receives the load transmitted by the protrusions at the position where it connects with them, and can undergo a certain degree of bending deformation or elastic relief at the position corresponding to the deformation space, so that the deformation of the insert plate 300 is not completely limited by the surrounding midsole 100 material. In this way, the sole can obtain local cushioning by utilizing the inclined deformation of the first protrusions 211 and the second protrusions 221, and can also form support, rebound, and propulsion in the forefoot area through the insert plate 300. Moreover, the deformable portion of the insert plate 300 corresponding to the deformation space can weaken the harsh feel brought about by the direct support of the entire rigid plate, thereby balancing forefoot rebound performance and wearing comfort.

[0089] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge 211 and the second ridge 221 have the same inclination direction, and the lower end of the first ridge 211 and the upper end of the second ridge 221 face each other.

[0090] In the above design, the first protruding rib 211 and the second protruding rib 221 have the same inclined orientation on the upper and lower sides of the embedded plate 300. When the sole is compressed, the upper and lower sets of protruding ribs have similar tilting tendencies. When the embedded plate 300 bears the force between the two sets of protruding ribs, it can obtain a smoother shear and bending response, making the force transmission and rebound process of the area where the structure is provided more continuous.

[0091] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge 211 and the second ridge 221 are inclined in opposite directions, and the lower end of the first ridge 211 and the upper end of the second ridge 221 face each other.

[0092] In the above design, the first protruding rib 211 and the second protruding rib 221 support the embedded plate 300 from opposite directions, so that the embedded plate 300 is constrained by both the upper and lower sides during compression. This can enhance the local structure's ability to support and retain the embedded plate 300, reduce the possibility of the embedded plate 300 shifting under eccentric load or lateral force, and enable the sole to obtain better torsional resistance and support stability in the corresponding area.

[0093] In the sole disclosed in at least one embodiment, preferably, at least a portion of the first ridge 211 and the second ridge 221 have the same inclination direction, and the lower end of the first ridge 211 and the upper end of the second ridge 221 are offset along the length direction of the sole.

[0094] In the above design, the first convex rib 211 and the second convex rib 221 form a staggered support in the length direction of the sole. After the sole is compressed, the load can be transmitted sequentially through the upper bearing part 210, the first convex rib 211, the embedded plate 300, the second convex rib 221 and the lower bearing part 220. The force path is relatively extended, and the local deformation stroke increases accordingly, making the transition of foot pressure in the front-back direction smoother.

[0095] In the sole disclosed in at least one embodiment, preferably, the protrusion dimensions of the first ridge 211 and the second ridge 221 in the sole thickness direction gradually increase from front to back.

[0096] In the above design, the protrusion of the ridge in the thickness direction of the sole gradually increases from front to back, so that the rear area of ​​the sole has more support height and cushioning capacity, while the front area of ​​the sole retains more flexible space for push-off deformation.

[0097] In the sole disclosed in at least one embodiment, preferably, the dimensions of the first ridge 211 and the second ridge 221 in the length direction of the sole gradually decrease from front to back.

[0098] In the above design, when the size of the ridge gradually decreases from front to back along the length of the sole, it can further match the force changes at different positions of the sole, so that the rear area forms higher support within a more compact structure, while the front area obtains more space for bending and rebound.

[0099] In the sole disclosed in at least one embodiment, preferably, the insert plate 300 extends through the area where the first ridge 211 and the second ridge 221 are located along the width direction of the sole; or, the insert plate 300 is located in the middle of the area where the first ridge 211 and the second ridge 221 are located in the width direction of the sole; or, the insert plate 300 is located on one side of the area where the first ridge 211 and the second ridge 221 are located in the width direction of the sole.

[0100] In the above design, the connection range and constraint degree of the embedded plate 300 to the first protruding ridge 211 and the second protruding ridge 221 can be adjusted by the arrangement of the embedded plate 300 in the width direction of the sole. When the embedded plate 300 extends through the area where the first protruding ridge 211 and the second protruding ridge 221 are located along the width direction of the sole, the embedded plate 300 can form a relatively complete connection in the width direction, so that multiple protruding ridges can form a more consistent linkage response during compression and rebound, which is suitable for improving the overall support, rebound and propulsion performance of the corresponding area. When the embedded plate 300 is located in the middle of the area where the first protruding ridge 211 and the second protruding ridge 221 are located in the width direction of the sole, the embedded plate 300 can mainly guide and constrain the force-bearing area in the middle of the sole, while allowing the inner and outer areas to retain a certain deformation margin, which is suitable for achieving a balance between support stability and foot feel. When the embedded plate 300 is located on one side of the area where the first protruding ridge 211 and the second protruding ridge 221 are located in the width direction of the sole, it can form local support for the area where the force is concentrated on the inner or outer side of the sole, so that the sole can be adjusted according to the difference in force on the inner and outer sides and improve the support stability under the condition of unbalanced load.

[0101] In the sole disclosed in at least one embodiment, preferably, the insert plate 300 is a straight plate.

[0102] In the above design, the straight-plate embedded plate 300 forms a relatively direct force guiding path along the length of the sole, which can stably connect the central areas of multiple first ridges 211 and second ridges 221. When the sole is compressed, the local tilting deformation generated by each ridge can be directly transmitted to the embedded plate 300, and diffused along the length of the sole through the embedded plate 300, so that the corresponding area obtains more stable support and rebound response.

[0103] In the sole disclosed in at least one embodiment, preferably, the embedded plate 300 is a wave plate that undulates in an arc shape along the length direction of the sole.

[0104] In the above design, the wave plate has an undulating shape along the length of the sole. When under pressure, the embedded plate 300 can bend and release deformation segment by segment along the undulating path, making the load transfer process smoother. Compared with a straight transmission path, the wave plate can provide a longer deformation path and a larger structural adjustment margin. This allows the embedded plate 300 to retain more cushioning and clearance space while connecting the upper and lower convex ridges and providing force guidance. This reduces the harsh feel of rigid plates and improves the cushioning comfort of the corresponding areas.

[0105] In the sole disclosed in at least one embodiment, preferably, the embedded plate 300 includes a first plate 311 and a second plate 312 extending along the length direction of the sole. The first plate 311 is curved in an upwardly convex arc shape, and the second plate 312 is curved in a downwardly convex arc shape. The first plate 311 and the second plate 312 have two intersecting positions in the front-rear direction of the sole. The portion enclosed by the first plate 311 and the second plate 312 is provided with a first support block 411 extending along the width direction of the sole, corresponding to the first protruding ridge 211 and / or the second protruding ridge 221. The upper end of the first support block 411 is connected to the lower surface of the first plate 311, and the lower end is connected to the upper surface of the second plate 312.

[0106] In the above design, the first plate 311 and the second plate 312 intersect at two points in the front-rear direction, forming an enclosed area between the two intersections. This enclosed area allows the embedded plate 300 to form a composite force guiding path that locally branches, converges, and re-supports the load, which is beneficial for distributing the load transmitted from the protrusion to different plate segments. The first support block 411 connects the first plate 311 and the second plate 312, maintaining the spacing between the two plates within the enclosed area and providing thickness-direction support to the enclosed area, reducing excessive collapse or deformation imbalance in this area under pressure. Thus, this structure can improve local support capacity and structural stability while maintaining the continuity of force guiding of the embedded plate 300, making it suitable for use in areas of the shoe sole that require strong rebound and stable support.

[0107] In the sole disclosed in at least one embodiment, preferably, the embedded plate 300 includes a third plate 313 and a fourth plate 314 extending along the length direction of the sole, the front end of the fourth plate 314 is connected to the rear part of the third plate 313 and cooperates with the third plate 313 in a rearwardly open forked shape; a second support block 412 extending along the width direction of the sole is provided between the third plate 313 and the fourth plate 314; the upper end of the second support block 412 is connected to the lower surface of the third plate 313, and the lower end is connected to the upper surface of the fourth plate 314.

[0108] In the above design, the third plate 313 and the fourth plate 314 form a rearward-opening, forked force-guiding structure, allowing loads from the front or middle to be transferred to different positions via the forked structure. The second support block 412, positioned between the third plate 313 and the fourth plate 314, connects the two plates in the thickness direction, limiting excessive opening of the forked area under pressure and enhancing the support stability at the fork. Thus, this structure maintains necessary structural stability while forming a force-guiding distribution, making it suitable for sole areas requiring both propulsion efficiency and lateral support.

[0109] In the sole disclosed in at least one embodiment, preferably, the first ridge 211 and the second ridge 221 are integrally formed with the midsole 100 and are made of the same material.

[0110] In the above design, the first protruding rib 211 and the second protruding rib 221 are integrally formed with the midsole 100, which can simplify the manufacturing process and make the protruding rib and the midsole 100 have good structural continuity.

[0111] In the sole disclosed in at least one embodiment, preferably, the midsole 100 includes a midsole body 110 and a support member 200; the support member 200 includes an upper support portion 210, a lower support portion 220, a first convex ridge 211, and a second convex ridge 221, the support member 200 is integrally formed and made of a material with an elastic modulus higher than that of the midsole body 110, and is fixed to the middle part of the midsole body 110 in the thickness direction.

[0112] In the above design, the support component 200 can provide better support and pressure distribution by relying on its higher elastic modulus, while the midsole body 110 provides cushioning and wrapping on the outside of the support component 200, so that the sole can achieve a good balance between support stability and wearing comfort.

[0113] In the sole disclosed in at least one embodiment, preferably, the midsole 100 is a foamed midsole 100, and the insert plate 300 is at least partially made of nylon, thermoplastic polyurethane, and / or carbon fiber material. When the midsole 100 includes a support member 200, the support member 200 is made of nylon or thermoplastic polyurethane material, and the flexural stiffness of its material is lower than the flexural stiffness of the material of the insert plate 300.

[0114] In the above design, the foamed midsole 100 provides basic cushioning and lightweight performance, while the insert plate 300, made of nylon, thermoplastic polyurethane, or carbon fiber, can provide different degrees of flexural support as needed. When the flexural stiffness of the load-bearing member 200 is lower than that of the insert plate 300, the load-bearing member 200 can cooperate with the first protrusion 211 and the second protrusion 221 to produce controlled deformation, and the insert plate 300 provides more stable force guidance and constraint between them, making the structural deformation and force transmission of the sole more layered.

[0115] In a preferred embodiment, a shoe is also disclosed, the shoe including an upper and a sole as described in any of the above embodiments, the upper being attached to the sole.

[0116] In the above design, after the upper and sole are connected, the sole can improve the rebound performance of the forefoot area when running or walking through the cooperation between the midsole 100, the first convex ridge 211, the second convex ridge 221 and the insert plate 300, and maintain good support stability and wearing comfort of the whole shoe.

[0117] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention 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 invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
