Description

Technical Field

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

[0002] With socio-economic development and the continuous improvement of people's living standards, more and more people are paying attention to health and participating more in sports and fitness in their daily lives. During activities such as running, due to inertia, the sole of the shoe experiences downward pressure from the body's weight and a counter-impact force from the ground (generally equivalent to 3 to 5 times the body weight) at the moment of impact. This impact can easily cause damage to the knee and / or ankle joints. Therefore, shoes are footwear designed to protect the legs and feet from injury, and the cushioning function of shoes is extremely important and necessary.

[0003] Many shoes on the market with cushioning features improve the material or structure of the sole. For example, in terms of sole material, they use foamed thermoplastic polyurethane material with good cushioning effect, and in terms of sole structure, they design air cushions, shock-absorbing columns, and other structures. However, regarding improvements to sole materials, different parts of the sole require different cushioning performance, and soles made of the same material cannot meet these needs. As for improvements to sole structure, there are problems such as an overall stiff structure and low comfort. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a shock-absorbing and supportive sole and shoe, which has the advantages of good shock-absorbing and supportive performance and high wearing comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Technical Solution 1: A cushioning and support sole, comprising a midsole, wherein the midsole is provided with a plurality of transverse through holes spaced apart from front to back along the width direction, and the portion between adjacent transverse through holes forms a transverse column extending along the width direction; the end face of the transverse column in the width direction includes a top wall, a bottom wall, a first side wall, a second side wall, and a connecting wall; the top wall and the bottom wall are arranged along the thickness direction, the first side wall and the second side wall are arranged along the length direction, and their ends in the thickness direction are respectively connected to the top wall and the bottom wall; the connecting wall connects the first side wall and the second side wall along the length direction; the first side wall and the second side wall are each divided by the connecting wall along the thickness direction by a first support segment and a second support segment. Two support sections; the two first support sections, the top wall, and the connecting wall together form a first groove recessed along the width direction, and the two second support sections, the bottom wall, and the connecting wall together form a second groove recessed along the width direction; the first groove and the second groove are arranged along the thickness direction; the distance between the first side wall and the second side wall on the projection plane perpendicular to the width direction first increases and then decreases from top to bottom, and the position where the distance decreases from large to small is consistent with the position of the connecting wall; the size of the transverse through hole on the projection plane perpendicular to the width direction along the length direction first decreases and then increases from top to bottom, and the position where the size increases from small to large is consistent with the position of the connecting wall in the adjacent transverse column.

[0006] Technical Solution 2 based on Technical Solution 1: The top and bottom walls of the transverse through hole in the thickness direction extend in the same direction as the upper and lower surfaces of the middle bottom at the same location.

[0007] Technical Solution 3 based on Technical Solution 1: The bottom of the midsole is recessed at the middle position in the width direction and has a bottom groove closed at both ends along the length direction; the length range of the bottom groove corresponds to at least all the transverse columns; the transverse through hole forms an opening on the side groove wall of the bottom groove with the same shape as the transverse through hole on the projection plane perpendicular to the width direction.

[0008] Technical Solution 4 based on Technical Solution 1: The dimension of the first support segment in the thickness direction is smaller than the dimension of the second support segment in the thickness direction.

[0009] Technical Solution 5 based on Technical Solution 4: The circumferential dimensions of the first groove and the second groove gradually increase from the bottom to the top of the groove.

[0010] Technical Solution Six based on Technical Solution Five: The bottom surface of the second groove is in a stepped shape that descends gradually from the connecting wall.

[0011] Technical solution seven based on technical solution three: also includes a reinforcing plate, which extends along the length and width directions and penetrates each of the transverse columns; the reinforcing plate forms the bottom of the groove of the bottom opening.

[0012] Technical solution eight, based on technical solution seven: the position of the reinforcing plate in each of the transverse columns corresponds to the position of the connecting wall of that transverse column.

[0013] Technical solution nine based on technical solution seven: The reinforcing plate has a preset distance between its two sides in the width direction and the two sides of the midsole in the width direction.

[0014] In addition, the present invention also provides technical solution ten: a shoe, which includes an upper and further includes a cushioning support sole based on any one of technical solutions one to nine, wherein the upper is attached to the sole.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: Technical Solution 1 provides a cushioning and support sole. The midsole of this sole features transverse channels, with transverse columns forming between these channels. By extending the midsole through its width, the weight of the midsole is reduced, while simultaneously providing multiple easily bendable sections along its length, thus improving wearing comfort. The transverse columns play a crucial role in cushioning and support. Because the transverse channels significantly reduce the overall structural strength of the midsole, the cushioning and support performance is concentrated at the transverse columns. Therefore, the transverse columns need to provide more efficient cushioning and support compared to conventional midsole structures. In this solution, a top wall, a bottom wall, two side walls, and a connecting wall are provided at the end faces of the transverse columns. The distance between the first and second side walls on the projection plane perpendicular to the width direction increases first and then decreases from top to bottom, with the widest point corresponding to the location of the connecting wall. This structure allows the first and second support sections at the top and bottom to elastically bend outwards when the midsole is subjected to a vertical impact. The connecting wall acts as a connector, restraining the outward expansion of the side walls, thus converting the vertical impact force into controllable lateral elastic deformation of the side walls. Specifically, the first and second support sections, together with the connecting wall, form a first groove and a second groove, which are respectively open from the top wall to the bottom wall and from the bottom wall to the top wall. When subjected to a vertical impact, the approach of the top and bottom walls no longer simply compresses the material, but uses the opening angle of the groove edges to generate a horizontal component force. The first and second side walls, with the connecting wall in the middle as the pivot, produce a controllable contraction and folding movement inwards from the groove. In the initial stage of ground contact, the rotation of the sidewalls and the bending of the groove walls only need to overcome relatively small structural resistance, exhibiting low initial stiffness. This allows for the gentle dissipation of instantaneous impact force through a relatively long folding stroke. As compression increases, the inner walls of the grooves gradually approach each other or even contact each other, or the sidewalls rotate to their limit angles, and the structure enters a compaction stage. At this point, the force mode changes from structural bending to material compression, and the stiffness increases accordingly, entering a high-support mechanical stage. This stage can resist larger impact forces, preventing components from failing due to excessive compression and thus ensuring support safety during movement. Therefore, this characteristic of initial softness followed by hardness ensures both shock absorption under small impacts and strong support under large impact loads, effectively solving the problem of a single material struggling to balance comfort and support.

[0016] Furthermore, the dimensions of the transverse through-hole decrease from top to bottom and then increase, forming an hourglass-shaped structure that is narrow in the middle and wide at both ends. This shape complements the shape of the transverse column. The transverse channel of this shape reserves more space at the two ends where the deformation of the transverse column is the greatest, allowing the first and second support sections to open and fold more fully, thereby extending the effective shock absorption stroke.

[0017] In technical solution two, the top and bottom walls of the transverse through-holes generally extend in the same direction as the upper and lower surfaces of the midsole. In other words, the top and bottom walls of the transverse through-holes also extend horizontally. This, combined with the dimensional changes in the thickness direction of the transverse through-holes, allows the midsole to maintain sufficient support at the location of the transverse through-holes and ensures a continuous and smooth contact between the lower surface of the midsole and the ground. Furthermore, when the midsole bends and deforms, the deformation of the transverse through-holes can naturally compress or stretch in accordance with the overall bending direction of the midsole, avoiding local stress concentration or structural tearing caused by the inconsistency between the hole wall orientation and the bending stress direction.

[0018] In technical solution three, a bottom groove is set on the sole. While not completely cutting off the continuity of the midsole in the length direction, the midsole is divided into two relatively independent support areas in the width direction. When the foot moves on uneven ground or has an inward / outward tendency, the groove allows the left and right lateral columns of the midsole to achieve limited and differentiated compression deformation in the vertical direction, thereby effectively adapting to terrain changes or gait adjustments and improving the dynamic adaptability and wearing stability of the sole.

[0019] In technical solution four, the first support segment is smaller in thickness than the second support segment. Because the lower second support segment is longer and has a greater aspect ratio, it is more prone to bending and deformation during the initial compression phase. This allows it to sensitively absorb the high-frequency impact force at the moment of contact with the ground, providing a softer landing feel. Meanwhile, the upper first support segment is shorter and more stable, enabling it to quickly provide support feedback to the sole of the foot during the later stages of compression, reducing foot sway. Compared to conventional symmetrical structures, this structure significantly optimizes the cushioning efficiency in the first stage of contact while maintaining stability.

[0020] In technical solution five, the circumferential dimensions of the first and second grooves gradually increase from the bottom to the top, giving the grooves a funnel-shaped configuration with an expanding opening. During compression, the involute groove walls do not immediately reach full contact in the early stages of deformation, but rather gradually close upwards from the bottom as the compression depth increases. This working method makes the stiffness change curve of the midsole smoother and more continuous, improving the smoothness of the transition from soft to hard.

[0021] In technical solution six, the bottom surface of the second groove is a stepped shape that descends gradually downwards. When the transverse column is compressed, this stepped structure guides the material to achieve orderly compression deformation, so that the end face of the transverse column has a uniform outward arc-shaped bend at the second groove. This effectively disperses the tensile stress of the smooth ordinary surface, avoids wrinkles or sharp corners caused by excessive deformation, ensures that the transverse column maintains a regular geometric shape during large-scale compression, and prevents the midsole from lateral twisting.

[0022] In technical solution seven, a reinforcing plate is installed on the midsole, penetrating the interior of each transverse column along its length, thus forming a strong physical connection between the transverse columns. Besides serving as a conventional reinforcing component to assist in the rolling and heel lift of the sole, the reinforcing plate can also work synergistically with the transverse columns and transverse channels. Specifically, while the transverse channels give the midsole excellent bending performance, they also disrupt the continuity of the material along its length, causing the transverse columns to be relatively isolated mechanically. Conventional hollow structures, under localized concentrated loads, are prone to excessive lateral tilting or single-point collapse due to the lack of surrounding restraint among independent support units. This solution utilizes the penetrating reinforcing plate to connect the separated transverse columns into a unified force-bearing system. When a single transverse column undergoes the aforementioned shrinkage and folding deformation under pressure, the reinforcing plate, using its own bending stiffness, transfers the load borne at that location along its length to adjacent transverse columns, forcing the surrounding structural units to share the pressure. This connectivity compensates for the structural discontinuity caused by the lateral channels. While retaining the advantages of lightweight midsole and high cushioning travel, it restricts the displacement freedom of the lateral columns in non-preset directions, preventing overall instability caused by lateral shear forces in the hollow structure. Simultaneously, the reinforcing plate, serving as the bottom of the slot, is completely encased within the slot, with its ends connected to the solid material of the midsole, forming a bottom support structure. This allows the reinforcing plate to provide longitudinal torsional stiffness while effectively converging and transmitting the forces from the lateral columns on both sides to the reinforcing plate, and then transitioning from the reinforcing plate to the continuous areas at both ends of the midsole. This avoids potential support discontinuities caused by the slotted structure, maintaining the overall stability of the sole during arch support and forefoot / rearfoot transitions.

[0023] In technical solution eight, the reinforcing plate is set at the connecting wall position of the transverse column. The connecting wall position will not undergo significant deformation. Therefore, the setting position of the reinforcing plate will not affect the bending deformation of the transverse column, thus ensuring the normal realization of the shock absorption function.

[0024] In technical solution nine, the reinforcing plate maintains a preset distance from the midsole sidewall on both sides in the width direction. In other words, the width of the reinforcing plate will not be the same as the width of the midsole. In this way, when the sidewall of the midsole is scratched or the midsole is subjected to large vertical pressure, the reinforcing plate will not directly cut the midsole material or cause stress concentration, thereby improving the durability of the sole of the composite structure and improving the problem of the reinforcing plate being exposed and easily falling off or damaged.

[0025] Technical solution ten provides a shoe incorporating the aforementioned cushioning and support sole. The upper secures the foot to the sole with this specific structure, ensuring that the foot's center of force accurately aligns with the various lateral column functional areas of the midsole. The combination of the upper and sole transforms the structural advantages of the sole into overall shoe performance, providing continuous and stable support and protection for the wearer during running or jumping, thus reducing the risk of sports injuries.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and accompanying drawings of this invention is for distinguishing different objects and not for describing a specific order.

[0031] Unless otherwise expressly defined, in the claims, description, and accompanying drawings of this invention, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" to indicate orientation or positional relationships is based on the orientation and positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0032] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0033] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0034] Example 1 This invention relates to a shoe, comprising a sole and an upper attached to the sole. The upper is fixedly connected to the sole using conventional shoemaking processes such as bonding, sewing, hot pressing, or one-piece molding to form a complete shoe. The upper is typically made of fabric, leather, synthetic materials, or combinations thereof, and is used to wrap the user's foot. When the upper is attached to the sole, the upper and sole work together. The upper is responsible for fixing the foot's position, preventing relative slippage of the foot within the shoe during exercise, and effectively transmitting foot pressure to the sole. The sole provides excellent cushioning and dynamic support, thereby improving the wearer's athletic performance and comfort.

[0035] Reference Figure 1 and Figure 2 The sole comprises a midsole 100, a reinforcing plate 200, and an outsole 300. Before describing the structure of the sole, it is necessary to first explain the directional definitions in the specification and claims of this invention. Since the sole is used in a shoe, it corresponds to the outer and inner sides of the human foot and can be defined in a left-right direction. For example, for the left foot, the left side is the outer side and the right side is the inner side. Furthermore, the sole also defines a front-back direction and a vertical direction; the front-back direction is the length direction of the sole, and the vertical direction is the thickness direction of the sole.

[0036] The structure of the shoe sole will now be described in detail.

[0037] The midsole 100 of the shoe sole has a plurality of transverse through holes 110 extending along the width direction from front to back. The portion between adjacent transverse through holes 110 forms a transverse column 120 extending along the width direction. The end face of the transverse column 120 in the width direction includes a top wall 121, a bottom wall 122, a first side wall 123, a second side wall 124, and a connecting wall 125. The top wall 121 and the bottom wall 122 are arranged along the thickness direction, and the first side wall 123 and the second side wall 124 are arranged along the length direction, with their ends in the thickness direction connected to the top wall 121 and the bottom wall 122, respectively. The connecting wall 125 connects the first side wall 123 and the second side wall 124 along the length direction. The first side wall 123... 23. The second side wall 124 is divided by the connecting wall 125 and has a first support section 126 and a second support section 127 along the thickness direction. The two first support sections 126, the top wall 121 and the connecting wall 125 enclose a first groove 128 that is recessed along the width direction. The two second support sections 127, the bottom wall 122 and the connecting wall 125 enclose a second groove 129 that is recessed along the width direction. The first groove 128 and the second groove 129 are arranged along the thickness direction. The distance between the first side wall 123 and the second side wall 124 on the projection plane perpendicular to the width direction increases from top to bottom and then decreases. The position where the distance decreases is consistent with the position of the connecting wall 125.

[0038] Specifically, refer to Figure 1 and Figure 2 The midsole 100 of the shoe sole can be made of conventional foam materials, such as ethylene-vinyl acetate copolymer (EVA), thermoplastic polyurethane (TPU), expanded thermoplastic polyurethane (E-TPU), or nylon elastomer (PEBA), which are elastic materials with good cushioning and rebound properties. The shape of the midsole 100 is the same as that of a conventional shoe sole to correspond to the shape and structure of the human foot, and the top surface of the midsole 100 forms the footbed for the foot to contact.

[0039] The midsole 100 has multiple transverse through-holes 110 extending along its length and width. These transverse through-holes 110 can be considered as being formed by hollowing out the midsole 100 along its width. The portion left after hollowing out, that is, the portion between adjacent transverse through-holes 110, forms transverse pillars 120, which also extend along the width. In this embodiment, transverse through-holes 110 are provided in the forefoot area, arch area, and heel area of ​​the midsole 100. The dimensions of the transverse through-holes 110 and transverse pillars 120 are adapted to the thickness of the midsole 100 at their respective locations. That is, in the forefoot area where the midsole 100 is thinner, the dimensions of the transverse through-holes 110 and transverse pillars 120 are smaller, and in the heel area where the midsole 100 is thicker, the dimensions of the transverse through-holes 110 and transverse pillars 120 are larger. Here, the dimensions refer to the area of ​​the shape of the transverse through-holes 110 and transverse pillars 120 on the projection plane perpendicular to the width direction. In this embodiment, the transverse through holes 110 and transverse pillars 120 on the midsole 100 are arranged in sequence, that is, the rear side of a transverse through hole 110 is a transverse pillar 120, and the rear side of a transverse pillar 120 is a transverse through hole 110.

[0040] Reference Figure 1 and Figure 2The end face of the transverse column 120 in the width direction can be considered as part of the two side walls in the width direction of the base 100. The end face of the transverse column 120 includes a top wall 121, a bottom wall 122, a first side wall 123, a second side wall 124, and a connecting wall 125. Here, "wall" can be considered as a structure that is slightly raised relative to the nearby surface. The top wall 121, the first side wall 123, the bottom wall 122, and the second side wall 124 are connected end to end to form a structure that is approximately hexagonal in shape on a projection plane perpendicular to the width direction. The connecting wall 125 is located inside the hexagonal structure and extends along the length direction to connect with the first side wall 123 and the second side wall 124. The top wall 121 is located at the top of the hexagonal structure, and the bottom wall 122 is located at the bottom of the hexagonal structure. The top wall 121 is roughly flush with the bottom surface of the footbed formed by the top surface of the midsole 100. Typically, the midsole 100 extends slightly upwards at the outer edge of the footbed to create a footbed structure with better circumferential support. The bottom wall 122 is slightly higher than the bottom surface of the midsole 100. The first side wall 123 and the second side wall 124 both extend along the thickness direction, but they do not extend in a straight line. The term "extending along the thickness direction" here is only used to describe their extension trend. Both the first side wall 123 and the second side wall 124 include a first support section 126 and a second support section 127. The upper end of the first support section 126 of the first side wall 123 is connected to the front end of the top wall 121, the lower end of the first support section 126 is connected to the upper end of the second support section 127, and the lower end of the second support section 127 is connected to the front end of the bottom wall 122. Similarly, the upper end of the first support section 126 of the second side wall 124 is connected to the rear end of the top wall 121, the lower end of the first support section 126 is connected to the upper end of the second support section 127, and the lower end of the second support section 127 is connected to the rear end of the bottom wall 122. Furthermore, the first support segment 126 of the first sidewall 123 extends downward and forward at an angle, and the second support segment 127 extends downward and backward at an angle. Similarly, the first support segment 126 of the second sidewall 124 extends downward and backward at an angle, and the second support segment 127 extends downward and forward at an angle. This results in the distance between the first sidewall 123 and the second sidewall 124 along the length direction on a projection plane perpendicular to the width direction, increasing from top to bottom and then decreasing. In this embodiment, the dimension of the first support segment 126 in the thickness direction is smaller than the dimension of the second support segment 127 in the thickness direction; that is, the first support segment 126 is shorter than the second support segment 127.

[0041] Reference Figure 1The connecting wall 125 is positioned at the junction of the first support section 126 and the second support section 127. That is, the front and rear ends of the connecting wall 125 connect to the junctions of the first support section 126 and the second support section 127 on the first side wall 123 and the second side wall 124, respectively. Using the connecting wall 125 as a boundary, the two first support sections 126, the top wall 121, and the connecting wall 125 enclose a first groove 128, and the two second support sections 127, the bottom wall 122, and the connecting wall 125 enclose a second groove 129. The depth of the first groove 128 can be considered to gradually increase upwards from the connecting wall 125, reaching its deepest point at the top wall 121. The depth of the second groove 129 can be considered to gradually increase downwards from the connecting wall 125, reaching its deepest point at the bottom wall 122. Simultaneously, the portion of the groove wall formed by the first support section 126 and the second support section 127 that encloses the first groove 128 and the second groove 129 has a certain angle of inclination. Therefore, the circumferential dimensions of the first groove 128 and the second groove 129 gradually increase from the bottom to the top of the groove.

[0042] Furthermore, referring to Figure 1 and Figure 2 A stepped structure 1210 is provided on the bottom surface of the second groove 129. This stepped structure 1210 descends in a step-like manner, starting from the connecting wall 125. Specifically, the stepped structure 1210 is formed on the bottom surface of the second groove 129 and is located between the connecting wall 125 and the bottom wall 122. The bottom surface of the groove is not a smooth slope, but rather consists of several stepped surfaces arranged sequentially along the thickness direction and alternating vertical surfaces connecting adjacent stepped surfaces. On a projection plane perpendicular to the length direction, the outline of this stepped groove bottom surface appears as a broken line, extending to the bottom wall 122.

[0043] Reference Figure 1 and Figure 2The transverse through-hole 110, projected onto a plane perpendicular to its width, decreases in size from top to bottom along its length, then increases. The position where its size increases coincides with the position of the connecting wall 125 in the adjacent transverse column 120. Specifically, since the transverse through-hole 110 is formed by the gap between two adjacent transverse columns 120, its shape is defined by the morphology of the opposite sides of the two adjacent transverse columns 120. As previously stated, the distance between the transverse column 120 and the first side wall 123 and the second side wall 124 (i.e., the solid thickness of the transverse column 120 along its length) reaches its maximum at the position of the connecting wall 125. This means that the solid portions of the two adjacent transverse columns 120 are closest to each other at the height of the connecting wall 125. Correspondingly, the span (i.e., the aperture) of the transverse through-hole 110 sandwiched between them is minimized at this position along its length. As a result, the top and bottom of the transverse through hole 110 are relatively wide due to the shrinkage of the thickness of the transverse column 120, while the middle position is relatively narrow, presenting an hourglass-like outline that is narrow in the middle and open at both ends on the projection plane perpendicular to the width direction.

[0044] Furthermore, the top and bottom walls of the transverse through-hole 110 extend in the thickness direction in line with the upper and lower surfaces of the midsole 100 at their respective locations. In other words, the top and bottom walls of the transverse through-hole 110 are not necessarily horizontal planes, but rather extend along the overall shape curve of the midsole 100. For example, in the forefoot upturned area of ​​the midsole 100, the bottom wall of the transverse through-hole 110 will correspondingly exhibit an upward curvature; in the arch area of ​​the midsole 100, the top and bottom walls will also conform to the raised shape of the arch.

[0045] Furthermore, the bottom of the midsole 100 is recessed at the midpoint of its width direction along its length direction, forming a bottom groove 1211 that is closed at both ends; and the length of the bottom groove 1211 corresponds at least to all the transverse pillars 120. A transverse through-hole 110 forms an opening on the side wall of the bottom groove 1211 with the same shape as the transverse through-hole 110 projected onto a plane perpendicular to its width direction. In this embodiment, the groove wall of the bottom groove 1211 extending along its length direction is zigzag-shaped on a projection plane perpendicular to its thickness direction. Specifically, the bottom groove 1211 is located in the central axis region of the bottom surface of the midsole 100, and its depth direction at least covers the shape of the transverse through-hole 110 projected onto a plane perpendicular to its width direction, thereby allowing the transverse through-hole 110 to form an opening on the side wall of the bottom groove 1211, and the shape of the opening is the same as the shape of the transverse through-hole 110. The fact that the bottom groove 1211 is closed at both ends means that it does not extend to the very front and rear ends of the midsole 100, but rather retains the solid midsole 100 material connecting the left and right sides at both ends, thus ensuring the integrity of the sole's structure. Furthermore, the bottom groove wall 1212 is zigzag-shaped, meaning that the inner wall surface forming the left and right boundaries of the bottom groove 1211 is not a straight plane, but rather composed of several angled folds connected end to end.

[0046] In addition, the outsole may also include an outsole 300. The outsole 300 is fixed to the bottom surface of the midsole 100. Specifically, the outsole 300 is typically made of a material with a high coefficient of friction, such as abrasion-resistant rubber, to provide good grip and abrasion resistance. In this embodiment, the shape of the outsole 300 is adapted to the ground contact profile of the bottom of the midsole 100, that is, the outsole 300 mainly conforms to the lower surface of the walls of the midsole 100 of each transverse column 120. Given that the bottom of the midsole 100 has a bottom groove 1211 in the center and the bottom of the groove is a reinforcing plate 200, the outsole 300 preferably avoids the area of ​​the bottom groove 1211, thereby forming a left and right separated layout in the width direction of the outsole 300, corresponding to the bottom surfaces of the transverse columns 120 on both sides of the bottom groove 1211 respectively. In addition, the bottom surface of the outsole 300 is also provided with anti-slip texture or lug structure to further enhance the anti-slip effect and propulsion efficiency of the outsole during movement.

[0047] Example 2 The difference between Example 2 and Example 1 is that a reinforcing plate 200 is also provided on the midsole 100.

[0048] Reference Figure 3 and Figure 4The reinforcing plate 200 extends along both its length and width, penetrating each of the transverse columns 120. The position of the reinforcing plate 200 at each transverse column 120 corresponds to the position of the connecting wall 125 of that transverse column 120. Furthermore, the reinforcing plate 200 has a predetermined distance between its two edges in the width direction and the two side walls in the width direction of the midsole 100. Specifically, the reinforcing plate 200 is made of a rigid material with higher hardness and bending stiffness than the foam material of the midsole 100, such as nylon, rigid thermoplastic polyurethane (TPU), carbon fiber composite material, or glass fiber composite material, to provide sufficient structural support and torsional resistance. The reinforcing plate 200 has a plate-like structure that undulates with the arch curve of the midsole 100 and continuously passes through each transverse column 120 in the length direction. The position of the reinforcing plate 200 coincides precisely with the position of the connecting wall 125 on the transverse column 120; that is, in the portion where the reinforcing plate 200 passes through the transverse column 120, the orientation of the reinforcing plate 200 is essentially the same as the orientation of the connecting wall 125. The reinforcing plate 200 has a total width dimension that is smaller than the width dimension of the midsole 100 at the corresponding position, so that the left and right edges of the reinforcing plate 200 are recessed within the side contour line of the midsole 100.

[0049] In addition, refer to Figure 5 The bottom of the bottom slot 1211 is a reinforcing plate 200. Specifically, the reinforcing plate 200 is provided at the middle position in the depth direction of the bottom slot 1211, and the middle area of ​​the reinforcing plate 200 is exposed from the position of the bottom slot 1211, so that the reinforcing plate 200 constitutes the physical bottom surface of the bottom slot 1211. In at least one embodiment, the present invention provides a shock-absorbing support sole, wherein the midsole 100 is provided with a plurality of transverse through holes 110 extending along the width direction from front to back, and the portion between adjacent transverse through holes 110 forms a transverse column 120 extending along the width direction; the end face of the transverse column 120 in the width direction includes a top wall 121, a bottom wall 122, a first side wall 123, a second side wall 124, and a connecting wall 125; the top wall 121 and the bottom wall 122 are arranged along the thickness direction, and the first side wall 123 and the second side wall 124 are arranged along the length direction, and their two ends in the thickness direction are respectively connected to the top wall 121 and the bottom wall 122; the connecting wall 125 connects the first side wall 123 and the second side wall 124 along the length direction; the first side wall 123 and the second side wall 124 are uniformly shaped along the thickness direction with the connecting wall 125 as the boundary. The structure comprises a first support section 126 and a second support section 127; the two first support sections 126, the top wall 121, and the connecting wall 125 enclose a first groove 128 recessed along the width direction, and the two second support sections 127, the bottom wall 122, and the connecting wall 125 enclose a second groove 129 recessed along the width direction; the first groove 128 and the second groove 129 are arranged along the thickness direction; the distance between the first side wall 123 and the second side wall 124 on the projection plane perpendicular to the width direction increases from top to bottom and then decreases, and the position where the distance decreases is consistent with the position of the connecting wall 125; the dimension of the transverse through hole 110 on the projection plane perpendicular to the width direction along the length direction decreases from top to bottom and then increases, and the position where the dimension increases is consistent with the position of the connecting wall 125 in the adjacent transverse column 120.

[0050] The midsole 100 of this cushioning support sole has transverse channels, and transverse columns 120 are formed between these channels. By making the midsole 100 continuous in the width direction, its weight is reduced, while also allowing it to have multiple easily bendable sections in the length direction, thereby improving the wearing comfort of the midsole 100. The transverse columns 120 play a key role in cushioning support. Because the transverse channels significantly reduce the overall structural strength of the midsole 100, the cushioning support performance of the midsole 100 is concentrated at the position of the transverse columns 120. Therefore, the transverse columns 120 need to have more efficient cushioning support performance than a conventional midsole 100 structure. In this design, a top wall 121, a bottom wall 122, two side walls, and a connecting wall 125 are provided at the end face of the transverse columns 120. The distance between the first side wall 123 and the second side wall 124 on the projection plane perpendicular to the width direction shows a trend of first increasing and then decreasing from top to bottom, and the widest position corresponds to the location of the connecting wall 125. This structure allows the first and second support sections 127 to elastically bend outwards when the midsole 100 is subjected to a vertical impact. The connecting wall 125 acts as a connector, restraining the outward expansion of the side walls, thereby converting the vertical impact force into controllable lateral elastic deformation of the side walls. Specifically, the first support section 126, the second support section 127, and the connecting wall 125 cooperate to form the first groove 128 and the second groove 129, which are respectively open from the top wall to the bottom wall and from the bottom wall to the top wall. When subjected to a vertical impact, the approach of the top wall and the bottom wall no longer simply compresses the material, but uses the opening angle of the groove edge to generate a horizontal component force. The first side wall 123 and the second side wall 124 generate a controllable contraction and folding movement inwards from the middle connecting wall 125. In the initial stage of ground contact, the rotation of the sidewalls and the bending of the groove walls only need to overcome relatively small structural resistance, exhibiting low initial stiffness. This allows for the gentle dissipation of instantaneous impact force through a relatively long folding stroke. As compression increases, the inner walls of the grooves gradually approach each other or even contact each other, or the sidewalls rotate to their limit angles, and the structure enters a compaction stage. At this point, the force mode changes from structural bending to material compression, and the stiffness increases accordingly, entering a high-support mechanical stage. This stage can resist larger impact forces, preventing components from failing due to excessive compression and thus ensuring support safety during movement. Therefore, this characteristic of initial softness followed by hardness ensures both shock absorption under small impacts and strong support under large impact loads, effectively solving the problem of a single material struggling to balance comfort and support.Furthermore, the dimensions of the transverse through-hole 110 decrease from top to bottom along its length, forming an hourglass-shaped structure that is narrow in the middle and wide at both ends. This shape complements the shape of the transverse column 120. The transverse channel of this shape provides a larger space allowance at the two ends of the transverse column 120 where the deformation amplitude is the greatest, allowing the first support section 126 and the second support section 127 to perform more fully opening and folding movements, thereby extending the effective shock absorption stroke.

[0051] In at least one embodiment, the top and bottom walls of the transverse through-hole 110 extend in the thickness direction in line with the upper and lower surfaces of the midsole 100 at the same location.

[0052] The top and bottom walls of the transverse through-hole 110 generally extend in the same direction as the upper and lower surfaces of the midsole 100. In other words, the top and bottom walls of the transverse through-hole 110 also extend horizontally. This, combined with the dimensional changes in the thickness direction of the transverse through-hole 110, allows the midsole 100 to maintain sufficient support at the location of the transverse through-hole 110 and ensures a continuous and smooth contact between the lower surface of the midsole 100 and the ground. Furthermore, when the midsole 100 bends and deforms, the deformation of the transverse through-hole 110 can naturally compress or stretch in accordance with the overall bending direction of the midsole 100, avoiding local stress concentration or structural tearing caused by the inconsistency between the hole wall orientation and the bending stress direction.

[0053] In at least one embodiment, the bottom of the midsole 100 is recessed at the middle position in the width direction and has a bottom groove 1211 that is closed at both ends in the length direction; the length range of the bottom groove 1211 corresponds to at least all the transverse columns 120; the transverse through hole 110 forms an opening on the side groove wall of the bottom groove 1211 with the same shape as the transverse through hole 110 on the projection plane perpendicular to the width direction.

[0054] A bottom groove 1211 is provided on the sole, which divides the midsole 100 into two relatively independent support areas in the width direction without completely cutting off the continuity of the midsole 100 in the length direction. When the foot moves on uneven ground or has an inward / outward tendency, the groove allows the left and right lateral columns 120 of the midsole 100 to achieve limited and differentiated compression deformation in the vertical direction, thereby effectively adapting to terrain changes or gait adjustments and improving the dynamic adaptability and wearing stability of the sole.

[0055] In at least one embodiment, the dimension of the first support segment 126 in the thickness direction is smaller than the dimension of the second support segment 127 in the thickness direction.

[0056] The first support segment 126 is smaller in thickness than the second support segment 127. Because the lower second support segment 127 is longer and has a greater aspect ratio, it is more prone to bending and deformation in the initial stage of compression. This allows it to sensitively absorb the high-frequency impact force at the moment of contact with the ground, providing a softer landing feel. The upper first support segment 126 is shorter and has a relatively stable structure, enabling it to quickly provide support feedback to the sole of the foot in the later stages of compression, reducing foot sway. Compared to conventional symmetrical structures, this structure significantly optimizes the cushioning efficiency in the first stage of contact while maintaining stability.

[0057] In at least one embodiment, the circumferential dimensions of the first groove 128 and the second groove 129 gradually increase from the bottom of the groove to the top of the groove.

[0058] The circumferential dimensions of the first groove 128 and the second groove 129 gradually increase from the bottom to the top, giving the grooves a funnel-shaped configuration with an expanding opening. During compression, the involute groove walls do not immediately reach full contact in the early stages of deformation, but gradually close upwards from the bottom as the compression depth increases. This working method makes the stiffness change curve of the midsole 100 smoother and more continuous, improving the smoothness of the transition from soft to hard.

[0059] In at least one embodiment, the bottom surface of the second groove 129 is in a stepped shape that descends gradually from the connecting wall 125.

[0060] The bottom surface of the second groove 129 is stepped, descending gradually downwards. When the transverse column 120 is compressed, this stepped structure guides the material to achieve orderly compression deformation, so that the end face of the transverse column 120 has a uniform outward arc-shaped bend at the second groove 129. This effectively disperses the tensile stress of the smooth ordinary surface, avoids wrinkles or sharp corners caused by excessive deformation, and ensures that the transverse column 120 maintains a regular geometric shape during large-scale compression, preventing the midsole 100 from laterally twisting.

[0061] In at least one embodiment, a reinforcing plate 200 is also included, which extends along the length and width directions and penetrates each transverse column 120; the reinforcing plate 200 forms the bottom of the bottom slot 1211.

[0062] A reinforcing plate 200 is installed on the midsole 100, penetrating the interior of each transverse column 120 along its length, thus forming a strong physical connection between the transverse columns 120. Besides serving as a conventional reinforcing component to assist in the rolling and heel lift of the sole, the reinforcing plate 200 also works synergistically with the structure of the transverse columns 120 and the transverse channels. Specifically, while the transverse channels give the midsole 100 excellent bending performance, they also disrupt the continuity of the material along its length, causing the transverse columns 120 to be relatively isolated mechanically. Conventional hollow structures, under localized concentrated loads, are prone to excessive lateral tilting or single-point collapse due to the lack of peripheral restraint among independent support units. This solution utilizes the through-through reinforcing plate 200 to connect the separated transverse columns 120 into a unified force-bearing system. When a single transverse column 120 undergoes the aforementioned shrinkage and folding deformation due to compression, the reinforcing plate 200 utilizes its own bending stiffness to transfer the load borne at that location along its length to adjacent transverse columns 120, forcing surrounding structural units to share the pressure. This connectivity compensates for the structural discontinuity caused by the transverse channels, while retaining the lightweight and high shock-absorbing stroke advantages of the midsole 100, it restricts the displacement freedom of the transverse columns 120 in non-preset directions, preventing overall instability of the hollow structure due to lateral shear forces. Simultaneously, the reinforcing plate 200, serving as the bottom of the slot, is completely encased within the slot, with its two ends connected to the solid material of the midsole 100, forming a bottom support structure. This allows the reinforcing plate 200 to effectively concentrate and transmit the force from the left and right transverse columns 120 to the reinforcing plate 200 while providing longitudinal torsional stiffness. The force then transitions from the reinforcing plate 200 to the continuous areas at both ends of the midsole 100, thus avoiding the support force discontinuity that may be caused by the slotted structure and maintaining the overall stability of the sole during arch support and forefoot / rearfoot transition.

[0063] In at least one embodiment, the position of the reinforcing plate 200 at each transverse column 120 corresponds to the position of the connecting wall 125 of the transverse column 120.

[0064] The reinforcing plate 200 is installed at the connecting wall 125 of the transverse column 120. The connecting wall 125 will not undergo significant deformation. Therefore, the installation position of the reinforcing plate 200 will not affect the bending deformation of the transverse column 120, thus ensuring the normal realization of the shock absorption function.

[0065] In at least one embodiment, the reinforcing plate 200 has a predetermined distance between its two sides in the width direction and the two side walls of the midsole 100 in the width direction.

[0066] The reinforcing plate 200 maintains a preset distance from the side wall of the midsole 100 on both sides in the width direction. That is, the width of the reinforcing plate 200 is not the same as the width of the midsole 100. In this way, when the side wall of the midsole 100 is scratched or the midsole 100 is subjected to large vertical pressure, the reinforcing plate 200 will not directly cut the material of the midsole 100 or cause stress concentration, thereby improving the durability of the sole of the composite structure and improving the problem of the reinforcing plate 200 being exposed and easily falling off or damaged.

[0067] In at least one embodiment, a shoe is also provided, which includes an upper and a cushioning support sole of any of the above embodiments, the upper being attached to the sole.

[0068] This shoe uses an upper to secure the foot to the sole with its specific structure, allowing the foot's center of force to accurately align with the various lateral pillars 120 of the midsole. The combination of the upper and sole transforms the structural advantages of the sole into overall shoe performance, providing the wearer with continuous and stable support and protection during running or jumping, thus reducing the risk of sports injuries.
