Description

Technical Field

[0001] This invention relates to the field of footwear and apparel, and specifically to a breathable and breathing pad for shoe soles and a breathable and breathing shoe sole. Background Technology

[0002] Shoes are an indispensable part of people's daily lives. The creation and development of shoes are inseparable from the natural environment. With the development of technology, the functions of shoes are becoming more and more perfect. In order to enhance the breathability of shoes, especially sports shoes such as running shoes, it is necessary to design shoes with multi-dimensional breathability. Usually, breathable fabrics are used as the upper, but the breathability of the sole, which occupies a large area, is also crucial.

[0003] To address the aforementioned issues, Chinese invention patent CN119385374A discloses a breathable device for shoe soles, comprising a pad and a waterproof and breathable fabric covering the surface of the pad. The pad surface has multiple protrusions, each containing multiple breathable holes. The periphery of the waterproof and breathable fabric has multiple circular holes, and a washer is stacked on the periphery of the fabric, integrally formed with the pad through the circular holes. The protrusions form interconnected grooves for secondary injection molding and bonding of the waterproof and breathable fabric. The bottom of the grooves has multiple protrusions for abutting the waterproof and breathable fabric. The pad and washer are integrally injection molded from TPU material. Multiple inclined plates are provided within the protrusions, forming the breathable holes between the inclined plates. The pad thickness is 1-3 mm. A method for preparing a breathable device for shoe soles includes the following steps: 1) Placing TPU raw material into the lower mold cavity of mold A, closing the upper mold of mold A, heating and molding, cooling and opening the mold to obtain a semi-finished inner ring component of the breathable device, wherein the protrusions form a groove structure and all grooves are interconnected to form a mesh; 2) Taking a piece of waterproof and breathable fabric, punching holes in the waterproof and breathable fabric, the round holes of the waterproof fabric are adapted to the periphery of the inner ring component and arranged to form a ring; 3) Placing the inner ring component obtained in the previous step into the lower mold cavity of mold B, leaving a gap between the inner ring component and the periphery of the mold cavity, hanging the waterproof and breathable fabric on the upper mold of mold B, closing the upper mold of mold B, injecting TPU material into the mold cavity of mold B, and bonding the inner ring component to the waterproof and breathable fabric integrally through the newly injected TPU material; 4) Cooling, opening the mold, and cutting off the excess waterproof and breathable fabric along the edge of the breathable device to obtain the breathable device. The upper mold of mold B has an annular groove on its bottom surface that aligns with the periphery of the lower mold. Newly injected TPU material can flow into the annular groove through the circular holes in the waterproof and breathable fabric. The lower molds of molds A and B each have corresponding positioning pins within their respective cavities. The inner ring component has positioning holes that mate with the positioning pins. A shoe sole includes a midsole with a groove on its upper surface. Through holes corresponding to the ventilation holes are provided through the bottom of the groove. An outsole is bonded to the bottom of the midsole. A waterproof and breathable shoe includes an upper and a sole with a ventilation device installed. The upper is connected to the upper end of the sole.

[0004] This invention patent solves the problem of breathability and waterproofing of shoe soles to a certain extent. However, on roads with a lot of water, water can easily splash from the holes in the sole to the lower surface of the waterproof and breathable parts of the waterproof and breathable membrane. Alternatively, water vapor may condense on the lower surface of the waterproof and breathable parts of the membrane, forming a water layer that blocks the vents and severely affects the breathability of the waterproof and breathable parts. Furthermore, the water layer that condenses over a long period of time can easily form moisture that enters the shoe, further affecting the waterproof performance of the membrane.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0006] One objective of this invention is to provide a breathable breathing pad for shoe soles that can shake off a waterproof and breathable membrane layer, ensuring breathability and waterproofness.

[0007] A second objective of this invention is to provide a breathable, breathable sole that can shake off the waterproof and breathable membrane layer, ensuring both breathability and waterproofness.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A breathable insole pad includes a main body; the main body includes a substrate layer on top of the main body of the sole and a waterproof and breathable membrane layer disposed on the substrate layer; the substrate layer has substrate venting holes, an upward-facing upper surface and a downward-facing lower surface facing the main body of the sole; the waterproof and breathable membrane layer is at least correspondingly disposed above the substrate venting holes; the substrate venting holes include a plurality of mesh holes, adjacent mesh holes being separated by a grid frame; the waterproof and breathable membrane layer has a corresponding waterproof and breathable portion above the grid frame, the waterproof and breathable membrane layer is equipped with a vibrating component that drives the waterproof and breathable portion to vibrate to shake off adhering water, and there is a vibration space between the waterproof and breathable portion and the grid frame for the waterproof and breathable portion to move downward when vibrating; the vibrating component is an elastic memory sheet that drives the waterproof and breathable portion to swing up and down.

[0010] The vibrating component includes an annular memory elastic sheet surrounding the waterproof and breathable part. The center of the annular memory elastic sheet is an elastic sheet opening corresponding to the waterproof and breathable part. The annular memory elastic sheet has an inner edge in the inner circle and an outer edge in the outer circle. The inner edge is higher than the outer edge. The annular memory elastic sheet gradually slopes downward and outward from the inner edge to the outer edge. The annular memory elastic sheet is connected to the waterproof and breathable membrane layer and / or the base layer.

[0011] The angle of inclination of the line connecting the outer edge to the inner edge relative to the plane containing the outer edge is 5-35°;

[0012] The cross-section of the annular memory elastic sheet extends in a straight line from the outer edge to the inner edge; or, the cross-section of the annular memory elastic sheet arches outward to form an arched curved portion; or, the cross-section of the annular memory elastic sheet arches outward at the top and curves inward at the bottom to form an S-shaped curved portion.

[0013] The outer edge has two or more gaps.

[0014] Three or more notches are evenly arranged along the outer edge.

[0015] The waterproof and breathable membrane layer has an annular connection portion that connects to the annular memory elastic sheet, and the annular connection portion is set around the waterproof and breathable portion.

[0016] The annular memory elastic sheet is fixedly connected to the annular connecting part and stretches the waterproof and breathable part outward to form a waterproof and breathable support part.

[0017] The annular memory elastic sheet is attached to the lower or upper surface of the waterproof and breathable membrane layer.

[0018] The annular memory elastic sheet and the annular connecting part are connected together by adhesive bonding.

[0019] The ring-shaped memory elastic sheet is made of metal or resin.

[0020] The substrate layer has elastic sheet limiting grooves that limit the position of the annular memory elastic sheet, and the elastic sheet limiting grooves are arranged around the vent holes of the substrate.

[0021] The elastic sheet limiting groove has an inner groove ring close to the vent hole of the substrate and an outer groove ring away from the vent hole of the substrate. The inner edge of the annular memory elastic sheet protrudes further inward than the inner groove ring, and the inner groove ring is higher than the grid frame.

[0022] The height of the annular memory elastic sheet is greater than the depth of the elastic sheet limiting groove, and the upper end of the annular memory elastic sheet protrudes beyond the upper end of the elastic sheet limiting groove.

[0023] The waterproof and breathable membrane layer has a bending buffer that bends downward and sinks into the elastic sheet limiting groove, and the bending buffer is set around the annular memory elastic sheet.

[0024] The waterproof and breathable membrane layer also includes a connection area that connects to the substrate layer, and the connection area is set around the bending buffer zone.

[0025] The connection area is bonded to the upper surface of the substrate layer by gluing or hot pressing.

[0026] The substrate layer has multiple substrate breathable pores. The entire waterproof and breathable membrane layer is covered on the upper surface of the substrate layer. The waterproof and breathable membrane layer has multiple waterproof and breathable parts, which are located above the substrate breathable pores one by one. The connecting area separates the adjacent waterproof and breathable parts.

[0027] A breathable and breathing sole further includes a sole body for mounting a breathable and breathing pad for the sole, the sole body having a sole through hole corresponding to the breathable through hole of the substrate.

[0028] Multiple outsole holes are formed on the main body of the sole, and correspond one-to-one with multiple base plate ventilation holes; the base plate layer is fixed to the upper surface of the main body of the sole, and a positioning groove is formed on the upper surface of the main body of the sole to accommodate and position the base plate layer.

[0029] The substrate ventilation holes have a downward-protruding substrate protrusion that extends downward into the shoe sole ventilation holes.

[0030] By adopting the above technical solution, the breathable breathing pad for shoe soles of the present invention breaks through the traditional structural form of breathable breathing pads for shoe soles. In actual installation and use, it is installed on the main body of the shoe sole with sole holes. The waterproof and breathable parts and the breathable holes of the base plate correspond to the sole holes. The three can connect the inside of the shoe with the outside air to form a smooth breathable channel inside the shoe during wear, ensuring a high-efficiency breathability. At the same time, the waterproof and breathable membrane layer can isolate external liquids such as water while allowing breathability, preventing liquids from entering the shoe and affecting wearing comfort. On this basis, in order to solve the problem of water layer attached to the waterproof and breathable parts blocking the waterproof and breathable parts and affecting breathability, the present invention adds an elastic memory sheet as a vibration component. The elastic memory sheet switches between two states: downward deformation when subjected to stepping force and upward return to its original shape when not subjected to stepping force. This drives the waterproof and breathable parts to move up and down to achieve vibration, thereby shaking off the water layer attached to the lower surface of the waterproof and breathable parts. This can prevent the external water layer from blocking the waterproof and breathable parts and affecting breathability and moisture seeping into the shoe. The vibration space ensures that the vibration of the elastic memory film and the waterproof and breathable parts is undisturbed. Compared with the prior art, the breathable breathing pad for shoe soles of the present invention has the advantages of being able to shake off the water layer of the waterproof and breathable membrane, ensuring breathability and waterproofness.

[0031] This invention relates to a breathable sole that breaks away from the traditional construction of breathable soles. During installation and use, the invention can be connected to the upper to form a complete shoe. The waterproof and breathable parts and the base plate's breathable holes correspond to the sole's holes, allowing the shoe's interior to connect with the outside air, creating a smooth breathing channel during wear and ensuring efficient breathability. Furthermore, the waterproof and breathable membrane layer, while allowing breathability, isolates external liquids such as water, preventing liquid from entering the shoe and affecting comfort. To address the issue of water layers clogging the waterproof and breathable parts, this invention adds an elastic memory film as a vibration component. The elastic memory film switches between two states: downward deformation under pressure and upward return to its original shape when no pressure is applied. This drives the waterproof and breathable parts to reciprocate, vibrating to shake off water layers adhering to the lower surface of the waterproof and breathable parts. This prevents external water layers from clogging the waterproof and breathable parts and causing moisture to seep into the shoe. The vibration space ensures that the vibration of the elastic memory film and the waterproof and breathable parts is undisturbed. Compared with the prior art, the breathable sole of the present invention has the advantages of being able to shake off the water layer of the waterproof and breathable membrane, ensuring breathability and waterproofness.

[0054] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0055] The present invention provides a breathable and breathing pad for shoe soles, such as... Figure 1-18 As shown, the device includes a breathing pad body 1; the breathing pad body 1 includes a substrate layer 11 located on the upper part of the sole body 2 and a waterproof and breathable membrane layer 12 disposed on the substrate layer 11; the substrate layer 11 has substrate breathable holes 111, and the substrate layer 11 has an upward-facing upper substrate surface and a downward-facing substrate lower surface facing the sole body 2; the waterproof and breathable membrane layer 12 is at least correspondingly disposed above the substrate breathable holes 111; in this embodiment, the substrate breathable holes 111 include a plurality of mesh holes 1111, and adjacent mesh holes 1111 are separated by a grid frame 1112; the breathability can also be further enhanced by removing the grid frame 1112 and only setting the mesh hole 1111 structure, and is not limited to this.

[0056] The waterproof and breathable membrane layer 12 has a corresponding waterproof and breathable portion 121 located above the grid frame 1112. The waterproof and breathable membrane layer 12 is equipped with a vibrating component 3 that drives the waterproof and breathable portion 121 to vibrate and shake off the attached water. In this application, the water refers to moisture or water film.

[0057] A vibration space 13 is provided between the waterproof and breathable part 121 and the mesh frame 1112, allowing the waterproof and breathable part 121 to move downwards when it vibrates; the vibration component 3 is an elastic memory sheet that drives the waterproof and breathable part 121 to swing up and down. In actual installation and use, this invention is installed on the sole body 2 with sole holes 21. The waterproof and breathable part 121 and the base plate breathable holes 111 correspond to the sole holes 21. The three can connect the inside of the shoe with the outside air to form a smooth breathable channel inside the shoe during wear, ensuring a high-efficiency breathability effect. In addition, the waterproof and breathable membrane layer 12 can isolate external liquids such as water while allowing breathability, preventing liquids from entering the shoe and affecting wearing comfort. Based on this, to address the problem of water layers adhering to the waterproof and breathable part 121 blocking its breathability and affecting its breathability, this invention adds an elastic memory sheet as a vibration component 3. The elastic memory sheet switches between two states: downward deformation under foot pressure and upward restoration of its original shape when no foot pressure is applied. This drives the waterproof and breathable part 121 to reciprocate up and down, achieving vibration and shaking off the water layer adhering to the lower surface of the waterproof and breathable part 121. This prevents external water layers from blocking the waterproof and breathable part 121 and affecting breathability and moisture penetration into the shoe. Furthermore, there is a vibration space 13 between the waterproof and breathable part 121 and the mesh frame 1112, allowing the elastic memory sheet and the waterproof and breathable part 121 to swing downward or move during vibration, ensuring that the vibration of the elastic memory sheet and the waterproof and breathable part 121 is undisturbed. Specifically, the structure may also include an insole covering the waterproof and breathable membrane layer 12. Users can apply pressure to the elastic memory sheet by stepping on it, and the insole has cushioning properties to ensure comfort. The insole can be made of foamed resin material, and its lower surface can have a downward-protruding pressure-applying part facing the elastic memory film. This protruding pressure-applying part can apply targeted pressure to the deformable parts of the elastic memory film. The elastic memory film can be a highly elastic metal sheet or resin sheet. The waterproof and breathable membrane layer 12 is a high-polymer waterproof material, using TPU film or EPTFE (polytetrafluoroethylene), or at least one of the following: PP spunbond nonwoven fabric, PE polymer breathable membrane, or PP spunbond nonwoven fabric. The waterproof and breathable membrane should be highly breathable, heat-resistant, anti-aging, and have a hydrostatic pressure of over 2 meters. The manufacturing process should be a pure thermal composite technology, without glue, so it can withstand temperatures above 110 degrees Celsius, has high strength and anti-aging properties, and meets international standards such as those of Europe and America.

[0058] To ensure the water layer of the waterproof and breathable membrane 12 can be shaken off, and to ensure breathability and waterproofness, the specific structure can be as follows: the vibrating component 3 includes an annular memory elastic sheet surrounding the waterproof and breathable part 121. The center of the annular memory elastic sheet is an elastic sheet opening 31 corresponding to the waterproof and breathable part 121. The annular memory elastic sheet has an inner ring edge 32 in the inner ring and an outer ring edge 33 in the outer ring. The inner ring edge 32 is higher than the outer ring edge 33. The annular memory elastic sheet gradually slopes downward and outward from the inner ring edge 32 to the outer ring edge 33. The annular memory elastic sheet is connected to the waterproof and breathable membrane 12. The inner ring edge 32 surrounds the elastic sheet opening 31, which allows the waterproof and breathable part 121 to breathe. When the user lifts their foot or the annular memory elastic sheet is not under pressure, the inner edge 32 is above the outer edge 33, presenting an overall shape that is high in the middle and low around the edges, and the annular memory elastic sheet is in its stable original position. When the user applies pressure or the inner ring of the annular memory elastic sheet is subjected to force, the inner edge 32 quickly moves downward and suddenly stops below the outer edge 33, causing the waterproof and breathable part 121 to suddenly move downward and stop abruptly at the lowest point. The waterproof and breathable part 121 will vibrate due to inertia (especially under the additional gravity of the attached water layer, which can increase the inertia and vibration intensity), thus causing it to shake off. The effect of water droplets, water films, and other water layers adhering to the lower surface of the waterproof and breathable part 121: At this time, the annular memory elastic sheet is in an unstable position. When the user lifts their foot again or the pressure is removed, under the elastic memory effect of the annular memory elastic sheet, the inner edge 32 drives the waterproof and breathable part 121 to suddenly move upward to a high point and then suddenly stop. The waterproof and breathable part 121 will vibrate again due to inertia (especially under the additional gravity of the adhering water layer, the inertia and vibration intensity can be increased), so as to shake off the water layer adhering to the lower surface of the waterproof and breathable part 121 again. At this time, the annular memory elastic sheet returns to its stable original position. To simplify and specifically implement the function of the annular memory elastic sheet, the specific structure can be that the cross-section of the annular memory elastic sheet extends in a straight line from the outer edge 33 to the inner edge 32. To further ensure the elastic memory performance of the annular memory elastic sheet, another shape for the annular memory elastic sheet can be that its cross-section is concave and curved inward to form an arched curved portion 34. The arched curved portion 34 can further buffer, absorb, and rebound the force on the annular memory elastic sheet during deformation, and can also accumulate compressive energy for a more rapid release of elastic potential energy. This improves deformation sensitivity and enhances the vibration effect of the waterproof and breathable part 121, thereby ensuring the effectiveness of shaking off the water layer and the comfort of wearing and stepping on it. Furthermore, the outwardly and upwardly arched upper surface of the annular memory elastic sheet can make more favorable contact with the waterproof and breathable membrane layer 12. To further ensure the elastic memory performance of the annular memory elastic sheet, another shape for the annular memory elastic sheet can be that its cross-section is arched and curved outward at the top and concave and curved inward at the bottom to form an S-shaped curved portion 35.The S-shaped bend 35 can form a spring-like energy storage structure on the annular memory elastic sheet body, further buffering, absorbing, and rebounding the force on the annular memory elastic sheet during deformation. It can also accumulate compressive energy for more rapid elastic potential energy release, improving deformation sensitivity while enhancing the vibration effect of the waterproof and breathable part 121, thereby ensuring the effect of shaking off the water layer and the comfort of wearing and stepping on it. Furthermore, the upper part of the annular memory elastic sheet that arches outward and upward can make more friendly contact with the waterproof and breathable membrane layer 12, and the lower part of the annular memory elastic sheet that arches inward and downward can make more friendly contact with the base layer 11. To ensure the easy elastic deformation performance of the annular memory elastic sheet, the specific structure can be such that the angle of inclination of the line connecting the outer edge 33 to the inner edge 32 of the annular memory elastic sheet relative to the plane containing the outer edge 33, or the angle of inclination of the cross-section of the annular memory elastic sheet relative to the plane containing the outer edge 33, is 5-35°, preferably 10-30°. This allows the inner edge 32 of the annular memory elastic sheet to deform downwards or upwards with only a small resistance, ensuring that this resistance is less than the elastic force of the annular memory elastic sheet itself. This is especially important when the annular memory elastic sheet needs to rely on its own elastic force to move the inner edge 32 from downwards to return to its initial state; in this case, the resistance must be less than its own elastic force. The angle of inclination of the cross-section of the annular memory elastic sheet relative to the plane containing the outer edge 33 can specifically be 10, 15, 20, 25, or 30°. If the inclination angle of the cross-section of the annular memory elastic sheet relative to the plane containing the outer edge 33 is too large, the elastic force of the annular memory elastic sheet itself may not be able to overcome the resistance required to return to its original shape and thus cannot return to its initial state. Conversely, if the inclination angle of the cross-section of the annular memory elastic sheet relative to the plane containing the outer edge 33 is too small, it will reduce the energy of vibration, which may result in the inability to shake the water layer off the lower surface of the waterproof and breathable part 121. The shape of the annular memory elastic sheet can be circular, elliptical, rhomboid, square, triangular, trapezoidal, or more than one quadrilateral regular polygon. The annular memory elastic sheet can be a metal sheet or a resin sheet. The material of the annular memory elastic sheet can be a sheet structure of elastic materials such as steel sheets, memory alloy sheets, elastic resin sheets, or carbon fiber sheets, especially sheets of materials with high elastic memory, such as carbon steel sheets, manganese steel sheets, TPU sheets, PET sheets, or PC sheets. It can also be a composite sheet structure of two or more materials, such as a laminated composite of metal sheets and resin sheets. When the annular memory elastic sheet is made of metal, the sheet thickness is 0.2-0.5mm; when the annular memory elastic sheet is made of resin or carbon fiber, the sheet thickness is 0.3-0.9mm. If the material is too thick, it will not deform easily and will be difficult to drive the vibration of the waterproof and breathable part 121; if the material is too thin, the elasticity will be insufficient.

[0059] Furthermore, the outer edge 33 has two or more notches 36. These notches 36 can form a spring-like energy storage structure on the outer edge 33 of the annular memory elastic sheet body, further buffering, absorbing, and rebounding the force on the annular memory elastic sheet during deformation. They can also accumulate compressive energy for a more rapid release of elastic potential energy, improving deformation sensitivity while enhancing the vibration effect of the waterproof and breathable part 121, thereby ensuring the effectiveness of shaking off water and the comfort of wearing and walking on it. To further ensure the aforementioned effects, the specific structure can be such that three or more notches 36 are evenly arranged along the outer edge 33. This structure ensures the uniformity and balance of the elastic deformation of the outer edge 33 of the annular memory elastic sheet as a spring.

[0060] To achieve the connection and positioning between the waterproof and breathable membrane layer 12 and the annular memory elastic sheet, the waterproof and breathable membrane layer 12 further includes an annular connecting portion 122 that connects to the annular memory elastic sheet, with the annular connecting portion 122 surrounding the waterproof and breathable portion 121. After the annular memory elastic sheet and the waterproof and breathable membrane layer 12 are connected, the vibration of the annular memory elastic sheet will cause the waterproof and breathable portion 121 to vibrate synchronously. In particular, the annular connecting portion 122 surrounding the waterproof and breathable portion 121 ensures that the annular memory elastic sheet drives the inner ring of the waterproof and breathable portion 121 to move synchronously. Specifically, the annular memory elastic sheet and the annular connecting portion 122 are fixedly connected, and the waterproof and breathable portion 121 is stretched and tightened outward to form a waterproof and breathable tightening part. When the waterproof and breathable part 121 is fixed by the annular memory elastic sheet and stretched outward to form a waterproof and breathable tensioning part, the waterproof and breathable part 121 is less likely to absorb vibration force and energy by wrinkles or other non-vibrating curved surfaces. This allows it to more easily utilize its own elasticity and vibrate, ensuring that the waterproof and breathable part 121 has a higher vibration frequency that follows the annular memory elastic sheet, thus guaranteeing the effect of shaking off the water layer. Furthermore, the tensioned waterproof and breathable part 121 will not hide the water layer due to wrinkles, preventing the water layer from being difficult to shake off. Specifically, the annular memory elastic sheet can be connected to the lower or upper surface of the waterproof and breathable membrane layer 12, preferably the lower surface. To achieve a specific connection between the annular memory elastic sheet and the waterproof and breathable membrane layer 12, the annular memory elastic sheet and the annular connecting part 122 are connected together by adhesive, ensuring a firm bond and preventing the adhesive layer from covering the waterproof and breathable part 121.

[0061] To achieve the positioning and support of the substrate layer 11 and the annular memory elastic sheet, the substrate layer 11 further includes an elastic sheet limiting groove 112 for limiting the position of the annular memory elastic sheet. The elastic sheet limiting groove 112 is arranged around the vent hole 111 of the substrate. This structure allows the annular memory elastic sheet to be accommodated and limited within the elastic sheet limiting groove 112, ensuring that the elastic sheet opening 31 and the waterproof and breathable part 121 of the annular memory elastic sheet correspond to the vent hole 111 of the substrate. This ensures precise connection of the breathable channel while also allowing the annular memory elastic sheet to deform within the elastic sheet limiting groove 112 and to vibrate the waterproof and breathable part 121. This ensures precise, stable, and durable vibration, preventing displacement or misalignment that could interfere with or cause the annular memory elastic sheet to malfunction. To facilitate smooth deformation of the annular memory elastic sheet within the elastic sheet limiting groove 112, the specific structure can be such that the elastic sheet limiting groove 112 has an inner groove ring 1121 near the substrate vent hole 111 and an outer groove ring 1122 away from the substrate vent hole 111. The inner edge 32 of the annular memory elastic sheet protrudes further inward than the inner groove ring 1121, and the inner groove ring 1121 is higher than the grid frame 1112. This structure allows the inner edge 32 of the annular memory elastic sheet to deform downward toward the substrate vent hole 111 without being interfered with by the inner groove ring 1121. The inner groove ring 1121 can also serve as a lever support point for the downward deformation of the inner edge 32, making the annular memory elastic sheet easier to deform. Furthermore, the inner groove ring 1121 being higher than the grid frame 1112 provides sufficient space between the inner groove ring 1121 and the grid frame 1112 for the inner edge 32 to deform downward. To facilitate downward deformation of the inner edge 32 of the annular memory elastic sheet by applying pressure, the structure can be such that the height of the annular memory elastic sheet is greater than the depth of the elastic sheet limiting groove 112, and the upper end of the annular memory elastic sheet protrudes beyond the upper opening of the elastic sheet limiting groove 112, making the inner edge 32 more easily subjected to pressure such as stepping pressure. To facilitate the adaptation of the outer ring of the waterproof and breathable membrane layer 12 to the deformation of the annular memory elastic sheet, the structure can be such that the waterproof and breathable membrane layer 12 has a bending buffer 123 that bends downward and sinks into the elastic sheet limiting groove 112. The bending buffer 123 is arranged around the annular memory elastic sheet. This structure allows the outer ring of the waterproof and breathable membrane layer 12 to adapt to the deformation of the annular memory elastic sheet, preventing the waterproof and breathable membrane layer 12 from being pulled, deformed, displaced, or even torn.

[0062] Furthermore, the waterproof and breathable membrane layer 12 also includes a connection area 124 connected to the substrate layer 11, with the connection area 124 surrounding the bending buffer zone 123. This structure enables the waterproof and breathable membrane layer 12 to be fixedly connected to the substrate layer 11, and can even achieve a composite connection effect. The connection area 124 surrounding the bending buffer zone 123 ensures that the connection area between the waterproof and breathable membrane layer 12 and the substrate layer 11 does not interfere with the movement of the bending buffer zone 123 and the annular memory elastic sheet. Specifically, the connection area 124 can be bonded to the upper surface of the substrate layer 11 by adhesive bonding or hot pressing. The substrate layer 11 has multiple substrate breathable holes 111. The entire waterproof and breathable membrane layer 12 is covered on the upper surface of the substrate layer 11. The waterproof and breathable membrane layer 12 has multiple waterproof and breathable parts 121, which are located above the substrate breathable holes 111. The connecting area 124 separates the adjacent waterproof and breathable parts 121. The multiple substrate breathable holes 111, together with the multiple waterproof and breathable parts 121 and the multiple annular memory elastic sheets, can form multiple breathable breathing units, which can ensure that the breathable breathing pad and the sole of the shoe have a more comprehensive breathable breathing effect.

[0063] A breathable, breathing sole, such as Figure 1-18As shown, the invention also includes a sole body 2 for mounting a breathable pad for the sole. The sole body 2 has a sole through-hole 21 corresponding to the breathable through-hole 111 of the substrate. In actual installation and use, the invention can be connected to the upper to form a complete shoe. The waterproof and breathable part 121 and the breathable through-hole 111 of the substrate correspond to the sole through-hole 21. The three can connect the inside of the shoe with the outside air to form a smooth breathable channel inside the shoe during wear, ensuring a high-efficiency breathability. In addition, the waterproof and breathable membrane layer 12 can isolate external liquids such as water while allowing breathability, preventing liquids from entering the shoe and affecting wearing comfort. Based on this, to address the problem of water layers adhering to the waterproof and breathable part 121 blocking its breathability and thus affecting ventilation, this invention adds an elastic memory sheet as a vibration component 3. The elastic memory sheet switches between two states: downward deformation under pressure and upward restoration of its original shape when no pressure is applied. This drives the waterproof and breathable part 121 to reciprocate up and down, achieving vibration and shaking off the water layer adhering to the lower surface of the waterproof and breathable part 121. This prevents external water layers from blocking the waterproof and breathable part 121 and affecting breathability and moisture penetration into the shoe. Specifically, the structure may also include an insole covering the waterproof and breathable membrane layer 12. Users can apply pressure to the elastic memory sheet by stepping on it. The insole has cushioning properties to ensure comfort. The insole may be made of foamed resin material, and its lower surface may have a downward protruding pressure-applying part facing the elastic memory sheet. This protruding pressure-applying part can apply targeted pressure to the deformed parts of the elastic memory sheet. The specific structure can be as follows: multiple sole through holes 21 are formed on the sole body 2, corresponding one-to-one with multiple substrate ventilation through holes 111; the substrate layer 11 is fixed to the upper surface of the sole body 2, and the upper surface of the sole body 2 has a positioning groove 22 for accommodating and positioning the substrate layer 11. The sole body 2 precisely positions and fixes the substrate layer 11 through the positioning groove 22. The multiple sole through holes 21, together with the multiple substrate ventilation through holes 111, multiple waterproof and breathable parts 121, and multiple annular memory elastic sheets, can constitute multiple breathable breathing units, ensuring that the breathable breathing pad and sole of the sole have a more comprehensive breathable breathing effect. Specifically, the substrate ventilation through hole 111 has a downwardly protruding substrate protrusion 113, which extends downward into the sole through hole 21. Multiple substrate protrusions 113 can correspond to and cooperate with multiple sole through holes 21, enabling precise and stable positioning and locking of the substrate layer 11 and the sole body 2 from multiple directions, ensuring installation accuracy and stability during use. A further specific structure may be provided where the substrate protrusions 113 have a tapered slope that gradually decreases in size from the root to the tip, facilitating the insertion of the substrate protrusions 113 into the sole through holes 21.The sole body 2 may specifically include a foamed elastic midsole on top and a wear-resistant outsole composited on the lower surface of the foamed elastic midsole. The wear-resistant outsole may be made of rubber or TPU material. The positioning groove 22 is formed on the upper surface of the foamed elastic midsole. The substrate layer 11 may be connected and fixed together with the positioning groove 22 by adhesive bonding.

[0064] The product form of the present invention is not limited to the illustrations and embodiments shown in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of the present invention.
