Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to a breathable shoe upper component and a finished shoe. Background Technology
[0002] As consumers increasingly demand greater comfort in footwear, breathability has become a core indicator in footwear design. Especially during prolonged walking or exercise, the heel area inside the shoe easily accumulates sweat, creating a hot and humid environment that leads to stuffy, slippery feet and even odor and bacterial growth, severely impacting the wearing experience. Currently, the industry has developed various technical solutions for breathability design of shoe uppers and heel counters. These solutions utilize woven fabrics or mesh materials such as cotton and polyester to create the uppers and heel counters, relying on the fiber pores of the fabric or the mesh openings to achieve gas exchange between the inside and outside of the shoe. However, this type of solution relies entirely on passive diffusion due to the natural concentration and temperature differences between the inside and outside of the shoe, resulting in extremely low breathability efficiency, far lower than the rate of sweating in the heel area during walking. Furthermore, during walking, the pressure of the heel on the heel counter causes the fabric pores and mesh openings to deform and close, actually blocking the breathability channels. Some solutions use double-layer fabric composites or attach support plates, such as TPU plates, inside the fabric. However, the pores of double-layer fabrics are prone to misalignment, creating dead zones for ventilation. The area covered by the support plate has no ventilation channels at all, causing the heel counter to become a localized area of heat and moisture accumulation, especially the heel apex area. If only a single layer of highly breathable fabric is used, the heel counter will easily deform due to insufficient support, affecting foot stability.
[0003] Therefore, existing solutions are all static breathable designs, which do not utilize the dynamic compression and release action of the heel against the back of the shoe during walking to create an active exhaust circulation. They cannot achieve efficient gas exchange through compression exhaust and repositioning intake, and the breathability is far from meeting actual needs. Utility Model Content
[0004] The purpose of this utility model is to provide a breathable shoe upper component and a finished shoe to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] This utility model provides a breathable shoe upper component, including:
[0007] The upper and bottom edge are bonded to the sole;
[0008] The heel counter has its front edge bonded to the upper and its bottom edge bonded to the sole, forming an inner cavity with the upper and sole. The heel counter includes an outer support layer and an inner lining.
[0009] The flexible corrugated airbag, which is elongated, is sealed and fitted between the support layer and the guide layer, and is vertically arranged on both sides of the heel counter. The air outlet of the flexible corrugated airbag is connected to the outside through a one-way valve, and the air inlet of the flexible corrugated airbag is connected to the inner cavity of the shoe through the guide layer. This allows the gas in the flexible corrugated airbag to be discharged through the one-way valve when walking and to be drawn into the inner cavity of the shoe when the deformation recovers.
[0010] This technical solution addresses the limitation of existing static ventilation systems in achieving active air exhaust through walking dynamics. It utilizes the dynamic compression and release mechanical properties of the heel against the shoe's heel counter during walking to drive the flexible corrugated airbag to compress and reposition itself. Combined with the one-way valve's unidirectional conduction function, it constructs an active air exhaust system from the shoe's internal humid and hot gas to the guiding layer, the flexible corrugated airbag, the one-way valve, and the outside environment. Simultaneously, it uses the negative pressure inside the shoe to replenish dry air from the existing ventilation structure on the upper, achieving efficient gas renewal within the shoe.
[0011] As an extension of the above solution: the one-way valve is a duckbill valve, which is located at the highest point of the heel counter, below the heel pull tab, or near the collar. The opening pressure of the duckbill valve is extremely low; the opening pressure of a miniature duckbill valve can be less than 0.001 MPa. Once the pressure is reached, the lip opens instantly. Compared to existing one-way valves, the duckbill valve opens almost instantly upon pressure generation, resulting in an extremely fast response.
[0012] As an extension of the above solution: a ventilation channel is provided at the top of the heel counter, extending laterally to the flexible corrugated airbags on both sides. The air outlets of the flexible corrugated airbags are connected to the ventilation channel, which is connected to the outside via a one-way valve. In this extended solution, the exhaust from the flexible corrugated airbags on both sides converges and is discharged through the same ventilation channel. The airflow path changes from dual-path dispersed exhaust to single-path concentrated exhaust, requiring only one one-way valve to achieve exhaust, thus simplifying the assembly process.
[0013] As an extension of the above solution: the flexible corrugated airbag is provided in several parts, and the flexible corrugated airbags located on the same side are equidistantly distributed in the lateral direction. The air outlet is located at the top of the flexible corrugated airbag, and the air inlet is located at the bottom or lower part of the flexible corrugated airbag.
[0014] This extended design ensures that when the heel counter is compressed by the foot, pressure is distributed evenly to each flexible corrugated air bladder, maintaining ventilation even if a single bladder fails due to extreme conditions. The air vents are located at the top, utilizing the natural principle of rising hot air to help expel the hottest and humidest gases; the air inlets are located at the bottom or lower part, more effectively drawing in the cool, humid air that accumulates in the lower heel area.
[0015] As an extension of the above solution: the flexible corrugated airbag is made of a flexible TPU film with alternating wavy textures on its surface. The wavy textures provide a preset, low-resistance deformation path for the airbag's compression and rebound, ensuring that it can work reliably in the set manner each time and avoiding fatigue rupture caused by irregular twisting.
[0016] As an extension of the above solution, the surface of the flexible corrugated airbag is provided with raised strip-shaped or network-shaped reinforcing ribs. The reinforcing ribs effectively limit the excessive expansion and bulging of the flexible corrugated airbag during use or when heated, maintaining structural stability.
[0017] As an extension of the above solution: the airflow guiding layer is made of a three-dimensional horizontally woven spaced fabric, forming a three-dimensional channel from the shoe cavity to the heel counter. The air inlet of the flexible corrugated airbag is an open opening, set close to the airflow guiding layer. This three-dimensional channel provides a continuous and stable airflow path, ensuring that moisture can be efficiently delivered to the air inlet of the flexible corrugated airbag.
[0018] As an extension of the above solution: the guiding layer includes an inner hydrophilic layer near the shoe's inner cavity and an outer hydrophobic layer adjacent to the flexible corrugated airbag. The inner hydrophilic layer and the outer hydrophobic layer form a directional moisture-wicking channel. The hydrophilic and hydrophobic layers can be achieved by applying different chemical treatments to both sides of the guiding layer fabric, such as hydrophilic finishing and hydrophobic finishing. The hydrophilic layer quickly absorbs sweat and pumps the moisture to the hydrophobic layer through the capillary effect of the material. The hydrophobic layer prevents moisture backflow and allows water vapor to pass through, realizing unidirectional transmission of liquid water from the inside to the outside.
[0019] As an extension of the above solution: the air inlet of the flexible corrugated airbag is connected to or embedded in the outer hydrophobic layer. The air inlet can be connected to the outer hydrophobic layer by sewing, high-frequency welding, or adhesive bonding. Alternatively, an opening can be provided at a corresponding position in the flow guide layer, with the edge of the air inlet sealingly connected to this opening, and the airbag body partially embedded in the three-dimensional structure of the flow guide layer. This physical connection or embedding ensures unobstructed airflow from the flow guide layer to the airbag.
[0020] On the other hand, this utility model also provides a finished shoe, including a breathable shoe upper component as described above.
[0021] This invention solves the problem that existing static ventilation cannot achieve active air exhaust through walking dynamics. It utilizes the dynamic compression and release mechanical properties of the heel against the heel counter during walking to drive the flexible corrugated airbag to compress and reset deformation. Combined with the one-way valve's one-way conduction function, it constructs an active air exhaust system from the shoe's internal humid and hot gas to the guiding layer, the flexible corrugated airbag, the one-way valve, and the outside. At the same time, it uses the negative pressure inside the shoe to replenish dry air from the existing ventilation structure of the shoe surface, achieving efficient gas renewal inside the shoe.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] Reference Figures 1 to 3 The following are several embodiments of a breathable shoe upper component and a finished shoe according to the present invention.
[0032] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a breathable shoe upper component, comprising:
[0033] The upper 100 is bonded to the sole 200 at the bottom edge; the upper 100 is a sheet-like structure covering the front and middle of the foot, and is one of the main contact parts between the upper component and the foot. It uses existing conventional breathable fabrics, such as mesh or knitted fabric.
[0034] The heel counter 300 has its front edge bonded to the upper 100 and its bottom edge bonded to the sole 200, forming an inner cavity with the upper 100 and sole 200. The heel counter 300 includes an outer support layer 310 and an inner lining drainage layer 320. The heel counter 300 is a three-dimensional structure covering the heel and the back of the ankle. The support layer 310 provides structural support for the heel counter, preventing it from collapsing or deforming during walking and ensuring foot stability.
[0035] The flexible corrugated airbag 400 is elongated and sealed between the support layer 310 and the guide layer 320, and is vertically arranged on both sides of the heel counter 300. The air outlet 410 of the flexible corrugated airbag 400 is connected to the outside through a one-way valve 500, and the air inlet of the flexible corrugated airbag 400 is connected to the inner cavity of the shoe through the guide layer 320. This allows the gas in the flexible corrugated airbag 400 to be discharged through the one-way valve 500 when walking and squeezed, and to be drawn in from the inner cavity of the shoe when the deformation recovers.
[0036] In this embodiment, the guiding layer directs hot and humid gas inside the shoe into the flexible corrugated airbag, while also providing skin-friendly and moisture-wicking functions to reduce sweat buildup on the heel. The flexible corrugated airbag is a long strip-shaped airbag made of TPU film using mature blow molding or hot pressing technology. It is located between the support layer and the guiding layer, resembling a flexible rib, and is vertically or with a certain curvature attached to both sides of the heel counter. This maximizes the overlap of the pressure surfaces of the heel against the heel counter, providing maximum airflow. During walking, the compression and release of the heel against the heel counter causes the flexible corrugated airbag to undergo significant and visible compression and rebound, thereby generating a pumping effect.
[0037] In this embodiment, the expelled gas is the original humid and warm air inside the shoe. Subsequently, due to negative pressure, filtered dry air is naturally replenished from the existing breathable areas with waterproof and breathable membranes, such as the tongue and upper, creating a circulation throughout the shoe's interior. Specifically, during foot compression (exhaust): when the heel strikes the ground, it compresses the heel counter, flattening the air bladder and increasing internal pressure. This expels the gas sealed within the flexible corrugated air bladder through a one-way valve. During foot lift and rebound (inhalation): when the heel lifts, the compression is released, and the flexible corrugated air bladder returns to its original shape due to the elasticity of its corrugated structure, generating negative pressure. This draws in the humid and warm air from the heel area through the guide layer, preparing for the next compression and exhaust. Throughout the entire process, the flexible corrugated air bladder only exchanges gas with the shoe's interior.
[0038] Those skilled in the art will understand that the flexible corrugated airbag is made of highly resilient and fatigue-resistant TPU material. The corrugated structure, also known as the pleated design, is similar to the bellows of an accordion or the pleated part of a straw. It inherently has an elastic tendency to stubbornly return to its original shape after being compressed. The corrugations or pleats provide a clear, low-resistance bending axis, ensuring that the flexible corrugated airbag can only be flattened uniformly and predictably along the direction defined by the corrugations or pleats when compressed, rather than twisting, bulging, or collapsing unpredictably like a smooth airbag.
[0039] To further explain, when a person is standing still, their weight is primarily transferred through the foot bones to the sole of the shoe, and then distributed across the entire ground. At this time, the heel is in contact with the inside of the shoe's heel counter, but the pressure between them is mainly vertical, with very little lateral compression on the sides of the shoe's heel counter. Therefore, in this state, the flexible corrugated air bladder experiences very little pressure and remains essentially in its natural state, neither releasing nor inhaling air. When walking, as the heel lifts and the ankle bends, the heel separates from the shoe's heel counter. At this time, the flexible corrugated air bladder is unpressurized and in its reset state. When the heel lands and during the subsequent push-off, the force exerted by the foot on the entire shoe is multidirectional and intense. This action causes a momentary, significant lateral compression of the heel muscles and bones against the shoe's heel counter, especially during turning or tiptoeing. The flexible corrugated air bladder is designed to respond to this momentary, significant lateral compression. Its corrugated structure reduces its lateral compressive stiffness, making it easily compressible and thus releasing air. Once the momentary lateral compressive force disappears, the stored elastic potential energy is immediately released, pushing the flexible corrugated airbag back to its original shape, thus generating negative pressure and drawing air from the shoe's inner cavity. When the flexible corrugated airbag is compressed and deflated, its internal pressure is temporarily lower than the air pressure inside the shoe's inner cavity. When the compressive force is released, the material's elastic recovery force plays a major role, while the slight pressure difference between the inside and outside of the shoe's inner cavity also helps the flexible corrugated airbag return to its original shape more quickly, ensuring a more reliable reset process.
[0040] This embodiment addresses the limitation of existing static ventilation systems in achieving active airflow during walking. It utilizes the dynamic compression and release of the heel against the shoe's heel counter during walking to drive the flexible corrugated airbag to compress and reposition itself. Combined with the one-way valve's unidirectional flow function, it constructs an active airflow system from the shoe's internal humid and hot gas layer through the flexible corrugated airbag, the one-way valve, and the outside environment. Simultaneously, the negative pressure within the shoe cavity replenishes dry air from the existing ventilation structure on the upper, achieving efficient gas renewal within the shoe. Compared to traditional technologies where ventilation, support, and moisture-wicking structures are independent or even interfering, this embodiment employs a layered design. The support layer provides structural strength, the flow layer directs airflow and moisture, and the flexible corrugated airbag is embedded between the two layers. This design does not affect the function of the support layer and combines ventilation and moisture wicking through the flow layer, forming a synergistic system of stable support, moisture guidance, and dynamic airflow. Humid and hot gas from the heel apex area can quickly enter the flexible corrugated airbag through the channels of the flow layer for expulsion to the outside environment.
[0041] In an optional embodiment, such as Figure 1 and Figure 3 As shown, the one-way valve 500 is a duckbill valve, located at the highest point of the heel counter 300, below the heel pull tab, or near the collar. The duckbill valve is made of medical-grade silicone. The main body of the duckbill valve has an integrated structure of a flat tube and a duckbill. The air inlet, which connects to the flexible corrugated air bladder, is a cylindrical flat tube, and the air outlet is a duckbill-shaped opening. The opening pressure of the duckbill valve in this embodiment is extremely low; the opening pressure of the miniature duckbill valve can be below 0.001 MPa. Once the pressure is reached, the lip opens instantly. Compared to existing one-way valves, the duckbill valve opens almost instantly upon pressure generation, resulting in an extremely fast response.
[0042] It should be noted that, because the duckbill valve provides a path with extremely low flow resistance, most of the gas generated by squeezing the flexible corrugated airbag will be discharged from the outlet and the one-way valve. The guide layer on the air inlet side of the flexible corrugated airbag is porous as a whole. The gas needs to pass through the three-dimensional network structure of the guide layer material that may be compressed in the opposite direction. The path is long and tortuous. A small amount of gas may seep into the guide layer, but its impact is negligible and will not affect the overall exhaust operation.
[0043] In an optional embodiment, such as Figure 3 As shown, the top of the heel counter 300 of the shoe is provided with a ventilation channel 330, which extends laterally to the flexible corrugated airbags 400 on both sides. The air outlet 410 of the flexible corrugated airbags 400 is connected to the ventilation channel 330, and the ventilation channel 330 is connected to the outside through a one-way valve 500.
[0044] In this embodiment, the ventilation channel is a horizontal hollow channel integrated into the top of the heel counter, extending laterally 1-2mm below the heel collar to both sides of the heel counter, covering the air outlet areas of the flexible corrugated airbags on both sides. A connecting hole is provided at the bottom of the ventilation channel corresponding to the air outlets of the flexible corrugated airbags on both sides. In this embodiment, only one one-way valve or duckbill valve is needed, positioned at the longitudinal centerline of the heel counter to form an airflow convergence point, avoiding uneven airflow caused by offset. The flexible corrugated airbags on both sides are simultaneously compressed, and gas enters the ventilation channel through their respective air outlets. The airflow flows laterally towards the convergence point within the ventilation channel, and the converged gas quickly pushes open the duckbill valves to expel it to the outside. The flexible corrugated airbags on both sides rebound synchronously, generating negative pressure. Due to the elasticity of the silicone, the duckbill valves close quickly, and the humid and hot gas inside the shoe cavity enters the flexible corrugated airbags on both sides through the guide layer.
[0045] In this embodiment, the exhaust gas from the flexible corrugated airbags on both sides converges and is discharged through the same vent. The airflow path changes from dual-path dispersed exhaust to single-path centralized exhaust, requiring only one one-way valve to achieve exhaust, thus simplifying the assembly process.
[0046] In an optional embodiment, such as Figure 1 and 3 As shown, there are several flexible corrugated airbags 400. The flexible corrugated airbags 400 located on the same side are equidistantly distributed in the lateral direction. The air outlet 410 is located at the top of the flexible corrugated airbag 400, and the air inlet (not shown in the figure) is located at the bottom or lower part of the flexible corrugated airbag 400.
[0047] This design ensures that when the heel counter is compressed by the foot, pressure is distributed evenly across the individual flexible corrugated air bladders, maintaining ventilation even if a single bladder fails due to extreme conditions. The air vents are located at the top, utilizing the natural principle of rising hot air to expel the hottest and humidest gases; the air inlets are located at the bottom or lower part, more effectively drawing in the cool, humid air that accumulates in the lower heel area.
[0048] In an optional embodiment, the flexible corrugated airbag is made of a flexible TPU film with alternating wavy textures on its surface. This flexible corrugated airbag with wavy textures can be manufactured using mature blow molding or hot pressing processes, such as bonding two or more film materials together in a mold by heating and pressurizing. The wavy texture provides a preset, low-resistance deformation path for the airbag's compression and rebound, ensuring it works reliably in the set manner each time and avoiding fatigue breakage caused by irregular twisting.
[0049] In an optional embodiment, the surface of the flexible corrugated airbag is provided with raised strip-shaped or network-shaped reinforcing ribs. These ribs effectively limit excessive expansion and bulging of the flexible corrugated airbag during use or when heated, maintaining structural stability. The ribs can also distribute localized stress over a larger area, greatly reducing material fatigue, preventing cracks from forming at stress concentration points such as the roots of wrinkles, and improving durability.
[0050] In an optional embodiment, the airflow guiding layer is made of a three-dimensional horizontally woven spacer fabric, forming a three-dimensional channel from the shoe's inner cavity to the heel counter. The air inlet of the flexible corrugated airbag is an open opening, positioned close to the airflow guiding layer. The three-dimensional horizontally woven spacer fabric consists of a surface layer, a bottom layer, and hollow fiber bundles connecting the two layers, forming a stable three-dimensional hollow structure that creates a three-dimensional channel from the shoe's inner cavity to the heel counter. This three-dimensional channel provides a continuous and stable airflow path, ensuring that moisture can be efficiently delivered to the air inlet of the flexible corrugated airbag. Furthermore, since the air inlet of the flexible corrugated airbag is close to the airflow guiding layer, no complex pipe connections are required; airflow connection can be achieved through material lamination, making the manufacturing process simple and reliable.
[0051] In an optional embodiment, the flow-guiding layer includes an inner hydrophilic layer near the shoe cavity and an outer hydrophobic layer adjacent to the flexible corrugated airbag, the inner hydrophilic layer and the outer hydrophobic layer forming a directional moisture-guiding channel.
[0052] In this embodiment, the hydrophilic layer and the hydrophobic layer can be achieved by applying different chemical treatments to both sides of the flow-guiding layer fabric, such as hydrophilic treatment and hydrophobic treatment. The hydrophilic layer quickly absorbs sweat and pumps the moisture to the hydrophobic layer through the capillary effect of the material. The hydrophobic layer prevents moisture from flowing back and allows water vapor to pass through, thus realizing the one-way transmission of liquid water from the inside to the outside.
[0053] In an optional embodiment, the air inlet of the flexible corrugated airbag is connected to or embedded in the outer hydrophobic layer. The air inlet can be connected to the outer hydrophobic layer by sewing, high-frequency welding, or adhesive bonding. Alternatively, an opening can be provided at a corresponding position in the flow-guiding layer, with the edge of the air inlet sealingly connected to this opening, and the airbag body partially embedded in the three-dimensional structure of the flow-guiding layer. This physical connection or embedding ensures unobstructed airflow from the flow-guiding layer to the airbag.
[0054] On the other hand, this utility model also provides a finished shoe, including a breathable shoe upper component as described above.
[0055] This embodiment addresses the limitation of existing static ventilation systems in achieving active air exhaust through walking dynamics. It utilizes the dynamic compression and release mechanical properties of the heel against the shoe's heel counter during walking to drive the flexible corrugated airbag to compress and reposition itself. Combined with the one-way valve's unidirectional conduction function, it constructs an active air exhaust system from the shoe's internal humid and hot gas to the guiding layer, the flexible corrugated airbag, the one-way valve, and the outside environment.
