Description

Technical Field

[0001] This utility model belongs to the field of footwear technology, and more specifically, relates to a children's shoe. Background Technology

[0002] In existing children's footwear products, especially some leather shoes that emphasize aesthetics, the shoe body often uses a single-layer material or thin structure design to reduce weight and cost. However, due to the thin overall material and lack of cushioning, this design reveals the following significant defects in actual use: 1. Uneven distribution of foot pressure: Insufficient cushioning performance in the sole and upper area leads to the inability to effectively distribute the ground reaction force during walking. The heel area is prone to wear and tear due to long-term concentrated pressure, and may even cause health problems such as plantar fasciitis; while the toe area, due to narrow space or excessively rigid material, will continuously compress the toes during the gait cycle (especially the push-off phase), causing pain, swelling, or deformation (such as hallux valgus); 2. Inability to adapt to different foot shapes and gait differences, exacerbating friction between the foot and the inner wall of the shoe, further reducing comfort. In summary, existing children's shoes are made of thin materials, lack cushioning, easily cause heel wear during walking, and compress the toes, resulting in poor comfort. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a children's shoe to solve the technical problem of poor comfort in existing children's shoes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a children's shoe is provided, including a sole, an upper disposed at the edge of the sole, and an insole disposed on the surface of the sole. The insole is provided with a raised arch cushioning part, the inner side of the upper and near the toe is provided with a toe cushioning part, and the inner side of the upper and near the heel is provided with a first heel cushioning part.

[0005] In the above design, the insole has an arch cushioning section to cushion and support the arch of the foot, the toe cushioning section at the toe of the shoe upper, and a first heel cushioning section at the heel of the shoe upper. This allows the toes to be wrapped and cushioned to a certain extent during walking, and the first heel cushioning section to wrap and cushion the heel, thereby improving the comfort of children's shoes.

[0006] In one possible implementation, the length of the insole is positively correlated with the thickness of the arch cushioning portion.

[0007] In one possible implementation, the ratio of the length of the insole to the thickness of the arch cushioning portion ranges from 17 to 26.

[0008] In one possible implementation, the thickness of the arch cushioning portion ranges from 6.8 mm to 10 mm.

[0009] In one possible implementation, the arch cushioning portion is 7.1 mm thick, and the insole is 13 cm long, suitable for children weighing 9 kg to 11 kg; or, the arch cushioning portion is 7.3 mm thick, and the insole is 13 cm long, suitable for children weighing 11 kg to 14 kg; or, the arch cushioning portion is 7.7 mm thick, and the insole is 17 cm long, suitable for children weighing 14 kg to 18 kg; or, the arch cushioning portion is 8.1 mm thick... The insole is 19cm long and suitable for children weighing 18kg to 23kg; or the arch cushioning is 8.5mm thick and the insole is 21cm long, suitable for children weighing 22kg to 30kg; or the arch cushioning is 8.9mm thick and the insole is 22cm long, suitable for children weighing 27kg to 38kg; or the arch cushioning is 9.3mm thick and the insole is 23cm long, suitable for children weighing 32kg to 49kg.

[0010] In one possible implementation, the density of the arch cushioning portion is in the range of 42 kg / m³. 3 Up to 60kg / m 3 The hardness range of the arch cushioning part is 10HD to 30HD.

[0011] In one possible implementation, the density of the arch cushioning portion is in the range of 60T, and the hardness of the arch cushioning portion is in the range of 20HD.

[0012] In one possible implementation, the user's weight is positively correlated with the thickness of the arch cushioning.

[0013] In one possible implementation, when the user's weight ranges from 10kg to 30kg, the thickness of the arch cushioning part ranges from 6.8mm to 8.8mm, and the thickness of the arch cushioning part increases by 1mm for every 1kg to 2kg increase in user weight; when the user's weight is 30kg or above, the thickness of the arch cushioning part is greater than 8.8mm, and the thickness of the arch cushioning part increases by 1mm for every 2kg to 3kg increase in user weight.

[0014] In one possible implementation, the thickness of the first heel cushioning portion on the side closer to the sole is less than the thickness of the first heel cushioning portion on the side farther from the sole.

[0015] In the above solution, the thickness of the first heel cushioning part near the sole is set to be less than the thickness of the first heel cushioning part away from the sole. The protruding part of the heel is matched with the thinner side, and the part of the heel near the ankle is matched with the thicker side, which conforms to the structural characteristics of the human heel.

[0016] In one possible implementation, the edge of the first heel cushioning portion near the sole is curved.

[0017] In the above solution, by setting the edge of the first heel cushioning part near the sole to be curved, the first heel cushioning part fits the ankle better, increases the wrapping effect, and improves the comfort of the ankle.

[0018] In one possible implementation, the insole includes a cushioning layer with resilience and a fabric layer covering the surface of the cushioning layer, wherein the cushioning layer has a raised arch cushioning portion at the arch position.

[0019] In the above design, the addition of a fabric layer enhances the insole's skin-friendliness, wicks away moisture, keeps feet dry, and reduces bacterial growth. Furthermore, the raised arch support effectively supports the arch of the foot, promoting healthy arch development in children and making walking more stable.

[0020] In one possible implementation, the fabric layer is made of Lycra material and the cushioning layer is made of foam; or, the fabric layer is made of mesh material and the cushioning layer is made of latex; or, the fabric layer is made of microfiber fleece material and the cushioning layer is made of memory foam; or, the fabric layer is made of knitted fabric and the cushioning layer is made of EVA.

[0021] In one possible implementation, the buffer layer has a raised second heel buffer portion at the heel position.

[0022] In the above solution, by setting a second heel cushioning part at the heel position of the cushioning layer, the impact force generated by the heel landing during walking and running can be effectively absorbed, reducing impact damage to the plantar fascia, ankle joint and knee; at the same time, through the appropriate density design, it conforms to the heel contour to provide stable support, prevent excessive inward or outward pronation of the foot, maintain gait balance, and distribute the pressure point of the heel to avoid local wear or fatigue accumulation, thereby improving the comfort and foot protection of long-term walking.

[0023] In one possible implementation, the density of the second heel cushioning portion is between the density of the cushioning layer and the density of the arch cushioning portion.

[0024] In the above solution, the density of the second heel cushioning part is between that of the cushioning layer and the arch cushioning part, which can balance resilience and durability.

[0025] In one possible implementation, the thickness of the buffer layer is 4 mm ± 0.5 mm.

[0026] In one possible implementation, the density of the buffer layer is 80 kg / cm³. 3 ±10kg / cm 3 .

[0027] In the above scheme, to balance cushioning capacity and comfort, the thickness of the cushioning layer can be 4mm ± 0.5mm, and the density of the cushioning layer can be set to 80kg / cm³. 3 ±10kg / cm 3 .

[0028] In one possible implementation, the outer edge of the arch cushioning portion coincides with the edge of the insole, and the inner edge of the arch cushioning portion includes a plurality of sequentially connected arc-shaped segments, with a recessed structure formed at the connection between two adjacent arc-shaped segments.

[0029] In the above solution, by setting the inner edge of the arch cushioning part as multiple sequentially connected arc segments, a concave structure is formed between two adjacent arc segments. This not only increases the contact area between the arch cushioning part and the arch of the foot, reduces the pressure on the arch cushioning part during exercise, and reduces the deformation of the arch cushioning part under pressure, but also shortens the rebound time of the arch cushioning part and improves the comfort of the insole.

[0030] In one possible implementation, the sole has a heel near the heel, and the height of the heel is positively correlated with the thickness of the toe cushioning portion.

[0031] In the above design, the higher the heel, the greater the pressure on the toes, and the thicker the toe cushioning should be to provide better support and protection for the toes. Conversely, the lower the heel, the greater the pressure on the toes, and the thinner the toe cushioning should be, while also providing more space for toe movement between the upper and the sole.

[0032] In one possible implementation, the inner side of the upper has a lining layer, and the toe cushioning portion is located between the upper and the lining layer.

[0033] In the above solution, the inner lining has moisture-wicking and perspiration-absorbing functions, and can also fix the toe cushioning part.

[0034] In one possible implementation, the toe cushion is cloud-shaped. Attached Figure Description

[0042] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] In existing children's footwear products, especially some leather shoes that emphasize aesthetic design, the shoe body often uses a single-layer material or a thin structure to reduce weight and cost. However, due to the thin overall material and lack of cushioning, such designs are prone to causing heel abrasions and squeezing the toes during actual use, resulting in poor comfort. Especially in children's shoes with a certain heel height (high heels), children's toes are constantly squeezed while standing and walking, easily leading to blisters and, with prolonged wear, toe deformities.

[0047] To alleviate or solve the above technical problems, this utility model proposes a new children's shoe, including a sole 10, an upper 20, and an insole 30. The inner side of the upper 20 near the toe is provided with a toe cushioning part 21, which is used to wrap the toes and cushion the impact on the toes, making the children's toes more comfortable. The inner side of the upper 20 near the heel is provided with a first heel cushioning part 22, which can wrap the heel near the ankle to prevent heel chafing. The insole 30 has an arch cushioning part 31, which can support the arch of the foot. When children wear this type of children's shoe, their gait is more stable and walking is more comfortable.

[0048] The children's shoes provided in the embodiments of this utility model will now be described.

[0049] Please refer to the following: Figures 1 to 4 The children's shoes include a sole 10, an upper 20 located at the edge of the sole 10, and an insole 30 located on the surface of the sole 10. The insole 30 is provided with a raised arch cushioning part 31. The inner side of the upper 20 near the toe is provided with a toe cushioning part 21, and the inner side of the upper 20 near the heel is provided with a first heel cushioning part 22.

[0050] The sole 10 is the part of the children's shoe that contacts the ground. Specifically, the bottom surface of the sole 10 contacts the ground, while the front surface of the sole 10 supports the child's foot. Understandably, the sole 10 is used to protect and support the sole of the foot.

[0051] The upper 20 is located at the edge of the sole 10, and its outer surface forms the exterior structure of the children's shoe. Furthermore, the upper 20 is the main structural component that wraps around the foot in footwear products. It is typically located above the sole 10, covering the instep, toes, and heel area. Its core function is to provide foot protection, dynamic support, and a comfortable fit through material selection and structural design. The upper 20 has an inner and outer side; the inner side faces the foot, and the outer side faces outward. The toe area of ​​the upper 20 is located near the toes, and the heel area is located near the heel. A toe cushioning section 21 is located on the inner side of the upper 20 near the toe, protecting the child's toes, and a first heel cushioning section 22 is located on the inner side of the upper 20 near the heel, protecting the child's heel.

[0052] The insole 30 is located on the front of the sole 10. The insole 30 can cushion the impact of the sole 10 on the sole of the foot when walking, making the children's shoes more comfortable to wear. The insole 30 is provided with a raised arch cushioning part 31. The arch cushioning part 31 protrudes from the surface of the insole 30 and can support and cushion the child's arch, effectively balancing the three points of force on the medial arch, lateral arch and transverse arch, thereby keeping the foot healthy while walking.

[0053] The children's shoes in the above embodiments include a sole 10, an upper 20, and an insole 30. The insole 30 has an arch cushioning part 31, which can cushion and support the arch of the foot. The upper 20 has a toe cushioning part 21 at the toe and a first heel cushioning part 22 at the heel. This allows the toes to be wrapped and cushioned to a certain extent by the toe cushioning part 21 during walking, and the heel to be wrapped and cushioned by the first heel cushioning part 22, thereby improving the comfort of the children's shoes. This example provides stress cushioning areas at least at three locations on the foot: the instep, the heel, and the arch of the foot, to reduce the contact stress on the foot from different directions during walking, effectively improving walking comfort and strengthening foot protection.

[0054] In some embodiments of this utility model, the upper 20 and the sole 10 can be fixedly connected by sewing, gluing or other methods.

[0055] Please refer to some embodiments of this utility model. Figure 4The length of the insole 30 is positively correlated with the thickness of the arch cushioning part 31. Understandably, the longer the insole 30, the thicker the arch cushioning part 31; conversely, the shorter the insole 30, the thinner the arch cushioning part 31. Specifically, a longer insole 30 indicates a larger shoe size, a more mature and generally heavier user group, thus requiring a thicker arch cushioning part 31 for cushioning and support. Conversely, a shorter insole 30 indicates a smaller shoe size, a younger and generally lighter user group, thus requiring a thinner arch cushioning part 31 for cushioning and support. It should be noted that while the length of the insole 30 is positively correlated with the thickness of the arch cushioning part 31, this does not mean that the length of the insole 30 and the thickness of the arch cushioning part 31 are directly proportional; they may not be directly proportional.

[0056] In some possible embodiments, some users have longer feet, requiring larger shoe sizes and insoles, but are lighter in weight. In this case, the elastic potential energy requirement for the arch cushioning is lower, and a thinner arch cushioning section can be used. Conversely, some users have shorter feet, requiring smaller shoe sizes and insoles, but are heavier in weight. In this case, the elastic potential energy requirement for the arch cushioning is higher, and a thicker arch cushioning section can be used. The arch cushioning section provided in this embodiment is mainly used to support the human arch, providing cushioning against the force of the ground during walking. A portion of the force of the foot contacting the ground comes from the user's own weight, and the arch cushioning section can at least partially offset the stress exerted by the user's own weight on the arch during foot contact.

[0057] In some possible embodiments, the user's weight is positively correlated with the thickness of the arch cushioning portion 31. Understandably, the greater the user's weight, the greater the thickness of the arch cushioning portion 31; conversely, the smaller the user's weight, the smaller the thickness of the arch cushioning portion 31. Specifically, a greater user weight indicates greater pressure from their own weight on the sole of their foot. When the foot contacts the ground, the foot experiences greater stress from the ground. In this case, a thicker arch cushioning portion 31 is needed to support and cushion the arch of the foot, reducing or offsetting the reverse pressure of this stress on the foot and improving foot comfort. Conversely, a smaller user weight indicates less pressure from their own weight on the sole of their foot. When the foot contacts the ground, the foot experiences less stress from the ground. In this case, a thinner arch cushioning portion 31 is needed to support and cushion the arch of the foot, preventing the arch cushioning portion 31 from being too thick and compressing the foot's accommodating space.

[0058] In some embodiments, when the user's weight is in the range of 10kg to 30kg, the thickness of the arch cushioning part 31 ranges from 6.8mm to 8.8mm; and the thickness of the arch cushioning part 31 increases by 1mm for every 1kg to 2kg increase in user weight. When the user's weight is 30kg or more, the thickness of the arch cushioning part 31 is greater than 8.8mm; and the thickness of the arch cushioning part 31 increases by 1mm for every 2kg to 3kg increase in user weight. That is, when the user's weight is 10kg, the thickness of the arch cushioning part 31 is 7.1mm; when the user's weight is 16kg, the thickness of the arch cushioning part 31 is 7.7mm; when the user's weight is 32kg, the thickness of the arch cushioning part 31 is 8.9mm; and when the user's weight is 36kg, the thickness of the arch cushioning part 31 is 9.1mm. Children's feet grow rapidly in their early years, and their weight changes quickly, requiring frequent shoe replacements. In later childhood, as the feet become more fully formed, the most comfortable arch cushioning 31 needs to be selected based on individual weight. Therefore, this example sets the thickness increase of the arch cushioning 31 for different weight stages. The increase is set larger in the early stages to accommodate rapid growth, while the increase is smaller in the later stages to provide sufficient foot support within the shoe cavity formed by the insole 30 and the upper 20, preventing the upper from compressing the instep and improving comfort at both the arch and instep. This example aims to provide a companion-style growing children's shoe that can be designed with different arch cushioning 31 thicknesses according to different weights, thus providing appropriate elastic cushioning for the user's arch.

[0059] Please refer to some embodiments of this utility model. Figure 4 The ratio of the length of the insole 30 to the thickness of the arch cushioning portion 31 ranges from 17 to 26. In this embodiment, the thickness of the arch cushioning portion 31 is measured in mm, and the length of the insole 30 is also measured in mm. If the ratio of the length of the insole 30 to the thickness of the arch cushioning portion 31 is too small, the arch cushioning portion 31 may over-support the wearer's arch, excessively lifting the arch. Furthermore, due to the wearer's weight, the compression of the arch cushioning portion 31 is relatively small, resulting in insufficient comfort. If the ratio of the length of the insole 30 to the thickness of the arch cushioning portion 31 is too large, the arch cushioning portion 31 may fail to support the wearer's arch, thus lacking arch support. Therefore, this embodiment sets the ratio of the length of the insole 30 to the thickness of the arch cushioning portion 31 to be between 17 and 26.

[0060] In some embodiments, the ratio of the length of the insole 30 to the thickness of the arch cushioning portion 31 is 17, 18, 22, 22.8, 24.7, 26, etc.

[0061] In some embodiments of this invention, the thickness of the arch cushioning portion 31 ranges from 6.8 mm to 10 mm. It should be noted that the thickness of the arch cushioning portion 31 is the sum of the thickness of the insole 30 itself and the height of the arch cushioning portion 31 protruding from the surface of the insole 30. If the thickness of the arch cushioning portion 31 is too small, it cannot effectively support the arch; if the thickness of the arch cushioning portion 31 is too large, it will cause significant arch deformation, affecting children's growth and development.

[0062] In some embodiments, the thickness of the arch cushioning portion 31 is 6.8mm, 7mm, 7.1mm, 7.3mm, 7.5mm, 7.7mm, 8.1mm, 8.3mm, 8.7mm, 9.9mm, 10mm, etc.

[0063] In some embodiments, the arch cushioning part 31 has a thickness of 7.1 mm and the insole 30 has a length of 13 cm, suitable for children weighing 9 kg to 11 kg. Alternatively, the arch cushioning part 31 has a thickness of 7.3 mm and the insole 30 has a length of 13 cm, suitable for children weighing 11 kg to 14 kg. Alternatively, the arch cushioning part 31 has a thickness of 7.7 mm and the insole 30 has a length of 17 cm, suitable for children weighing 14 kg to 18 kg. Alternatively, the arch cushioning part 31 has a thickness of 8.1 mm and the insole 30 has a length of 19 cm, suitable for children weighing 18 kg to 23 kg. Alternatively, the arch cushioning part 31 has a thickness of 8.5 mm and the insole 30 has a length of 21 cm, suitable for children weighing 22 kg to 30 kg. Alternatively, the arch cushioning part 31 has a thickness of 8.9 mm and the insole 30 has a length of 22 cm, suitable for children weighing 27 kg to 38 kg. Alternatively, the arch support 31 is 10.3mm thick and the insole 30 is 23cm long, suitable for children weighing 32kg to 49kg.

[0064] In some embodiments of this invention, the density range of the arch cushioning part 31 is 42 kg / m³. 3 Up to 60kg / m 3 The hardness of the arch cushioning part 31 ranges from 10HD to 30HD. When the density and hardness of the arch cushioning part 31 are within the above range, the arch cushioning part 31 not only provides good support for the arch of the foot but also has good rebound force, thus cushioning the arch. For example, the density of the arch cushioning part 31 is 42 kg / m³. 3 45kg / m 3 60kg / m 3 The hardness of the arch cushioning part 31 is 10HD, 20HD, 30HD, etc.

[0065] In some embodiments of this invention, the thickness of the arch cushioning portion 31 is positively correlated with its resilience. Understandably, the greater the thickness of the arch cushioning portion 31, the better its resilience, and the better the arch cushioning effect for heavier individuals.

[0066] Please refer to some embodiments of this utility model. Figures 1 to 3 The thickness of the first heel cushioning portion 22 on the side near the sole 10 is less than the thickness of the side of the first heel cushioning portion 22 away from the sole 10. When the children's shoe is placed on the ground, the first heel cushioning portion 22 has a vertical structure, with one side of the first heel cushioning portion 22 close to the ground (i.e., the side close to the sole 10) and the other side of the first heel cushioning portion 22 away from the ground (i.e., the side away from the sole 10). Understandably, the thickness of the top of the first heel cushioning portion 22 is greater than the thickness of its bottom.

[0067] Generally, the heel protrudes more than the ankle. When children wear children's shoes, the protruding part of the heel exerts greater pressure on the upper 20. Therefore, the thickness of the first heel cushioning part 22 on the side closer to the sole 10 is set to be less than the thickness of the side farther from the sole 10. The protruding part of the heel is matched with the thinner side, and the part of the heel closer to the ankle is matched with the thicker side, which conforms to the structural characteristics of the human heel. In addition, the thicker side of the first heel cushioning part 22 away from the sole 10 provides a larger cushioning space between the foot and the upper edge of the heel of the upper 20, so as to prevent the upper edge of the heel of the upper 20 from repeatedly rubbing against the skin of the ankle.

[0068] In some embodiments, the surface of the first heel cushioning portion 22 is sloped, and the thickness of the first heel cushioning portion 22 gradually changes, making the contact between the heel and the first heel cushioning portion 22 more comfortable, which can improve the comfort of children's shoes.

[0069] In some embodiments, the surface of the first heel cushioning portion 22 is arc-shaped, and the thickness of the first heel cushioning portion 22 also varies gradually, which can improve the comfort of children's shoes.

[0070] Please refer to some embodiments of this utility model. Figures 1 to 3 The edge of the first heel cushioning part 22 near the sole 10 is curved. The curved shape is a non-linear structure, such as an arc or a wave.

[0071] By setting the edge of the first heel cushioning part 22 near the sole 10 to be curved, the first heel cushioning part 22 fits the ankle better, increases the wrapping effect, and improves the comfort of the ankle.

[0072] In some embodiments, the first heel cushioning portion 22 is cloud-shaped, and the edge of the first heel cushioning portion 22 near the sole 10 is wavy.

[0073] In some embodiments, the edge of the first heel cushioning portion 22 near the sole 10 is an arc shape, a parabola shape, or the like.

[0074] Please refer to some embodiments of this utility model. Figure 4 The insole 30 includes a cushioning layer 33 with rebound capability and a fabric layer 34 covering the surface of the cushioning layer 33. The cushioning layer 33 has a raised arch cushioning part 31 at the arch position. The cushioning layer 33 has rebound capability, meaning that the cushioning layer 33 can deform under pressure and can also rebound quickly when there is no pressure. Therefore, during normal walking or running and jumping, the insole 30 can provide cushioning for the foot, assist walking, improve foot comfort, and reduce the impact of external forces on the foot. The fabric layer 34 covers the surface of the cushioning layer 33 and mainly undertakes the basic function of contact with the sole of the foot. The fabric layer 34 is generally made of cloth. The soft and skin-friendly material (such as cotton, chemical fiber blends, or antibacterial fibers) can reduce friction between the foot and the insole 30 and avoid skin abrasion. At the same time, the pore structure of the fabric can absorb moisture and wick away sweat to keep the sole of the foot dry, and the weave texture can increase friction to prevent the foot from sliding inside the shoe and improve walking stability.

[0075] By incorporating the fabric layer 34, the skin-friendliness of the insole 30 can be enhanced, allowing it to absorb moisture and wick away sweat, keeping the soles of the feet dry and reducing bacterial growth. Additionally, the raised arch support 31 provides effective support for the arch of the foot, which is beneficial for the development of children's arches and makes walking more stable.

[0076] In some embodiments, the buffer layer 33 and the fabric layer 34 can be fixed by molding, so that the fabric layer 34 is fixed on the surface of the buffer layer 33 and forms an integral part with the buffer layer 33.

[0077] In some embodiments, the fabric layer 34 may be composed of Lycra, mesh, microfiber fleece, knitted fabric, or other materials, and may have certain moisture absorption and perspiration wicking functions.

[0078] In some embodiments, the buffer layer 33 may be made of materials with resilience such as foam, latex, memory foam, and EVA, and has a certain buffering and protective effect.

[0079] For example, the fabric layer 34 is made of Lycra material and the cushioning layer 33 is made of foam; or, the fabric layer 34 is made of mesh material and the cushioning layer 33 is made of latex; or, the fabric layer 34 is made of microfiber fleece material and the cushioning layer 33 is made of memory foam; or, the fabric layer 34 is made of knitted fabric and the cushioning layer 33 is made of EVA.

[0080] In some embodiments, the texture of the fabric layer 34 can be plain weave, horizontal weave, dot pattern, checkered pattern, or irregular pattern, etc.

[0081] In some embodiments, the arch cushioning portion 31 is made of the same material as the cushioning layer 33, thus reducing the manufacturing cost of the insole 30. In other embodiments, the arch cushioning portion 31 may be made of a different material than the cushioning layer 33.

[0082] Please refer to some embodiments of this utility model. Figure 4 The thickness of the cushioning layer 33 is 4mm ± 0.5mm. If the cushioning layer 33 is too thick, it may take up too much space inside the shoe, restricting foot movement, especially in the forefoot and toes, which can lead to compression and discomfort or even pain after prolonged wear. Additionally, an overly thick insole 30 may make the shoe too tight, affecting blood circulation and causing symptoms such as numbness or swelling in the feet. If the cushioning layer 33 is too thin, it may not provide sufficient cushioning, especially during running or prolonged standing, as the pressure on the sole of the foot cannot be effectively distributed, potentially leading to plantar fasciitis or heel pain. Insufficient support may also cause fatigue or worsen flat feet due to lack of arch support. To balance cushioning capacity and comfort, the thickness of the cushioning layer 33 can be set to 4mm ± 0.5mm.

[0083] In some embodiments, the thickness of the buffer layer 33 is 3.5 mm, 3.7 mm, 4 mm, 4.2 mm, 4.5 mm, etc.

[0084] In some embodiments of this invention, the density of the buffer layer 33 is 80 kg / cm³. 3 ±10kg / cm 3 Insoles with an excessively high density (too hard material) will experience reduced cushioning performance and uneven pressure distribution on the sole of the foot. During walking, key areas such as the arch and heel are prone to excessive impact due to a lack of elastic support, potentially leading to plantar fasciitis or joint strain. Conversely, insoles with too low a density (too soft material) will lack support, causing them to collapse and deform easily, failing to stabilize the arch. Long-term use may exacerbate flat feet or foot fatigue, and the poor material rebound will accelerate wear and reduce lifespan. To balance cushioning and comfort, the density of the cushioning layer 33 can be set to 80 kg / cm². 3 ±10kg / cm 3 .

[0085] Please refer to some embodiments of this utility model. Figure 4 The thickness of the buffer layer 33 is 4 mm ± 0.5 mm; and / or, the density of the buffer layer 33 is 80 kg / cm³. 3 ±10kg / cm 3For example, the thickness of buffer layer 33 is 4 mm, and the density of buffer layer 33 is 80 kg / cm³. 3 .

[0086] Please refer to some embodiments of this utility model. Figure 4 The height of insole 30 is 3.5mm to 4.5mm. For example, the height of insole 30 is 3.5mm, 4mm, 4.3mm, 5.3mm, etc.

[0087] Please refer to some embodiments of this utility model. Figure 4 The density of the insole 30 is 80T and the hardness is 25HD.

[0088] Please refer to some embodiments of this utility model. Figure 4 The buffer layer 33 has a raised second heel buffer portion 32 at the heel position. The second heel buffer portion 32 is used to support and cushion the heel, and the second heel buffer portion 32 is raised relative to the surface of the buffer layer 33.

[0089] By setting a second heel cushioning part 32 at the heel position of the cushioning layer 33, the impact force generated by the heel landing during walking and running can be effectively absorbed, reducing impact damage to the plantar fascia, ankle joint and knee; at the same time, through the moderate density design, it conforms to the heel contour to provide stable support, prevent excessive inward or outward pronation of the foot, maintain gait balance, and distribute the pressure point of the heel to avoid local wear or fatigue accumulation, thereby improving the comfort and foot protection of long-term walking.

[0090] In some embodiments, the second heel cushioning portion 32 is made of the same material as the cushioning layer 33, thus reducing the manufacturing cost of the insole 30. In other embodiments, the second heel cushioning portion 32 may be made of a different material than the cushioning layer 33.

[0091] Please refer to some embodiments of this utility model. Figure 4 The density of the second heel cushioning part 32 is between that of the cushioning layer 33 and the arch cushioning part 31. The cushioning layer 33 has a higher density, resulting in a tighter compression, greater durability, and a longer service life. The arch cushioning part 31 has a relatively lower density, is taller, has better resilience, and provides better elastic support for the arch. The density of the second heel cushioning part 32, being between that of the cushioning layer 33 and the arch cushioning part 31, strikes a balance between resilience and durability.

[0092] In some embodiments, the cushioning layer 33, the second heel cushioning portion 32, and the arch cushioning portion 31 are made of the same material, but their densities are different. For example, the cushioning layer 33, the second heel cushioning portion 32, and the arch cushioning portion 31 are all made of foam.

[0093] In some embodiments, the cushioning layer 33, the second heel cushioning portion 32, and the arch cushioning portion 31 are made of different materials, and correspondingly, their densities are different. For example, the cushioning layer 33 is made of foam, the second heel cushioning portion 32 is made of latex, and the second heel cushioning portion 31 is made of EVA.

[0094] Please refer to some embodiments of this utility model. Figure 4 The outer edge of the arch cushioning portion 31 coincides with the edge of the insole 30. The inner edge of the arch cushioning portion 31 includes multiple sequentially connected arc-shaped segments 311, with a recessed structure formed at the connection between two adjacent arc-shaped segments 311. The outer edge of the arch cushioning portion 31 is the edge closer to the edge of the insole 30, and the inner edge of the arch cushioning portion 31 is the edge closer to the middle of the insole 30. The inner edge of the arch cushioning portion 31 includes multiple sequentially connected arc-shaped segments 311, with a recessed structure formed at the connection between two adjacent arc-shaped segments 311. Understandably, the inner edge of the arch cushioning is roughly wavy, with each wavy unit being the same or different in size, and a recessed structure formed between two adjacent wavy units.

[0095] By setting the inner edge of the arch cushioning part 31 as multiple sequentially connected arc segments 311, a concave structure is formed between two adjacent arc segments 311. This not only increases the contact area between the arch cushioning part 31 and the arch of the foot, reducing the pressure on the arch cushioning part 31 during exercise and reducing the deformation of the arch cushioning part 31 under pressure, but also shortens the rebound time of the arch cushioning part 31 and improves the comfort of the insole 30.

[0096] In some embodiments, the arch cushioning portion 31 is cloud-shaped, which can enhance the design and texture of the insole 30.

[0097] In some embodiments of this invention, the sole 10 has a heel near the heel, and the height of the heel is directly proportional to the thickness of the toe cushioning part 21. A higher heel constitutes a high-heeled shoe. When children wear such high-heeled shoes, the pressure is concentrated on the toes, making them prone to chafing and, over time, toe deformities. The higher the heel, the greater the pressure on the toes, and the thicker the toe cushioning part 21 should be to provide better support and protection. Conversely, a lower heel results in greater pressure on the toes, requiring a thinner toe cushioning part 21 and more space for toe movement between the upper 20 and the sole 10.

[0098] In some embodiments of this utility model, the inner side of the upper 20 has an inner lining layer, and the toe cushioning part 21 is located between the upper 20 and the inner lining layer. The function of the inner lining layer is as follows: the inner lining layer is made of a soft and skin-friendly material, which is in direct contact with the instep. It can reduce friction and the risk of blisters through abrasion reduction and cushioning, while conforming to the curve of the foot to enhance the wrapping and stabilize the foot posture; the breathable and sweat-wicking inner lining structure (such as mesh or antibacterial fiber) can quickly wick away the moisture and heat of the foot, maintain a dry environment inside the shoe, and prevent odor and bacterial growth; the inner lining layer can also fix the toe cushioning part 21, eliminating the need for other structures to fix the toe cushioning part 21.

[0099] In some embodiments of this utility model, the toe cushioning part 21 is shaped like a cloud or the like.

[0100] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
