Abstract
Description
Technical Field
[0001] This application relates to the field of shoe accessory technology, and in particular to an arch support type shoe sole. Background Technology
[0002] Balancing support and comfort remains a technical challenge in contemporary footwear products. Traditional sole designs typically employ a single material or a simple combination of materials to achieve support, but this approach often fails to simultaneously meet the support requirements of high-intensity exercise and the comfort needs of everyday walking.
[0003] In recent years, many manufacturers have enhanced support by embedding rigid support plates (such as carbon fiber or nylon plates) inside key areas of the sole (such as the arch area). However, long-term use can lead to weakening of foot muscle function. If the support plate is too hard, it will affect the shock absorption and cushioning effect. If it is too soft, it will lose its support effect and is prone to collapse. Rigid structures (such as carbon fiber or nylon plates) can also easily restrict the natural extension and contraction of the arch. In addition, there are many acupoints on the sole of the foot. Using soles with added support plates may cause a feeling of pressure on the foot, affecting the natural gait and thus affecting the comfort of wearing the shoes. Summary of the Invention
[0004] To improve the wearing comfort of footwear products, this application provides an arch support type sole.
[0005] This application provides an arch support shoe sole, which adopts the following technical solution:
[0006] An arch support sole includes a sole body, a first density elastic part, and an anti-slip part. The first density elastic part is embedded in the inner foot side and bottom of the sole body. The density of the first density elastic part is higher than the density of the sole body. The anti-slip part is disposed on the bottom side of the sole body. The first density elastic part is used to support the wearer's arch.
[0007] By adopting the above technical solution, when wearing shoes with this sole, the first density elastic part can support the wearer's arch, directly acting on the underside of the arch to distribute arch pressure and inhibit pronation. The first density elastic part can stably support changes in arch pressure, while other areas maintain comfortable pressure distribution. The pressure on the sole is transferred through the sole itself, eliminating the need to add support plates inside the sole to achieve different support forces in different areas. At the same time, the elasticity and density of the first density elastic part achieve shock absorption and cushioning, reducing discomfort caused by rubbing against the foot, reducing foot fatigue, and improving wearing and walking comfort.
[0008] Optionally, the hardness range of the sole body is 35°-45° Shore A, and the hardness of the first density elastic part is higher than the hardness of the sole body.
[0009] By adopting the above technical solution, different force support for different zones of the foot can be achieved simultaneously by controlling the difference in hardness.
[0010] Optionally, the sole body includes a second density forefoot portion and a third density heel portion. The hardness range of the second density forefoot portion is 35°-40° Shore A, and the hardness range of the third density heel portion is 40°-45° Shore A. The hardness of the first density elastic portion is 5°-15° Shore A higher than that of the third density heel portion. The first density elastic portion, the second density forefoot portion, and the third density heel portion are integrally formed.
[0011] By adopting the above technical solutions, the second density forefoot section provides the forefoot with the greatest possible natural flexion freedom, and the third density heel section's stiffness setting can absorb most of the vertical impact force while providing heel support, reducing heel fatigue and improving wearing comfort. The integrated molding of the first density elastic section, the second density forefoot section, and the third density heel section can improve the overall compactness of the sole, and each part has good force transmission and rebound effect.
[0012] Optionally, the anti-slip part includes a forefoot pad and a heel pad, the forefoot pad being disposed at the bottom of the second density forefoot part, and the heel pad being disposed at the bottom of the third density heel part, the thickness of the heel pad being greater than the thickness of the forefoot pad.
[0013] By adopting the above technical solutions, the relatively thin forefoot pad can be used to maintain the flexible touch of the forefoot when walking or running, and the thickened heel pad can be used to cushion the impact force when the human heel hits the ground, thereby meeting the needs of frequent starting, stopping and turning, and adapting to different usage scenarios.
[0014] Optionally, a groove is provided in the middle of the bottom side of the third density heel portion, and an elastic block is provided in the groove. The density of the elastic block is higher than that of the third density heel portion, and the thickness of the elastic block is less than the depth of the groove.
[0015] By adopting the above technical solution, the thickness of the elastic block and the depth of the groove form a buffer space, thereby providing multiple buffering effects on the wearer's heel during use, reducing the vibration and impact on the heel and even the entire foot.
[0016] Optionally, the anti-slip portion further includes a convex pad that covers the end of the second density forefoot portion.
[0017] By adopting the above technical solution, the forward-convex pad can protect the wearer's toes and reduce the pain when kicking hard objects.
[0018] Optionally, an anti-wear pad is provided on the bottom side of the first density elastic part.
[0019] By adopting the above technical solution, the arch of the foot can be supported while also achieving wear resistance and anti-slip effects.
[0020] Optionally, the sidewall of the sole body is provided with several deformation grooves.
[0021] By adopting the above technical solution, the deformation groove can provide deformation buffer space for the sole body when walking.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. When wearing shoes with this sole, the first density elastic part can provide corresponding support at the wearer's arch, acting directly on the underside of the arch to distribute arch pressure and inhibit pronation. The first density elastic part can stably support changes in arch pressure, while other areas maintain comfortable pressure distribution. The pressure on the sole is transferred through the sole itself, eliminating the need to add support plates inside the sole to achieve different support pressure in different areas. At the same time, the elasticity and density of the first density elastic part provide shock absorption and cushioning, reducing discomfort caused by the jarring sensation on the sole, reducing foot fatigue, and improving wearing and walking comfort.
[0024] 2. The second density forefoot section allows for the greatest possible natural flexion freedom of the forefoot. The third density heel section's stiffness setting can absorb most of the vertical impact while providing heel support, reducing heel fatigue and improving wearing comfort. The integrated molding of the first density elastic section, the second density forefoot section, and the third density heel section can improve the overall compactness of the sole, and the various parts have good force transmission and rebound effect.
[0025] 3. The thickness of the elastic block and the depth of the groove form a buffer space, which provides multiple cushioning effects on the wearer's heel during use, reducing the vibration and impact on the heel and even the entire foot. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses an arch support type shoe sole.
[0033] Reference Figure 1 and Figure 2 An arch support sole includes a sole body 1, a first density elastic part 2, and an anti-slip part. The side of the sole body 1 corresponding to the inner arch of the wearer is the medial side, and the side of the sole body 1 corresponding to the outer arch of the wearer is the lateral side. The first density elastic part 2 is embedded in the medial side and the bottom of the sole body 1. The density of the first density elastic part 2 is higher than the density of the sole body 1. The anti-slip part is located on the bottom side of the sole body 1. When the wearer wears the sole, the position of the inner arch corresponds to the first density elastic part 2, which is used to support the wearer's arch.
[0034] The first density elastic part 2 is positioned to correspond to key areas of the inner side of the foot and the sole. When worn, the first density elastic part 2 forms good elastic support, which acts directly on the underside of the arch, effectively dispersing the pressure on the arch and inhibiting excessive pronation of the foot. It has a certain corrective effect on flat feet. When the sole touches the ground, the anti-slip part can provide grip by increasing the coefficient of friction. At the same time, the first density elastic part 2 can quickly respond to changes in arch pressure. The force on the sole is transferred through the sole itself, without the need to add additional support plates inside the sole to achieve different force distribution in different areas. This replaces the uncomfortable feel caused by traditional hard support plates, minimizes foot fatigue caused by delayed support, and improves wearing comfort.
[0035] The hardness range of the sole body 1 is 35°-45° Shore A, and the hardness of the first density elastic part 2 is higher than that of the sole body 1.
[0036] By controlling the hardness difference, the first density elastic part 2 forms an elastic support for the arch of the foot, improving the arch support stiffness, while the sole body 1 maintains the moderate softness of the rest of the parts, improving the comfort of the foot. The hardness difference design matches the pressure change curve in the human walking cycle. The first density elastic part 2 bears the main load in the support phase, while the sole body 1 releases stress in the off-ground phase, reducing the overall material fatigue wear of the sole.
[0037] Reference Figure 1 and Figure 3 The sole body 1 includes a second-density forefoot portion 11 and a third-density heel portion 12. The hardness range of the second-density forefoot portion 11 is 35°-40° Shore A, and the hardness range of the third-density heel portion 12 is 40°-45° Shore A. The hardness of the first-density elastic portion 2 is 5°-15° Shore A higher than that of the third-density heel portion 12. The first-density elastic portion 2, the second-density forefoot portion 11, and the third-density heel portion 12 are integrally molded and can be molded using existing processes such as dual-density injection molding, step-by-step injection foaming, and gradient foaming integrated process. The first-density elastic portion 2, the second-density forefoot portion 11, and the third-density heel portion 12 together form a complete sole. The first-density elastic portion 2 is made of PU material, and the second-density forefoot portion 11 and the third-density heel portion 12 are made of EVA material. The first-density elastic portion 2 extends to the inner foot side of the second-density forefoot portion 11 and the inner foot side of the third-density heel portion 12.
[0038] The second density forefoot section 11 features a low-hardness design, allowing the forefoot to bend naturally during the push-off phase. Compared to traditional homogeneous soles, this reduces energy loss during push-off. The third density heel section 12 has a hardness that matches the impact curve of the human calcaneus. In the initial contact phase, it absorbs most of the vertical impact force through compression, reducing heel fatigue. In the take-off phase, it releases elastic potential energy, improving the comfort of walking and running. The first density elastic section 2 provides support while also being elastic, providing a good cushioning and rebound effect for the arch area.
[0039] The anti-slip part includes a forefoot pad 31 and a heel pad 32. The forefoot pad 31 is located at the bottom of the second density forefoot part 11, and the heel pad 32 is located at the bottom of the third density heel part 12. The thickness of the heel pad 32 is greater than the thickness of the forefoot pad 31. The heel pad 32 is a wear-resistant rubber pad, and the forefoot pad 31 is an anti-slip rubber pad.
[0040] The thickened heel pad 32 can cushion the impact when the human heel hits the ground, while the relatively thin forefoot pad 31 can maintain a flexible feel and shorten the braking distance on wet and slippery surfaces. When walking, the forefoot pad 31 provides sufficient friction to meet the needs of frequent starting, stopping and turning. The forefoot pad 31 and the wear-resistant heel pad 32 can be used together to adapt to different scenarios.
[0041] A groove 121 is provided in the middle of the bottom side of the third density heel part 12. An elastic block 4 is provided on the groove wall of the groove 121. The elastic block 4 is fixed in the groove 121 by adhesive or hot melt glue. The density of the elastic block 4 is higher than that of the third density heel part 12. The thickness of the elastic block 4 is less than the depth of the groove 121. There is a gap between the bottom side of the elastic block 4 and the groove opening of the groove 121, thereby forming a buffer space.
[0042] The elastic block 4 provides elastic cushioning for the heel. When walking, the heel contacts the ground first, and the third density heel part 12 provides the first layer of cushioning. During the process of the third density heel part 12 being compressed and deformed, the elastic block 4 moves closer to the ground, and the cushioning space formed by the elastic block 4 and the groove 121 becomes smaller, achieving the second layer of cushioning. After the elastic block 4 contacts the ground, it also deforms, thus forming the third layer of cushioning. Therefore, the third density heel part 12, the groove 121 and the elastic block 4 can form a triple cushioning for the wearer's foot when walking, greatly reducing the vibration and impact on the heel and even the entire foot when walking, running or jumping.
[0043] The anti-slip part also includes a convex pad 33, which is disposed on the bottom side and end of the second density forefoot portion 11. The convex pad 33 is close to the end of the second density forefoot portion 11 away from the third density heel portion 12. The convex pad 33 covers the end of the second density forefoot portion 11 away from the third density heel portion 12. The hardness of the convex pad 33 is greater than the hardness of the forefoot pad 31. The hardness of the part of the convex pad 33 covering the third density heel portion 12 is greater than the hardness of the part of the convex pad 33 not covering the third density heel portion 12.
[0044] The forefoot pad 33 protects the toes, reducing pain when kicking hard objects, and provides further friction to the forefoot and toes while running.
[0045] The bottom side of the first density elastic part 2 is provided with an anti-wear pad 21. The bottom side of the anti-wear pad 21 is provided with anti-slip texture, so that the first density elastic part 2 provides support for the arch of the foot while playing a wear-resistant and anti-slip role, and plays a connecting and transitioning role for the forefoot and the front foot, thereby improving the stability of walking.
[0046] The second density forefoot portion 11 has several flexural grooves on its bottom side, which can provide flexibility for the forefoot to bend. The second density forefoot portion 11 and the third density heel portion 12 have several deformation grooves 13 on their side walls. The flexural grooves and deformation grooves 13 are connected. When walking, the deformation grooves 13 can provide deformation and cushioning space to increase the comfort of the foot. The deformation grooves 13 can also disperse the concentrated stress of the sole to multiple flexible units, thereby improving the durability of the sole.
[0047] The implementation principle of the arch support type sole in this application embodiment is as follows: The first density elastic part 2 is positioned to correspond to the key areas of the inner side of the foot and the bottom of the foot. When worn, the first density elastic part 2 provides good support and cushioning for the arch, which can suppress excessive pronation of the foot and has a certain corrective effect on flat feet. The low hardness of the second density forefoot part 11 can provide the forefoot with freedom of bending and reduce the energy loss of pushing off the ground. The third density heel part 12 absorbs most of the vertical impact force through compression in the initial contact with the ground, which can reduce the fatigue of the heel. Together with the elastic block 4, it can form a triple cushioning, which greatly reduces the vibration and impact on the heel and even the entire foot when walking, running or jumping, thereby avoiding foot fatigue caused by delayed support as much as possible and improving the comfort of wearing and walking.
[0048] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
