Description

Technical Field

[0001] This application relates to the field of footwear accessories technology, and in particular to a multi-layered insole with internal height increase, shock absorption support, and anti-torsion functions. Background Technology

[0002] Currently, many insole products on the market have relatively limited functions, typically focusing only on one of the following: cushioning, height increase, or anti-torsion. For example, ordinary height-increasing insoles mainly achieve physical height increase by increasing the thickness of the padding layer, but they often lack cushioning and foot support, resulting in poor wearing comfort. Insoles with cushioning functions often lack sufficient lateral support and anti-torsion performance, making it difficult to protect the feet during exercise and posing a risk of ankle sprains.

[0003] Therefore, how to provide an insole that can combine all the above functions is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application provides a multi-layered insole with internal height-increasing, shock-absorbing support, and anti-torsion functions, which not only meets the user's need for height increase but also improves the wearing comfort of the insole.

[0005] The technical solution adopted in this application is as follows: A multi-layered insole with internal height-increasing, shock-absorbing support, and anti-torsion functions, characterized in that the insole comprises: The layers arranged from top to bottom are: a contact layer, a shock-absorbing support layer, and a torsion-resistant reinforcement layer. The contact layer has a forefoot area, an arch area and a heel area corresponding to the human foot. A recessed structure is provided in the forefoot area, a first protruding structure is provided in the arch area and a second protruding structure is provided in the heel area. The shock-absorbing support layer has a preset thickness; The anti-torsion reinforcement layer includes an anti-torsion structure, which is attached to the shock-absorbing support layer and has a harderness than that of the shock-absorbing support layer.

[0006] Preferably, the contact layer includes a breathable layer and a fabric layer covering the breathable layer, the recessed structure is formed in the breathable layer, and the first protruding structure and the second protruding structure are both formed in the breathable layer.

[0007] Preferably, the breathable layer is made of sponge material.

[0008] Preferably, the fabric layer is made of woven fabric and / or leather material.

[0009] Preferably, the shock-absorbing support layer includes a rebound layer and a support layer surrounding a portion of the rebound layer.

[0010] Preferably, the support layer includes a bottom surface and a sidewall surface extending vertically from the edge of the bottom surface, wherein the bottom surface and the sidewall surface define a receiving space for providing the rebound layer.

[0011] Preferably, the resilience layer is made of polyether material.

[0012] Preferably, the support layer is made of polyurethane material.

[0013] Preferably, the anti-torsion structure includes an integrally formed base plate and side plates surrounding the base plate, the base plate being attached to the bottom surface of the shock-absorbing support layer, and the side plates being attached to the side surface of the shock-absorbing support layer.

[0014] Preferably, the anti-torsion reinforcement layer further includes at least two flexible anti-slip components; The base plate has mounting holes, one of the flexible anti-slip components is disposed in the mounting holes and is attached to the bottom surface of the shock-absorbing support layer, and the other flexible anti-slip component is attached to the bottom surface of the shock-absorbing support layer in a direction away from the anti-torsion structure.

[0015] According to the specific embodiments provided in this application, the following technical effects are disclosed: The technical solution of this application provides a multi-layered insole with internal height enhancement, shock absorption support, and anti-torsion functions, comprising: a contact layer, a shock absorption support layer, and an anti-torsion reinforcement layer arranged sequentially from top to bottom; the contact layer has a forefoot area, an arch area, and a heel area corresponding to the human foot, with a recessed structure in the forefoot area, a first protruding structure in the arch area, and a second protruding structure in the heel area; the shock absorption support layer has a preset thickness; the anti-torsion reinforcement layer includes an anti-torsion structure, which is attached to the shock absorption support layer and has a harderness than that of the shock absorption support layer. In this design, the concave structure in the forefoot provides anti-slip and support for the toes during walking and exercise, while the raised structures at the arch and heel provide support for the arch and heel respectively, thereby improving the support and fit of the insole and enhancing wearing comfort. At the same time, the preset thickness of the cushioning support layer provides a good cushioning feel while achieving a physical height increase effect.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] As described in the background section, some insole products on the market currently have relatively limited functions, typically focusing only on one of the following: cushioning, height increase, or anti-torsion. For example, ordinary height-increasing insoles mainly achieve physical height increase by increasing the thickness of the padding layer, but they often lack cushioning and foot support, resulting in poor wearing comfort. Insoles with cushioning functions often lack sufficient lateral support and anti-torsion performance, making it difficult to protect the feet during exercise and posing a risk of ankle sprains.

[0021] Based on this, this application provides a multi-layered insole with internal height increase, shock absorption support, and anti-torsion functions, aiming to solve the technical problem that existing insole products only focus on one function and cannot cover all functions.

[0022] The embodiments of this application will be analyzed in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 4 A multi-layered insole with internal height enhancement, shock absorption, and anti-torsion functions includes: a contact layer 1, a shock absorption support layer 2, and an anti-torsion reinforcement layer 3 arranged sequentially from top to bottom; the contact layer 1 has a forefoot area, an arch area, and a heel area corresponding to the human foot, with a recessed structure 100 in the forefoot area, a first protruding structure 101 in the arch area, and a second protruding structure 102 in the heel area; the shock absorption support layer 2 has a preset thickness; the anti-torsion reinforcement layer 3 includes an anti-torsion structure 30, which is attached to the shock absorption support layer 2 and has a harderness than the shock absorption support layer 2.

[0024] By layering three different functional materials, the insole integrates height enhancement, cushioning support, and anti-torsion functions, solving the problem of single-function insoles. Specifically, the forefoot concave structure 100 provides anti-slip and support for the toes during walking and exercise, while the raised structures at the arch and heel provide support for the arch and heel respectively, thereby improving the insole's support and fit, and enhancing wearing comfort. At the same time, the preset thickness of the cushioning support layer 2 provides good cushioning while achieving a physical height increase effect. In addition, the anti-torsion reinforcement layer 3, with its higher rigidity, provides anti-torsion support for the overall structure of the insole, which can significantly reduce the risk of lateral rollover and ankle sprains caused by unstable landing or improper posture during exercise, thus improving sports protection performance.

[0025] As a preferred embodiment, refer to Figure 1 and Figure 2 The contact layer 1 includes a breathable layer 10 and a fabric layer 11 covering the breathable layer 10. The recessed structure 100 is formed in the breathable layer 10, and the first protruding structure 101 and the second protruding structure 102 are both formed in the breathable layer 10.

[0026] The insole features an independent breathable layer 10 and a fabric layer 11. The breathable layer 10 is used to create a three-dimensional structure that fits the foot, while the fabric layer 11 provides a skin-friendly, wear-resistant, and moisture-wicking contact surface. This ensures foot support and a comfortable fit while improving the durability and wearing comfort of the insole.

[0027] In a preferred embodiment, the breathable layer 10 is made of sponge material.

[0028] Among them, the sponge material is soft, breathable and easy to shape, so that the foot can get a soft touch when it comes into contact with the insole. At the same time, the porous structure facilitates air circulation, keeps the soles of the feet dry, and can adapt to the pressure of the soles of the feet through compression deformation, thus improving the fit.

[0029] In a preferred embodiment, the fabric layer 11 is made of woven and / or leather materials.

[0030] The fabric material is breathable and moisture-wicking, further enhancing comfort, while the leather material is more upscale, durable, and easy to clean. The fabric layer 11 can be made of a mixture of different materials or a single material, providing a variety of material options to meet different usage scenarios and user preferences.

[0031] As a preferred embodiment, refer to Figure 1 The shock-absorbing support layer 2 includes a rebound layer 20 and a support layer 21 surrounding a portion of the rebound layer 20.

[0032] The rebound layer 20 is mainly used to absorb impact energy and provide a soft feel. Its surrounding support layer 21 forms a stable frame to prevent excessive lateral movement of the foot inside the shoe, ensuring stability in the height-increasing state and achieving a soft but not collapsing effect.

[0033] As an example, the vertical thickness of the cushioning support layer 2 in the heel area is set between 3 and 8 cm, and the heel area has a smooth slope transition to the forefoot area, thus realizing the physical height increase function of the insole.

[0034] As a preferred embodiment, refer to Figure 1 The support layer 21 includes a bottom surface 210 and a side wall surface 211 formed by extending vertically from the edge of the bottom surface 210. The bottom surface 210 and the side wall surface 211 define a receiving space for providing the spring layer 20.

[0035] The space formed by the bottom surface 210 and the side wall surface 211 not only firmly wraps and fixes the rebound layer 20 to prevent it from shifting during use, but the side wall surface 211 also provides lateral support for the overall structure of the insole, limiting abnormal deformation of the arch and heel during exercise and enhancing stability.

[0036] In a preferred embodiment, the resilience layer 20 is made of polyether material.

[0037] Polyether materials, in particular, possess resilience and resistance to compression deformation. They not only provide a soft feel when stepped on, but also maintain their original thickness and elasticity after long-term use, ensuring the durability of the insole's cushioning and height-increasing effect.

[0038] In a preferred embodiment, the support layer 21 is made of polyurethane material.

[0039] Polyurethane material has greater hardness and strength than polyether material. Using it as support layer 21 can provide a solid base for the entire cushioning support layer 2, ensuring that the rebound layer 20 can function in the containment space and preventing the insole from undergoing excessive and unstable deformation when subjected to force.

[0040] As a preferred embodiment, refer to Figure 1 and Figure 4 The anti-torsion structure 30 includes an integrally formed base plate 300 and a side plate 301 surrounding the base plate 300. The base plate 300 is attached to the bottom surface of the shock-absorbing support layer 2, and the side plate 301 is attached to the side surface of the shock-absorbing support layer 2.

[0041] Among them, the bottom plate 300 and the side plate 301 form an anti-torsion skeleton, which wraps around and reinforces the shock-absorbing support layer 2 from the bottom and sides, enhancing the overall anti-torsion strength of the insole, effectively resisting the tendency of the foot to protrude or supinate during exercise, and reducing the risk of spraining the ankle.

[0042] As a preferred embodiment, refer to Figure 1 , Figure 3 and Figure 4 The anti-torsion reinforcement layer 3 also includes at least two flexible anti-slip components 31; the base plate 300 has an installation hole 3000, one of the flexible anti-slip components 31 is located in the installation hole 3000 and is attached to the bottom surface of the shock-absorbing support layer 2, and the other flexible anti-slip component 31 is attached to the bottom surface of the shock-absorbing support layer 2 in a direction away from the anti-torsion structure 30.

[0043] Among them, the flexible anti-slip component 31 can prevent the insole from sliding inside the shoe cavity, ensuring that all design functions, such as support and anti-torsion, are in place precisely. At the same time, the flexible anti-slip component 31 can provide additional friction and cushioning when landing, improving grip and gait stability.

[0044] As a specific implementation, the anti-torsion structure 30 is made of TPU material.

[0045] The TPU material used is high-hardness TPU, which provides an anti-torsional framework for the entire insole to resist the torsional forces generated by the foot during exercise, thus achieving reliable anti-torsional protection. At the same time, it also has a certain degree of toughness and is not absolutely rigid. This ensures support while avoiding the risk of breakage under severe impact or repeated bending due to excessive hardness and brittleness of the material, thus ensuring the durability of the insole product.
