[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, the cushioning function of traditional insoles largely relies on the elasticity of materials, such as layering cushioning materials like foam or gel within the insole. However, these designs are prone to material fatigue and aging after prolonged use, leading to a decrease in cushioning effectiveness. Furthermore, the arch area experiences complex dynamic forces during walking, making it difficult for a single material to effectively disperse impact forces.

[0021] Based on this, this application provides a shock-absorbing insole, which aims to solve the technical problem of poor shock absorption performance of insoles in the prior art.

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

[0023] refer to Figures 1 to 3 A shock-absorbing insole includes: a fabric layer 1 for contacting the foot; a shock-absorbing layer 2 disposed below the fabric layer 1, the bottom surface of the shock-absorbing layer 2 having a plurality of groove structures 20 in the arch area, the groove structures 20 being used to provide shock absorption through structural deformation when the foot is subjected to force; and a patch layer 3 disposed on the bottom surface of the shock-absorbing layer 2, the patch layer 3 including two patches 30 disposed in the forefoot area and the heel area respectively, the groove structures 20 being exposed between the two patches 30.

[0024] The fabric layer 1 can be made of breathable and antibacterial material, and it comes into direct contact with the foot, providing a comfortable feel. The cushioning layer 2 provides basic cushioning through material elasticity. The bottom surface of the cushioning layer 2 has several groove structures 20 in the area corresponding to the arch of the foot. These groove structures 20 weaken the material stiffness in this area, forming a structural cushioning area that is easy to bend and deform, used to absorb and disperse impact force through its own deformation when the foot is subjected to force. The two patches 30 of the patch layer 3 provide support and wear resistance, and the two patches 30 are spaced apart from each other on the bottom surface of the cushioning layer 2, so that the groove structure 20 is exposed between the two patches 30, that is, the patches 30 do not cover the groove structure 20, ensuring that the groove structure 20 can achieve sufficient deformation.

[0025] As a preferred embodiment, refer to Figure 1 Each groove structure 20 extends along the length of the damping layer 2, and different groove structures 20 are arranged along the width of the damping layer 2.

[0026] In this design, a single groove structure 20 extends along the length of the cushioning layer 2, and all groove structures 20 are arranged along the width of the cushioning layer 2, so that the bending deformation of the insole conforms to the forward direction of the foot, so as to guide and absorb the impact force in the forward direction and improve the cushioning effect.

[0027] In a preferred embodiment, the depth of the groove structure 20 is 1 / 4 to 1 / 2 of the thickness of the damping layer 2.

[0028] The depth of the groove structure 20 is designed to ensure that the insole has sufficient material deformation to effectively absorb energy when it is under pressure, while avoiding the overall structural fragility of the cushioning layer 2 due to excessive groove depth, thus ensuring the durability of the insole.

[0029] In one specific implementation, the depth of the groove structure 20 is 1 / 4, 1 / 3, 5 / 12, or 1 / 2 of the thickness of the damping layer 2.

[0030] In a preferred embodiment, the bottom of the groove structure 20 is provided with a number of ventilation holes, and the different ventilation holes are arranged along the length of the groove structure 20.

[0031] The ventilation holes improve the breathability and moisture-wicking properties of the insole, making it easier to keep your feet dry.

[0032] As a preferred embodiment, refer to Figure 3 The cushioning layer 2 includes a raised structure 21 adapted to the arch of the foot, which supports the arch of the foot.

[0033] Among them, the raised structure 21 supports the arch of the foot, helps maintain the normal physiological curvature of the foot, distributes the pressure on the sole of the foot, reduces the load on ligaments and muscles, thereby preventing and relieving foot fatigue.

[0034] In a preferred embodiment, the shock-absorbing layer 2 is made of any one of E-TPU material, PU material, sponge material and latex material.

[0035] Taking E-TPU material as an example, the lightweight, high resilience and energy return characteristics of E-TPU material enable the shock-absorbing layer 2 to compress and absorb energy at the moment of impact and then return to its original shape.

[0036] In a preferred embodiment, fabric layer 1 is formed by bonding or weaving fabrics with different properties together.

[0037] Among them, fabric layer 1 adopts a composite process of fabrics with different properties to achieve the integration of fabric performance.

[0038] In a preferred embodiment, fabrics with different properties include cotton and synthetic fibers, with synthetic fibers including at least polyester and nylon.

[0039] Among them, the fabric layer 1 can adopt a double-layer composite process, using a combination of cotton and polyester fiber or nylon, making full use of the complementary advantages of cotton's moisture absorption, breathability, comfort and softness and synthetic fiber's strength and wear resistance, thereby improving the hygiene and durability of the insole.

[0040] In a preferred embodiment, the fabric layer 1 is fixedly connected to the top surface of the shock-absorbing layer 2 by adhesive bonding.

[0041] The adhesive method used to bond the fabric layer 1 ensures that the fabric layer 1 remains flat, wrinkle-free, and does not shift during the entire use process, thus avoiding friction and discomfort caused by interlayer slippage.

[0042] In a preferred embodiment, the two patches 30 are fixedly connected to the bottom surface of the shock-absorbing layer 2 by adhesive.

[0043] The adhesive method of patch 30 ensures that patch 30 can still adhere firmly when subjected to impact and friction, stably perform its supporting and wear-resistant functions, and ensure the overall structural integrity of the insole.

[0044] In a preferred embodiment, patch 30 is made of any one of EVA material, PU material, silicone material and latex material.

[0045] Taking EVA material as an example, EVA material has good flexibility and support strength, which can provide necessary cushioning and support for the forefoot and heel areas, without excessively increasing the weight or hardness of the insole.

[0046] As an example of insole use, during walking or running, the foot strikes the ground, and pressure is transmitted to the insole. The arch area experiences complex bending and impact forces during movement. At this time, the grooved structure 20 of the cushioning layer 2 can freely bend and deform, efficiently absorbing impact energy and dispersing pressure in all directions. This structural deformation, combined with the material elasticity of the cushioning layer 2 itself and the stable support provided by the front and rear patches 30, together achieves the cushioning effect.
