Description

Technical Field

[0001] This utility model relates to the field of footwear components technology, and in particular to an insole and shoe with arch support function. Background Technology

[0002] As people age, the structure of their feet undergoes significant changes. Common foot problems include collapsed arches, loose plantar fascia, and thinning of the fat pad. These issues lead to decreased foot support, uneven weight distribution during walking, resulting in foot pain, increased pressure on the knee and hip joints, and even affecting overall gait and balance. Most older adults experience forward foot tilt due to collapsed arches, causing the forefoot to bear more weight. Current athletic shoe designs are largely geared towards younger people and fail to adequately consider the specific needs of the elderly. Many athletic shoes are equipped with insoles that lack effective arch support, failing to fill the gap between the collapsed arch and the sole, and thus failing to distribute foot pressure, further exacerbating discomfort and health risks for older adults. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figures 1-7 This invention provides an insole with arch support function, comprising: an insole body 100 and a support plate 200. The support plate 200 is an arc-shaped structure conforming to the arch curve of the foot. The support plate 200 is disposed below the arch position of the insole body 100 to provide support. A first connecting portion is provided on the support plate 200, and a second connecting portion is provided on the insole body 100. The support plate 200 and the insole body 100 are detachably connected through the first and second connecting portions. The support plate 200, during exercise, not only prevents arch collapse but also disperses pressure on the sole of the foot, reducing foot fatigue. The support force of the support plate 200 can be appropriately adjusted by changing the connection position of the first and second connecting portions.

[0021] The support piece 200 has at least one connecting post 210 at each end along its length, and the connecting post 210 is a first connecting part. The bottom of the insole body 100 has at least two connecting holes 110 at each end along its length, corresponding to the position of each connecting post 210, and the connecting holes 110 are second connecting parts. The curvature of the support piece 200 is adjusted by inserting each connecting post 210 into the correspondingly spaced connecting holes 110.

[0022] When the connecting post 210 is inserted into a hole with a larger spacing, the support plate 200 is stretched or its suspended span increases; when inserted into a hole with a smaller spacing, the suspended span of the support plate 200 decreases. Users can adjust the elasticity themselves to intuitively feel the effect of different settings on the foot and adjust the curvature of the support plate 200 according to their own arch condition.

[0023] The support block 300 is fixedly connected to the bottom of the support plate 200 and located at the midfoot position. The support plate 200 includes a forefoot arc region, an arch region, and a heel arc region corresponding to the forefoot, arch, and heel positions of the insole body 100, respectively. The support block 300 includes a first support block 310, a second support block 320, and a third support block 330 respectively disposed below the forefoot arc region, arch region, and heel arc region. The upper surface of the support block 300 is in contact with the support plate 200. The first support block 310 has a Shore hardness of 50-55C. This medium-high hardness support block can reduce excessive deformation of the forefoot, improve push-off efficiency, and is suitable for distributing forefoot pressure and reducing fatigue during long periods of standing or walking. The second support block 320 has a Shore hardness of 40-45C. This medium-low hardness material combines flexibility and support, dynamically conforming to the arch curve, cushioning the impact of the ground during walking, and providing the necessary upward support force for the arch, preventing flat feet or arch fatigue. The third support block 330 has a Shore hardness of 35-45C, which is low to medium-low hardness. When the hardness is low, it can effectively absorb the impact of landing and reduce the shock to the ankle and knee joints. At the same time, when the hardness is medium, it can limit excessive inward or outward pronation of the heel and improve gait stability.

[0024] Support block 300 is made of EVA material. EVA has a low density and is lighter than TPU or metal support components, making it suitable for everyday wear. By adjusting the foaming agent content in EVA or blending it with other materials (such as rubber), the hardness of each support block 300 can be precisely controlled, achieving low-cost zoned functionality.

[0025] The design of setting a three-zone gradient hardness support block 300 at the bottom of the support plate 200, combined with the foot's anatomical structure and mechanical principles, achieves precise support and dynamic adaptation for the arch of the foot.

[0026] The support sheet 200 is made of rubber or TPU material. For example... Figure 12 The support sheet 200 has a hollow structure, which can reduce the amount of TPU material used.

[0027] The insole body 100 is located at the arch of the foot, arching upwards to conform to the arch. The arch arch curvature of the insole body 100 is based on human anatomy data, which can fill the natural gap between the arch and the insole. The support plate 200 provides rigid structural support, while the arched part of the insole provides dynamic cushioning through flexible materials, balancing stability and comfort.

[0028] Example 2 like Figure 8 and Figure 9 The main difference between this embodiment and Embodiment 1 is that the first connecting part is the rough or hook side of the Velcro, and the second connecting part is the hook or rough side of the Velcro. The unidirectional or bidirectional adhesive properties of the Velcro allow for multi-angle positioning of the support piece: First, people with high arches can shift the support piece towards the inside of the arch to precisely fill gaps; second, people with flat feet can adjust the support piece towards the outside of the arch to enhance lateral support; third, assembly and disassembly can be completed without tools, and users can adjust the position of the support piece in real time according to foot fatigue, avoiding the drawback of traditional fixed structures that "cannot be changed once sewn"; fourth, the connection position between the support piece 200 and the insole body 100 can be easily adjusted, thereby adjusting the support force of the support piece 200.

[0029] Example 3 like Figure 10 , 11 The main difference between this embodiment and Embodiment 1 is that the support plate 200 is connected to the underside of the insole body 100 via a connector 220, which is an elastic rope or spring. During heel strike, the connector 220 compresses and absorbs the ground reaction force, reducing sudden traction on the arch ligaments. In other embodiments, the connector 220 is a hinge. Through the limiting effect of the hinge, the arch of the foot is guided to move within a reasonable range, assisting in exercising the arch muscles (such as the tibialis posterior muscle) and improving its own support. The rotation of the hinge or the deformation of the elastic element can adapt to changes in the arch curvature, reducing local pressure.

[0030] Example 4 This utility model also discloses a shoe that uses an insole with arch support function. Shoes using insoles with arch support function are scientifically designed from the perspectives of human biomechanics, sports health, and wearing experience. Their core advantages are reflected in three dimensions: foot health protection, improved athletic performance, and optimized comfort.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
