Description

Technical Field

[0001] The utility model relates to the technical field of insoles, and specifically designs a shock-absorbing and supporting insole. Background Art

[0002] Insoles are daily necessities that can provide comfort to the wearer. Existing insoles are mostly made of rubber material, which is elastic to improve the comfort of wearing shoes. However, this structure has a single function. When people walk, the soles of the feet are subjected to different pressures. Using an insole with a single structure will result in insufficient comfort and support for the soles of the feet.

[0003] Existing technology (CN219982265U) discloses a functional insole with shock absorption, moisture removal, and breathability. The insole features a high-elastic forefoot pad, an arch support and stabilization plate, and a cushioning and shock-absorbing heel pad at the bottom. However, the arch support and stabilization plate is an integrated structure with uniform hardness. Using a softer support plate results in insufficient support and strength. Using a harder support plate results in insufficient foot comfort, which can increase foot fatigue after long walks. Therefore, it is necessary to improve foot comfort while ensuring adequate support. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] A shock-absorbing support insole comprises an insole body, wherein the insole body 3 comprises a forefoot portion, an arch portion and a rearfoot portion, a shock-absorbing layer 2 and an anti-slip layer 1 are sequentially arranged on the top of the sole body 3, a first groove portion 31 is provided at the forefoot portion of the bottom of the insole body 3, the first groove portion 31 is butterfly-shaped, and is fitted with a forefoot shock-absorbing pad 4 to buffer forefoot pressure; a second groove portion 32 is provided at the arch portion and the rearfoot portion of the bottom of the insole body 3, and is fitted with a first support sheet 6 to improve the strength of the insole, provide strong and comfortable support for the arch and heel area, reduce the pressure on the plantar fascia, and have a certain anti-torsion function to prevent external force from twisting Injury; the back of the foot of the first support piece 6 is provided with an opening, which is "U"-shaped, and the opening is sleeved with the heel cushioning pad 5, which absorbs the impact of the heel and has the function of cushioning and energy absorption; the inner side of the arch of the first support piece 6 is provided with a third groove 61, and is sleeved with the second support piece 7 to provide support for the inner side of the arch of the foot; the hardness of the second support piece 7 is greater than that of the first support piece 6, and the first support piece 6 is softer than the second support piece 7, and has better soft elasticity, while ensuring support, increasing the comfort of the sole of the foot; the second support piece 7 is harder to ensure the support strength, correct flat feet, and prevent sprains during exercise.

[0021] The first support sheet 6 is a one-piece TPU member with a hardness of 84-88 Shore A, while the second support sheet 7 is a one-piece TPU member with a hardness of 90-95 Shore A. TPU offers high wear resistance, a wide hardness range, high mechanical strength, excellent processing properties, and good cold resistance, maintaining its elasticity even at -40°C.

[0022] The second support piece 7 is half-moon shaped, adapting to the shape of the arch of the foot and providing stable support; and a plurality of parallel strip-shaped hollow openings are provided to reduce the weight of the insole, making it more comfortable to wear and having a good shape-keeping effect, which can support and protect the human arch of the foot and prevent sprains.

[0023] The insole body 3 is made of Osole material, a novel material. Its open-pore structure creates an internal air circulation system, allowing for smoother airflow and achieving excellent breathability. Whether in hot summer or humid environments, the Osole insole effectively keeps feet dry and comfortable, preventing bacterial growth. In addition to its breathability, Osole material also boasts excellent resilience. With a resilience of over 42%, it provides long-lasting comfort and reduces foot fatigue. As the main material, it provides support tailored to the foot's shape.

[0024] The shock-absorbing layer 2, forefoot cushion 4, and heel cushion 5 are made of artificial cartilage biomimetic material (ACF), which converts impact energy into heat, effectively absorbing 90% of impact force, protecting the feet, knees, and body from impact damage. The ACF material offers over 10 times the support strength, withstands compression for 100,000 impact cycles, and resists fatigue. While conventional materials typically absorb energy through compression deformation, ACF material instantly converts impact energy into heat through energy conversion. Therefore, a 3mm ACF material offers better energy absorption than 10mm EVA, rubber, latex, or polyurethane (PU) materials. When walking, using conventional insoles made of anti-slip fabric, polyurethane (PU), and a Hypolai pad, impact forces of 1 to 5 times one's body weight are transmitted upwards, severely impacting and injuring the knees. However, using the insoles provided by the present invention, the majority of the impact force is absorbed by the ACF at the sole of the foot, preventing it from being transmitted upwards, providing maximum protection from knee injury.

[0025] The bottoms of the forefoot cushioning pad 4 and the heel cushioning pad 5 are provided with a hexagonal mesh pattern to prevent the insoles from sliding.

[0026] The anti-slip layer 1 is an anti-slip fabric with breathable, anti-slip, wear-resistant and sweat-absorbing functions, specifically a microfiber fabric.

[0027] In another embodiment, a teardrop-shaped protrusion 9 is provided in the middle of the upper surface of the shock-absorbing support insole to achieve the effect of massaging the sole of the foot.

[0028] The insole provided by the utility model has a U-shaped heel cup design, which fits firmly and wraps the heel.

[0029] The insole provided by the utility model includes an anti-slip layer 1, a shock-absorbing layer 2, an insole body 3, a forefoot shock-absorbing pad 4, a heel shock-absorbing pad 5, a first support sheet 6 and a second support sheet 7, and the various components are connected into one by gluing.

[0030] The utility model provides a first groove portion at the forefoot portion of the bottom of the insole, and fits the forefoot shock-absorbing pad; a second groove portion is provided at the arch portion and the rearfoot portion of the bottom of the insole, and fits the first support piece; the heel shock-absorbing pad is embedded in the rear foot portion of the first support piece, which not only absorbs impact force and achieves a shock-absorbing effect, but also improves the strength of the insole and provides stable support; a third groove portion is provided on the inner side of the arch of the first support piece, and fits the second support piece, and the hardness of the second support piece is greater than that of the first support piece. The first support piece is softer than the second support piece and has better soft elasticity, which increases the comfort of the sole of the foot while ensuring support; the second support piece is harder to ensure the support strength, prevent sprains during exercise, and correct flat feet.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
