Description

Technical Field

[0001] This utility model relates to the field of shoe insole technology, specifically to a breathable and shock-absorbing shoe insole. Background Technology

[0002] Insoles are padding components placed inside shoes that come into direct contact with the soles of the feet. Their core functions are to improve wearing comfort, protect foot health, and provide targeted support according to different needs. To enhance comfort, shock-absorbing insoles have emerged on the market. These are functional insoles designed based on ergonomic and biomechanical principles. They primarily use elastic materials as a cushioning layer to absorb and disperse the impact force on the feet during walking or exercise, preventing excessive pressure on any particular area.

[0003] However, existing shock-absorbing insoles have a relatively simple structure, poor cushioning effect, and poor wearing comfort. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a breathable and shock-absorbing insole. When the forefoot rests on the curved protrusions in the forefoot area, these protrusions massage the forefoot. When the forefoot presses down, the gas inside the cushioning cavity is expelled through the vents. The combination of cushioning from the cushioning pad and the venting of the cushioning cavity enhances the insole's shock absorption. When the foot is lifted while walking, the vents dynamically release air, improving air circulation and breathability within the shoe, effectively reducing stuffiness and further enhancing the insole's comfort.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a breathable and shock-absorbing insole, including a forefoot area and a heel area, and further including a foot support area and an arch area disposed between the forefoot area and the heel area, and an edge shaping area disposed at the edge of the heel area. The forefoot area is provided with a plurality of arc-shaped protrusions, and a shock-absorbing cavity is formed between the arc-shaped protrusions and the upper surface of the sole. Each arc-shaped protrusion is provided with a vent hole communicating with the shock-absorbing cavity.

[0006] The foot support area is located on the outer side of the sole of the foot, and the front end of the foot support area is connected to the forefoot area, the rear end of the foot support area is connected to the heel area, and the foot support area gradually thickens from the edge to the center.

[0007] The arch area is located on the inside of the sole of the foot. The arch area is crescent-shaped and fits the arch of the foot. The front end of the arch area is connected to the side of the foot support area, and the rear end of the arch area is connected to the heel area. The arch area gradually thickens from the edge to the center.

[0008] The insole is formed by pressing and shaping a cushioning layer and a surface layer together.

[0009] The number of the arc-shaped bosses is 10-15, the diameter of the arc-shaped bosses is 5-15mm, the height of the arc-shaped bosses is 3-7mm, and the diameter of the vent hole is 1-3mm.

[0010] The thickness of the forefoot area is 2-6mm, the thickness of the arch area is 1-5mm, the thickness of the heel area is 4-8mm, the thickness of the sole support area is 2-5mm, and the width of the edge shaping area is 0.5-1.5mm.

[0011] The number of arc-shaped bosses is 13, the diameter of the arc-shaped bosses is 10mm, the height of the arc-shaped bosses is 5.5mm, and the diameter of the vent hole is 2mm.

[0012] The thickness of the shock-absorbing sponge in the forefoot area is 4mm, the thickness of the arch area is 5mm, the thickness of the sole support area is 3mm, the thickness of the heel area is 6mm, and the width of the edge shaping area is 1mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the forefoot is placed on the curved protrusions in the forefoot area, several curved protrusions massage the forefoot. When the forefoot is pressed down, the gas in the cushioning cavity is discharged through the exhaust hole. Through the combination of the cushioning pad and the cushioning when the cushioning cavity is discharged, the cushioning effect of the insole is better. When the foot is lifted and walking, the exhaust hole can dynamically discharge air, making the air circulation in the shoe more breathable, effectively reducing the stuffiness of the sole, and further improving the comfort of the insole.

[0015] (2) The arch area is a crescent shape that fits the arch of the foot. The thickness of the arch area is different from that of the heel area, the foot support area, and the forefoot area. Through the differentiated design of the thickness of different areas, the pressure on different areas is dispersed, thereby relieving foot fatigue. Especially for people with flat feet, it can significantly improve the discomfort symptoms when walking or standing.

[0016] (3) The foot support area is made of a material with moderate hardness and elasticity, which can evenly distribute the pressure on the sole of the foot. During walking or standing, it can effectively reduce the local pressure concentration on the sole of the foot, making the force on various parts of the sole more balanced. This uniform support helps maintain the normal physiological structure and function of the foot, reduces foot pain and fatigue caused by uneven pressure, and further improves the overall comfort and practicality of the insole.

[0023] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] See Figures 1-5 A breathable and shock-absorbing insole includes a forefoot area 1 and a heel area 2, as well as a foot support area 3 and an arch area 4 disposed between the forefoot area 1 and the heel area 2, and an edge shaping area 5 disposed at the edge of the heel area 2. The forefoot area 1 is provided with a plurality of arc-shaped protrusions 11 arranged in an array, and a shock-absorbing cavity 12 is formed between the arc-shaped protrusions 11 and the upper surface of the sole. Each arc-shaped protrusion 11 is provided with a ventilation hole 13 that communicates with the shock-absorbing cavity 12.

[0025] The plantar support area 3 is located on the outer side of the sole of the foot, and the front end of the plantar support area 3 is connected to the forefoot area 1, and the rear end of the plantar support area 3 is connected to the heel area 2. The plantar support area 3 gradually thickens from the edge to the center.

[0026] The arch area 4 is located on the inside of the sole of the foot. The arch area 4 is crescent-shaped and fits the arch of the foot. The front end of the arch area 4 is connected to the side of the sole support area 3, and the rear end of the arch area 4 is connected to the heel area 2. The arch area 4 gradually thickens from the edge to the center.

[0027] The insole is made by pressing and shaping a cushioning layer 6 and an outer layer 7 together.

[0028] The number of curved bosses 11 is 10-15, the diameter of the curved bosses 11 is 5-15mm, the height of the curved bosses 11 is 3-7mm, and the diameter of the vent hole 13 is 1-3mm.

[0029] The thickness of the forefoot area 1 is 2-6mm, the thickness of the arch area 4 is 1-5mm, the thickness of the heel area 2 is 4-8mm, the thickness of the sole support area 3 is 2-5mm, and the width of the edge shaping area 5 is 0.5-1.5mm.

[0030] There are 13 curved bosses 11, each with a diameter of 10mm and a height of 5.5mm. The diameter of the vent hole 13 is 2mm.

[0031] The thickness of the shock-absorbing sponge in the forefoot area 1 is 4mm, the thickness of the arch area 4 is 5mm, the thickness of the sole support area 3 is 3mm, the thickness of the heel area 2 is 6mm, and the width of the edge shaping area 5 is 1mm.

[0032] The specific working process and principle of this utility model:

[0033] When the insole is placed inside the shoe, the bottom of the insole is combined with the inside of the sole, forming a cushioning cavity 12 between the curved protrusion 11 and the upper surface of the sole. When the forefoot steps on the curved protrusion 11 in the forefoot area 1, the several curved protrusions 11 massage the forefoot. When the forefoot presses down, the air in the cushioning cavity 12 is discharged through the vent 13. The cushioning effect of the insole is improved by the combination of the cushioning pad and the cushioning when the cushioning cavity 12 is discharged. When the foot is lifted and walking, the vent 13 can dynamically discharge air, making the air circulation inside the shoe more breathable, effectively reducing the stuffiness of the sole, and further improving the comfort of the insole.

[0034] The arch area 4 is a crescent shape that fits the arch of the foot. The thickness of the arch area 4 is different from that of the heel area 2, the foot support area 3, and the forefoot area 1. Through the differentiated design of the thickness of different areas, the pressure on the arch of the foot is distributed, thereby relieving foot fatigue. Especially for people with flat feet, it can significantly improve the discomfort symptoms when walking or standing.

[0035] The foot support zone 3 uses a 3mm thick material with moderate hardness and elasticity, which can evenly distribute the pressure on the sole of the foot. During walking or standing, it can effectively reduce local pressure concentration on the sole of the foot, making the force distributed more evenly across all parts of the foot. This uniform support helps maintain the normal physiological structure and function of the foot, reduces foot pain and fatigue caused by uneven pressure, and further improves the overall comfort and practicality of the insole.

[0036] The heel area 2 features a 6mm thick gradient cushioning layer. This layer utilizes special materials and structural design to achieve an impact absorption rate of ≥70%. During walking or exercise, the heel is the first to contact the ground. This gradient cushioning layer can quickly absorb the impact force from the ground reaction force, effectively reducing the pressure on the heel and minimizing the risk of injury to the heel and leg joints caused by vibration.

[0037] The edge shaping area 5 has an ultra-narrow width of 1mm. The cushioning layer 6 and the surface layer 7 are pressed together using a hot-press molding process. This effectively prevents the insole from shifting inside the shoe, ensuring that the insole always stays in the correct position, improving the fit between the insole and the shoe and the foot, and bringing users a more stable and comfortable wearing experience.

[0038] The insole is manufactured using a thermoforming process. During this process, precise control of parameters such as temperature, pressure, and time ensures that all parts of the insole are tightly bonded together as a single unit. Simultaneously, a microporous interconnection structure between the raised points and the base allows for air circulation. This microporous interconnection structure provides a channel for airflow while maintaining the overall strength of the insole, further optimizing the performance of the dynamic exhaust and pressure reduction system.

[0039] Regarding arch support: Experimental tests show that the 3mm thick material in the arch area 4 of the insole can effectively distribute 60% of the arch pressure. For people with flat feet, this arch support can significantly improve the pressure distribution on the foot, alleviate foot fatigue caused by insufficient arch support, and make walking and standing easier and more comfortable.

[0040] Regarding shock absorption performance: The 6mm thick cushioning layer in the heel area 2 provides excellent shock absorption, effectively absorbing the impact energy from ground reaction forces during walking or exercise. By reducing the impact force on the soles of the feet, it effectively reduces the risk of foot diseases such as plantar fasciitis, providing reliable protection for foot health.

[0041] Regarding the distribution of plantar pressure: The 3mm thickness of the plantar support zone 3 can effectively distribute plantar pressure, reduce local pressure concentration, reduce discomfort caused by uneven pressure, and improve comfort during long-term walking or standing.

[0042] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
