Commonly used functional insoles are designed based on the static ergonomic data of the soles of the feet stepping on the horizontal plane. The design points of the insoles are mainly on the part of the forefoot, the inner arch, and the thickening of the heel pad. But modern people have many shoes for daily use, and often wear high-heeled shoes. After the existing insoles are molded, there is generally only one use state, and they cannot be deformed to adapt to various shoes with different shapes; The environment is dominated by hard ground, which causes greater vibration to the feet when walking; and the forefoot pad of the whole insole designed based on static and horizontal sole data is too thin to meet the needs of slowing down the severe force on the forefoot when walking ; and the forefoot pads currently on the market are very easy to shift during walking, which increases the discomfort when walking. Most of the heel pads of existing insoles are symmetrical and single square bulges and thickened, which is not suitable for the actual situation that the outside of the heel is stressed when wearing high-heeled shoes; most of the insoles are integrally formed with one main material, which does not meet the acupoints on the soles and requires different shapes. In reality, its comfort and durability are difficult to satisfy at the same time. The needs of modern people's living conditions and the insufficiency of existing insole functions can easily lead to bone deformation such as hallux valgus, sports injuries such as knee vibration and wear, and low cost performance.

A functional insole, the insole is composed of a surface layer, a thickened layer of the forefoot pad under the surface layer, a silica gel layer of the middle and back palm pad under the surface layer, and a thickness adjustment layer of the middle and back palm pad, wherein the thickness of the middle and back palm pad The adjustment layer is glued under the silicone layer of the mid-heel pad with Velcro.

Among the above, the thickened layer of the front palm pad is made of honeycomb silica gel, and the thickness adjustment layer of the middle and rear palm pad is made of silica gel.

In the above, the surface of the surface layer corresponds to the positions of the stress points of the front palm pad and the rear palm pad respectively provided with thickened layers of latex cushions.

In the above, the gap formed by the surface layer, the thickened layer of the front palm pad, and the silica gel layer of the middle and rear palm pad is filled with a silica gel filling layer.

In the above, the surface layer forms a protrusion corresponding to the position of the inner arch of the foot, and the front and rear edges of the surface layer form convex edges.

Among the above, there are 2-3 layers of ring-shaped silicone fixing layers on the exposed part in front of the thickened layer of the forefoot pad.

The utility model has the beneficial effects: when people wear shoes, it is especially suitable for high-heeled shoes. It can fully and evenly absorb the vibration pressure of the soles of the feet, especially the forefoot soles, and reduce the degree of vibration between the soles of the feet and the ground when they touch the ground, and the resonance between the soles and the musculoskeletal. reduce the impact damage to the human body, effectively prevent and improve heel pain, knee pain and other conditions, and reduce foot fatigue. The adjustable use mode meets the actual needs of people wearing different shoes. Latex and silicone create a rich, comfortable feel and are more durable.

Detailed ways

Referring to Fig. 1 to Fig. 10, the utility model provides a functional insole, the insole is composed of a surface layer 1, a thickening layer 5 of the forefoot pad under the surface layer 1, and a silica gel layer 8 of the middle and rear palm pad under the surface layer 1. and middle and rear palm pad thickness adjustment layer 10, the surface layer 1 is made of latex, the front palm pad thickening layer 5 is made of honeycomb silica gel, the middle and rear palm pad thickness adjustment layer 10 is made of silica gel, and the middle and rear palm pad is made of silica gel. Pad thickness adjustment layer 10 is bonded below the silica gel layer 8 of the middle rear palm pad by Velcro 9 . Latex cushion thickening layers 2 are respectively arranged on the surface of the surface layer corresponding to the stress point positions of the front palm pad and the rear palm pad. The surface layer forms a protrusion 4 corresponding to the position of the inner arch of the foot, and the front and rear edges of the surface layer form a convex edge 3 . The gap formed by the surface layer 1, the thickened layer 5 of the front palm pad, and the silicone layer 8 of the middle and rear palm pad is filled with a silicone filling layer 6, and the exposed part in front of the thickened layer 5 of the front palm pad is fixed with 3 layers of ring-shaped silica gel. Layer 7. Among the above, the surface layer 1, the front palm pad thickening layer 5, the middle and back palm pad silicone layer 8, the silicone filling layer 6 and the ring-shaped silicone fixing layer 7 are bonded together by an adhesive, and the Velcro 9 They are respectively bonded to the middle and rear palm pad silicone layer 8 and the middle and rear palm pad thickness adjustment layer 10 by an adhesive.

The utility model uses integrally formed dense honeycomb-shaped silica gel to thicken the forefoot pad in the insole, and the silica gel with soft texture and obvious shock-absorbing effect forms a solid buffer protection pad that is stressed when walking. The hollow honeycomb structure makes the sole of the foot and the ground form a The non-solid gas buffer belt not only makes the shock absorption effect more obvious, but also reduces the weight of the silicone, making walking more comfortable and light; the honeycomb silicone is fixed with a ring-shaped stack of silicone fixing layers to prevent deformation and increase durability. Use latex that is easy to shape and has a certain degree of elasticity to make the surface layer 1 that fits the ergonomic parameters of the soles of the feet, and add latex cushions to the parts where the soles of the feet are heavily stressed, such as the front of the feet and the heel pads. The cushions of the heels are based on When the human body is walking, the force on the outside of the heel is too large. It is designed to be asymmetrically thickened. The latex cushion thickening layer 2 and the surface layer 1 are integrally formed; the inner arch and the edge of the insole are heightened to support more body The inner arch of the foot is heavy, the latex surface layer 1 slightly harder than silicone and the raised edge make the insole more fixed when the foot is walking; during production, sweat-absorbing and anti-odor cloth can be added to the upper surface of the surface layer 1 as needed layer. Between the middle and rear palm pad thickness adjustment layer 10 and the middle and rear palm pad silicone layer 8, use the Velcro 9 that can be glued and torn to adjust the thickness of the insole. The softness of the main material silicone enables the insole to adapt to different shapes of uppers. The main material of the insole is latex and silica gel. Latex is easy to shape and fit the shape of the sole of the foot. It is elastic but harder than silica gel to meet the functional requirements of the human body that needs to fix the insole to prevent sprains when walking; the softness of silica gel can well reduce the ground, The vibration and resonance pressure generated by the sole, muscles and bones during walking, and its adsorption force prevents the insole from shifting; both have a long service life.

Combined with Figure 1, when walking in shoes, the soles of the feet are pressed on the insole, and the whole sole of the foot is fitted with the latex insole. The feet in motion are fixed by the raised latex edge, and the soles of the feet with local stress are thickened with latex cushions. With the support of the raised inner arch, the heavily stressed forefoot is pressed against the soft honeycomb forefoot pad, which is rebounded by the elastic effect of latex and silicone, so as to reduce the pressure on the sole of the foot and the resonance of the human body, and relieve fatigue. According to different styles of shoes, glue or tear off the Velcro of the mid-heel pad to adjust the thickness of the insole.
