Referring to fig. 1, 2, 5 to 7, the present invention provides an insole 100, which includes an insole body 10, wherein the insole body 10 includes a buffering layer 20 and an impact-resistant layer 30 covering the buffering layer 20, a damping coefficient of a material of the buffering layer 20 is not less than 0.6, and a density range of the material of the buffering layer 20 is 0.3g/cm³-0.5g/cm³。

The insole 100 provided by the utility model has the advantages that the buffering layer body 20 is used as the inner layer, the anti-impact layer body 30 is coated outside the buffering layer body 20, so that the insole 100 has stronger buffering capacity and anti-impact capacity, meanwhile, the damping coefficient of the material of the buffering layer body 20 is set to be not less than 0.7, and the material density range of the buffering layer body 20 is set to be 0.3g/cm³-0.5g/cm³At this time, the buffering layer body 20 has a better buffering effect, which is beneficial to the impact and shock on the footThe motion is reduced to a minimum.

The specific structures of the buffer layer 20 and the impact-resistant layer 30 coated on the buffer layer 20 may be various structures of complete coating and partial coating. As shown in fig. 5, the impact-resistant layer 30 is completely covered outside the buffer layer 20, and the buffer layer 20 is present inside the impact-resistant layer 30 as an inner core. When the foot pedal is used, the buffering layer body 20 of the inner core is used for buffering the foot pedal action, and the impact-resistant layer body 30 of the outer layer is used for offsetting the impact force generated when the foot pedal action. As shown in fig. 6, in a case of partial coating, the impact-resistant layer 30 is coated along the plane periphery of the buffer layer 20, and the periphery of the buffer layer 20 is completely coated. When the foot massage device is used, the inner buffering layer body 20 is used for buffering the foot treading action, and the impact-resistant layer body 30 on the periphery of the buffering layer body 20 is used for supporting the foot to offset the impact force generated when the foot is treaded. As shown in fig. 7, another case of partial coating is that the impact-resistant layer 30 is disposed on two opposite sides of the buffer layer 20 and sandwiches the buffer layer 20. When the foot pedal buffer is used, the inner buffer layer 20 is used for buffering the foot stepping action, and the impact-resistant layer 30 on the two opposite sides of the buffer layer 20 is used for offsetting the impact force generated when the foot is stepped.

Specifically, insole body 10 is used for laying in the shoes of high-heeled shoes, and when the user walks, insole 100 can provide abundant buffering in order to reduce impact and vibrations that the foot received when stepping on high-heeled shoes walking on ground on the foot pad, in order to reduce the injury that the foot received when wearing high-heeled shoes. Wherein, the material damping coefficient of the buffer layer body 20 and the material density of the buffer layer body 20 are quantitatively tested to obtain the buffer layer body 20 with better buffering effect. According to the experiment, the EN 1621-12012 standard is referred, and the impact force is adopted to indirectly obtain the buffering effect of the material, namely the smaller the impact force is, the better the buffering effect of the material is represented, the smaller the impact force passing through the material is, and the more effective the protection on feet is. Specific experimental data are as follows.

According to the table shown in the above, the damping coefficient is 0.7, 0.8 and 0.9, and the material density is 0.3g/cm³、0.4g/cm³And 0.5g/cm³The magnitude of the penetrating impact of the material. It will be appreciated that the smaller the value of the penetration impact force of the material, the better the cushioning effect of the material, i.e. the smaller the impact force acting on the foot through the material.

It can be seen that, with the damping coefficient kept constant, the greater the value of the material density, the smaller the penetration impact force of the material, i.e. the better the cushioning effect of the material. For example, at a damping coefficient of 0.7, a material density of 0.3g/cm is selected³、0.4g/cm³And 0.5g/cm³From the above results, when the density of the material is 0.5g/cm³The penetration impact force of the material is 25KN, and the penetration impact force is the smallest among three material density values, namely, the larger the material density value is, the better the buffering effect of the material is.

Meanwhile, under the condition that the numerical value of the material density is kept unchanged, when the damping coefficient of the material is larger, the penetrating impact force of the material is smaller, namely the buffering effect of the material is better. For example, the density of the material in the buffer layer body 20 is 0.5g/cm³And selecting the damping coefficients of 0.7, 0.8 and 0.9 for test comparison to obtain that when the damping coefficient is 0.9, the penetration impact force of the material is 20N, and the penetration force is the smallest among the three damping coefficients, namely, the larger the damping coefficient of the material is, the better the buffering effect of the material is.

In summary, the cushioning effect of the cushioning layer body 20 is affected by the damping coefficient of the material and the density of the material, and the greater the damping coefficient of the material and the greater the density of the material, the smaller the penetration impact force of the material, i.e. the best cushioning effect of the material. Considering the factors of cost, manufacturing process and the like, the damping coefficient of the material is set to be not less than 0.7, and the density of the material is set to be in a range of 0.3g/cm³-0.5g/cm³In this case, the buffer layer body 20 has an excellent buffer effect, and the cost and the manufacturing difficulty are both within a controllable range.
