Specifically, in the embodiment of the present application, the shape of the first groove is the same as that of the first energy absorbing pad 30, and the depth of the first groove is slightly smaller than the thickness of the first energy absorbing pad 30. Like this, when the installation, the groove edge of first recess can play limiting displacement to first energy absorbing gasket 30, avoids the condition that first energy absorbing gasket 30 took place to remove in the motion process, can guarantee the stability that first energy absorbing gasket 30 and buffer layer 20 are connected.

Optionally, the second positioning portion 202 includes a through hole, and the antibacterial breathable layer 50 is embedded in the through hole. The through hole penetrates the shock absorbing layer 20.

Like this, with antibiotic ventilative layer 50 embedding to the through-hole in, can reduce the whole thickness after antibiotic ventilative layer 50 is connected with buffer layer 20, can reduce the whole thickness of shoe-pad 1 promptly, improve the travelling comfort of human foot, foot. Simultaneously, the lateral wall of through-hole can carry on spacingly to antibiotic ventilative layer 50, avoids antibiotic ventilative layer 50 to take place the displacement to can also improve antibiotic ventilative layer 50's installation effectiveness.

Alternatively, as shown in fig. 1 and 2, the entire shape of the through-holes may be a shaped hole, and the antibacterial breathable layer 50 may have the same shape as the shaped hole. Thus, the overall appearance of the insole 1 can be improved, and the user experience can be improved.

Further, referring to fig. 1, the antibacterial breathable layer 50 has a third positioning portion 501 on a side away from the shock absorption layer 20, and the second energy-absorbing pad 40 is mounted on the third positioning portion 501.

Specifically, the third positioning portion 501 may be formed in the same manner or in a different manner from the first positioning portion 201 or the second positioning portion 202. The third positioning portion 501 may be a second groove concavely formed from a side of the antibacterial ventilation layer 50 facing away from the shock-absorbing layer 20.

Alternatively, the shape of the second recess may be the same as the shape of the second energy-absorbing pad 40, and the depth of the second recess may be slightly less than the thickness of the second energy-absorbing pad 40.

In some specific examples, the first energy absorbing pad 30 and the second energy absorbing pad 40 may have a thickness of 2.0mm to 2.5 mm. It should be noted that the numerical values and numerical ranges referred to in this application are approximate values, and there may be some error due to the manufacturing process, and the error may be considered to be negligible by those skilled in the art.

It is understood that the thickness of shock absorber layer 20 may also be in the range of 2.0mm to 2.5 mm.

By providing the third positioning portion 501, the second energy-absorbing pad 40 can be conveniently mounted and connected.

In particular implementations, adhesive layers (e.g., double-sided adhesive or the aforementioned polyurethane adhesive) may be patterned on the inner walls of the first and second grooves, respectively; then, the first energy-absorbing gasket 30 is installed in the first groove, the second energy-absorbing gasket is installed in the second groove, the first energy-absorbing gasket 30 is stably connected with the shock absorption layer 20 in a pressing mode, and the second energy-absorbing gasket 40 is stably connected with the antibacterial breathable layer 50.
