In order to improve the comfort of the user, the side wall 12 is provided with air holes 14, thereby ensuring that the degree of wetness of the foot is kept within a reasonable range. In order to further improve the comfort of the user, the connecting belt 13 may further be provided with air holes 13.

Furthermore, the air holes 14 are round holes, and the inner walls of the round holes are smooth, so that the insole can be effectively prevented from cracking.

As shown in FIG. 5, the insole provided in this embodiment is a raised insole. Of course, in alternative embodiments, the insole may be a raised insole, rather than a raised insole, having a substantially uniform thickness throughout the bottom portion 11.

Example four

As shown in Figs. 6 and 7, the insole of the fourth embodiment is substantially the same as the first embodiment, except that the upper surface 15 of the insole of the second embodiment has a massaging structure and/or a ventilating structure.

As shown in fig. 6, in particular, the surface of the insole contacting the foot has a massage structure, the massage structure comprises salient points 4 or stripes, and the salient points 4 or stripes can rub against the arch of the foot during the walking process of the user, thereby playing a massage role. The stripes can be linear, wave-shaped, zigzag and the like.

Still further, in an alternative embodiment, the bumps 4 or stripes are formed by the pile layer 3. That is, the lengths of the piles are different at the positions of the pile layer 3 facing the arch of the foot, and the long piles form the above-mentioned convex points 4 or stripes. In other alternative embodiments, the bumps 4 or stripes may also be formed from the substrate 1. I.e. the substrate 1 has bumps 4 or stripes at the positions opposite to the arch of the foot, and the lengths of the naps are equal, so that the bumps 4 or stripes of the substrate 1 are still remained after flocking.

As shown in fig. 7, when the insole is used in a high temperature environment, the user's foot is liable to sweat, and in order to further improve the breathability of the insole, it is preferable that the nap layer 3 is formed with a breathable structure, the nap layer 3 includes first and second nap portions 31 and 32 alternately arranged, and the number of the first and second nap portions 31 and 32 is plural. The fluff is adhered to the glue layer 2 through flocking to form a first striped fluff part 31 and a second striped fluff part 32, the length of the fluff of the first striped fluff part 31 is larger than that of the second striped fluff part 32, and the first striped fluff part 31 and the second striped fluff part 32 form a ventilation structure.

Because the length of the floss of the first striped velvet part 31 is longer and can contact the human body, the length of the second striped velvet part 32 is shorter, the second striped velvet part 32 has smaller clearance with the human body or the acting force applied to the second striped velvet part 32 by the human body is smaller, the airflow can pass through the second striped velvet part 32, and therefore, the first striped velvet part 31 and the second striped velvet part 32 form an air-permeable structure together. Meanwhile, the second striped velvet part 32 can prevent the human body from directly contacting the base material 1, so that the comfort level of the insole is ensured.

Preferably, the density of the pile of the first striped pile portion 31 is greater than the density of the pile of the second striped pile portion 32, thereby increasing the breathability of the second striped pile portion 32.

The first striped velvet portion 31 and the second striped velvet portion 32 are in a linear structure, a wavy structure or a sawtooth structure.
