And specifically, the surface layer comprises a mesh-shaped fabric layer 11, the mesh-shaped fabric is connected with the deodorizing fiber layer 13 through elastic fibers 12, wherein the mesh-shaped fabric layer 11 and the elastic fibers 12 are matched to form the hollow elastic structure fabric with a three-dimensional structure.

The surface of the mesh-shaped fabric layer 11 is provided with a mesh structure, which is favorable for air circulation, and in addition, because the mesh-shaped fabric is connected with the deodorizing fiber layer 13 through elastic fibers 12, the mesh-shaped fabric layer 11 and the elastic fibers 12 are matched to form the hollow elastic structure fabric with a three-dimensional structure, and through the hollow elastic structure fabric, on one hand, when no external force is applied, a ventilation space can be kept between the mesh-shaped fabric and the deodorizing fiber layer 13, which is favorable for air circulation and discharge of water vapor and odor, and odor generated by feet can enter the ventilation space through the mesh-shaped fabric layer 11 and be adsorbed by the deodorizing fiber layer 13 to achieve the deodorizing effect; on the other hand, in the process of movement, the foot pressure can make the hollow elastic structure fabric deform, and then the pressure difference is generated in the ventilating space, so that the air flow is accelerated, and the steam and odor are discharged.

The adjusting layer is used for providing support for the foot, and the quality of the support of the insole is one of criteria for judging the quality of the insole, and is different from the existing method that an additionally added support structure is arranged inside the insole body, in this embodiment, the adjusting layer is specially designed, and the support structure is directly formed on the insole body, as shown in fig. 1, specifically:

the adjusting layer can be formed by laminating a plurality of adjusting sub-layers, a plurality of functional areas can be arranged on the adjusting layer, hollow patterns 32 can be arranged at positions on the adjusting sub-layers corresponding to the functional areas, the hollow patterns 32 on the adjusting sub-layers are located on the same functional areas and matched to form a supporting structure for supporting feet, and the supporting structure can be in a shape which is attached to the shapes of the feet after being pressed by the feet.

Wherein the functional zones may include a radicular support zone, a radicular decompression zone, a longitudinal arch support zone, and a transverse arch support zone.

In this embodiment, the adjustment layer is formed by laminating a plurality of adjustment sub-layers 31, and a plurality of functional areas are arranged in the adjustment layer according to the functional areas of the sole of a foot, so as to provide corresponding support performance for the corresponding positions of the sole of the foot. The hollow pattern 32 disposed on the adjustment sublayer 31 is substantially partially hollow on the adjustment sublayer 31 according to a specially designed pattern, so that a hollow part and a solid part are formed on the adjustment sublayer 31. When the plurality of adjustment sub-layers 31 are stacked together to form a support structure, the hollow patterns 32 on two adjacent adjustment sub-layers 31 are staggered or overlapped, specifically, the solid parts on two adjacent adjustment sub-layers 31 are stacked or staggered, so that a plurality of specially designed cavities with different heights and different positions are formed in the functional region. The areas where the solid portions are stacked on top of each other provide better support, while other areas where cavities are present provide correspondingly weaker support depending on the size and number of cavities.

According to the functional area and the mechanics conditions of the foot areas, the supporting force required to be provided by different positions of the foot is different, which can be simply summarized as that the stress point needs to provide larger supporting force, and the position near the stress point provides correspondingly smaller supporting force according to the shape of the foot. Therefore, in the practical application process, the hollow patterns 32 on each of the adjustment sublayers 31 need to be reasonably designed according to the functional areas and the mechanical conditions of the foot areas, so that the support structure formed on the adjustment layer can provide the foot with a three-dimensional stress surface with the stress point as the center according to the functional area where the support structure is located, and the support structure forms a shape fitting the foot shape after bearing the foot pressure. Therefore, on the one hand, the stress surface adaptive to the mechanical condition of the foot can be provided, the foot is supported well, on the other hand, the influence on the foot is small, the foot cannot be pressed to deform, the foot health is facilitated, and the wearing comfort is good.

In addition, the hollow patterns 32 on the adjustment sub-layer 31 may be one hollow pattern 32 corresponding to each functional region, or one hollow pattern 32 corresponding to one or more functional regions.

In particular, the supporting structure may be formed by laminating and matching the hollow patterns 32 on the plurality of adjustment sub-layers 31 in the longitudinal direction. The adjacent adjusting sub-layers 31 are bonded together through glue, the bonding area is large, the integrity is strong, the upper direction and the lower direction of the supporting structure on the adjusting sub-layers 31 are respectively provided with the buffer layer and the supporting layer 4, the integrity of the body is further enhanced, the degumming condition can not occur in the using process, and the durability is good.

The support layer 4 may be made of high-density EVA (ethylene and its copolymer) for maintaining the shape of the front part of the insole body without curling and providing a supporting force to the adjustment layer to maintain the overall shape of the insole.

The anti-slip layer 5 is used for increasing the friction force between the insole body and the inner bottom surface of the shoe, and the insole body is prevented from sliding in the horizontal direction under the influence of feet in the wearing process, so that the wearing comfort is influenced. In addition, in order to further improve the anti-skid performance of the supporting insole, the bottom surface of the anti-skid layer 5 can be provided with anti-skid stripes.
