In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Referring to fig. 1 and to fig. 2, according to an aspect of the present invention, there is provided an insole, wherein the insole comprises an EVA layer 4 and a PET (Polyethylene terephthalate) layer 3 stacked on the EVA layer 4, the EVA layer 4 comprises a sole portion 41, an arch portion 42 and a heel portion 43 connected in sequence, and the PET layer 3 is attached to the arch portion 42 and the heel portion 43.

The technical scheme of the utility model, because the shoe-pad that provides includes EVA layer 4 and folds the PET layer 3 of establishing on EVA layer 4, EVA layer 4 is including the sole portion 41, arch of foot portion 42 and heel portion 43 that connect gradually, and PET layer 3 laminates with arch of foot portion 42 and heel portion 43. Compare traditional EVA shoe-pad, one deck PET layer 3 has been increased on the arch of foot portion 42 and the heel portion 43 on EVA layer 4, PET layer 3 is because toughness is strong and have antifriction and fatigue resistance, heel bone and arch of foot support part can be stabilized, so that the resilience and the buffering of whole arch of foot curvature all can strengthen, reduce the impact force that the low limbs joint bore, strengthen the motion performance and improve the flexibility of foot, EVA layer 4 laminates with PET layer 3 simultaneously, can improve PET layer 3's stability and make the foot obtain bigger cushioning effect.

Further, the arch portion 42 includes a first extension portion 421 and a second extension portion 422 connected to the first extension portion 421, the first extension portion 421 is raised from the sole portion 41 to a plane away from the sole portion 41, the second extension portion 422 is raised from the heel portion 43 to a plane away from the heel portion 43, and the first extension portion 421 and the second extension portion 422 form a convex structure for fitting with an arch area of the foot. The shape of the arch part 42 is consistent with the shape of a normal arch, so that the insole can directly support the arch area of the foot, the strong supporting effect of the insole on the arch area can be obtained when the arch area is stressed, and the damage of foot joints is avoided.

Specifically, the height difference between the joint of the first extension 421 and the second extension 422 and the sole portion 41 is greater than or equal to 10 mm. In the present invention, the height difference may be 20 mm, and this height difference may be selected appropriately according to specific conditions.

In addition, heel portion 43 is recessed from the outer edge toward the center for full conformity with the heel area of the foot. Heel 43 can thus achieve 360 ° fit to the heel area of the foot, perfectly stabilize the heel area and protect the joints in the heel area from impact damage.

Referring to fig. 1, in one embodiment, the insole further comprises an esomeprazole layer 2 laminated on the PET layer 3, the esomeprazole layer 2 being attached to the PET layer 3 and the sole portion 41. The Ousolai layer 2 is made of Polyurethane (PU) foam, has the advantages of air permeability, sweat absorption, deodorization, mildew prevention, bacteriostasis, portability, wear resistance and good buffering performance, and particularly has soft and air permeability, so that the Ousolai layer 2 is overlapped on the PET layer 3, and discomfort caused by high hardness of the EVA layer 4 and the PET layer 3 can be avoided.

Further, a plurality of grooves (not shown) are spaced on the EVA layer 4, and the grooves are V-shaped. The groove opening diameter of the ball and

heel portions

41, 43 is less than the groove opening diameter of the arch portion 42, as the ball and

heel portions

41, 43 are required to provide the primary support for the foot. In one embodiment, the PET layer 3 and the oslely layer 2, which are correspondingly attached to the EVA layer 4, are provided with a plurality of protrusions which are matched with the grooves on the EVA layer 4, and the protrusions and the grooves are engaged with each other to increase the cushioning, energy absorption and shock absorption effects of the insole on the stress of the foot, thereby improving the comfort of the foot.

Referring to fig. 2 and 4, in one embodiment, the surface area of the PET layer 3 is less than the surface area of the arch 42 and heel 43 portions, the PET layer 3 being disposed within the cavity enclosed by the EVA layer 4 and the esomeprazole layer 2. PET layer 3 is plastic products, is difficult for laminating with EVA layer 4 and the 3 layers of the 3-layer pairs of Ouchuolai, in order to guarantee the life-span of shoe-pad, sets up PET layer 3 in the cavity that EVA layer 4 and the 2 layers of the Ouchuolai enclose to walk the line to PET layer 3 and EVA layer 4 and sew up, guarantee the firm and stability of shoe-pad.

Referring to fig. 3, in another embodiment, the EVA layer 4, the PET layer 3 and the esomeprazole layer 2 have vent holes 6 formed therein. The plurality of air holes 6 are formed on the EVA layer 4, the PET layer 3 and the Oucholai layer 2 at intervals, so that the ventilation of the sole can be realized, and the foot is not easy to sweat, foul and stuffy.

Furthermore, the insole also comprises a weaved cloth layer 1 which is overlapped on the Oesol layer 2. The knitted fabric layer 1 is 100% terylene weft knitting mesh cloth (polyester fiber), the knitted fabric layer 1 has good wear resistance and can absorb sweat and deodorize, and the most important function is to enhance the friction force and air permeability of the sole and the insole.

Meanwhile, the insole also comprises a non-woven fabric layer 5 which is overlapped at the bottom of the EVA layer 4, and grooves or grains are arranged on the non-woven fabric layer 5. The non-woven fabric layer 5 has the functions of moisture resistance, ventilation, light weight, antibiosis and the like. The grooves or lines are arranged on the non-woven fabric layer 5 to enhance the friction force of the insole.

Referring to fig. 4, in one embodiment, the insole may have a thickness of 4 to 8 mm. More specifically, the thickness of the esomeprazole layer 2 may be 3 mm, the thickness of the PET layer 3 may be 1.5 mm, and the thickness of the EVA layer 4 may be 1 mm, and may reach 5 mm after passing through the lamination process. The invisible height-increasing purpose can be achieved by combining the height difference of the arch part 42.

In addition, the utility model also provides a shoes (not shown), wherein, the shoes include vamp, sole and above shoe-pad. Because this well shoes have included the utility model provides an insole, so shoes also possess the whole advantages of the utility model provides an insole.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
