[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In this application, the terms "comprises" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0030] See also Figure 1 to Figure 5 An embodiment of the present application provides an insole 100, wherein the insole 100 has the following Figure 1 The insole body 110 is provided in the length direction and the width direction (the length direction is the X direction, and the width direction is the Y direction) as shown in the figure. The insole body 110 includes an elastic layer 111 and a wear-resistant layer 112 bonded to each other. Specifically, the wear-resistant layer 112 is located on the upper surface of the elastic layer 111 for contacting the sole of the foot. In this embodiment, the wear-resistant layer 112 may be made of Jiaji cloth, which has good air permeability and waterproofness, and can make the insole 100 have antibacterial and deodorizing effects.

[0031] The insole body 110 is divided into a forefoot area 120, a midfoot area 130 and a heel area 140 in the length direction. In order to relieve foot fatigue, the forefoot area 120 of the present application is a flat sheet structure with uniform thickness. The thickness of the insole body 110 gradually increases from the midfoot area 130 to the heel area 140, and the upper surface of the heel area 140 has a depression 141 that wraps the heel (the depression 141 has the function of stabilizing the heel). The various structures of the insole body 110 fit the physiological curve of the foot, so that the pressure on the foot is reasonably dispersed when walking or standing, and the fatigue of the foot is relieved.

[0032] Further, such as Figure 3 As shown, the arch of the foot is divided into an inner arch 300 and an outer arch 310. In order to make the insole 100 better fit the arch of the foot, the two sides of the sole area 130 have a first protrusion 131 and a second protrusion 132 that fit the arch of the foot, that is, the first protrusion 131 fits the inner arch 300 (for supporting the inner arch 300), and the second protrusion fits the outer arch 310 (to maintain outer balance and prevent sprains). Since the inner arch 300 is higher than the outer arch 310, the thickness of the first protrusion 131 is greater than the thickness of the second protrusion 132.

[0033] In this embodiment, the maximum thickness of the insole body 110 is 1.5 cm to 3.0 cm, and the elastic layer 111 is made of PU material.

[0034] Taking health care and further fatigue relief into consideration, the sole area 130 is provided with a third protrusion 133 aimed at the Yongquan point on the sole of the foot. When walking or standing, the third protrusion 133 can massage the Yongquan point to promote blood circulation in the lower limbs and relieve muscle tension.

[0035] In order to increase comfort, the third protrusion 133 and the sole 200 body are integrally formed, and the third protrusion 133 can be deformed well when walking or standing to reduce discomfort of the foot.

[0036] See also Figure 5 In order to reduce the impact force when the heel touches the ground, the insole 100 of the present application further includes a cushion pad 150 disposed in the heel area 140, and a positioning groove 160 is disposed on the lower surface of the insole body 110 to cooperate with the cushion pad 150. The shape of the cushion pad 150 can be set according to requirements, such as a circular or oval shape, etc., and the present application does not make special requirements. When the cushion pad 150 is installed in the positioning groove 160, the cushion pad 150 is flush with the lower surface of the insole body 110.

[0037] The present application also provides a shoe including a sole 200 and an upper 210, which also includes an insole stacked on the sole 200, and the insole structure refers to any of the above embodiments.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0039] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
