[0019] Figure 2 It is a front view of the utility model.

[0020] In the figure, the reference signs are as follows: insole body 11, fabric 12, soft material module 13, hard support member 14, deformation opening 141, shock-absorbing glue module 15, gravity guide groove 16. DETAILED DESCRIPTION

[0021] The specific implementation manner of the utility model embodiment will be described below with reference to the drawings.

[0022] Reference Figure 1 and Figure 2The utility model provides a shoe -pad with the function of correction, including shoe -pad body 10, the edge of shoe -pad body 10's arch of foot to heel position extends upwards and forms cup structure, the bottom surface of shoe -pad body 10 is equipped with gravity guide line groove 16, gravity guide line groove 16 is located in the bottom surface middle part of shoe -pad body 10, and by the front metatarsal extends to the rear heel, gravity guide line groove 16 is matched with the shape of left and right feet, and is arc line groove structure, the utility model discloses the design of gravity guide line groove 16, after the foot pressure, pressure concentrates to gravity guide line groove 16, and the both sides of shoe -pad will produce deformation due to the reason of pressure concentration, and cup structure is matched with, and the arch of foot and heel position form the package, restraint, can improve the function to the foot eversion problem.

[0023] Specifically, referring to Figure 1 And Figure 2 , shoe -pad body 10 is made of supercritical high elastic material or EVA soft high elastic material, and in the embodiment, preferably supercritical high elastic material has very preferred high elasticity, especially when the front metatarsal force, can improve good high elasticity, reduce the burden for walking, running. The top surface of shoe -pad body 10 is paved with skin-friendly antibacterial fabric 12, and the skin-friendly antibacterial fabric 12 provides excellent comfort and hygiene for the contact between the shoe -pad and the foot palm skin.

[0024] In the embodiment, the supercritical high elastic material uses pure nitrogen physical foaming, compared with the ammonia, carbon monoxide and carbon dioxide generated by high-temperature decomposition of chemical foaming, and the decomposition will generate more residues, resulting in product odor, need to be parked for a long time to volatilize and other problems. The utility model uses pure nitrogen physical foaming, without any residues, and the product has no odor, and the nitrogen emission does not affect the environment, which has environmental protection significance. The polydodecanolactam and ethylene vinyl acetate composite modified material used for foaming has the advantages of finer foaming pores, better elasticity and durability.

[0025] Referring to Figure 2 , the bottom surface of shoe -pad body 10 is inlaid with a soft material module 13 at the front metatarsal position, the soft material module 13 is made of EVA soft high elastic material or supercritical high elastic material, which thickens the front metatarsal position and reduces the impact force of the ground on the front metatarsal position when the front metatarsal position is forced. In the embodiment, EVA soft high elastic material is preferred.

[0026] Referring to Figure 2, the bottom surface of the insole body 10 is provided with a hard support 14 at the arch to heel position, which is preferably a hard EVA support or a hard TPU support. The arch position of the hard support 14 is provided with a plurality of deformation openings 141, which are preferably lotus leaf-shaped half-opening structures. During the wearing process of the insole, after the foot exerts pressure, the center of gravity of the foot sinks along the gravity guide groove 16, and the bilateral hard support 14 is pulled to tightly contact the heel, thereby achieving the effect of stable support of the heel. At the same time, since the arch plays a role of elastic support and buffering of the impact force when the human body falls in the human body movement system, a certain deformation space is required, so the deformation opening 141 with a lotus leaf-shaped half-opening design is adopted on the inner side of the hard support 14, which can not only ensure the stable support of the arch, but also provide sufficient deformation space for the arch.

[0027] With reference to Figure 2 , the bottom surface of the insole body 10 is provided with a shock-absorbing glue module 15 at the heel position, which is a GEL shock-absorbing glue, and its role is to reduce the impact force of the ground on the heel and the spine when the heel position is buffered when falling.

[0028] With reference to Figure 2 , in order to facilitate the deformation of the insole body 10, the bottom surface of the insole body 10 is provided with a bending line (not marked in the figure), and the groove depth of the gravity guide groove 16 is greater than the line depth of the bending line.

[0029] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application using this concept shall be regarded as an act of infringing the protection scope of the present application.
