An insole

Abstract

This utility model relates to an insole, including an insole body. The insole body includes a soft pad layer and a support layer located below and in contact with the soft pad layer. A reinforcing piece is embedded between the soft pad layer and the support layer. The reinforcing piece has the same shape as the insole body and is hollowed out in the middle in a ring shape. A limiting groove for accommodating the reinforcing piece is provided on the support layer. The beneficial effects of this utility model are: the reinforcing piece provides good fixation and improves strength; the size of the reinforcing piece is smaller than the size of the insole body, which can hide the reinforcing piece and make the overall appearance more aesthetically pleasing; the hollowed-out structure in the middle can reduce weight; and the limiting groove can prevent displacement during use and avoid damaging the connection between the soft pad layer and the support layer.

Description

Technical Field

[0001] This utility model relates to the field of shoe insole technology, and in particular to a shoe insole. Background Technology

[0002] Insoles, also known as shoe insoles, are padding placed inside shoes to increase comfort, support the feet, and protect the shoes. Depending on the material, function, and purpose, insoles can be divided into various types, such as cotton insoles, EVA insoles, latex insoles, silicone insoles, shock-absorbing insoles, orthotic insoles, height-increasing insoles, and warming insoles. Insoles with moderate firmness provide a good feel, relieving pressure on the feet during long walks and standing, reducing fatigue and discomfort. Insoles can provide extra support inside the shoe, helping to adjust gait, improve posture, reduce foot fatigue, and reduce sports injuries. Using insoles can extend the lifespan of shoes, reduce wear and stains, and protect the inside of the shoe from foot sweat. Some special materials can play a corrective role for foot deformities such as flat feet and high arches, improving foot shape and health.

[0003] In the existing technology, many insoles are made of sponge in order to make them feel soft underfoot. The overall texture is relatively soft. However, when people with sweaty feet use these insoles, or after a period of use, the insoles are prone to being pulled out or bent upwards when slipping on slippers. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insole to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model is implemented as follows: an insole includes an insole body, the insole body includes a soft pad layer and a support layer located below the soft pad layer and in contact with the soft pad layer, a reinforcing piece is embedded between the soft pad layer and the support layer, the reinforcing piece has the same shape as the insole body and is hollowed out in the middle in the shape of a ring, and a limiting groove for accommodating the reinforcing piece is provided on the support layer.

[0006] By adopting the above technical solution, the reinforcement plate plays a good role in fixing and improving strength. The size of the reinforcement plate is smaller than that of the insole body, which can hide the reinforcement plate and make the overall appearance more beautiful. The hollow structure in the middle can reduce weight, and the setting of the limiting groove can prevent displacement during use and avoid damage to the connection between the padding layer and the support layer.

[0007] The present invention is further configured such that the surface of the reinforcing sheet has several through holes.

[0008] By adopting the above technical solution, the through holes can not only further reduce the weight but also improve the breathability. Both the cushion layer and the support layer are provided with breathable holes.

[0009] The present invention is further configured such that: a positioning block is provided at one end of the reinforcing sheet facing the support layer, and a positioning groove is provided in the limiting groove of the support layer to engage with the positioning block.

[0010] By adopting the above technical solution, the cooperation between the positioning block and the positioning groove facilitates production and prevents them from shifting on the production line.

[0011] The present invention is further configured such that the reinforcing sheet is made of plastic material.

[0012] By adopting the above technical solution, the production cost is low and the strength is high.

[0013] The present invention is further configured such that the cushion layer is made of TPU material or sponge.

[0014] By adopting the above technical solution, the padding layer is in direct contact with the soles of the feet, and this material is relatively soft during use.

[0015] The present invention is further configured such that the support layer is made of EVA material.

[0016] By adopting the above technical solutions, the strength can be further improved.

[0017] The present invention is further configured such that: a plurality of granular protrusions are provided at the end of the support layer away from the cushion layer.

[0018] By adopting the above technical solution, the raised design increases the coefficient of friction between the insole and the midsole of the shoe, further preventing displacement. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model discloses an insole, including an insole body. The insole body includes a soft pad layer 1 and a support layer 2 located below and in contact with the soft pad layer 1. A reinforcing piece 3 is embedded between the soft pad layer 1 and the support layer 2. The reinforcing piece 3 has the same shape as the insole body and is hollowed out in a ring shape in the middle. A limiting groove 201 is provided on the support layer 2 to accommodate the reinforcing piece 3. The reinforcing piece 3 plays a good role in fixing and improving strength. The size of the reinforcing piece 3 is smaller than the size of the insole body, which can hide the reinforcing piece 3 and make the overall appearance more aesthetically pleasing. The hollow structure in the middle can reduce weight. The limiting groove 201 can prevent displacement during use and avoid damage to the connection between the soft pad layer 1 and the support layer 2.

[0024] The reinforcing sheet 3 has several through holes 302 on its surface. The through holes 302 not only further reduce the weight but also improve the breathability. Both the cushion layer 1 and the support layer 2 are provided with breathable holes.

[0025] A positioning block 301 is provided at one end of the reinforcing plate 3 facing the support layer 2, and a positioning groove is provided in the limiting groove 201 of the support layer 2 to engage with the positioning block 301. The engagement of the positioning block 301 and the positioning groove facilitates production and prevents displacement on the production line.

[0026] The reinforcing sheet 3 is made of plastic. It has low production cost and high strength.

[0027] The padding layer 1 is made of TPU material or sponge. Since the padding layer 1 comes into direct contact with the soles of the feet, this material provides a soft feel during use.

[0028] The support layer 2 is made of EVA material, which further enhances its strength.

[0029] The support layer 2 has several granular protrusions at the end away from the padding layer 1. The protrusions increase the coefficient of friction between the insole and the shoe midsole, further preventing displacement.

[0030] The cushioning layer 1 and the support layer 2 are infused with Ula grass during production, which can play a certain role in antibacterial and deodorizing.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
