Description

Technical Field

[0001] The utility model belongs to the technical field of insoles, and specifically relates to a highly elastic and breathable insole. Background Technique

[0002] Shoes, as an indispensable item of daily wear for humans, have a long history, a wide variety of types, and different functions. They not only protect our feet from the harm of the external environment but also become an important expression of fashion and personal style. Among them, the insole is an important part inside the shoes.

[0003] The existing insoles are mainly composed of a fabric layer, a filling layer, etc. Through the material characteristics of these layers, the effects of stable support, moisture absorption, breathability, anti-slip, and wear resistance are achieved to improve the comfort and functionality of wearing.

[0004] At present, the existing insoles in the prior art have the following disadvantages: When jogging, the feet of joggers will experience repeated landing and lifting processes, generating a large impact force. The rebound curve of the traditional insole is rigid and not soft enough when rebounding, affecting the wearing experience of the wearer, with poor comfort and breathability; Therefore, in view of the above problems, a highly elastic and breathable insole is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing insoles and solve the problems that the rebound curve of the existing insoles is rigid and not soft enough when rebounding, affecting the wearing experience of the wearer, with poor comfort and breathability, a highly elastic and breathable insole is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A highly elastic and breathable insole of the utility model includes an insole body, and the insole body includes an upper layer, a soft buffer layer, and a highly elastic layer. An array of channels is provided in the soft buffer layer. The channels include a sole part, a heel part, and an arch part. The pipe diameters of the sole part and the heel part are larger than that of the arch part. The arch part makes the gas flow rate smaller when the gas in the sole part or the heel part flows mutually.

[0007] Preferably, a plurality of through holes are provided in the insole body, and the through holes are in a conical structure, and the aperture of the upper end is smaller than that of the lower end.

[0008] Preferably, a plurality of grooves are provided at the bottom end of the highly elastic layer, and the grooves are in a triangular structure.

[0009] Preferably, the upper layer is made of breathable fabric.

[0010] Preferably, the soft buffer layer is made of foam.

[0011] Preferably, the highly elastic layer is made of foam.

[0012] Preferably, the upper layer, the soft buffer layer, and the high-elasticity layer are stitched and connected by sewing threads.

[0013] Advantages of the present utility model:

[0014] The present utility model provides a high-elasticity and breathable insole. In the soft buffer layer of the insole body, the channel designs in the sole of the foot part, the heel part, and the arch part are such that the diameter of the gas flow decreases in the arch part, enabling the pressure to be gradually dispersed, being soft and having a more gentle rebound curve, so that the insole is not too rigid when rebounding. This design can significantly improve comfort when wearing, reduce foot fatigue and discomfort, and provide a better wearing experience and greater comfort for the wearer; the overall structure of the present utility model is not only comfortable to wear, but also has better breathability, improving the wearing experience.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0024] Next, specific embodiments are given.

[0025] Please refer to Figures 1 - 5 , a highly elastic and breathable insole according to the present utility model, comprising an insole body 1, the insole body 1 including an upper layer 101, a soft buffer layer 102, and a highly elastic layer 103. An array of channels 2 is provided in the soft buffer layer 102. The channels 2 include a forefoot portion 201, a heel portion 202, and an arch portion 203. The diameters of the forefoot portion 201 and the heel portion 202 are larger than that of the arch portion 203. The arch portion 203 causes the gas flow rate to decrease when the gas in the forefoot portion 201 or the heel portion 202 flows mutually; when wearing, place the insole body 1 in the shoe, and the rear foot contacts the upper layer 101. When the wearer exercises or moves, if a downward pressure is applied to the forefoot position, the forefoot portion 201 in the channel 2 is deformed under pressure, and the gas in the forefoot portion 201 is pressured to move, and moves through the arch portion 203 to the heel portion 202. Since the aperture of the arch portion 203 is smaller, when the gas enters the heel portion 202 from the forefoot portion 201 through the arch portion 203, the gas flow rate is small, and the gas will not be immediately pressured to the heel portion 202 area, but gradually and rhythmically enters the heel portion 202 to disperse the pressure, reducing the impact force borne by the foot instantaneously. On the contrary, when the wearer applies pressure to the heel portion 202 through the heel, the gas in the heel portion 202 also gradually flows into the forefoot portion 201 in the same principle as above, and the principle will not be elaborated here; this design makes the insole softer rather than too rigid when rebounding, with a soft rebound curve, and increases the buffering time of the insole, so that the pressure is gradually dispersed to play a role in buffering and shock absorption, which is particularly effective in reducing the impact force on the foot, especially significantly improving the comfort when jogging or standing for a long time.

[0026] Furthermore, a plurality of through holes 3 are provided in the insole body 1. The through holes 3 are in a conical structure, and the upper aperture is smaller than the lower aperture. When wearing, the conical through holes 3 are more conducive to guiding the air flow. Especially when there is an air pressure difference between the sole and the upper, the larger lower aperture can increase the air outflow rate, which is more conducive to moisture discharge. And because the upper aperture is smaller than the lower aperture, when the insole body 1 is under pressure, the air in the through holes 3 will be compressed to a certain extent when flowing upward, thereby accelerating the flow, improving the breathability of the insole, keeping the feet dry, reducing the growth of bacteria, and at the same time, under the premise of the same material, the insole body 1 is lighter in weight with the conical design of the through holes 3.

[0027] Furthermore, a plurality of grooves 4 are provided at the bottom end of the high-elastic layer 103. The grooves 4 are triangular in structure. When worn, the triangular grooves 4 can form multiple contact points at the bottom of the insole body 1, increasing the friction with the inner surface of the shoe sole and effectively preventing the insole from moving or sliding during use. When the insole body 1 is pressed and restored to its original state, the triangular grooves 4 will provide additional resilience, improving the foot feeling, which is particularly suitable for foot movements during jogging. Moreover, the groove 4 structure at the bottom of the high-elastic layer 103 means less material, which will further reduce the overall weight of the insole body 1 and enhance the lightweight effect of the sports shoes without affecting the support and comfort.

[0028] Furthermore, the upper layer 101 is made of breathable fabric. When worn, since the upper layer 101 is in direct contact with the wearer's foot, the breathable fabric can provide good breathability and comfort for the wearer.

[0029] Furthermore, the soft buffer layer 102 is made of foam. When worn, the soft buffer layer 102 made of foam provides excellent comfort and support. The inside of the foam material has a dense structure of breathable holes, and at the same time has good breathability and lightweight characteristics, enabling the insole body 1 to effectively improve resilience, comfort, reduce fatigue, and extend the service life of the insole during daily wear.

[0030] Furthermore, the high-elastic layer 103 is made of foam. When worn, since the high-elastic layer 103 is in direct contact with the inner bottom of the shoe during use, the foam material of the high-elastic layer 103 has a relatively larger density and is more wear-resistant than the foam material of the soft buffer layer 102, increasing the service life of the insole.

[0031] Furthermore, the upper layer 101, the soft buffer layer 102, and the high-elastic layer 103 are connected by sewing threads. Compared with the common glue connection method, the sewing thread connection process greatly ensures the breathability of the insole, while the glue will seal the breathable structure and make it unable to function.
