Description

Technical Field

[0001] This utility model relates to the field of shoe midsole technology, and in particular to a foamed midsole with good flexibility. Background Technology

[0002] Shoes are necessities in people's daily lives, serving not only the basic functions of protecting the feet and facilitating walking, but also typically consisting of multiple parts, including the sole, upper, insole, and laces (or zippers, Velcro, etc.). The sole is one of the most important components, and it is further divided into a foam midsole and an outsole. The foam midsole, located between the sole and insole, provides support, cushioning, and comfort.

[0003] To address this, patent specification CN212165097U discloses a reflective shoe midsole. The reflective shoe midsole is a one-piece molded structure with light transmission. Multiple randomly dispersed reflective microbeads are arranged within the reflective shoe midsole. The reflective shoe midsole includes an edge portion and a wedge-shaped support portion. The support portion has an upward-facing contact surface, and the edge portion is located above the contact surface and extends along its outer edge. This reflective shoe midsole has the advantage of stable reflective effect.

[0004] The aforementioned technology provides a stable reflective effect when used in reflective shoe midsoles. However, during long runs, the feet generate heat, and traditional midsoles are not good at dissipating this heat, leading to sweaty feet. Therefore, a flexible foam midsole is needed to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a flexible foam midsole to solve the problem of poor heat dissipation in existing foam midsoles during use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible foamed midsole, comprising a foamed midsole body; a heat dissipation structure is provided at the top of the foamed midsole body, and an auxiliary structure is provided at the middle position of the foamed midsole body; the heat dissipation structure includes heat dissipation holes, through holes and air bladders, the through holes are opened inside the top of the foamed midsole body, the top of the through holes is provided with heat dissipation holes, and an air bladder is installed on one side of the through holes inside the foamed midsole body.

[0007] Preferably, a plurality of heat dissipation holes are provided, and the plurality of heat dissipation holes are arranged at equal intervals on the surface of the foamed insole body.

[0008] Preferably, a plurality of through holes are provided, and the through holes are arranged at equal intervals on both sides inside the foamed insole body.

[0009] Preferably, the auxiliary structure includes a carbon plate, an anti-slip strip, and an adhesive layer. The carbon plate is bonded to the middle position of the foamed midsole body, and the upper and lower surfaces of the carbon plate are coated with the adhesive layer. The anti-slip strip is installed at the bottom end of the foamed midsole body.

[0010] Preferably, a plurality of anti-slip strips are provided, and the plurality of anti-slip strips are arranged at equal intervals at the bottom end of the foamed insole body.

[0011] Preferably, the material of the foamed midsole body is EVA.

[0012] Preferably, the anti-slip strip is made of EVA and integrally molded with the foamed midsole body.

[0013] The present invention provides a flexible foamed midsole, the advantages of which are:

[0014] By using the combination of heat dissipation holes, through holes, and air bladders, the air bladders can deform when the foam midsole body is squeezed, allowing air under the foot to flow through the heat dissipation holes and inside the through holes. When the foot is not squeezing the foam midsole body, the air bladders will cause the foam midsole body to return to its original position and draw air into the through holes, thereby completing the heat dissipation work for the sole of the foot.

[0015] The foam midsole is made of EVA, which gives it good flexibility. The high strength of the carbon plate effectively maintains the upward curve of the forefoot. During running, this helps the runner's center of gravity to transition from the heel to the toes more quickly, thereby reducing push-off time and improving running efficiency.

[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] This utility model embodiment provides a flexible foamed midsole, such as... Figures 1-5 As shown, a flexible foamed midsole includes a foamed midsole body 1; a heat dissipation structure 2 is provided at the top of the foamed midsole body 1, and an auxiliary structure 3 is provided at the middle position of the foamed midsole body 1.

[0024] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The heat dissipation structure 2 includes heat dissipation holes 201, through holes 202 and airbags 203. The through holes 202 are opened inside the top of the foamed midsole body 1. The top of the through holes 202 is provided with heat dissipation holes 201. An airbag 203 is installed on one side of the through holes 202 inside the foamed midsole body 1. There are several heat dissipation holes 201. The several heat dissipation holes 201 are arranged at equal intervals on the surface of the foamed midsole body 1. There are several through holes 202. The through holes 202 are arranged at equal intervals on both sides inside the foamed midsole body 1.

[0025] Specifically, in this embodiment: through the combined use of the heat dissipation holes 201, the through holes 202, and the air bladder 203, the air bladder 203 can deform when the foamed midsole body 1 is compressed, allowing air under the foot to flow through the heat dissipation holes 201 and inside the through holes 202. Furthermore, when the foot is not compressing the foamed midsole body 1, the air bladder 203 will return the foamed midsole body 1 to its original position, drawing air into the through holes 202, thereby completing the heat dissipation work for the sole of the foot.

[0026] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: Auxiliary structure 3 includes carbon plate 301, anti-slip strip 302 and adhesive layer 303. Carbon plate 301 is bonded to the middle position of foam midsole body 1. The upper and lower surfaces of carbon plate 301 are coated with adhesive layer 303. Anti-slip strip 302 is installed at the bottom end of foam midsole body 1. Several anti-slip strips 302 are provided and are arranged at equal intervals at the bottom end of foam midsole body 1. The material of foam midsole body 1 is EVA. The material of anti-slip strip 302 is EVA and is integrally molded with foam midsole body 1.

[0027] Specifically, in this embodiment, the foam midsole body 1 is made of EVA, which gives it good flexibility when manufactured into a foam midsole. Furthermore, the high strength of the carbon plate 301 effectively maintains the upward curve of the forefoot of the running shoe. During running, this helps the runner's center of gravity transition more quickly from the heel to the toes, thereby reducing push-off time and improving running efficiency. The use of the anti-slip strip 302 enhances the friction at the bottom of the foam midsole body 1, making it less likely to detach when bonded to the outsole.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
