Description

Waterproof and breathable shoe sole TECHNICAL FIELD

[0001] The present application relates to the technical field of shoe sole, in particular to a waterproof and breathable shoe sole. BACKGROUND

[0002] The shoe sole is an important part of the shoe, and the weight, elasticity and material of the shoe sole directly affect the comfort of the shoe. With the improvement of production technology, the types and functions of shoes are becoming more and more diversified to meet the needs of different consumers.

[0003] The utility model discloses a waterproof and breathable shoe sole and a shoe adopting the waterproof and breathable shoe sole, which are disclosed in the authorized announcement CN202262492U. The waterproof and breathable shoe sole comprises a tightly connected outsole and a midsole, and a waterproof and breathable layer made of waterproof and breathable material. The outsole and the midsole are internally provided with outsole air holes penetrating through the upper and lower surfaces of the outsole. The shoe is waterproof and breathable, but the shoe sole still has some deficiencies. The shoe sole lacks a protective structure, and sharp objects on the ground can directly penetrate the air holes and pierce the waterproof cloth layer, which can easily cause foot injuries and pose a safety hazard, thereby causing inconvenience to people walking.

[0004] SUMMARY

[0005] The present application provides a waterproof and breathable shoe sole to solve the problem of lacking a protective structure and posing a safety hazard in the existing waterproof and breathable shoes.

[0006] The present application adopts the following technical solutions:

[0007] The waterproof and breathable shoe sole comprises a midsole. The top of the midsole is provided with a mounting groove. The bottom surface and the side surface of the midsole are provided with a plurality of air holes communicating with the mounting groove. The mounting groove is filled with a gasket. The gasket is integrally formed with a waterproof layer and a supporting layer. The supporting layer is provided with a through hole corresponding to the air hole at the bottom of the mounting groove. The through hole is provided with a plurality of anti-piercing baffles extending obliquely.

[0008] Further, the through hole of the supporting layer is provided with a convex edge, which is inserted into the air hole.

[0009] Further, the waterproof layer is a waterproof and breathable cloth.

[0010] Further, the anti-piercing baffles have an inclination angle of 50° to 75°, and preferably an inclination angle of 60°.

[0011] Further, the supporting layer is made of TPU material or nylon, and preferably the supporting layer is made of TPU material.

[0012] Further, the midsole is provided with an outsole attached to the sole and the heel.

[0013] In another aspect, the application also provides a shoe using the shoe sole.

[0014] From the above description of the structure of the application, compared with the prior art, the application has the following advantages:

[0015] 1. The shoe sole of the application is filled with a gasket which is integrally formed by stacking a waterproof layer and a supporting layer, and can be produced in batches as a spare part, thus improving production efficiency.

[0016] 2. The supporting layer of the application is provided with a puncture-proof baffle which protrudes outward from the through hole of the supporting layer in a diagonal direction, preventing the ground sharp objects from penetrating the through hole and piercing the foot bottom, thus protecting the foot bottom from being pierced when walking on the ground, and ensuring safe and reliable use.

[0017] 3. The supporting layer of the application is provided with a puncture-proof baffle which protrudes outward from the through hole of the supporting layer in a diagonal direction, preventing sand particles from blocking the above-mentioned air holes, keeping the air holes unobstructed, and improving the air permeability of the shoe sole.

[0025] The specific embodiments of the application will be described below with reference to the accompanying drawings.

[0026] With reference to FIG. 1 to FIG. 7, a waterproof and breathable shoe sole includes a midsole 1, a mounting groove 10 is formed on the top of the midsole 1, the groove opening of the mounting groove 10 faces upward, the bottom surface and the side surface of the midsole 1 are both provided with a plurality of breathable holes 101 which are communicated with the mounting groove 10, the shoe sole can flow with the outside air through the breathable holes 101, a gasket 2 is filled in the mounting groove 10, the gasket 2 is integrally formed with a waterproof layer 21 and a supporting layer 22 in a mold, the waterproof layer 21 is compounded on the top of the supporting layer 22, the supporting layer 22 is provided with a through hole 20 which corresponds to the breathable hole 101 at the bottom of the mounting groove 10, a plurality of anti-puncture baffles 201 which extend obliquely are arranged in the through hole 20, the plurality of anti-puncture baffles 201 are inclined in the same direction, the anti-puncture baffles 201 are provided with gaps, the gaps keep the breathability of the through hole 20, the plurality of anti-puncture baffles 201 synchronously shield the through hole 20, so that the sharp objects on the ground are not easy to pierce the waterproof layer 21 along the through hole 20 and hurt the sole of the foot.

[0027] The through hole 20 of the supporting layer 22 is provided with a convex edge 202 which is inserted into the breathable hole 101, the convex edge 202 facilitates the alignment of the through hole 20 with the breathable hole 101.

[0028] In the preferred embodiment, the breathable holes at the bottom of the mounting groove in the application are arranged in the middle area of the sole of the foot and the arch area, but not arranged in the edge area of the sole of the foot and the heel area. This arrangement can not only ensure good breathability, but also can ensure that the supporting strength of the shoe sole is not significantly affected, because when wearing shoes, the main weight of the human body is mainly borne by the edge area of the sole of the foot and the heel area, and the middle area of the sole of the foot and the arch area sweat more, so that the arrangement of the breathable holes in these areas can achieve better breathability.

[0029] The waterproof layer 21 is a breathable waterproof cloth.

[0030] With reference to FIG. 3, with reference to the bottom surface of the midsole 1, the inclination angle of the anti-puncture baffle 201 is 50°-75°, and the inclination angle is preferably 60°. The inclination direction of the anti-puncture baffle 201 is backward, that is, as shown in FIG. 3, the direction of the heel is inclined.

[0031] The supporting layer 22 is made of TPU material or nylon, and the supporting layer 22 is preferably made of TPU material.

[0032] With reference to FIG. 4, FIG. 5 and FIG. 7, the sole 11 is adhered to the sole of the foot and the heel of the midsole 1.

[0033] The shoe sole of the present application is filled with a gasket 2 which is integrally formed by superimposing a waterproof layer 21 and a supporting layer 22, and can be produced in batches as a spare part, thus being high in production efficiency; the supporting layer 22 is provided with a puncture-proof baffle 201 which extends outwards from the through hole 20 of the supporting layer 22 in a slanting direction, thus preventing the ground sharp objects from penetrating through the through hole 20 to pierce the sole, protecting the sole from being pierced by the ground sharp objects when walking, and being safe and reliable in use; the supporting layer 22 is provided with the puncture-proof baffle 201 in a slanting direction, thus preventing sand from blocking the above-mentioned air holes, keeping the air holes unobstructed, and making the shoe sole good in air permeability.

[0034] Correspondingly, the present application also provides a shoe which adopts the shoe sole described in the present application.

[0035] The above is merely a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential change to the present application by using the concept shall be deemed as an infringement of the protection scope of the present application.
