A waterproof layer is glued to the uppermost edge of the shape memory alloy bracket, and a gradient pore size foam layer is glued to the bottom edge of the waterproof layer. A breathable layer is sewn to the bottom of the gradient pore size foam layer. The microporous hydrophobic membrane enables the shoe surface to achieve stain and water-repellent effects while allowing air circulation to prevent moisture accumulation inside the shoe and keep the feet dry.

Description

Technical Field

[0001] This utility model belongs to the field of footwear material manufacturing technology, specifically relating to a highly efficient breathable footwear material structure. Background Technology

[0002] Breathable shoes, also known as "playful shoes" or "breathable shoes," feature vacuum vents on the upper and sides. These vents regulate the temperature inside the shoe through air convection, offering lightweight, waterproof, and durable properties. They also include insoles with massage particles mimicking acupressure points on the soles of the feet. The design incorporates fashionable canvas shoe elements, primarily targeting office workers and trendsetters. A key feature of breathable shoes is their unique design: numerous vacuum vents are distributed around the shoe's sides. These vents, similar to the convection principle of an accordion, allow air to circulate inside the shoe. Heat is compressed between the vents and expelled through the vents as rising airflow, while cool air enters, creating a natural temperature regulation mechanism. This ensures the feet remain in a comfortable temperature environment. This design maintains the shoe's aesthetic appeal while solving the problem of stuffiness in summer, avoiding the inconvenience of sandals in formal occasions.

[0003] The main problems with existing footwear breathability technology are as follows:

[0004] 1. Insufficient breathability: Traditional polyurethane (PU) materials have poor breathability and strong water absorption, which can easily lead to stuffy and damp feet.

[0005] 2. Waterproof and breathable contradiction: Existing materials cannot simultaneously achieve a high waterproof index (≥8000mmHz) and a high moisture permeability (800g / m2 / 24h);

[0006] 3. Simple structure: Traditional shoe materials are mostly homogeneous and cannot adjust breathability according to the needs of different areas of the foot.

[0007] 4. Poor durability: Ordinary breathable materials are prone to micropore blockage after long-term use, resulting in a decrease in breathability of more than 50%. To address this, we propose a highly efficient breathable shoe material structure. Utility Model Content

[0008] The purpose of this invention is to provide a highly efficient and breathable shoe material structure to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency breathable shoe material structure, including a shape memory alloy bracket and a sole body, wherein a waterproof layer is glued to the uppermost edge of the shape memory alloy bracket, a gradient pore size foam layer is glued to the bottom surface edge of the waterproof layer, and a breathable layer is sewn to the bottom of the gradient pore size foam layer.

[0010] Preferably, the waterproof layer is composed of a microporous hydrophobic membrane, the surface of the gradient pore size foam layer is uniformly provided with multiple sets of airflow channels, and the breathable layer is woven from hydrophilic mesh fabric phase change fibers.

[0011] Preferably, a sole cover is glued to the top of the sole body, the bottom of the shape memory alloy bracket is sewn to the surface of the sole cover, and a sole plate is glued to the bottom of the sole cover.

[0012] Preferably, the bottom surface of the sole cover is provided with a polymer elastic fiber layer, and a shaping plate is provided at the bottom of the polymer elastic fiber layer near the heel.

[0013] Preferably, the bottom surface of the shaping plate is provided with a heat insulation layer, and the polymer elastic fiber layer, the shaping plate, and the heat insulation layer are all located on the inner side of the shoe sole plate.

[0014] Preferably, the surfaces of the shoe sole cover, shoe sole body, polymer elastic fiber layer and shoe sole plate are all provided with ventilation holes, which are interconnected, and a rubber spring air cushion is installed inside the ventilation holes on the surface of the shoe sole plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The microporous hydrophobic membrane allows the shoe surface to achieve stain and water repellency while allowing air circulation to prevent moisture buildup inside the shoe and keep feet dry. The mid-layer of the upper uses a gradient pore size foam layer with different pore sizes distributed together with airflow channels to form a three-dimensional air circulation system, achieving a synergistic effect of waterproofing and breathability. The inner layer of the upper uses a hydrophilic mesh woven with a dense microporous structure to form a three-dimensional ventilation channel, accelerating air circulation during exercise, helping to dissipate heat from the feet, and improving the breathability of the upper.

[0017] 2. The insulation layer maintains sufficient resilience in low-temperature environments, making it suitable for winter sports; and the material has a certain degree of deformation resistance in high-temperature environments, ensuring sustained athletic performance. Ventilation holes allow for air circulation through the sole, reducing moisture buildup on the feet and keeping them dry. 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] Please see Figure 1-2 This utility model provides a technical solution: a high-efficiency breathable shoe material structure, including a shape memory alloy bracket 1 and a sole body 2. A waterproof layer 3 is glued to the uppermost edge of the shape memory alloy bracket 1, a gradient pore size foam layer 5 is glued to the bottom edge of the waterproof layer 3, and a breathable layer 7 is sewn to the bottom of the gradient pore size foam layer 5.

[0024] Specifically, the waterproof layer 3 is composed of a microporous hydrophobic membrane 4, the surface of the gradient pore size foam layer 5 is uniformly provided with multiple sets of airflow channels 6, and the breathable layer 7 is woven from hydrophilic mesh fabric 8 phase change fibers.

[0025] Specifically, a sole cover 9 is glued to the top of the sole body 2, the bottom of the shape memory alloy bracket 1 is sewn to the surface of the sole cover 9, and a sole plate 13 is glued to the bottom of the sole cover 9.

[0026] Specifically, a polymer elastic fiber layer 10 is provided on the bottom surface of the sole cover 9, and a shaping plate 11 is provided on the bottom of the polymer elastic fiber layer 10 near the heel.

[0027] Specifically, a heat insulation layer 12 is provided on the bottom surface of the shaping plate 11, and the polymer elastic fiber layer 10, the shaping plate 11, and the heat insulation layer 12 are all located on the inner side of the shoe sole plate 13.

[0028] Specifically, ventilation holes 14 are provided on the surfaces of the upper cover 9, the sole body 2, the polymer elastic fiber layer 10, and the sole plate 13, and they are interconnected. A rubber spring air cushion 15 is installed inside the ventilation holes 14 on the surface of the sole plate 13.

[0029] In this embodiment, the microporous hydrophobic membrane 4 prevents rainwater and other liquids from penetrating the surface of the shoe, achieving anti-fouling and water-repellent effects. At the same time, it allows air circulation, preventing moisture buildup inside the shoe and keeping the feet dry. The mid-layer of the upper uses a gradient pore size foam layer 5 with different pore sizes distributed together with airflow channels 6 to form a three-dimensional air circulation system, achieving a synergistic effect of waterproofing and breathability. The inner layer of the upper uses a hydrophilic mesh fabric 8 woven with a dense microporous structure to form a three-dimensional ventilation channel, accelerating air circulation during exercise and helping to dissipate heat from the feet. This structure resembles a honeycomb matrix, with multiple breathable holes distributed per square centimeter, significantly reducing humidity inside the shoe. The high-polymer elastic fiber layer 10 naturally stretches and contracts according to foot movement, reducing lateral foot displacement (limited by 35%) and increasing longitudinal support (increased by 22%), reducing toe fatigue during exercise. The shaping plate 11 provides arch support, preventing foot collapse, enhancing running stability, and helping to reduce joint pressure. The heat insulation layer 12, made of nylon composite material, maintains 85% toughness in low-temperature environments (-40℃), suitable for winter sports; in high-temperature environments (35℃), the material deformation is only 1.5%, ensuring endurance during exercise. Ventilation holes 14 allow air circulation through the sole, reducing foot moisture buildup and keeping feet dry. The rubber spring air cushion 15 uses a spring system to absorb ground impact, reducing joint pressure by 18%, improving overall comfort.
