[0025] As Figures 1-6As shown, a gradient antibacterial and breathable upper structure and a compatible sole and heel system include an upper, which includes an outer upper layer 1, an inner upper layer 2, and a mid-layer moisture-wicking layer disposed between the outer upper layer 1 and the inner upper layer 2.

[0026] The outer layer 1 of the shoe upper is made of polyester fiber base fabric (60-80 g / m²), and its surface is coated with a nano-zinc oxide / graphene composite coating (10-15 μm thick, ZnO particle size 40-60 nm, graphene sheet thickness 2-3 nm). The nano-zinc oxide / graphene dispersion (20% solid content) is uniformly coated onto the polyester base fabric by a spraying process, and then dried at 120℃ to form the composite coating. The nano-zinc oxide / graphene composite coating has an antibacterial rate of >99.9% through a dual mechanism of photocatalysis and physical antibacterial action, inhibiting the adhesion of surface microorganisms.

[0027] The inner layer 2 of the shoe upper is made of chitosan-modified cotton fiber fabric (chitosan content 8%, fiber diameter 15μm), which is knitted to form a honeycomb three-dimensional structure (pore size 2-3mm), with a weight of 50g / m². It comes into direct contact with the skin and destroys bacterial cell membranes through positively charged adsorption of chitosan, achieving an antibacterial rate of >95%. The chitosan-modified cotton fiber fabric is made by impregnating cotton fibers with a chitosan acetate solution (concentration 2%), crosslinking at 80℃ for 1 hour, washing and drying, and then knitting.

[0028] The middle directional moisture-guiding layer uses a unidirectional moisture-guiding mesh (pore size 0.5-1mm, tilt angle 45°), which is woven with alternating hydrophobic areas (contact angle 130°±0.5°) and hydrophilic areas (contact angle 20°±0.5°) (e.g. Figure 6 As shown in the image, sweat is wicked away unidirectionally from the inside out. The unidirectional moisture-wicking mesh material is a polypropylene / cotton blend (ratio 3-6:7-4), with a weight of 50-60 g / m² and a tensile strength ≥40 N / cm².

[0029] The shoe upper has several equidistant ventilation holes 3, which are elliptical in shape (5mm major axis, 3mm minor axis), spaced 10mm apart, and arranged in an alternating pattern, accounting for 25%-30% of the total area. Shape memory alloy wires (Ni-Ti alloy, 0.3mm diameter, phase transition temperature 35℃) are embedded at the edges of the ventilation holes 3. As the temperature rises, the alloy wires contract, increasing the expansion area of ​​the ventilation holes 3 by 40%. Breathability tests show that the airflow inside the shoe increases by approximately 5% compared to an upper without ventilation holes, effectively reducing stuffiness and odor.

[0030] The shoe upper has a heel 6 at the rear. The shoe opening formed by the heel 6 and the ventilation holes 3 is covered with a shoe opening reinforcement strip 4. The reinforcement strip is 5-6mm wide and is formed by thermosetting polyurethane injection molding. The reinforcement strip 4 not only enhances the abrasion resistance of the shoe upper edge and prevents pilling and cracking, but also provides a more solid foundation for the subsequent connection with the sole and heel.

[0031] The heel 6 is detachably provided with a heel insertion area 7; and a magnetic attraction structure is arranged between the vamp and the sole 10.

[0032] The heel 6 comprises a heel inner layer 601 and a heel outer layer 602 which are integrally formed, and a dovetail block 603 is arranged on the outer side wall of the heel outer layer 602. The heel insertion area 7 comprises a heel insertion area body 701, and a dovetail groove 703 is arranged on the inner side wall of the heel insertion area body 701 and matched with the dovetail block 603. The dovetail groove 703 has a depth of 4 mm and a width of 5 mm, the dovetail block 603 and the dovetail groove 703 are embedded by a hot pressing process (160℃, 4MPa, 40s), and the tensile strength reaches 18N after a tensile strength test, meeting the use requirement.

[0033] The polyester fiber support sheet 702 is embedded in the heel insertion area body 701, has a thickness of 1.5 mm, and the longitudinal bending strength is improved by 42% compared with the heel without the support sheet after a longitudinal bending strength test, effectively avoiding structural fatigue caused by frequent folding.

[0034] The magnetic attraction structure comprises a magnetic male buckle 8 arranged at the bottom of the vamp, and a magnetic female buckle 9 arranged on the upper end surface of the sole 10 and matched with the magnetic male buckle 8. The magnetic male buckle 8 is made of stainless steel and has a suction force of 3N / buckle, and the magnetic female buckle 9 contains a neodymium iron boron magnet.

[0035] The sole 10 is integrally formed with a sole protection skirt 5 of the protective vamp at the front end.

[0036] The above-described embodiments only describe the preferred modes of the present application, and do not limit the scope of the present application, and various deformations and improvements of the technical solutions of the present application made by those skilled in the art without departing from the design spirit of the present application shall fall within the protection scope determined by the claims of the present application.
