Specifically, the lower surface of the sealed injection-molded portion 21 is in contact with the upper surface (inner side) of the fabric layer 14, and the outer peripheral side of the sealed injection-molded portion 21 is in contact with the lower edge of the upper 11 and the inner side of the connecting strip 12. The inner surface of the outsole injection-molded portion 22 is in contact with the outer side of the lower edge of the upper 11, the outer side of the connecting strip 12, and the lower surface (outer side) of the fabric layer 14. Thus, the sealed injection-molded portion 21 and the outsole injection-molded portion 22 can seal and wrap around the lower edge of the upper 11, the connecting strip 12, and the fabric layer 14 in the inward and outward directions, thereby protecting and waterproofing the lower edge of the upper 11, the connecting strip 12, and the fabric layer 14. For example, as... Figure 1 As shown, the lower surface of the sole 2 has raised portions to form an anti-slip structure.

[0039] In some embodiments, the sealing injection part 21 and the outer bottom injection part 22 are wrapped around the inner and outer surfaces of the connecting strip 12 and are integrally connected through the injection hole 13 of the connecting strip 12; and / or, the fabric layer 14 is provided with a vent hole 141, and the sealing injection part 21 and the outer bottom injection part 22 are wrapped around the inner and outer surfaces of the fabric layer 14 and are integrally connected through the vent hole 141 of the fabric layer 14.

[0040] like Figure 3 As shown, in some embodiments, the upper 11 includes an upper layer 112 and a waterproof and breathable layer 111, the waterproof and breathable layer 111 being disposed on the inner side of the upper layer 112. This allows the waterproof and breathable layer 111 to be waterproof, preventing rainwater from seeping into the shoe.

[0041] In some embodiments, the upper 11 is composed of the upper layer 112 and the waterproof and breathable layer 111, and the inner side of the upper layer 112 is attached with only the waterproof and breathable layer 111. That is, the upper 11 only includes the upper layer 112 and the waterproof and breathable layer 111, and the waterproof and breathable layer 111 is directly attached to the inner side of the upper layer 112. The waterproof and breathable layer 111 is a thin waterproof and breathable layer, which is mainly used to prevent water from wetting the inside of the shoe 1 from the upper 11, while having the effect of being breathable and not steaming the feet. Since the conventional insole made of cloth, cotton, wool, etc. is omitted, the weight reduction effect is obvious, and the waterproof and breathable layer 111 is directly attached to the inner side of the upper layer 112, avoiding the process of attaching a waterproof film to the insole of the shoe 1, brushing waterproof glue at the sewing line or attaching a waterproof adhesive tape, and sewing the insole to the shoe 1, which is simple in process and simple in structure, and makes the injection-molded waterproof shoe (shoe 1) light, thereby improving the comfort. For example, the upper layer 112 is made of mesh cloth or flyknit material.

[0042] In some embodiments, the waterproof and breathable layer 111 has waterproof property, and the sealing injection-molding part 21 and the waterproof and breathable layer 111 are sealingly connected by injection molding adhesion, and the bottom of the waterproof and breathable layer is embedded in the shoe sole 2 to prevent water from entering the inside of the shoe 1.

The waterproof and breathable layer 111 also has the effect of being breathable and not steaming the feet.

[0043] In some embodiments, the waterproof and breathable layer includes a fabric and a waterproof film, and the waterproof film is attached to the fabric to improve the tear resistance of the waterproof and breathable layer. Specifically, the fabric layer formed by the fabric is wear-resistant and tear-resistant, the micro-holes on the waterproof film have a diameter much smaller than that of water droplets, thereby facilitating waterproofing, and the micro-holes on the waterproof film are larger than the size of water vapor molecules, so that the moisture emitted by the human body can escape through these micro-holes, keeping the inside dry. For example, the waterproof and breathable layer can be a waterproof fabric attached to the inner side of the upper layer 112 by a hot pressing process.
