Description

Technical Field

[0001] This utility model relates to the field of shoe upper structure technology, and in particular to a waterproof and breathable shoe upper. Background Technology

[0002] With the increasing popularity of outdoor activities and functional footwear, the upper, as a crucial component of the shoe structure, not only fulfills the basic functions of protecting the feet and connecting the sole, but also demands higher standards for wearing comfort and adaptability to various usage scenarios. Especially in complex outdoor environments such as mountaineering, hiking, and training, users require uppers to possess not only excellent support and impact resistance, but also stringent requirements for waterproofing and breathability.

[0003] In existing technologies, shoe uppers mostly use fabric or synthetic leather as a base, supplemented by localized waterproofing treatments, such as applying waterproofing agents or splicing waterproof fabric layers to achieve a waterproof effect. At the same time, to enhance breathability, ventilation holes are often incorporated into the upper surface or microporous membrane materials are laminated. While these structures achieve a balance between waterproofing and breathability to some extent, they suffer from problems such as complex manufacturing processes, poor material stability, and the potential for ventilation pathways to fail.

[0004] However, in rainy or humid environments, existing shoe upper structures generally suffer from insufficient waterproofing and limited breathability, leading to stuffiness and dampness inside the shoe and affecting the wearing experience. Furthermore, the lack of structural support can easily cause the upper to deform or collapse, affecting its lifespan and stability. Therefore, a waterproof and breathable upper is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waterproof and breathable shoe upper, which aims to improve the existing technology where the waterproof materials used lack structural support and are prone to deformation or collapse, affecting the service life and stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof and breathable shoe upper, comprising a shoe upper body, wherein a waterproof layer and a support mesh layer are sequentially attached to the outer side of the shoe upper body, a breathable membrane is provided in the middle of the waterproof layer and the support mesh layer, a comfortable lining is provided on the inner side of the shoe upper body, and a toe reinforcement piece is provided at the front end of the shoe upper body to enhance the deformation resistance of the front end.

[0007] Furthermore, multiple shoelace holes are provided on both sides of the upper body. The shoelace holes penetrate the waterproof layer and the support mesh layer and are used to thread shoelaces through for tightening and fixing.

[0008] Furthermore, the lower part of the upper body is provided with a central pressure-relieving pad, which is used to provide cushioning support to the instep during walking.

[0009] Furthermore, the upper side of the shoe upper body is provided with ventilation holes and a waterproof cover sheet. The ventilation holes and the waterproof cover sheet work together to maintain breathability while blocking water. A seam sealing layer is provided at the seams to prevent water seepage.

[0010] Furthermore, the comfortable lining is made of foam material, fits the inner wall of the main body of the shoe upper, and has moisture-wicking and rebound cushioning functions.

[0011] Furthermore, an adhesive layer is provided between the vent and the waterproof cover to enhance the bonding strength between the functional layers and improve the overall structural stability.

[0012] Furthermore, the supporting mesh layer is a nylon fiber mesh structure, used to enhance the three-dimensional support and structural stability of the shoe upper.

[0013] Furthermore, the waterproof cover is fixed to the inside of the vent hole by a hot-pressing process, forming a micro-elastic protrusion structure, which is conducive to moisture removal and enhances visual recognition.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this invention, a waterproof layer and a supporting mesh layer are sequentially bonded to the outer side of the main body of the shoe upper, with a breathable membrane sandwiched between them, effectively achieving a balance between waterproof and breathable performance. The waterproof layer has excellent water-resistant capabilities, while the breathable membrane has microporous ventilation functions; together, they keep the inside of the shoe dry in rainy or humid environments. The supporting mesh layer serves as structural support, enhancing the overall stiffness of the shoe upper and resisting deformation. The toe reinforcement plate enhances the impact resistance of the forefoot, prevents toe collapse, improves wearing stability, and extends the lifespan of the shoe upper.
