A waterproof breathable vamp comprises a vamp body and a shoe tongue. The vamp body and the shoe tongue are provided with a three-layer structure including a surface waterproof layer, an interlayer waterproof breathable layer and an inner common layer. A shoe tongue wing is arranged on the shoe tongue, the shoe tongue wing is an extension structure of the shoe tongue, the shoe tongue is sewn on the vamp body through the shoe tongue wing, so that the shoe tongue forms a semi-separated shoe tongue, and a hot-pressed PP film is arranged at the sewing position of the shoe tongue wing and the vamp body and seals needle holes in the vamp body. Compared with a traditional waterproof shoe upper with a separated shoe tongue, the waterproof shoe upper solves the problem that water enters shoe eyelets and shoe tongue sewing holes, and the waterproof performance is further improved; compared with an inner sleeve type waterproof vamp, the shoe is simpler in structure and higher in wearing comfort. 一种防水透气鞋面，包含鞋面本体、鞋舌。鞋面本体、
