A waterproof and vapor-permeable shoe (10), which comprises an upper (11) that is lined at least partially by an upper membrane (12) which is impermeable to water in the liquid state and permeable to water vapor. The upper membrane (12) is connected hermetically to a sole (13) which is impermeable to water in the liquid state. The hermetic connection is provided by means of a sealing element (14) comprised in an assembly insole (15). The sealing element (14) is permeable with respect to sealing material, such as glue, sealing adhesive or polymeric material for providing the sole, and is impregnated with the sealing material, which grips the upper membrane (12) and is connected to the sole (13) or forms a single body therewith, sealing it to the upper membrane (12).
