A sole (10, 100, 200, 300) for shoes, of the waterproof and vapor- permea ble type, comprising: - a lower element (1 1, 111, 211, 311) made of plastic material, on which a tread (12) provided with multiple through holes (13) i s formed; - a membrane (14, 214, 314) which is impermeable to water and perm eable to water vapor and is arranged above said lower element (11, 111, 211, 311) so as to be superimposed on the through holes (13), the membrane being joined perimetrically and hermetically to at least one component of the sol e (10, 100, 200, 300) so as to avoid the rise of liquids through the sole, - vapor-permeable or perforated means (17) for protecting the membrane (14, 2 14, 314), which are arranged below the membrane (14, 214, 314) so as to be s uperimposed on the area of the holes (13). The sole has means (17) for prote cting the membrane (14, 214, 314) comprising individual vapor-permeable or p erforated protective elements (18, 118, 218, 318), each arranged so as to bl ock a corresponding through hole (13). The lower element (11, 111, 211, 311) forms, for each through hole (13), an undercut region (19, 119, 219a, 219c, 219d, 219e) for preventing downward extraction for each protective element (18, 118, 218, 318).
