Shoe upper having a lower end of the upper, an outer material with a lower end (19) of the outer material, a waterproof functional layer (16), which has a lower end region of the functional layer with a functional layer zone (20) not covered by outer material, and a connecting band (17), which extends in the direction of the periphery of the upper, has a upper longitudinal side (23) of the connecting band, joined to the end (19) of the outer material, and a lower longitudinal side (25) of the connecting band, at least partially overlaps the functional layer zone (20) and consists of liquefiable sealing material or of material through which liquid sealing material (37; 41) can flow, the connecting band (17) having at points of curvature of the lower end (19) of the outer material an arcuate shape corresponding to the local radius of curvature, with different degrees of curvature of the two longitudinal sides (23, 25) of the connecting band, in such a way that, for an arc sector lying in the respective curvature, with a predetermined unitary sector angle, the arc lengths belonging to this arc sector of the two longitudinal sides (23) of the connecting band differ from each other all the more the greater the curvature in the arc sector respectively being considered.
