Abstract
The invention provides a water vapor permeable sole unit (15) including an outsole ply (41) constructed using an outsole material, possibly formed from a plurality of pieces and/or provided with outsole portions arranged thereunder, which outsole ply is thickness reduced within a circumferential region by means of a recess (43) extending from an upper side of the outsole ply (41), and provided with outsole ply through hole openings (45) extending through the thickness thereof. The sole unit (15) possesses a water vapor permeable barrier ply (47) at least partly disposed in the recess (43) of the outsole ply (41), extending only over a partial height of the recess (43) and constructed using a barrier material configured against foreign bodies being forced through. The sole unit (15) possesses a water vapor permeable comfort ply (49) disposed above the barrier ply (47) in the recess (43) and constructed using a comfort ply material having a lower hardness and/or a lower specific density than the outsole material.
