Breathable outsole (11) for footwear, in which the outsole has a two-layer structure. The two-layer structure contains an elastic and water vapor-permeable inner layer (1) and an outer layer (2) that covers less than 70% of the inner layer (1).The breathing activity of outsole (11) is guaranteed by the preferably microporous structure of inner layer (1) and the configuration of outer layer (2). The configuration of outer layer (2) is such that the surface of inner layer (1) available for water vapor exchange is restricted as little as possible. A microporous structure of insole (1) is achieved, for example, by a sintered plastic.
