FIELD: personal use articles.
SUBSTANCE: invention relates to a sole unit for a footwear product that permeable for water steam and water; the unit has one sole layer with one aperture (passing along the thickness and haling a large area), two planar layers positioned over each other; each planar layer is made integral of composite and covering at least one aperture, the first planar layer having a textile barrier layer permeable for water steam while the second planar layer has a caching layer permeable for water steam, positioned under the first planar layer, covering the said first planar layer at least within the zone of at least one aperture and visible from the sole underside within at least one aperture; the barrier layer is designed as protection against foreign bodies (as may penetrate through the aperture having a large area) reaching the sole unit components positioned over the first planar layer as well as for protection against piercing foreign bodies such as nails; the barrier layer is made piercing-resistant, the sole unit permeability for water steam being within the range from 1.000 g/m2 per 24 h to 20.000 g/m2 within 24 h, in particular - within the range from 6.000 g/m2 per 24 h to 12.000 g/m2 within 24 h, in particular - 9.337 g/m2 within 24 h.
EFFECT: ensuring protection against piercing foreign bodies combined with ensuring the sole steam- and water-permeability.
