Abstract

The elastic upper of shin boots with a circumferential fixing with a stabilization zone in the front part and a support zone in the back part has a stabilization zone (1) with an elasticity of 10 to 30% less and a total area of 15 to 30% less than the support zone (2), the shin area being provided with a hem (3) with a transverse elasticity of 90 to 98% at the upper edge around the entire circumference of the elastic upper. The hem (3) may be based on a flexible knitwear material of water-repellent yarn, in particular polyamide and / or polyester, or it may be formed of an elastomer, in particular silicone rubber. The line separating the hem (3) from the adjacent shin area is parallel to the line of the upper edge of the shin area so as to form a uniform width of the hem (3) around the entire circumference of the shin. The elastic upper may further comprise at least one deformation zone (4) in the rear part of the shin with a transverse elasticity 20 to 30% higher than the support zone (2).

Abstract

The sole has a flexible tread part (2) with a flexible heel part (3) inseparably joined together through a fixed connecting part (1), overlapping from above at least the perimeter of the heel part (3) and provided with a vertically oriented hem at the outer edges of the sole. The connecting part (1) is provided with perforations (4) in its central zone and has area of perforations (4) covered by a membrane (5) from above. The membrane (5) is preferably a textile water-resistant breathable polymer nanofibre membrane. The area of perforations (4) with the membrane (5) can also be formed in advance as a separate part, subsequently inserted into the corresponding hole in the connecting part (1). Advantageously, the area of perforations (4) can be formed in a given shape directly on the membrane (5) by 3D printing technology. Preferably the tread part (2) and / or the heel part (3) of the sole is provided with an above¬ opened set of lightening cavities (6, 6').
