The superior quality of cowhide and innovative processing ensure a prolonged duration of waterproofness and vapor permeability. The complete bottom system is made of Kevlar, which ensures complete impenetrability. The built-in SUN REFLECT system reflects the temperature from the surface of the boot, which achieves thermoregulation. When put on, the boot retains the temperature of the leg. The lining is made of three-layer textile materials with built-in membranes. Membranes ensure wearing comfort. In combination with the outer materials, water resistance and breathability are ensured. The lining has a large number of wear cycles, which increases the durability of the boot. Gel filling in the area of the toes and heel provides ANTI SHOCK effect. Through the rip effect, the “SELF-CLEANING” function is achieved.
