Boots are made of waterproof nubuck and a membrane inside. Microporous Windtex VTF50 membrane with very high waterproofness, a durable outer surface and a protective inner layer. The seams of the membrane are sealed on special equipment that we use in our production to create tactical shoes for the military. Sealing the seams guarantees complete water insulation. And the quality and density of the membrane will provide comfort and warmth at low winter temperatures. The model also has a sole with a durable tread made of thermoelastoplast material.
