Regular shoe care is especially important for much-used work shoes. Dirt can hinder the shoes’ breathability and incorrect drying can make the material become brittle. We recommend removing coarse dirt immediately after wearing. For leather use, remove dirt with a brush, lukewarm water, and soap if required. Treat water and snow marks immediately! Regular waterproofing protects and maintains the water-resistant properties of the surface material.
