Pre-Treated Leather: The boot arrives pre-treated with a hydrophobic finish from the factory.

Cleaning: Remove dirt and mud using warm water and a soft brush. Let the boots air dry naturally away from direct heat sources, then brush gently with a suede brush to restore the nap.

Important: Do not use soap, as soap dissolves the leather's hydrophobic oil treatment. Waterproofing spray can be reapplied periodically after cleaning once dry.
