Advice The use of a washing machine is strictly discouraged to avoid altering the properties of the different materials.- Waterproof your shoes using a product suited to the material. Repeat this operation every 3 to 6 months.- Maintain the C.W.L leather of your shoes with a damp cloth and a specific spray product. Finish by applying a protective balm. Repeat this operation every 3 months depending on the condition of your shoes.- Let them air dry, away from heat sources (sunlight or radiator), to prevent discoloration.
