Care Guide
Care Guide
Remove the coarse dirt in the first place.
Keep your shoes clean with our gentle cleaning spray, applied using a cloth, brush, or sponge. Remember to remove excess liquid. Alternatively, a damp cloth can be used.
For added water resistance, use our waterproofer spray. You can also use our odor eliminator spray to absorb unpleasant odors.
Allow your shoes to air dry naturally away from direct sunlight before wearing them.
Do not use polish cream, washing machines, or submerging the shoes in water to prevent irreversible damage.
