Material & Care

Vegan Leather (Synthetic)
  • Use a soft, dry cloth to remove surface dust and dirt.
  • For deeper cleaning, mix a small amount of mild clear soap with warm water.
  • Dampen a soft cloth or sponge with the solution and gently wipe the surface.
  • Wipe again with a clean, damp cloth to remove any soap residue.
  • Allow to air dry at room temperature, away from direct heat or sunlight.
  • For mixed-materials areas (textile, rubber, EVA, Cork), mix a small amount of mild clear soap with warm water, dip a soft sponge or soft-bristled brush into the solution and gently clean the area, rinse the sponge with clean water and remove any excess soap, allow to air dry completely before wearing.


  • Avoid:
  • Harsh chemicals, alcohol, or abrasive brushes.
  • Machine washing or soaking.
  • Leather conditioners or oils (not needed for synthetic materials).
  • Always test any cleaning method on a small, hidden area before cleaning the entire product.
