Cleaning the product must be carried out as described:
The footwear must absolutely NOT be washed by immersion, under a jet of water or in the washing machine.
For the technical fabric upper, use a cloth slightly dampened with water and neutral soap, rub gently and leave to dry;
For leather uppers, use specific creams (moisturizing-polishing) specific for the type of leather to be treated and approved by the EEC, spread and polished with a clean, dry, soft and non-abrasive cloth;
In the case of suede or similar, only use brushes or soft cloths and only when the skin is dry to remove any stains (mud and similar);
Make sure to regularly hydrate the leather by applying specific creams, especially in the case of particularly soft leathers such as nappa, deer and cevati;
Do not use alcoholic liquids, abrasive liquids, detergents, alcohol, laundry detergents, bleach, ammonia, solvents;
Do not use abrasive materials and/or products, brushes, steel wool, glass paper, blades or similar to remove stains or residues;
For the lower lateral surface of the sole, use soft sponges moistened in warm water, maximum 30 C° and neutral soap;
