The paint gets dirty easily but it is also very easy to clean and especially for this kind of shoe it is essential that they are always clean and shiny. To obtain excellent results, the important thing is to use a soft cloth to remove dust and dirt from the upper of the shoe and then, if you want to revitalize the leather, just wipe a lightly soaked cloth with some milk. Or, again to make the paint even shinier, you can pass a little paraffin on the shoes and rub with a soft cloth. The important thing is not to scratch them, therefore the classic brushes that are used for other normal leather shoes should never be used.
As a last step, remember to dry the shoe thoroughly with a clean cloth and never leave the leather excessively damp.
