Care Instruction cst
Synthetically-tanned leathers are extremely sensitive to humidity. Therefore, wipe dirt off gently using a soft cloth. Moisture - both from inside or outside - can leave marks and result in colour changes. Liquids like oil and even dirt also can leave irreversible stains on the leather.
Do not overdo the use of shoe care products, as this can block the leather pores and result in colour changes. For the occasional care of all plain leathers we recommend, for example, "Collonil Waterstop Colours".
