Avoid any heat heater (fireplace, car radiator, sun, domestic radiator). The increased temperature may weaken the bond between the parts of the shoe, for example, the detachment of the sole and / or the destruction of the membrane. If water enters the top of the shoe, let it dry in a dry and shady place in a natural way, or use materials such as a newspaper or paper by placing them inside to absorb moisture faster. Do not use maintenance products more frequently than recommended (1 to 2 times per year depending on usage frequency). You prefer AKU maintenance products. Keep your shoes clean and dry, stored in a dry and shady place.
