We love rainboots but rubber is ultimately a perishable product, so you need to take care of them in order to prolong their life.
We advise that you:
DO NOT leave your rainboots in direct sunlight.
DO NOT store them outside.
DO keep them indoors in a cool, dry place.
DO NOT put your rainboots on a radiator or boiler to dry, as this may cause them to split.
Prolonged exposure to hot sun or freezing conditions may make the rubber perish, crack and split.
To clean your rainboots, use water and leave them to dry in a cool, dry place.
When removing your rainboots, do not use a step, bootjack or the toe of your other boot to remove them as this will cause stress to rubber joints and may result in the boots splitting.
