Taking care of the leather
The Karakorum Evo GTX boots are made of split leather. The lining is assembled with a Gore-Tex waterproof and breathable membrane.
It is vital to take good care of the leather, without damaging the membrane.
First, wash your boots with a soft sponge. Leave them to dry away from any sources of heat, like radiators or fireplaces. Finally, work a waterproofing spray into the leather. DO NOT USE WAX ON THIS MODEL.
