1. After use wash your boots to remove any mud, stones, or old wax, and allow them to dry at room temperature.
2. Never force dry boots near a fire or other heat source as it damages the leather and can shorten the life of the boot.
3. To speed dry, remove the insoles and stuff the boots with newspaper, and change regularly as it becomes wet.
4.  When the boots are completely dry and clean, apply wax (if necessary) and store in a cool, dry, well-ventilated place.
