Shoe care: Machine-washable at 30˚ Celsius (85˚ F). Remove the liner and wash/dry separately. Dry in room temperature, do not tumble dry. Of course, it’s also possible to clean the boots with water and a mild detergent. Washcloths and a foam detergent are also very efficient. Avoid solvent based detergents and hard brushes. Don’t forget the inside – be sure to get rid of any sand or gravel.
