Meindl Wetproof is designed for improving the water resistance of your boot or shoe, whether it is leather, nubuck or fabric. Use every third time your boots are cleaned and spray on before waxing for best results. Spraying is best done when your boots are not completely dry after cleaning, this means the pores are still open and the product can penetrate deeper. Spray the wetproof onto your footwear, leave for 5 minutes and then spray again. Leave for at least 12 hours to dry out.
