This creamy water based non greasy wax is easy to apply to wet or dry leather to maintain the material support, breathability & waterproofing. Regular wetting of untreated boots causes the tanning agents to disappear making the leather susceptible to cracking & weakening. This proofing wax maintains the support of the leather without over softening & replaces the water repellency so your boots stay drier, breathable & lighter. We recommend that you clean your boots with Nikwax Cleaning Gel prior to treating them.
