The comfort of waterproof footwear is dependent on it supporting feet and being breathable. The structure of leather and therefore the level of support it provides is maintained by tanning agents. When leather absorbs water, tanning agents are lost, which causes leather to stiffen.
Nikwax Waterproofing Wax for Leather™ is a safe product to use on breathable waterproof footwear. It provides instant Durable Water Repellency (DWR), maintains breathability and replenishes tanning agents in leather. It is non-flammable, contains no harmful solvents and is free of volatile organic compounds (VOCs) and fluorocarbons.
Nikwax Waterproofing Wax for Leather™ has been specifically designed and optimized for smooth-out leather footwear. The water-based formulation is directed to leaks, can be used on wet or dry leather and will not over-soften.
This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
