Nikwax 4A2 Leather Waterproofing Wax, 3.4 oz

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. Also, when leather gets wet the breathability of footwear is impaired, giving you damp feet. Therefore, it's essential that the durable water repellency (DWR) of your footwear is maintained. Eventually DWR will wear off and need to be renewed with Nikwax Waterproofing Wax for Leather™. 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's 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 leather footwear. The water based formulation is directed to leaks, can be used on wet or dry leather and will not over soften.
