Fabric & Leather Proof Sponge Easy to use water-based waterproofing for fabric and leather footwear. Waterproofs, maintains support, texture and breathability of all combination footwear. How Nikwax Fabric & Leather Proof™ protects. Nikwax Fabric & Leather Proof™ is easy and quick to apply; either spray or sponge on to wet boots. Nikwax Fabric & Leather Proof™ provides highly Durable Water Repellency (DWR) which develops on air drying. It leaves a flexible water repellent treatment on individual fibres of fabric and leather. This allows moisture vapour to pass through, maintaining breathability and keeping your feet dry. Nikwax Fabric & Leather Proof™ has been specifically designed and optimised for fabric and leather combination footwear. Like all Nikwax products, Nikwax Fabric & Leather Proof™ is safe to use.
