At the same time, the range of products offered by Nikwax grew at a rapid rate as Nick realised a need not only for proofing shoes, but all kinds of apparel, including ropes, tents, clothes, shoes and goggles. Nick wanted to keep walkers and adventurers comfortable all over, not just in their shoes. Nikwax treatments work by coating the fibres. They bond to anything that is not water-repellent, but leave the spaces between fibres open and breathable. That means they’re very effective with lots of different fabrics including cotton, suede, nubuck and wool.
