An easy to use water based waterproofing Nikwax Nubuck & Suede Proof™ has been specifically designed and optimized for nubuck and suede combination footwear and, unlike other waterproofing possibilities, will maintain the texture of the materials. Wax based waterproofing will flatten the nap on your blue suede shoes, and that would just ruin things. But when you’re dancing in your blue suede shoes, or working in your boots, your socks draw moisture away from your feet, keeping them dry, and the moisture evaporates through the breathability of the leathers. If your shoes are absorbing water, or wetting out, their breathability is reduced, with moisture vapor unable to escape. Your feet will feel clammy and damp, and it is time to clean the dirt off those shoes and lay a little Nikwax Nubuck & Suede Proof™ on them for a Durable Water Repellency (DWR) finish which prevents water absorption, to keep them breathable and your feet dry and comfortable. So if you do anything to your blue suede shoes, maintain their flexibility and water resistance with regular cleaning and a little Suede Proof, and go cat go!
