TREATMENT OF FABRIC, NABUK AND SUEDE – We recommend the following special treatment for models made of Fabric, Nubuk and Suede with GORE-TEX® or Cambrelle® linings. In this case we suggest using special products, that guarantee the simultaneous waterproofing of leather and nylon. We recommend something specific like Imperwass that we tested and sell with the brand name CRISPI®. It is available from our distributors and in specialized shops. Oil and waterproof spray for leather, suede and cloth it does not stain neither changes the colour. These products, besides improving the waterproofing characteristics of the boot, don’t affect at all the other technical features, such as the breathability of GORE-TEX®.
