Protection from the elements (water, mud, dust, snow or salt)
Use Ralyn Aquatec. Spray over entire surface. Let dry before wearing outdoors. Also consider Ralyn Mink Oil to help waterproof and preserve your shoes, however it may darken lighter shades of leathers. For lighter leather colors use Ralyn Liquid Silicon to waterproof, it will not darken the leather.
Use Ralyn Suede/Nubuck Aquatec to protect sueded leather from the elements. To clean use a suede eraser (found in Ralyn Suede Care Kit). You can also use Ralyn Suede Cleaner with built-in brush cap. Use a suede brush to renew the suede leather
