Article in English: While it’s possible to waterproof just about any kind of shoe, you’ll get the best results with a more absorbent fabric. The wax you’ll be using will settle nicely into the woven fibers of fabric shoes. On materials like leather or synthetics, it will simply form a coat on the surface which is likely to wear off much faster. Canvas, hemp, suede, and other textured materials will make the best candidates for waterproofing. There are many different brands and styles to choose from, but they all do essentially the same thing. The most important ingredients you're looking for are silicone or acrylic polymers, which help block water and prevent mold, mildew, and general water-related deterioration. Waterproofing sprays can be found in most shoe stores, as well as shops that specialize in outdoor clothing and equipment. Hold the can 6–8 inches (15–20 cm) away from the shoe and mist on a light, even coating. Make sure you cover every part of the shoe where moisture might get in, including the seam where the upper connects to the outsole. Don't saturate it. Instead, look for the spray to just glisten once it's settled on the surface.  Hang up the shoe if possible This will allow you to accurately target the top half of the shoe without accidentally spraying your hand. To decrease your exposure to noxious fumes, work in a well-ventilated area. Outdoors is ideal, but if that isn't an option, you can also turn on the overhead fan. It may take two or more coats to make materials with irregular textures like suede or nubuck fully water-resistant. Go over the entire shoe lightly. Try not to use so much pressure that you soak up the wet waterproofing spray—a few quick dabs will do.  Avoid paper towels. The shedding fibers will get trapped in the sticky spray, effectively becoming a part of the material. Be sure to remove as much of the spray as you can from the surrounding outsole, as well as accents like zippers, eyelets, and rubberized detailing. Most sprays will dry to the touch within 20-30 minutes, but for guaranteed...
