Spray waterproofing spray on your shoes. Choose a pair of waterproof textile-based sneakers. While it is feasible to waterproof almost any type of shoe, the best results will come from a more absorbent fabric. The wax you'll use will easily penetrate the woven threads of fabric shoes. However, you can also waterproof leather shoes by applying a thin coat of wax. Waxes for waterproofing fabrics are available in all-purpose and sports-specific varieties. They work by preventing water from entering the shoe through the sole or uppers. Some waxy products contain chemicals that break down over time, releasing small amounts of formaldehyde into the air. These compounds are considered harmless, but some people may still have concerns about using products with formalin in them. Sports-specific waxes are designed to withstand heavy use and remain effective for longer periods of time. Waterproof your shoes so you don't get wet when it rains or springs a leak if you walk in deep mud or puddles. This will help keep bacteria away from your feet too! Use a fine-tipped brush to apply the wax. Make sure not to apply the product to any area where it might be visible, such as around the laces or tabs. Allow the product to dry before wearing your new shoes. You can speed up the process by placing them in a warm oven (150 degrees F) for 10 minutes before putting them on.
