Watch the Repel water repellant spray tutorial
The shoes should be clean and dry prior to application. Hold bottle upright 6″ to 8” from shoe and spray evenly, covering the entire area of the shoe. Do not oversaturate. Use a cloth to dab and soak up any excess product. Allow to completely dry/cure for 24 hours or more. After the first coat has dried, repeat steps and apply a second coat. Before exposing to liquid, make sure shoes have completely dried.
Keep in mind that no product can make your shoes fully waterproof. Given enough water, they’ll eventually soak through. However, you can achieve a strong water barrier, which should be enough to keep your feet dry in everyday conditions.
Repel also acts as a shoe protectant spray, keeping dirt and dust from attaching and settling into your sneakers. It comes in a non-aerosol can that sprays a continuous fine mist, and it’s PFAS-free, so you don’t have to worry about breathing in any toxic “forever” chemicals.
Tip: The longer you allow Repel to cure, the stronger the repellency.
