Waterproof Your Boots and Shoes - Spray some over the top of your shoes and boots. This Will act as a barrier to prevent water from penetrating it. Allow them to sit for about a day before wearing them in wet conditions.
Use Beeswax to Waterproof Canvas Shoes: I LOVE this one, especially for beach season or rainy season. You can use a bit of beeswax to waterproof your shoes! Just rub the wax onto your shoes, blow-dry to seal, and you’re done.
