The Right Protectant for Your Shoes
Different weatherproofing products serve different purposes, so you should choose wisely. For example, if it is essential that your shoes are waterproof because you spend a lot of time in wet or messy conditions, and a pretty finish is not as is important, a beeswax product would be a better choice than a protective spray. Beeswax products form a protective layer over the surface of the shoe or boot instead of being absorbed into the leather. This provides a better barrier against water, but the additional layers can alter the appearance of the shoes. If the appearance of the shoe or boot is of more importance than the weatherproofing properties, a spray protectant should do the trick.
By providing a breathable barrier against mild to moderate wet conditions and dirt, this type of weatherproofing product is virtually invisible on your shoes or boots. Joe's Shoe Service sells a large variety of waterproofing products including those for smooth leather, suede or nubuck.
