How to make leather shoes waterproof?
assistant
To make leather shoes waterproof, first apply a waterproof spray or wax to the outside of the leather. Make sure to cover any seams and lightly work into the leather. Give the shoes at least 24 hours to dry before wearing them. For added protection, it is also a good idea to apply a waterproof sealant to any linings or sensitive areas of the shoes. This will create a barrier against water and potential staining.
