While many leather shoes are highly water-resistant, saturation can damage leather shoes if not dealt with properly. This damage can include discolouration and deformation of the leather, cracking, splitting of the leather or mould growth. When leather shoes are saturated with water, the best way to avoid damaging the leather is to pat the boots dry and allow them to air out in a cool, dry place. It’s important to avoid using high temperatures or heat tools to dry out your shoes, as this may deform or crack the leather. Be sure to wait until your shoes are completely dry before wearing them again.
