Maintaining and looking after your patent leather shoes is easy, but they must be cared for differently than ordinary leather shoes. This is primarily because patent leather is coated with an additional high gloss finish. Since the appeal of patent shoes is its glossy finish, you'll want to keep them looking their best, through routine cleaning and shining.
Fortunately, patent leather doesn't require waterproofing. However, patent leather can dry and crack over time. Treat with a shoe care product designed for patent shoe maintenance that cleans, adds high gloss, and increase resistance to cracking.
