Many people have asked me,"how they should keep their Sperry's clean"? The answer is very simple, you don't. They were designed as a water/boat shoe and conditioned to be worn. The basic principle is the more beat up your Sperry's are, the more money you have...lol. If you don't believe me just pay attention the next time you see a Harvard or trust fund kid wearing a pair. They will definitely be "WORN".
