CartoonhavPrinted flip-flops are great in theory, but they do tend to lose their appeal when the pattern wears off the first day you wear them. But this is where Havaianas come in. Not only are the famous brazillian best-sellers the comfiest flip-flops in the world, but the print stays pristine months after you've bought them (I speak from experience). Take full advantage with these cartoon print ones ($13.49 / £6.95 from the fabulous Igapost).
