Crocs come in several colors, but if you really want to jazz them up, think Jibbitz. These charm-like accessories pop into the ventilation holes of the iconic shoes. You can show you’re a fan of Mickey Mouse, create a daisy chain across your feet or spell out your name with the whimsical adornments. Since debuting in 2005, Jibbitz have exploded in popularity. “Consumers loved the concept of expressing their individuality through the hundreds of Jibbitz charms available,” said a Crocs spokeswoman.
