You can never have too many shoes-and people judge you based on every single pair.

In a study published in Journal of Research in Personality, researchers found that people could accurately guess a stranger's age, gender, and income simply by looking at what was on their feet. They also associated certain personality traits with different shoes. More masculine-looking pairs were thought to be worn by less agreeable people, while stylish or attractive shoes were assumed to be donned by rich, conscientious folks. And people rocking those ankle boots that are so in right now came across as aggressive.

So what do our shoes say about us?

Can you guess which shoe is Ryan's? Shannon's? Beaker's?
