Without a doubt, Linda's favorite footwear is Crocs. She has five pairs, each a different color. She wears them everywhere, inside and out. When she loves something as much as she loves her shoes, she wants to share the experience. I will occasionally slip on her Crocs to run outside, but Matt's feet don't fit. Even if they did, it would take a significant amount of money or Legos to convince him to wear holey, rubber clogs.
In Vegas, however, there is a an outlet mall with a Crocs store. Linda saw the chance to share her love of Crocs with her nephew. It worked.
