I often like to wear my gym shoes mismatched.

I have like four pairs of Converse all in different colors and I like to wear two different colors at a time. But I almost always use the same two, so I have one of each colors that's dirty and beat up, and one that's clean and looks new. So on the occasion that I wear them matched up as a set, it looks even weirder cos I have two shoes of the same color but one is dirty and worn, and the other is pristine. People often ask me why one of my shoes is so much more worn than the other, and my response is "That's my ass kicking foot."
