Crocs are ugly.
To this day, I am surprised that people are so blinded to the fact that they are hideous. These will eventually go by the wayside, just like fanny packs and tight rolled jeans. Yes, I know people still wear fanny packs... but they always agree that it is not on fashionable terms. With crocs they are still attempting to be "trendy."
Wear a great pair of tennis shoes. Maybe then you won't look back on the pics in 20 years and say "what was I thinking!" (although, those pics are kinda fun too).
