Everyone in the world knows somebody who wears Crocs, and they always say the same thing: "They're so comfortable!" You can explain to them that there are plenty of other shoes made for being on your feet all day that don't look like blocks of brightly-colored, plastic Swiss cheese, but there's no reasoning with fans of Crocs. Comfort is all they care about and that's why they love their ugly shoes (Yes, they come in styles that barely look like Crocs now, but still. It's the principle). But guess what? While they may initially feel comfortable, it turns out that Crocs aren't actually all that good for your feet or body (reminder: toe shoes).
