Do not order shoes from catalogs and assume that they will look like the picture. They may look like the picture, of course, but they may also make your calves look like Washington crossing the Delaware. You have too many pairs of frumpy Aerosoles collecting frumpy dust in the frumpiest corner of your closet not to have gotten the picture by now. It's a goddamn swim fin. You cannot predict how a shoe will behave.
Cost is no predictor of a shoe's quality, or comfort.
You have no way of knowing. Ten dollars, two hundred dollars there's no guarantee. Carry extra Band-Aids. Maybe I could sue Kenneth Cole. Tips for happy feet.
