If the shoe fits you’re lucky because the fact is many of us are still pouring our feet into the same size shoes we wore in college or even high school. According to a video report from the style editors at the Wall Street Journal, you should have your foot measured at least once a year. Ill-fitting shoes cause callouses, bunions and hammer toes too. Of course shoe styles contribute to that too, and ballet flats can be just as damaging as stiletto heels. Watch the video now, and start measuring.
