Ever since the lowly shoe became a legitimate security threat, bare feet have been on display at airports across the country. Last summer, even nylon sneakers and skin-baring sandals had to come off. Aside from frequent pedicures, how can you sail through screening points with your dignity—and feet—unscathed?• Most shoes are made with metal shanks, which set off detectors. Though wearing metal-free loafers will not guarantee that you avoid a shoe search, they won't trigger the alarms. Rockport, Taryn Rose, and Johnston & Murphy all have new lines with synthetic shanks. • Pack a plastic shoehorn for easy on-and-off. • Don't go sockless. "Unless you wear some kind of hosiery, you'll be at risk for contracting plantar warts or a fungal infection," says Dr. Steven Cohen, a dermatologist at New York's Mount Sinai Medical Center. If you aren't going to wear socks, slip Peds or the Gap's Not Socks into your carry-on.
