Airline passengers may want to choose shoes that are easy to take off. New guidelines were released by the transportation security administration this week.
Airports cannot require everyone to go through security in their socks, but the guidelines encourage passengers to remove certain kinds of shoes to avoid setting off detectors and slowing down lines.
"If you have shoes that are likely to have metal in them, like women's shoes where there is a metal shank that keeps that form, or dress shoes very often have a steel shank in there, we'll say yes, in all likelihood that will alarm the detector, why don't you take those off and speed up the process," says Quinten Johnson.
Boots and thick-soled sneakers are also bound to cause trouble. Passengers can initially refuse to remove their shoes, but if they set off metal detectors they'll have to do it anyway.
