3. Shoes That Are Difficult to Remove
We advise travelers to wear slip-on shoes in the airport security line. You’ll have to take your shoes off and put them in the screening bin before walking through the metal detector, and flyers fumbling with tangled laces or strappy sandals could hold up the line. Plus, if you’re in a hurry to catch your flight, slip-on shoes will be easy to put back on and thus will hasten your transit from the end of security to the terminal.
Note that children under the age of 12 and adults ages 75 and older may leave their shoes on during screening.
