Flyers may no longer need to remove their shoes in order to pass through airport security, according to Secretary of Homeland Security Janet Napolitano.

In an interview with POLITICO's Mike Allen Tuesday morning, Napolitano said that the shoe-removal policy could soon be discarded as the Transportation Security Administration retools its screening procedures and adopts new technologies.

“We are moving towards an intelligence and risk-based approach to how we screen,” Napolitano told Allen. “I think one of the first things you will see over time is the ability to keep your shoes on."

However, Napolitano cautioned that one of the most maligned screening restrictions, the size limitation on liquids in carry-on luggage, would probably not be changed in the near future.

Last week, Napolitano said in a statement that there was no credible evidence to suggest an imminent terror attack, but cautioned citizens to be extra vigilant as the tenth anniversary of the September 11 attacks draws near.
