The shoes-off/shoes-on dance at TSA checkpoints will end soon. But there's a catch you need to know about. Here's what we know.

The Transportation Security Administration has relaxed one of its policies for boarding domestic flights. Passengers are no longer required to remove their shoes when processing through security lanes in U.S. airports.

Most passengers had been required to remove their footwear at checkpoints since 2006, a policy later eased only for members of trusted traveler programs.
