Removing shoes at the airport is normal. This started after a passenger tried to hide explosives in his shoes in 2001.

Checking shoes is important for safety, but it can be annoying for people on holiday.

Walking in socks or bare feet can be uncomfortable and dirty. Many people walk through the area, making it dirty.

A pilot's wife, Laurie, has helpful advice. She posts useful travel tips on Instagram.

Laurie gives two tips for when you have to remove your shoes at the airport.

Most people cannot shower at the airport, and using a sink may look strange.

You can still clean up with antibacterial wipes in your hand luggage.

You can quickly clean your feet with antibacterial wipes if you have to walk barefoot.

Antibacterial wipes are also useful for other things. You can use them to clean surfaces on the plane.

It's a good idea to clean the airplane window before resting against it.

You should also clean other surfaces like TV screens and tray tables.

Walking on a dirty floor can be unpleasant, even with socks. It's not good if you have to wear the same socks all day.

Laurie suggests wearing old socks through security and throwing them away.

If you can't throw them away, bring a spare pair and a plastic bag to change into clean socks.
