Last year when flying I wore some new sandals. I alerted through security and had to stand on some machine that tested them. They still weren’t happy and I had to take them off and put in a tray to go through the machine. Coming back into the UK I had to again take them off and put through the scanner machine on a tray.
I’m wanting to take them again this year. Same airport going and although not the same coming home it is the same country so probably same procedures.
I was thinking of taking them in my suitcase rather than wearing them. I assume that would be okay? I don’t know what set off all their protocols they do have a couple of metal buckles so I assume that’s it.
