I have a pair of socks that I call my “security socks” not because they make me feel secure, but because I wear them to go through airport security if I’m wearing flats. (Bonus: they keep my feet warm if I’m sitting in an exit row.) They are easy to slip on and have cute duck faces on them.
I get really grossed out when people go through security barefoot. Ewwwwwwww. Do yourself a favour, avoid weird foot diseases, and bring your own pair of security socks.
