I don’t know about you, but I tend to look at people’s shoes a lot, especially when I travel. And over the course of the past year, there was a particular shoe style I kept seeing on people’s feet. If you’re thinking flip-flops, we’re on the same page. What kills me is that there are so many shoe trends out there that are just as easy and comfortable as flip-flops but are significantly more protective of your feet.

I wanted to know how flip-flops rank on the airport practicality spectrum for travel shoes from the experts themselves, so I reached out to TSA spokesperson Lisa Farbstein and a flight attendant for a major airline. Farbstein pointed out that while you can certainly wear flip-flops to an airport, “They are thin-soled, [and] they still will need to be removed at the TSA checkpoint, which typically means bare feet on the floor.” So making the security process easier certainly isn’t a valid reason to wear them.

The flight attendant told me, “As flip-flops are great to slide on to head down to the pool, as a flight attendant, they are not my footwear of choice when exploring a new city. They offer no support, which is basically my worry.” I asked what she thought of wearing them to the airport and flying in them, to which she responded, “I mean it’s sort of gross. There are so many bacteria. Wearing flip-flops, you can get blisters and then bacteria can get into your feet.” Yikes, right?

Instead of flip-flops, here are six shoe styles that are much better options for the airport. See which celebs travel in them and shop the styles below.
