Wear slip-on shoes when flying

Most airports still require you to remove your shoes at security. Even at airports that don’t require shoe removal, you may be delayed and asked to remove your shoes if they’re big or high enough to potentially conceal a weapon. Sneakers or slip-on shoes (mules, loafers, etc.) are your best bet. Flip-flops seem even better, but keep in mind that you’ll end up walking around barefoot on dirty floors.
