The last time I took off my shoes to get through airline security, I fell and some women barged ahead of my husband and just stepped right over me, not even bothering to ask if I was OK.
Now, I just pull up my pant legs to show them my leg braces and tell them I cannot walk without my shoes. They have me step aside where I can be wanded, which only takes a couple of minutes, and then I'm on my way.
