Bring one with you. Two of my friends who I visit regularly who request I remove my shoes now have a shoe horn by their shoe rack because I asked that they provide it for me. That's a must. I often have a shoe horn in my bad/briefcase just in case. I would assume that everyone here brings a shoehorn with them to the airport. I bring plastic so it's easier to go through the metal detector.
