Last time I flew out of Frankfurt a few weeks ago, everyone on flights to the USA and Britain were being subjected to two security checks. Once when going airside initially and then another between the duty free and gate area.
Everyone who was wearing boots (not shoes) was having to remove them at the second check and have them passed through the scanner. I was chatting to the guy who was searching me while I was standing there in my socks, as my boots were being passed through the scanner three times and asked him why I had to take my boots off "Because they're boots" was the reply.
Now admittedly, I am only humble SLF, but why does it only pose a problem if you are flying to the USA or Britain? If it is so important to search footwear, why is it not done when flying to all destinations?
The way things are going, no one will be able to take anything with them when they fly.
