They are… But not really. The machine will flag you if you are going through with your shoes on and something is off about them. The only thing that’s different is it is easier to swab them if they think something may be off about them.
Which if you went through the body scanner and they thought something was off, they are going to ask you to step aside and remove them to be swabbed.
(Hence why anyone who applies for TSA pre check, could already keep their shoes on)
My guy. The type of xray they scan your bags with are not what they scan you with.
The reason they swab shoes is not to detect explosives. It’s to detect drugs. If you take hard drugs, or swallow bags, they can often see traces of it in your sweat. And shoes are a fantastic source of sweat.
The thing your personal items go through is an x-ray machine.
The little metal detector wands are to find a more precise hit on what is setting the first metal detector off, in case you are trying to hide something on your person.
So what your saying is scanning the shoes would have made no difference?
I’m saying the exact opposite.
The scanner you put your bags, electronics, jackets, and shoes on. Are different than the scanner you walk through.
That’s why they ask you to put your shoes there.

Both are x-ray machines
Edit. Sorry not always x-rays. Millimeter waves that can even see tumors… It isn’t just metal
