Those who like to carry a pistol in their shoe beware.
IDOI has technology that will detect metal inside shoes, hence if one is being shoe-scanned, one could be detected.
Feel free however to carry plastic explosives inside your shoes because MagShoe does not detect plastic explosives.
It's like making a fork but leaving off the tines, maybe it could still be used as a crippled flat spoon, but how will one get any use out of that?
Thoughts?
Disclaimer: I do not advocate carrying guns or explosives inside of shoes, I merely report on preposterous ideas that seem to sell to investors.
