Yeah I've seen those. I think.... I know I've seen what looks like that. But if the technology inside is updated I can't say I know. Never had a problem with my balls being too warm in them. And I can't recall ever having my shoes on inside. Always had to put them aside. But that could easily just be airport policy at the time.

Anyhow... what irked me was the post acting like scanning shoes was some fake phony security scam. Almost every single airline and airport policy is there for a reason.

E.g. after the Lockerby tragedy. Airlines had to make sure that every single bag has a passenger that is on board the plane. As someone had checked in a bag with explosives, and then never boarded himself.
