No they are not. I went to the ECCO store at Mall of America in MSP and specifically asked for "airport friendly" shoes. The sales dude talked about all his United pilot buddies who swore by Eccos so I dropped a $buck 30 on his recommendation and proceeded through security only to hear the dreaded beep. I was pretty angry about the whole thing as he assured me they were safe. I brought them back and got these:

ECCO Helsinki Slip On Mens Dress Shoes

I have tried just about every brand over the years and I am most satisfied with these.
