So I work in the Federal Building. I have to go through a metal detector every day. Usually no problems. Now when I go through the guards look confused and wand me every time. When they move the wand to the floor (shoe) it goes off. I've taken every item off my body. Have you guys known this to happen with good shoes. The construction is similar to Allen Edmunds etc, with the Goodyear Welt and replaceable heel.
