Airport Safe/Steel Free footwear refers to footwear made without the use of steel. In order to provide basic support and stability, shoes generally feature a metal plate called a shank, which is located within the sole and right below the arch. Airport Safe/Steel Free shoes replace this steel structure with a composite, non-metal shank that will not trigger metal detectors, yet still offers the same support.
