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.
Footwear that rises to the ankle or higher; can be casual or dressy, practical or fashionable. Boots that are designed for protection from the elements may be made of a single, closely-stitched piece of leather, rubber, or other material to prevent the entry of water, mud or dirt. Other types of boots are sturdy in nature, intended for protection in wilderness or industrial settings. Fashionable boots for men and women may have all the variations seen in other shoe styles, including high heels, platforms, and lacings.
