Metal used in shoes typically serves what purpose?

Metal components in shoes primarily serve the purpose of shanks. A shank is a supportive structure placed between the insole and the outsole of a shoe, enhancing stability and rigidity. This is particularly important in therapeutic shoes, as it helps distribute weight evenly and provides the necessary support for individuals with foot conditions or who require additional stability.

While decoration can be a secondary use of metal in some fashion-forward designs, its main functional role in therapeutic footwear is to aid in the shoe's structural integrity. Padding, typically made from softer materials, is employed to provide comfort and cushioning rather than structural support. Therefore, it is the shank that plays a pivotal role in ensuring the shoe can accommodate the specific needs of users, making it essential for both safety and comfort in footwear design.
