What is shoe metal shank?

A shoe metal shank is a thin piece of metal that is embedded into the sole of a shoe, beneath the arch area. It runs from the heel to the ball of the foot and provides support and stability to the shoe. The shank can be made of various materials such as steel, fiberglass, or rigid composites.

The purpose of a metal shank in a shoe is to distribute weight evenly across the foot, to reduce stress on the arch, and to prevent the sole from collapsing. It also adds durability and longevity to the shoe, as it prevents the sole from wearing out too quickly.

Shoes with metal shanks are particularly beneficial for people with flat feet, high arches, or other foot conditions that require additional support. They are also often used in work boots and hiking shoes, as they provide added stability and protection for the foot.

It's important to note that a metal shank can add weight to a shoe, which may not be desirable for some people. Additionally, shoes with metal shanks may not be suitable for certain activities such as running or aerobics, where flexibility and lightness are important.
