Shanks

In our industry, or more specifically in the footwear component sector, it is often said that steel sheets, also known as “shanks,” are indispensable. They represent an invisible yet resilient skeleton that supports the entire weight of the individual wearing the shoe.

This is an essential, highly technical role. Here are the technical specifications of our steel:
