Leg shackles are devices used to restrain a person's legs, typically made of metal. They consist of two rings that encircle the ankles, connected by a chain. Leg shackles are often used in law enforcement and correctional facilities to prevent escape and ensure the safety of both the individual and others. These restraints can also be found in historical contexts, such as during the transatlantic slave trade, where they were used to confine enslaved individuals. While leg shackles serve a security purpose, their use raises ethical concerns regarding human rights and the treatment of individuals in custody.
