The main purpose of this legislation is to ensure that optional combat boots worn by members of the Armed Forces are made in the United States. The objective is to promote domestic manufacturing and ensure that the materials used in these boots are sourced from within the country. The key provisions of the legislation require the Secretary of Defense to establish regulations that prohibit members of the Armed Forces from wearing optional combat boots unless they are entirely made in the United States. This includes both the manufacturing of the boots and the materials used to create them.
