This bill mandates that the Secretary of Defense issue regulations within two years, requiring that optional combat boots worn by members of the Armed Forces as part of a required uniform be entirely manufactured in the United States . This includes ensuring that all materials are grown, reprocessed, reused, or produced domestically, and all components are manufactured in the U.S. from such materials. The legislation defines "optional combat boots" as those not furnished by the Secretary of Defense. It establishes two key exemptions: one allows a Secretary concerned to waive the prohibition for specific-use boots where domestic availability is an issue, and another exempts boots that are medically necessary for a service member's unique physiological needs.
