This bill directs the Secretary of Defense to establish regulations within two years, prohibiting members of the Armed Forces from wearing optional combat boots as part of a required uniform unless they are entirely manufactured in the United States. The regulations specify that these boots must be made from materials grown, reprocessed, reused, or produced domestically, and their components must also be manufactured in the U.S. using such materials. The legislation defines "optional combat boots" as those not furnished by the Secretary of Defense. It includes an availability exemption , allowing a Secretary concerned to waive the prohibition if specific-use optional combat boots are not available from domestic sources. Additionally, a medical exemption permits the wearing of non-compliant boots if medically necessary for a service member's unique physiological needs.
