As the United States Marine Corps transitioned from its utility uniform to the MCCUU, they discarded shined black combat boots, and switched to more functional tan rough-out (non-shine) combat boots, with either hot weather or temperate weather versions. The standard-issue boot is the Belleville 500 Waterproof USMC combat Mermaid Shiny Zentai boot. Commercial versions of this boot are authorized without limitation other than they must be at least 8 inches in height and bear the Eagle, Globe, and Anchor on the outer heel of each boot.

The United States Army followed suit in 2002 with the introduction of the Army Combat Uniform, which also Sleeveless Leotard Metallic switched to tan rough-out combat boots, called the Army Combat Boot, and moisture wicking socks. Commercial versions of this boot are authorized without limitation other than they must be at least 8 inches in height and are no longer authorized to have a ‘shoe-like’ appearance.^[19] Two versions exist, a 2.5 lb temperate weather boot, and a 2 lb hot weather (desert) boot. Current manufacturers are Altama, Bates, Belleville Shoe, McRae, Rocky, Warson Brands/Converse Shiny Metallic Pants and Wellco.

The US Air Force uses a foliage green suede combat boot with its Airman Battle Uniform, although a tan version is authorized until 2011, when the green boot will become mandatory.
