The Vietnam-era jungle boots were quite successful. They went through minor 'improvements' since 1962 and used in large numbers by troops in the Republic. Jungle boots were the standard combat footwear for mild weather for decades following Vietnam. The last nomenclature for jungle boots was 'Boot, Hot Weather, Type I, Black, Hot-Wet', and uses either OG107 green or black for the nylon sections of the upper. In addition, the 'Mod 2' boot is identical except with tan color for the leather and the nylon, eliminating the protective steel plate because of its reliability as a conductor of heat in hot sand and vent eyelets because they allow sand in. The US military jungle boot helped influence the design of the notorious Desert Combat Footwear of the Americans next series of wars, Operation Desert Storm in 1991, Operation Enduring Freedom in Afghanistan in 2001, and Operation Iraqi Freedom in 2003. Despite the introduction of the desert boot at the time of Operation Desert Storm, many troopers used jungle boots because the 'brass' -- including the aforementioned Colin Powell -- lacked the planning ability to provide enough desert boots to issue to all personnel in the Middle East at the time, which led to many American soldiers and Marines to invade the desert wearing jungle boots and leather combat boots. Compounding the lack of planning, during Operation Enduring Freedom, American troopers used black jungle boots and black leather speed-lace combat footwear alongside the newer desert footwear in Afghanistan during the early 2000s.
