Editing Jump boot (section)

==Description==
Although there is considerable variation in the features of modern jump boots, an example of the defining characteristics can be found in the US M1942 "Boots, Parachute Jumper" (as popularized by the Corcoran Boot Company during World War II) are extended lacing from the instep to the calf and rigid, reinforced toe caps;<ref>Lemons, Charles. "Uniforms of the US Army Ground Forces 1939-1945, Volume 6, Footwear." {{ISBN|9781329217898}}. p62.</ref> these features were intended to give greater support to the wearer's ankles and toes during the rough landings routinely experienced by [[paratroopers]]. The most common US combat boots of the World War II era (the M1939 "Shoes, Service, Composition Sole") had non-reinforced uppers and only laced to just above the ankle, requiring the use of separate [[leggings]] or [[puttee]]s to provide support and prevent mud and dirt from entering the boot. Although less flexible than the lighter standard issue boot—and therefore often less comfortable when [[marching]], especially when cold or not well broken in—such specially reinforced footwear was seen as a practical necessity, as upwards of 30% of paratroopers were expected to suffer lower extremity injuries during a combat jump. Leggings were also considered to present a risk of entanglement with [[parachute]] risers.
