What is "jump boot"

n. A type of combat boot used by paratroopers assigned to parachute units, designed to be fully laced and to give extra support to the ankle.

Jump boots are standard footgear for Paratroopers and Airborne Forces featuring calf-length lacing and rigid toe caps. The style is a type of combat boot and versions were developed in many countries simultaneously with the adoption of airborne infantry forces during World War II. Modern jump boots are earned in some countries and therefore have become a mark of achievement and distinction, mainly worn as dress and parade boots. The uppers are generally made of smooth black leather with toe-caps and heel counters that accept a high polish (" spit-shine" or "spittle-shine"). It is also a paratrooper tradition to lace jump boots in a ladder or cobweb style which increases ankle support during a parachute jump,
