Delta V jump-boots

The Delta V jump-boots are a UAC-engineered device in Doom (2016) which can be acquired by the marine and used along with his Praetor suit. These boots enable a second thruster-based mid-air jump to be performed, greatly increasing the marine's maximum jumping distance and height. The boots are acquired near the entrance to the Argent Energy Tower, and are necessary for further progression in the game beyond that point.

Trivia
The Delta V jump-boots have the same mechanics as the space jump boots in the Metroid Prime series of games.
