Pey'j originally created the Jet-Boots as a new means of personal transportation, but don't w
ork as planned due to 'bugs' that Pey'j still needs to fix, however it turns out they are more useful as they are.

Pey'j relies mostly on the Jet-Boots he created to execute powerful ground pounds. This causes enemies to bump into the air, making them more vulnerable to Jade's attacks. The Jet-Boots are powered with home-made bio-carbonate, stored in a pocket of pressurized methane on the back of his pants. On the soles of his shoes are two turbo-reactors that activate whenever he contracts his abdominal muscles.

Pey'j mentions that the Jet-Boots are the result of a life's work and took two years to build and finalize.
