I figured they just work on pure 'force', not using air specifically as a medium. They still work while flat on the ground, unless I'm mistaken, with
no air to exert force on below them. If that is the case, the sword will receive the same thrust as the air around it. Regardless of how it is, air or just force, the boot
should be going
away from the sword, not following it down.
