Exactly, Weiss is able to use her Glyphs to launch herself in one direction, but that involves the use of her Semblance. She has also used some kind of lunge attack that sort of defies the laws of physics. I mean she doesn't run a lot, but seems to glide across long distances, which is weird. I don't think this is a Dust ability because during her fight with the Beowolf, her rapier shifts to a fire setting. She also uses this during her fight with the Nevermore, gliding across a long distance before jumping up and freezing it.

There is one big problem however. During her fight with the Boarbatusk, she is disarmed and her sword is sent across the room. She then runs to retrieve it instead of gliding over which would seem to be the faster option. There is also this weird sound effect that appears whenever Weiss uses that glide move. So it could be tied to her weapon in some way, like a type of Dust that is always active instead of having to shift to it.
