Aura being able to let you stick to surfaces isn't that remote; we've gotten shielding, super-senses, blocking damage from all kinds of attacks, etc etc

But I think the only one REALLY doing that in Episode 8 was Blake, when she ran straight up a 180 degree pillar. Otherwise, Ruby and Yang were using the recoil from their weapons to launch themselves in the opposite directions (ie up in general), and Weiss was using her runes (with full 'kick-off- ability). Still unrealistic by our physics, but not show-wise overall, I believe
