You're right, it's on all three body types. So I guess it's intentional? But it seems weird that there are already path auras in the game and there's no way to turn the glow off on the boots. Also I know from playing with them that the glow is not just when running, any movement including flying causes it to kick in.
Ah well, maybe not a bug but perhaps consider a toggle on the these boots to turn off the aura. What forum would that request go under?
