Fleet Footed is a passive core rogue ability learned at level 62. It increases the rogue's movement speed by 15%, but does not stack with other movement speed increasing effects.
This can actually be considered a DPS increase. The less time spent running away from fire, poison, oozes, or other unhealthy stuff, the more time spent attacking.

- Patch 2.3.0 (13-Nov-2007): Now increases movement speed by 8/15%, up from 4/8%.
