You have an incredibly soft step, making it diffi cult to track or hear you.
You can walk without leaving behind any but the most subtle marks. The Survival DC to track you increases by 5 (or by 10 if you move at half speed to hide your trail; see the Track feat, page 101 of the Player's Handbook). You ignore any penalties on your Move Silently checks incurred by noisy or very noisy terrain (see the Move Silently skill description, page 79 of the Player's Handbook).
