Speedplays are definitely ROAD cleats. That said, I routinely walk through gravel parking lots, or into the woods for a pee break without problems. Mud and snow are definite no-nos, but that's what cleat covers are for - they fit in your jersey pocket and keep your cleats clean.
Speedplay also makes a MTB/CX cpedal system designed for mud/dirt/snow/etc - SYZR. They supposedly have the same float as Speedplay road pedals, but in a recessed pedal so they're suitable for off road use.
