I use an off road pedal (shimano SPD) because road shoes arer DEADLY.
If you walk at all off the bike, the hard soles of the road shoes are slippery, they were not made to walk in.
MTB shoes were. You have to be careful though and make sure you get shoes with a stiff insole or you lose the advantage of clipless pedals ( I have Sidi Dominators. Don't try them on unless you can afford them. After I tried them I couldn't find any others as comfortable, so I ended up spending WAY more on shes than I wanted to.
