Lol--I'm the wrong guy to ask!
I use SPD M520 MTB pedals (on a road bike--the horror!!!) My shoes are Specialized Sport MTB.
Double-sided and a breeze to get in and out of. A decent amount of "float" in the cleat while it's engaged, too.
I like the MTB shoes because I can walk in them while I'm off the bike. Nice for those long rides where there's a break and/or I want to go into a convenience store mid-ride.
That said, I'm sure there are plenty of road shoes that are compatible with the SPD mountain cleats.
