I am currently using Shimano RT82 shoes with Shimano A600 pedals. The RT82 is a touring shoe that uses a recessed SPD cleat (walkable). They lock in solidly to the A600 which is a road pedal. The interface is as good as any look style cleat I have used. This setup gives me the best of both worlds - the RT82 sole is as stiff as any road shoe I have used, but allows me to walk easily. Pedal entry is as easy as any look compatible pedal I have used. The A600 is also reasonably lightweight at 286g.
