I was using SPD cleats and mountain bike/touring shoes on my road bike.
The reason for the touring shoes is that road shoes are all too narrow, including the supposedly roomy Carnac whats-its.
Now I've kept the same comfortable Shimano lace-up touring shoes but have switched to Speedplay Frog cleats and pedals. The Frog is the MTB version of Speedplay.
They cost about $129. They are very lightweight and can be lubricated without disassembling the pedal. They are very easy to get in and out of and the Frog cleats permit me to walk from the house to the garage without slipping down the back steps and breaking my neck.
I have a nice new pair of Wellgo WAM-R4, SPD-R pedals and cleats for sale, cheap, if anyone's interested. I tried to find road shoes to use with them and gave up.
REI sells a good-looking pair of Shimano touring shoes that have Velcro straps like a road shoe but might fit more comfortably. You could fit Frogs to them.
