Don't know about the highest rated, but I have a pair of Specialized Carbon Road shoes and they're really great. I tried many pairs before deciding on those. It's important to choose one that fits your feet and makes your comfortable.

I also have a pair of Louis-Garneau "touring" shoes, with recessed cleats (I keep my SPD-mountain pedals somewhere) and I intend to use them again for touring. But for strictly road, sports (not tourism) riding, the Specialized shoes are just great. Especially on climbs.
