If you are riding road, go with a good stiff road shoe. I like my Sidi Genius 4 Mega shoes and have a fairly wide foot. They are matched with Campy Pro-fit pedals. I wear a Euro 46 shoe. What I really like about the Genius 4 is the fact that it has two velcro closures (towards the toe) and one micro-adjusting (ala ski boots) strap over the instep. You can make nice adjustments to get it just right. I find that after I've pedaled for a few minutes I need to ratchet down the top strap.
