Gotta give a thumbs up to Specialized on their shoes. Got a pair of Sworks road shoes this past spring, came from using Sidi. The built in forefoot wedge means I don't need the Big Meat wedges under my cleats anymore, which is the reason I got them.
For 100 bucks or less, all the shoes will be the same other than the forefoot wedge Specialized uses. Thas is the one feature that makes them stand out among the plethora of cycling shoes out there.
I will say the Sidi have a more comfortable upper, something about the material they use is just better for that glove like fit the Italian shoe makers are known for. If Sidi had the wedging built into the sole of the shoe, I would have gone with them, but sadly, they don't!
