Wow... Sidis are too wide?

I have a wide foot (actually kind of narrow at the heel) and ended up having to buy men's wide width when I got my Sidis. The guy in the LBS said the wide weren't wide enough for his feet.

I know some of the Sidis come in narrow sizes. Have you been able to try those out?

I also have a pair of Specialized WSD mtb shoes. I think they may be the same width, if not wider, than my Sidi road shoes.
