I know that shoes are HIGHLY personal, but worth poking the collective anyway.

I like Sidi shoes because they run narrow. I actually loved their "S" which are extra narrow but they don't make them anymore.

I have been using Genius 7 for the past few years, and they are starting to wear out. I am considering buying a new pair but also considering the Genius 10.

Anyone use both to comment on the differences in fit or quality?? I know the 10 uses a boa instead of velcro, which I am willing to consider, but I am wondering if any other obvious differences you noticed.
