I wear size 9.5 in New Balance and 43 in Specialized shoes. The problem is that they keep changing the shoe lasts (molds???) so the width dramatically varies between different shoes in their line.
I bought a pair of Specialized Pro (one step below S-works) and they were **narrow** even in the wide sizing. Returned those and got the Comp (Carbon sole) in 43 normal and they are awesome.
