I have to order 2A (narrow) in my brooks running shoes, my feet are narrow with high arches. I have had some luck inserting superfeet inserts green insoles into my pearl izumi to take up some room and create higher arch support. Good luck.
My feet are very narrow (even Sidis are too wide), and the Specialized Zante's are perfect for me. I also use custom orthotics to make it a little more fitting to my foot. https://www.strava.com/athletes/10327392
