Best shoes for road running

Thanks so much everyone for all your advice - was absolutely spot on! I went into my local running shoe shop today and got video analysis done while running on treadmill. Turns out I over pronate so have been running in completely the wrong type of shoe for me! Ended up purchasing a pair of brooks adrenaline GTS 12. Yet to try them but hope they will work for me!
Just a query... Am I likely to get any pain while my legs/feet are getting used to running in the correct position in the new shoes?
