I have been wearing Brooks Ravenna for so long, I can't remember when I bought my first pair. I used to wear Nike, but these are so much better, I never went back.  The Ravenna has changed a few times with each generation and not always for the better.  With each change, there was an adjustment.  However, the Ravenna 8 is awesome!  No break-in period.  They are very lightweight and great for my ankle pronation.  I usually wear a size 8 shoe, but as in all running shoes I get an 8.5 for a little extra toe room.  If you do distance running, your toes will thank you for the extra half size.  No black toenails for me!
