I am seeing that I tend to put 4 and 5 stars on most purchases, but I think it's just because I research what I want before I buy.  I am a huge Merrell fan, I've purchased at least 15 pairs of shoes.  They all fit my feet perfect, except these.  These have pads just above the heel to lock the shoe on to your foot a little more snugly I think, which I love.  However, they push your feet forward in the shoe a little more I think which makes my toes a little too far forward for my liking.  Or maybe they just fit smaller in general?  I would go up a half size next time though.  Incredibly comfortable running shoe though.
