Definitely not what I've come to expect from New Balance.  I wear a 12 AA and previously found New Balance sizes to be very good.  The New Balance site instructions state "This shoe runs true to size.  Order your regular athletic shoe size."  These shoes are off at least 1/2 size.  My toes hit the end and stressed the top fabric and caused pain.  Even though the shoe label was marked 12AA the width was more like a B width or wider.  Overall fit was not good and after wearing them for about an hour they felt downright uncomfortable.  They were laced loosely and still hurt the tops of my feet.  I've previously had 811 and 846 and those fit very well and were very comfortable, the 846 the most comfortable and supportive.  New Balance has a lemon with their 993, at least in my size 12AA.  From my experience I would not be happy to exchange them for a larger pair to fit my foot length.  Fortunately I never got out the door with mine on so I can return them in new condition.  If you decide to go ahead and try a pair because of New Balance's past reputation make sure you check them out well. But I would advise if you can find other shoes in your size you should avoid the 993.
