I've been purchasing New Balance sneakers for more than decade.  I chose New Balance because they have a better selection than others in the EEEE width.  I usually get them at a local sporting store.  They were out, so I tried on Amazon.  Amazon had better prices and a better selection.  I tried the MX608 this time, which is one I have not seen at my local store.  It fits and performs like other New Balances I have owned, with one major exception -- the bottom, back of the heel is attached poorly.  The bottom 1/4 of the heel has become unattached on my left shoe.  The bottom 1/8 of the heel has become unattached on the other.  I expect the left is worse than the right because it my clutch pedal foot.  The heel started to come ofter after only ~1 month and has continually grown worse during the 4 months since then.  This has never happened with any other New Balance shoe I have owned. I'd write it off as a rare anomaly if it was only on one shoe, but since it happened on both, I believe it is a design problem and will likely happen to others.
