This is a well constructed, very sturdy shoe.  If the fit of these works for you, they are excellent.  Unfortunately for me, New Balance has changed the fit from that of the M977GT.

New Balance says these shoes have exactly the same last (WOL-01) as the M977GT.  That may be true.  Nevertheless, there are styling differences to the front toe that make it fit differently.  I liked the M977GT so much that I bought 2 extra pairs.  I was thinking of buying more, but the M977GT is no longer available in my size anywhere.  I decided to try the M978GT after talking with New Balance.  I just received a pair of these.  When they felt tighter in the front toe, I pulled out my last (sigh) new pair of M977GTs to compare.  They have changed the styling; it does fit tighter in the front toe.  The last may be the same, but the fit is not.  Perhaps this is due to the difference in construction.  Whatever it is, they are not as comfortable for me.
