***Update to previous review***  SO disappointed with these, worn for less than 25 miles and holes are already forming on the sides of the toe box...feel as though this was an utter waste of money. The toe box is a little narrower than I've experienced with my last 4 pairs of New Balance.  They are super soft, cushioned, and provide excellent traction on a variety of terrain.  I feel as though the outer construction may be a bit flimsier (with the benefit of making them much lighter) than past New Balance shoes so I am interested to see how they hold up in the rocky terrain they will be subjected to.
