text: I own 2 pairs of the New Balance WT610V3 and love them but they are discontinued.  This V4 version is very different.  The sole is not contoured at the arch and therefore does not have as much flexibility. The shoe feels flat and boxy to walk in which will not help with trail terrain.  Also, the shoe runs short and too wide - creative lacing does not help this issue. Please go back to your V3 version, New Balance.  I returned them and am now shopping other brands.
