I needed to replace my W730 shoes from New Balance as the mesh outsole was cracked and that model is getting hard to find.  I wasn't sure about getting a "trail" shoe but I loved the funky colors and these are fantastic.  The "trail" sole is not as pronounced as I feared it would be, and still very light and flexible.  I have taken them on the road and the treadmill for about 20 miles now.  I had no sizing issues, ordered my regular NB size (11B) and they fit great, roomy enough in the toe for some jogging.  I am thinking about a second pair in case they discontinue these out from under me as well.
