I wanted to wait until I had given these shoes a real trial on different surfaces. Now 175 miles in I feel like I can make an informed recommendation. Though I haven't ran on a truly rugged trail yet, I've ran on dirt, grass, pavement, sidewalk and woodchips and the shoes perform.  The fit was true right out of the box and there was no uncomfortable break-in period.  The materials hold up well under wet and snowy conditions and dry quickly to get right back after it. The ride is well cushioned and the outsole grippy.  These are my first New Balance but won't be the last. I need to check out the 880 road model.
