Ultra runners know that there's a fine line between too much and too little protection when you're grinding out a long run. The New Balance Men's MT1210 NBX Trail Running Shoe strikes this balance and then melts away under your foot so you can concentrate on the run, and only the run. A medial post and flexible overlays offer more support than many of New Balance's lightweight minimalist options, while lightweight cushioning and moderate heel offset help you feel light on your toes in technical terrain. Ultra courses are long and the terrain unpredictable, so this shoe incorporates limited-seam construction to reduce blistering and a Vibram sole with bi-directional lugs to help you handle ascents and descents with equal confidence. As a final touch, New Balance's engineers widened the toebox of the 1210 to allow room for foot swell—a common byproduct of high-mileage running and an issue rarely addressed in even the highest-volume trail shoes.

  • Synthetic uppers keep this shoe lightweight and allow it to dry quickly on wet trails
  • Mesh upper panels help your foot stay cool in hot weather
  • Flexible overlays improve the support of the upper and lock your foot in place so there's no sliding or sloppiness to the fit
  • Debris-free construction incorporates a lightweight inner material that shields the foot from dust, dirt, and debris that could cause blisters or discomfort
  • Limited-Seam Internal Construction positions seams in a way that reduces the opportunity for chafing that could cause blisters
  • Moderate 8mm drop (heel-forefoot offset) offers a balance between the feeling of a traditional shoe and the progressive design of a lower-drop style of shoe
  • Moderate heel drop allows you to easily transition between heel, mid, or forefoot striking styles depending on your preference
  • Medial post provides the arch support needed for long-distance and ultra-distance running
  • Vibram outsole is highly durable, and it uses a bi-directional lug pattern to create immense traction for ascending and descending

Best I've Ever Owned

  • Familiarity:I've used it several times
  • Fit:Runs large

I originally bought the Brooks Cascadia 8's-twice, the shoestring holders broke both times. I couldn't ever get them tight enough on my foot for worry of breaking them for a third time, so I returned them and bought the NB's, which my local running shoe dealer told me they are practically the same shoe. It's taken me two runs in these to really fit in to them, but now that I have, these shoes have given me back my ability to run long, and on consecutive days. Had a pair of Addidas Kanadia's, and they absolutely killed my feet, plus I over-pronate badly-both issues resolved. If you don't run long, order 1/2 size smaller.

Glad to hear they helped the over-pronating issue. I have the more low-pro New Balance MT1010s and loved them at first, but had some over-pronating problems recently and tore them up last weekend so I'm starting to look for something else.

After your comment these seem like a replacement.
