    Good points for New Balance: the effect of Fresh Foam for those of you who are fans and the Vibram Megagrip.

  • 96 / 100 | Road Trail Run | | Level 5 expert

    I would recommend the Hierro v2 for all day training runs in a wide variety of conditions/terrain, ultra races, or for those looking for one shoe to do it all.

  • 94 / 100 | GEARIST | | Level 1 expert

    If you are stuck in a “shoe rut” and enjoy a responsive luggy durable trail shoe that offers a wide toe box and comfortable cushion, I would say give the Hierro V2 a try…you just might love it as much as I do.

  • 86 / 100 | Marqkria McMiller | Level 1 expert

    It is a soft shoe and offers a smooth, responsive ride. If it were not so narrow, I would consider it as my first option for long runs.
