    The Inov-8 255 is my favorite long distance offering from the company and I will continue to keep this shoe in the regular rotation for some time.

  • 65 / 100 | Minimalist Running Shoes | | Level 4 expert

    It may have too much protection for non-technical trails or flat trails but for cross country training, it is fine. For racing, I would definitely prefer a lighter and lower to the ground model

  • 84 / 100 | Running Warehouse | | Level 2 expert

    Even though I have a narrow foot, I found the anatomical fit to allow me to run a little more naturally and get a better feel for the trail.

  • 78 / 100 | Rise to It | Level 2 expert

    The sole is ideal on loose and eroded trails where it will bite down while still dispersing impact efficiently on the harder trail surfaces.

    My overall impression is that I'm definitely a fan of the shoes and I think they're a great fit for some of the tougher mountain terrain.
