    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.

  • 95 / 100 | A Run Through The Woods | | Level 1 expert

    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.
