82 / 100 based on 5 expert reviews

  • 96 / 100 | iRunFar

    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

    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

    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

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