5 reasons to buy

  • The upper unit of the Mudclaw 300 is flexible and durable, allowing for a reliable coverage to the foot, remarked some runners.
  • Most reviewers appreciated the mesh lining and the water repellent coating that keeps the foot clean and dry.
  • A large number of runners welcomed the protective components, such as the Gusseted Tongue, which keeps dirt from entering the shoe.
  • EVA makes up the mid-sole layer and it’s coupled with the Meta-Shank groove design on the forefoot for more natural foot movement.
  • The Dual-C outsole is made up of sticky rubber for more durability and grip on the surfaces.

3 reasons not to buy

  • Some runners felt that the Mudclaw 300 wasn’t true to its size because it was one size smaller than the usual.
  • Others thought that it was greatly missing the arch support needed for many runners who need such a feature.
  • The testers noticed that the outsole wasn’t able to offer much traction on wet surfaces.

Bottom line

The Mudclaw 300 from Inov-8 is a trail shoe that’s made for hard terrain and hardened trail enthusiasts who want to experience a solid option when adventuring. It’s sturdy, durable and comfortable to wear for neutral runners.

85 / 100 based on 9 expert reviews

  • 87 / 100 | OCR Life

    You know, minimal shoe, drains well, looks great, fantastic grip.

  • 85 / 100 | Terrain Tactics

    As far as an overall OCR shoe, I highly recommend the Inov-8 Mudclaw 300.

  • 88 / 100 | Runblogger

    The upper is near mountain shoe perfection, and the outsole is sticky, aggressive, yet still runs ok on harder terrain (and much better than inov-8’s x-talon and Terraclaw outsoles). 

  • 85 / 100 | Ian Corless

    A fully gusseted tongue helps keep any debris out.
