    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).

    The wide toe box and the rounded toe will accommodate any runner and can help any feet on the inside, regardless you are a barefoot runner, minimalist or a real fell runner.

    These are not an all-purpose pair of trail shoes but in the environment that they are intended for, i.e. ankle deep British mud, they inspire huge amounts of confidence.

    However I felt that the previous rounded heel was a bit better for steep contouring – I suppose you can’t have both.

    Standard Mudclaw outsole, which are very aggressive. Great for your soft, muddy conditions. It allows the mud and dirt to fall off quite easily, giving you grip on all terrains.
  • Brett Shop Zappos
    This terrific trail runner has an upper crafted from durable textile and synthetic materials, with plenty of detailed stitching throughout.
