90 / 100 based on 3 expert reviews

    When I finally took them on the trail, I kicked up heaps of dirt due to the amount of room in the toe box. Brooks shoes are usually true to size, yet I’d recommend going at least a half size down, or maybe even a full size.

    At times, this shoe felt so refreshing on the trails. It was fun and fast. But the oddly long toe box and the complete lack of support in the heel/collar are frustrating for me. If you’re like Dave and don’t find that to be an issue, then you’ll love the PureGrit 8.

    PureGrit is the Revel of the Brooks Trail scene. Looks good, runs good, but gets overshadowed by the Cascadia. That said, I can assure you this shoe is fun.
