    All in all the boots held up well and kept my foot dry.

    This shoe is heavier than most trail running shoes-it has a lot of girth-but feels less so in sloppy, wet terrain or snow.

  • 94 / 100 | Outside

    Lightweight and bomber, these are the shoe-boots you want when the singletrack gets muddy.
