    …a fantastic trail shoe, one that you need to consider.

  • 88 / 100 | Trail Hippies Hiking | Level 1 expert

    Highly recommended, [the] Merrell All Out Peak trail runner/hiking shoes. A lot less weight to deal with, a lot better experience, and also no blisters.

  • 96 / 100 | Active Gear Review | | Level 4 expert

    At a price of $130, this shoe is priced similar to most trail running shoes on the market and I feel with the quality of the shoe, it’s worth the price. Overall, a great trail running shoe.

  • 83 / 100 | Trail to Peak | | Level 4 expert

    I prefer a little more burliness and stability in footwear, and I really like the added protection in the Peak.

  • 92 / 100 | Seven Hills | Level 1 expert

    The Peak easily handles: mud, icy snow, wet wooden bridges, and slick pavement, while providing tremendous rock protection.

  • 84 / 100 | rocky555 | Level 1 expert

    On the same places where I would slide with Salomon, these hold the grip (I have tested this for fun on 2 consecutive days on the same trail route, first with Salomon and then with Merrell).
