    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.

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

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

    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).

    But their quirks may put off some people, especially the weird lacing system.

    With its protection, grip, and comfort, it’s a pretty perfect shoe for just getting into ultra-trails, if your heels can handle it.
