The upper of the Agility Peak 4 GTX has a degree of stiffness and there are additions all over that signal its intentions as a rugged trail shoe. A Gore-Tex lining is one thing, but there is also a D-ring at the base of the laces for gaiters and a stiffened toe cap that extends right around the toe box. TAYLOR : I feel it appropriate to pop the bubbly in honor of Merrell. We’ve received four models of trail shoes from the brand recently and they’re batting 1.000. The Agility Peak 4 is well prepared for going long distances over rough terrain. You’ll find it to be a little heavier (11.6 ounces for a Men’s 10.5), moderately stable, and more fortified than their recent MTL Long Sky .

The heel might be lower than some, but Merrell has made that work for the shoe with a superb roll. It also combines well with the responsive midsole to give a sturdy build that can be taken anywhere, even on steeper slopes, without discomfort.MATT : There were a few things I didn’t love about the shoe. The FloatPro midsole provides a stable and secure ride but sometimes feels too stiff. While I didn’t expect a lot of bounce, on some stretches the shoe just felt flat. This would concern me more knowing that it’s built for long distances, and I could feel my legs taking a pounding towards the tail end of my longer efforts.

Underneath needs a whole lot less explanation: Vibram MegaGrip + Deep multidirectional chevron lugs = Optimal grip for any surface. MATT : There is a lot to like about the Merrell Agility Peak 4. While the shoe has its flaws, I think it’s a case of using a tool for what it was designed to do. For the Agility Peak 4, that’s shredding gnarly terrain and making you feel like the king/queen of the mountains. The midsole has been beefed up in this fourth version but tries to keep extra weight at bay by using a lightweight foam Merrell calls FloatPro. For the outsole, Merrell has used Vibram MegaGrip with aggressive 5mm lugs. The Hoka One One Challenger ATR 5 GTX (retailer link) is a waterproof, comfortable and durable trail running shoe, the ideal choice for runners who appreciate functionality over looks. Not saying the Challenger ATR 5 GTX is an ugly shoe, but its main appeal is not aesthetics for sure, it will more likely win you over with just how great it feels to run in it. Guaranteed.MATT : Out of the box the Agility Peak 4 is a head-turner. With its bold contrasting colors and aggressive look, I fielded a number of comments about the shoe from interested runners before even logging a mile. As for shape, it feels most similar to a Salomon Sense Ride . Personally, that’s a great thing. They offer a snug fit with a more generous toe box than most other technical trail shoes on the market. Overall, the Agility Peak 4 GTX is an impressive trail running shoe. Though not for speed, and somewhat mired by sub-par (or at least unclear) brand sustainability, it’s a versatile option.
