The Agility Peak 6 is Merrell's do-it-all trail running shoe, the one you reach for when the route mixes mud, rock and long slow miles. It sits in the cushioned-but-planted camp: a generous FloatPro midsole under an aggressive 5mm Vibram Megagrip outsole, with an 8mm drop and a 38mm heel stack that soaks up rough ground without floating you off it. This is not a racer and it does not pretend to be. It is a dependable daily trail trainer built for grip, protection and staying comfortable when the run drags on. We rate it as one of the best value all-rounders in its class, and RunRepeat's 84/100 backs that up. If your trails are technical, wet or steep and you want one shoe that copes with all of it, the Agility Peak 6 is an easy shoe to recommend. Compared with the pricier Hoka Speedgoat 7, it trades a little plushness for a firmer, more connected feel underfoot.
The Agility Peak 6 comes up true to size for most runners, so order your usual trail number. The fit is secure rather than roomy: a medium-to-slightly-snug midfoot that locks the foot down well for off-camber and technical ground, which is exactly what you want when you are picking a line through rocks. The toe box gives enough room to splay on descents without feeling sloppy, though runners with genuinely wide feet or those who like a lot of forefoot space may find it a touch close and might prefer the roomier Altra Lone Peak 9. Heel hold is one of the shoe's quiet strengths, with a well-shaped collar that stops lift on steep climbs. If you run in thick winter socks or your feet swell on long ultras, consider going up a half size. Otherwise stick to true to size and lace to a comfortable lockdown.
On the trail the Agility Peak 6 rides planted and confident rather than bouncy. The FloatPro midsole is on the firmer side of cushioned, which keeps you connected to the ground and stable when the terrain turns awkward, but still takes the sting out of rocky sections and hard-packed paths. It is not a shoe that pushes you to run fast. It is a shoe that lets you settle into a rhythm and hold it for hours. Turnover feels natural thanks to the moderate 8mm drop, and the shoe stays composed on descents where softer, taller trail shoes can feel vague. Pace it as a daily trainer and long-run companion and it rewards you with all-day comfort.
With a 38mm heel and 30mm forefoot stack, the Agility Peak 6 has enough foam to protect your legs over long distances while staying grounded and controllable. The FloatPro midsole leans firm and supportive, so you get impact protection without the disconnected, wobbly feeling that very soft trail shoes can have on uneven ground. That firmness is a plus on technical terrain and a fair trade if you value stability over a plush, sink-in ride. Over a long day out the cushioning holds up well and your legs stay fresher than the modest price suggests. Runners chasing maximum softness for smoother trails may want something plusher.
This is not a motion-control shoe, but it is one of the more naturally stable trail options at the price. The firmer FloatPro foam, the secure midfoot wrap and a broad, grippy outsole platform all work together to keep you planted when the ground tilts and shifts. On off-camber traverses and loose descents the Agility Peak 6 feels sure-footed and predictable, which builds real confidence when you are running tired. Neutral runners will feel well supported. Those who need dedicated stability posts or a medial device for overpronation should still look at a purpose-built support shoe, since there is no corrective structure here.

The upper is built for the demands of the trail: protective, breathable enough for UK conditions, and reinforced where you need it around the toe and midfoot. It wraps the foot securely without hot spots, and the gusseted-feeling tongue and shaped heel keep grit out and lockdown consistent. Break-in is minimal, so most runners can head straight out for a long run. Drainage and breathability are respectable, though like most cushioned trail shoes it is not the fastest to dry after a deep bog crossing. For day-to-day mixed-terrain running through the seasons it strikes a sensible balance between protection and comfort.
