Merrell Agility Peak 4: Run all terrain with protection 

There are three elements of the Agility Peak 4 that make it such a versatile and protective shoe: (1) copious amount of cushion, (2) rock plate, and (3) grippy Vibram Megagrip outsole. Combined altogether, they help mute out impact shock and keep the foot well-shielded from harsh ground elements. 

And to make the Agility Peak a true multi-terrain trail shoe, it's made with a very clingy outsole. Throw just about anything at it, and it can handle it with ease. 

Who and what is it for? 

Since the Agility Peak 4 has a lot of cushion, it's suited for beginner to intermediate trail runners, heavy runners, and can even accommodate ultrarunners. It may tackle a lot of surfaces, but it also has its limitations. To find out, read on.

Merrell Agility Peak 4 vs. 3

Lighter, more protective ride: This is owed to the more featherweight but more abundant FloatPro foam of the shoe. It cradles the foot and absorbs impact effectively without adding any bulk.

Better grip: With an updated Vibram Megagrip outsole, the shoe has better traction than its precursor, and can handle more terrain. 

More protection: Designed with a rock plate, the shoe keeps the foot safe from any abrasive and sharp ground elements. 

Enhanced lockdown: With a new tongue design (gusseted/attached to the sides), the heel and midfoot are made more secure.
