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.
