Building on the success of one of Merrell's most popular trail running shoes, the Agility Peak 5 updates this already successful trail runner. In this latest version, the rocker is increased, weight is reduced to less than 10.5 ounces, and heel cup sculpted for better on foot comfort and less slip - whether you are running an ultra or training for your next trail 5K, the Agility Peak 5 will be your next go to trail shoe for any condition comfort.
