Building on the success of one of Merrell's most popular trail running shoes, the Agility Peak 5 provides updates to this already successful trail runner. In this latest version, the rocker is increased, weight is reduced to less than 10.6 ounces, and the heel cup is sculpted for better on foot comfort and less slip. Whether you are running an ultra, competing in cross country, or training for your next trail 5K, the Agility Peak 5 GTX is your go-to trail shoe for any condition with maximum cushion and comfort, with GORE-TEX® waterproof protection for ultimate waterproof functionality.
