Lone Peak 9+
Lone Peak 9+ is a zero-drop trail shoe for running, hiking, and thru-hiking. A Vibram Megagrip outsole with revised lugs improves traction on wet and dry terrain. Altra EGO cushioning and a 25 mm stack preserve ground feel, while Original FootShape fit leaves room for toe movement. An RPET ripstop-mesh upper, no-sew overlays, dual toe guard, and a thin full-length TPU StoneGuard add durability and protection.
