Lone Peak 9+ GTX

TrailPlanned release 2026-02-06JP

Lone Peak 9+ GTX keeps the Lone Peak 9+ platform and adds a GORE-TEX Invisible Fit upper for waterproof, breathable trail use. Rolled mesh reduces waterproof-shoe stiffness. Altra EGO cushioning, a 25 mm zero-drop platform, and Original FootShape fit preserve its trail feel. Vibram Megagrip supplies traction on wet rock and mud, while GaiterTrap helps keep debris out during runs and hikes in changing weather.
