TrailRelease date 2026-03-19JP

Timp 6 GTX adds GORE-TEX Invisible Fit to the zero-drop Timp 6 trail platform. The sixth generation revises the upper, mesh, and Vibram Megagrip lug layout while retaining Altra EGO MAX foam. Its directly bonded waterproof membrane reduces the bulk of conventional waterproof construction, and the Soft Rolled Mesh uses 85% RPET. Standard FootShape fit supports long trail runs and hikes in wet conditions.
