The versatile Terroc is ready for winter. The Terroc 345 GTX is Gore-Tex lined to provide a breathable, waterproof barrier between your foot and the elements. The low-profile platform is stable and the tread works well over a variety of terrain. A touch of road, here and there, is OK, but this shoe is for serious trail running. Dirt, rocks, streams, gravel, grass. Bring it on.
