A dynamic shift in trail running. Reengineered to maximize weight savings, the Tecton X 2 has been refined with a brand new Matryx ® upper. Light, breathable, and inherently hydrophobic, our high-contrast Matryx ® upper enlists a lay-flat gusseted tongue to help mitigate trail debris. A propulsive trail runner designed to inspire confidence on varied terrain, the Tecton X 2 is propelled by the same parallel carbon fiber plates that made its predecessor a fast favorite among trail running enthusiasts.
