Crafted to lead the pack at the world’s pinnacle trail races, the Tecton X 4 is freshly finessed with PROFLY™ X series technologies for speed on gnarly terrain. Parallel carbon plates are adjusted to increase pop in the gait cycle and a new Matryx® Micro textile upper enhances breathability during all-out efforts. Built with two layers of PEBA—our lightest, most resilient foam—and finished with an extended knit collar and updated lace structure for better lockdown and support, this beast has course records in its sights.
