The Tecton X 3 is ready for the most challenging terrain, with lugs added to its carbon fiber plates for stability in all the right places, and two layers of PEBA, our lightest and most resilient compound, in the midsole. A redesigned lug shape and placement on the Vibram® Megagrip outsole with Litebase provide better traction, while a dynamic vamp allows for the natural swell of your foot as you rack up the miles. Completing the look is a textile collar that rises from the tongue like a gaiter to limit trail debris, and a lightweight Matryx® textile upper that makes this model even more durable and trail-ready.
