Ready to propel you through gnarly terrain, the Tecton X 3 adds winglets to its carbon fiber plates for extra stability in just the right spots, and two layers of PEBA in the midsoleour lightest, most resilient compound. Redesigned lug shape and positioning on a Vibram Megagrip with Litebase outsole provide better traction, while a dynamic vamp allows feet to splay as the miles fly by. Topping it off, a knit collar extends up from the tongue like a gaiter to mitigate trail debris, and a lightweight Matryx textile upper makes this version more durable and trail-worthy than ever.
