The Sulfur GTX is a fast approach shoe with a snug fit that offers precision while climbing and grip on technical terrain. It is extremely comfortable and effortlessly accompanies you through long hiking days. The durable upper made of 1.5 mm thick suede features a breathable and waterproof GORE-TEX lining that keeps your feet pleasantly dry in all conditions. The shoe is shaped on a special anatomical last to ensure a precise fit. The result: it fits like a glove! The midsole has two areas with different densities, combining excellent cushioning and a smooth roll-off of the foot while walking with good torsional stiffness while climbing. All of this is enhanced by the Edge Frame technology: a TPU plate inserted in the middle of the shoe provides support and flexibility where you need it. The composite sole Vibram Megagrip features a multidirectional tread pattern that easily adapts to different terrains and changing conditions. The flat area under the toes and the rubber grip under the arch provide additional power on the sides and precise hold on rock slabs, ledges, and edges. Our high-performance approach shoe offers you a snug fit, good grip, and lasting comfort, allowing you to cover longer distances in rugged mountain terrain.
