The Sulfur S is a very sporty, technical approach shoe with a precise fit that combines climbing precision and grip in technically demanding terrain with consistently high wearing and walking comfort.
The robust, particularly light upper made of ballistic synthetic material is shaped around a special anatomical last and offers an optimal fit. The result is a shoe that hugs the foot like a sock. The midsole is made up of two zones of different densities that provide more cushioning and a smoother heel-to-toe transition when walking and greater torsional rigidity when climbing.
A TPU Edge Frame plate deployed just above the midsole provides extra support and flexibility right where it's needed.
The multi-directional outsole made of Vibram Megagrip takes on a wide variety of surfaces and weather conditions, while the profile-free climbing zone in the toe area and the Arch Grip made of rubber under the arch of the foot ensure high edge strength and climbing precision on rock.
This high-performance approach shoe fits like a glove and offers optimal support and lasting comfort even over long distances in rough mountain terrain.
