THE SULFUR IS A FAST-MOVING APPROACH SHOE WITH AN ANATOMICAL, WRAPPING FIT AND GOOD SUPPORT AND ENDURANCE COMFORT.
IT DELIVERS GRIP, PRECISION AND CLIMBING PERFORMANCE IN TECHNICAL TERRAIN.
Technical approaches in variable mountain terrain require comfortable support and stability and a superior level of grip and precision. The Sulfur upper is built and shaped around a specific anatomical last that delivers a precise, wrapping fit.
As a result, the shoe fits like a glove around the foot.
Its excellent forefoot and heel retention provides solid support for high performance in even the most technical terrain.
ADAPTIVE SHAPE TECHNOLOGY
BUILT AROUND YOUR FOOT
Each foot is unique, this is a fact.
Tecnica AST (Adaptive Shape Technology) combines a range of advanced technical solutions. By combining different density adaptive EVA memory foams with pre-shaped thermoplastic inserts and an Ortholite footbed, we deliver a unique, anatomic underfoot construction that adapts to the shape of your foot.
TOE LACING SYSTEM
FOR ADJUSTABLE FIT, PRECISION AND PERFORMANCE
The climbing lacing system supports the wrapping fit at the forefoot and toe box and allows for extremely quick and precise lace adjustment.
In addition, it enhances the advanced level of precision and edging when climbing steeper rock.
Supportive Midsole Structure
Edge frame technology
SUPPORT AND FLEX – EXACTLY WHERE YOU NEED IT
The edge frame plate is placed at the core of the shoe, stiffness and support while climbing, while still allowing the shoe to flex freely where needed.
The result: climbing performance meets hiking comfort. The longitudinal elements promote stiffness and torsional rigidity at the toe and midfoot. The cut-out crossways arrangements allow for more flexion in the metatarsal area.
Dual density
support
BI-DENSITY COMPRESSION MOLDED EVA WITH HIGH REBOUND COMPOUND
The Sulfur midsole is specifically designed with two different density areas: a higher density area from the midfoot to the toe and a lower density area underneath the heel.
The higher density EVA ensures torsional rigidity and flex stability – adding further support to the edge frame technology.
BALANCED CUSHION
The midsole is specifically designed with two different densities.
At the heel, it uses a softer EVA compound – to provide greater cushioning and ground adaptability. This guarantees optimal comfort when walking.
FAST TRANSITION
The midsole and outsole rocker profile is built with a precisely-defined shape to promote smoother heel-to- toe transition. As a result, the user can go for longer distances with a higher level of comfort.
TECHNICAL FEATURES
grip
VIBRAM® LITEBASE MEGAGRIP™ SOLE
The Vibram® Megagrip™ outsole offers unparalleled grip on both dry and wet surfaces. This compound is best-in-class for durability and ground adaptation. The multi-directional lug pattern is ready to take on different terrains and changing conditions.
CLIMBING ZONE
EDGING PRECISION
At the toe, the Sulfur outsole has a flat climbing zone. This dedicated climbing-specific feature gives advanced precision, toe and edging power on slabs, ledges and edges, making it the perfect choice for steeper walls.
ARCH GRIP
ENHANCED TRACTION
At the center of the Vibram® outsole, under the arch of the foot is the rubber arch grip. It delivers additional technical performance to the shoe.
The specific shape of its ‘teeth’ ensures better grip on slippery ridges and raised edges, as well as via ferrata rungs and ladders.
LIGHTWEIGHT RUBBER RAND
EXTENDED FRONT AND SIDE PROTECTION
At the toes and lateral and medial side of the foot, a lightweight rubber rand provides additional protection and abrasion resistance from boulders, rocks and scree.
BACKLOOP
EASY PULL-ON AND HARNESS ATTACHMENT
The Sulfur features a robust backloop that helps to pull on your shoes. It also enables quick and secure attachment at the back of your harness.
WATERPROOFNESS AND BREATHABILITY
GORE-TEX®
We use proven upper materials to deliver durably waterproof and breathable weather protection. The Gore-Tex® Extended Comfort membrane ensures that your feet stay dry and comfortable all day long and all year round.
