4001 GTX | Ultra-technical boot for high altitude mountaineering

After dedicated anatomical and dynamic studies on the different phases of foot movement during every kind of alpine activity, the Kayland 4001 GTX was born; an ultra-technical boot, that thanks to its ergonomic and highly performing construction allows excellent feats to any type of alpinist, for the real mountain professionals and for the mountaineering and alpine travel enthusiasts. In fact, with all this package of features and excellence, this Kayland premium style is perfect for mountaineering up to 4000 meters, for glacier excursions and for ice climbing, with a complete capability with automatic crampons.
 
The upper holds the extreme effort to reach a stylistic, technical and anatomical perfection: the synthetic fabric of the gaiter, anti-abrasion and nati-cut, is closed with a waterproof asymmetrical zip, that following the lines of foot and heel gives to the boot a high degree of ergonomics and protects from water. The upper part of the heel is made with elastic material to wrap around the calf properly. The Gore-Tex® Insulated Comfort Footwear membrane guarantees waterproofness and breathability to the foot, enhancing the internal comfort of this footwear. The rubber rand, revolving all around the boot, is built with Diamond Technology, an exclusive polyurethane material that offers an utmost resistance to abrasion never seen before.
 
The lower part of the boot is the heart of high standard performances. The complexity of the insole, made with fiber glass and aluminium foil for great thermal insulation, is necessary to keep the right torsional rigidity for a safe use of crampons. The Smart PU wedge, with two density of polyurethane, delivers great cushioning of impacts with ground and stability on all surface, even the most rambling. The TPU inserts on heel and toe box are the standard for a safe and precise automatic crampons hold. The Vibram® Mulaz Evo sole has a specific design for mountaineering and ice climbing: the solid areas on tip and heel provide better grip and increase safety, whilst the sticky compound, engineered exactly for European mountaineering, stands with an elevated grip in every condition and on every surface.
 
For any passionate climber who want to challenge the most demanding mountains, in any weather, the 4001 GTX is the choice.
