What are the Viaz DFS?
Whether taking on a Via Ferrata challenge or heading on a technical mountaineering adventure, the Viaz DFS provide ample waterproof protection and durability for demanding terrain. They're built with reliable Gore-Tex® technology and feature an exclusive fit system for optimum precision and performance.
What are they made of?
Upper: The uppers are made from Air 8000, making the Viaz DFS an impressive 11.5 times more breathable than traditionally constructed fabric boots! This is achieved by laminating the lining fabric to the face fabric using microdot net glue, which uses adhesive in a matrix pattern to ensure maximum breathability and structural integrity. Other manufacturers use a complete layer of glue to stick the lining to the outer; this effectively blocks up the fabric and significantly reduces breathability. Welded PU film and a rubber rand provide further protection for increased longevity and durability.
Lining: A Gore-Tex® Performance Comfort lining provides ample waterproof protection whilst remaining breathable, helping to prevent sweat and moisture build-up inside the boot. It uses a four-layer laminate construction, including a protective knit layer that feels smooth to the touch.
Footbed: A Custom Fit footbed provides ample cushioning and immediate under-foot support with light warmth.
Midsole: Double-density PU foam enhances comfort and helps to absorb shock and impact when moving on hard ground.
Outsole: The Vibram® Croda Litebase outsole provides stability, grip and precision for technical terrain and situations. It uses a special slim construction to help keep the boot's weight to a minimum without compromising performance and functionality, helping you to feel confident with each step.
What are their features?
The Vibram Litebase sole allows for using both traditional and semi-automatic crampons for icy weather.
Dynamic Fit Technology adapts the boot's heel tension with your natural stride, increasing comfort and stability for moving on uneven terrain.
The exclusive AKU Dual Fit System (DFS) provides a customised and precise fit. It combines a comfort-walking lacing system with a climbing lacing system to wrap the boot around the foot more closely and maximise support for climbing and scrambling. These laces are integrated into the body of the shoe and increase functionality for multi-activity use. This system also lets you adjust the fit quickly without retying your laces.
These boots also have a built-in Elica Natural Stride System integrated into their last, insole board, midsole and outsole. It ensures an anatomical fit to provide enhanced stability and weight distribution, helping to reduce uncomfortable pressure points and encourage better form as you walk. This anatomical fit will also help to reduce foot fatigue and impact for longer distances, keeping those aches at bay.
