Kern S1 Brown / Lime
These outsoles are made of real rubber for maximum grip. Distinct 3mm deep Y-pattern lugs are designed for reliable multi-directional hold on most surfaces.
Known as the tough rope relied on by mountain climbers as the lifeline that safely bears their weight and that of their equipment and supplies. KERN uses a rope strap with the same durable nylon core (120kg rating,) but with a softer nylon shell for comfort.
Steel-Reinforced Contoured Sole
In between the shock-absorbing, ultralight phylon topsole and the resilient rubber outsole, a 1mm thick metal spine is embedded. This is designed to provide unparalleled rigidity that allows the sole to keep its contoured profile. These components are then machine-pressed to maintain a consistent ergonomically-correct shape.
