Northwave Celsius XC Arctic Gtx

The power is transferred to the drivetrain via the reinforced Jaws Carbon sole with a stiffness index of 8.0. The natural rubber heel area provides extreme grip on any surface. The upper shoe has an overlap construction made from the most innovative materials: it wraps the foot perfectly, avoids pressure points and transfers every watt of power to the drivetrain without loss. Additional TPU reinforcements offer 360° protection across the entire upper, while the SLW2 twist lock system ensures a simple and consistent fit. The only one of its kind, its micro-step ratchet system ensures millimetre-precise adjustment and adaptation of the shoe. The new Easyfit Climaflex entry area combines the extreme flexibility of the Gore-Tex Rattler membrane with the high thermal insulation of neoprene and guarantees mobility and protection against cold and wet conditions. The ergonomic heel shape with its anatomical fit thanks to the latest thermoforming technology in conjunction with the Arctic 4Layer insole made of EVA + aluminium and EVA + pile ensures excellent thermal insulation. The 360° reflective inserts ensure greater safety in poor visibility conditions.
