Northwave Celsius XC Arctic GTX winter shoe

Power transmission is given from the Jaws Carbon Reinforced sole with a 8.0 stiffness index and a natural rubber tread heel for extreme grip on any surface.
The upper has the overlap construction, which wraps the foot without any pressure point, helping to transfer every watt of power, eliminating the dispersion of energy. Furthermore, the TPU reinforcements ensure a 360 ° strategic protection along the entire upper.
An easy and even closure system is guaranteed by the SLW2 dial, the only one with a step-by-step release, which allows a millimetric adjustment of the shoe in a fast and intuitive way. The new Easyfit Climaflex collar combines the extreme flexibility of the Rattler® Gore-Tex membrane with the high thermal insulation of Neoprene, for more mobility and protection.
The wrapping and positioning of the heel are enabled by an anatomic seat and a solid thermoformed counter, in addition to the Arctic 4Layer insole made with Eva + Aluminum + Eva + Pile, which guarantees excellent thermal insulation. For safety, the 360° reflective inserts provide added visibility on the road.
