Northwave Celsius R Arctic GTX

A very good power transfer is guaranteed thanks to the fiber-reinforced NRG Air Carbon sole with a stiffness index of 8.0. The upper shoe, with its overlap construction, reduces wind resistance by evenly securing the foot without pressure points, helping to transfer every watt of power precisely. The reinforced and abrasion-resistant toe area, combined with the SLW2 dial closure system, allows for millimeter-precise adjustment of the shoe with its micro-step ratchet. The new Easyfit Climaflex collar in the entry area combines the extreme elasticity of the Gore-Tex Rattler membrane with the high thermal insulation of neoprene, thus increasing mobility and protection. The ergonomic heel shape, with its anatomical fit thanks to state-of-the-art thermoforming technology, along with our Arctic 4Layer insole made of EVA and aluminum, as well as EVA and pile, ensures excellent thermal insulation. For added safety in poor visibility conditions, the 360° reflective inserts provide extra visibility.
