Northwave Celsius R GTX Shoes. Power transmission is given thanks to the NRG Air Carbon reinforced sole with a stiffness index of 8.0 while the upper has an overlapping structure, which reduces aerodynamic drag by evenly binding the foot without any pressure point and helping to transfer every watt of power by eliminating the dispersion of energy.
The toe is reinforced in abrasion resistant and an easy and uniform closure system is guaranteed by the SLW2 closure, the only one with a gradual release, which allows a millimeter adjustment of the shoe in a quick and intuitive way. The new Easyfit Climaflex collar combines the extreme flexibility of the Gore-Tex Rattler® membrane with the high thermal insulation of neoprene, offering mobility and protection. The wrapping and the positioning of the heel are guaranteed by an anatomical shape and a solid thermoformed buttress and the Arctic 4Layer insole built in Eva Aluminum Eva Pile guarantees excellent thermal insulation. For added safety, 360 ° reflective inserts allow for greater visibility on the road.
