Power transmission is given thanks to the NRG Air Carbon Reinforced sole with a rigidity index of 8.0 while the upper has the overlap construction, which reduces the aerodynamic resistance evenly binding the foot without any pressure point and helping to transfer every watt of power cancelling the dispersion of energy.The toe is reinforced in anti-abrasion and 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 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, providing mobility and protection.The wrapping and the positioning of the heel are guaranteed by an anatomic seat and a solid thermoformed buttress and the Arctic 4Layer insole built in Eva + Aluminum + Eva + Pile ensures excellent thermal insulation.For added safety, the 360 ° reflective inserts enable major visibility on the road.
