These Extreme Road Shoes from Northwave have Ultralight Carbon 14 soles made of 100% unidirectional carbon with a stiffness index of 14.0 for top power transfer. They are NW Speedplay adapter compatible providing the lowest stack height between feet and pedals.
These shoes feature micro-perforated BioMap unibody uppers that are made of ultralight microfibre which morph to the shape of your feet and have a highly reflective coating on the uppers that provide unparalleled 360° visibility, even in poor light.
The integrated heel system contains directional fibre to prevent any slipping while the double SLW2 dial provides step-by-step and full release in a single button plus an extra strap for exceptional pressure distribution.
BioMap: Your energy is precious, never waste it. That’s why Northwave's shoes are designed with BioMap technology. Northwave's soles, uppers and all their components are anatomically compatible with every cyclist’s feet and are designed to keep your feet in the right position while pedalling, transmitting power directly to the pedals without wasting any energy.
Ultralight Sole: The 100% unidirectional carbon sole ensures exceptional power transmission with the minimum thickness and an incomparable lightness. The adapter is compatible with Speedplay pedals while the Airflow System fosters a greater circulation of air in and out.
Speedplay Adaptor: The shortest distance between foot and pedal on the market. Northwave developed and patented, in collaboration with Speedplay, an exclusive adaptor that provides maximum power transmission on pedals, thanks to the reduced thickness of just 0.5mm rather than the 3mm of traditional Speedplay adaptors. Made of nylon with a thin aluminium plate (saving 8.5g), it allows respect of the natural anatomy of the sole, keeping the distance minimised between the foot and the pedal in any position without adding bulk and weight.
Airflow System: Northwave's ventilation system with large vents that let your feet breathe: the lower vent channels air inside the sole, while the side vents guarantee a supply of fresh air.
SLW2 Closing System: The micrometric system SLW2 (Speed Lace Winch) represents the evolution of the closure system and provides maximum precision and modularity. The innovative step by step closure means you can tighten and enlarge the fit in a few moments.
The side button provides a dual function: by pressing, it features a micrometric release and lifting it allows a complete and immediate opening of the shoe. The dial has been completely redesigned in size and weight, resulting in being significantly lighter and thinner. The external covering of soft touch material also makes the grip more effective.
The ergonomic shape of the SLW2 ratchet follows the anatomy of the foot to make it comfortable. The SLW2 ratchet is easily replaceable. The cables come from the best technology derived from the world of sailing.
Integrated Heel System: The new unibody construction of the uppers allowed integrating an efficient heel retention system inside the structure, without the need of external elements; this gives you the same efficiency but reduced weight.
