Northwave Biomechanical Mapping (BioMap) Your energy is precious, never waste it. That’s why Northwave shoes are designed with BioMap technology. Northwave soles, uppers and all their components are anatomically compatible with every cyclist’s feet and are designed to keep the foot in the right position while pedaling, transmitting power directly to the pedals without wasting any energy. Ultralight Carbon Sole With maximum stiffness, minimal thickness and truly unrivaled lightness, this is the sole of choice for the best athletes. The evolution of the Airflow System offers added ventilation. it weighs just 60g. Northwave Speedplay Adaptor Kit 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 the 3mm of the traditional Speedplay adaptors. Made of nylon with a thin aluminum plate (it saves 8,5gr) it allows to respect the natural anatomy of the sole keeping minimized the distance between the foot and the pedal in any position. Without adding bulk and weight as it occurs in systems without the adaptor. AirFlow System It’s the Northwave ventilation system with large vents that lets your feet breathe: the lower vent channels air inside the sole, while the side vents guarantee a supply of fresh air. SLW2 Closure System The micrometric system S.L.W. 2 (Speed Lace Winch) represents the evolution of the closure system. 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. More lightweight and thinner. The dial has been completely redesigned in size and weight, resulting in being significantly lighter and thinner. The external covering in soft touch material also makes the grip more effective. The ergonomic shape of the S.L.W. 2 ratchet follows the anatomy of the foot to make it really comfortable. The S.L.W. 2 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 to integrate an efficient heel retention system inside the structure, without the need of external elements. Same efficiency, reduced weight. No-Slip Heel The interior of the upper in the heel area has been lined with a specific gripping material whose fibers oriented in a single way facilitate the entrance but at the same time prevent the heel from slipping, providing a perfect foot hold. Extreme Air Footbed Ultralight, anallergic and antibacterial, it keeps your feet amazingly fresh with numerous vents that correspond with the vents on the sole.
