NRG Air Carbon Reinforced

Totally renewed NRG Air improves in every aspect. Increased stiffness. Reduced weight. 5 different areations for optimal airflow. Compatible with SPD pedals. 


S.R.S. (Slim Ratchet System) is Northwave’s new micrometric buckle. Maximum closing precision, minimised size and weight. The mechanism follows the anatomic shape of the foot to ensure the most comfortable fit and is designed to ease the grasp even when riding. Forged in aluminum it’s great for top resistance and ease of replacement. 

Asymmetrical Straps

The asymmetrical construction is another innovation of the collection. The central strap is moved so as to follow the anatomy of the foot and reduce the pressure on the sensitive side. The straps have been lightened by all superfluous elements presenting thinner thicknesses and discharged central areas thereby maintaining maximum grip. 

Multilayer Thermowelded 

Northwave has extended to its entire new collection the use of thermowelded unibody uppers. Utilising thinner and lighter materials and almost complete stitching free. The upper is also crafted with larger air vents for improved comfort during pedalling.

Upper Construction 

Airflow system implementation means a better sole aeration.

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.

NW Biomechanical Mapping

From a biomechanical point of view the foot function is essential as it stores the force generated by muscles which is then transmitted to the pedal in the boost phase. 

The soles have been reduced in thickness but the overall stiffness has been increased so the mechanical energy transfer action from the shoe to the pedal can be concentrated in a small area. The upper has minimal stitching and is designed to anatomically follow the shape of the foot preventing slipping and providing an effective support. The vents have also been strategically placed along the upper and the sole to work as an integrated system designed to provide a constant air flow.
