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.
Ultralight PU
S.R.S. (Slim Ratchet System) is Northwave’s new micrometric buckle. Maximum closing precision, minimized 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 to the center so as to follow the anatomy of the foot and reduce the pressure on the side area, because particularly sensitive. The straps have been lightened by all superfluous elements, presenting thinner thicknesses and discharged central areas, thereby maintaining maximum grip. 
Performance Advanced
Ergonomic design: because you need to keep the perfect position when pedaling and you want comfort too.
  • SPD pedal compatible
  • 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. 
Each element of the BioMap shoes by Northwave has been designed to keep the foot in the correct position while pedalling, transmitting the force directly on the pedals without loss of energy. 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 had its stitching minimized 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.
Multilayer Thermowelded 
Northwave has extended to its entire new collection the use of thermowelded unibody uppers. Two main advantages are:
  • Use of thinner and therefore lighter materials
  • Almost complete stitching elimination

The upper results are a more anatomical fitting, in order to better envelop the foot. Thanks to this technology, the upper features larger air vents resulting in improved comfort during pedalling.
