Northwave Sonic Srs Shoes Size 42

NRG Air provides increased stiffness thanks to the new blend of nylon reinforced with fiberglass and enriched with carbon. As with the whole road soles collection, it features the AirFlow ventilation system. Vents favour an optimal airflow in and out.

S.R.S. (Slim Ratchet System) is Northwave’s new micrometric buckle. It offers maximum closing precision while minimizing size and weight. The mechanism follows the anatomical shape of the foot, ensuring a comfortable fit, and is designed to be easy to grasp even when riding. Forged in aluminum, it offers excellent durability and ease of replacement.

The Airflow System, a key feature in Northwave products, provides excellent ventilation. Large vents allow your feet to breathe, with lower vent channels directing air into the sole, while side vents ensure a continuous supply of fresh air.

The asymmetrical strap construction is another innovation in this collection. The central strap is repositioned to the center, following the foot's anatomy and reducing pressure on the sensitive side area. Straps have been streamlined, featuring thinner profiles and relieved central areas while maintaining maximum grip.

The Multilayer Thermowelded construction is achieved by coupling a light microfiber with large thermowelded mesh vent inserts, resulting in improved comfort and reduced weight.

The Integrated Heel System benefits from the new unibody construction of the uppers, integrating an efficient heel retention system within the structure, eliminating the need for external elements. This design maintains efficiency while reducing weight.
