Description of Northwave Sonic 2 Plus Road Shoe - 03 black/white/red
High tech is no longer just for pros. Shoes with top-spec solutions, such as a thermowelded multilayer construction with no overlaps, SLW2 dial closure and NRG Air Carbon Reinforced sole with five vents for optimum airflow.
NRG Air Carbon Reinforced Sole: NRG Air Carbon Reinforced 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 air flow in and out. Compatible with SPD pedals.
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.
S.L.W. 2: Maximum precision and usability. The side button
offers dual functionality: press the button for micrometric release, or lift the button to instantly undo the shoe completely.
The ergonomic shape of the ratchet base matches the shape of the foot for added comfort, while the size and minimized weight plus the outer soft-touch covering make it easier and better to grip. It features wires that harness the best technologies used in sailing, and can be easily replaced using the spare parts kit.

Regular Fit: Tests on hundreds of feet and countless trials have created the perfect shape for transferring 100% of your power straight to the pedals. The toe is designed to be just the right size to prevent any numbness, while the slightly set-back instep and the special snug-fitting design of the heel hold the foot in place during every pedal stroke and prevent
