Ultralight Carbon 15 sole
High level power transmission! Northwave has added a reinforced layer to the Ultralight Carbon 15 sole to make it even stiffer and create the best-performing Northwave sole ever. They've kept all the features that made it the favourite of their Pro riders: minimum thickness and unmatched lightness. A special adaptor makes it compatible with Speedplay pedals, while the AirFlow system with seven vents improves the flow of air in and out of the shoe.
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.
X-Frame® by Northwave is an innovative design, engineered to transfer every watt of power while providing the snuggest, even fit with no pressure points. Totally unique, it combines next-generation materials that are only 0.5 mm thick and ultra soft for exceptional comfort with a structure featuring 360° reinforcements along the length of the foot that connects the sole to the laces via the upper. The result: a snug fit and perfectly balanced closure that pulls evenly around the entire foot from toe to instep. Kudos goes to the innovative route taken by the cable through special tapes: it passes through a complex system of angles and geometric precision made possible purely by relentless testing on countless prototypes. The SLW2 dial closure system works with the X-Frame design, replacing plastic inserts with soft tapes, while the soft, flexible Dyneema cable naturally conforms to the shape of each foot.
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.
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.
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.
