Cycling shoes Northwave Sonic Plus Road (white / black)

Northwave Sonic Plus Road road shoes feature a Morph sole with the Powershape system, which supports the arch of the foot and adapts to the foot. Two air channels in the sole and ventilation openings integrated into the upper provide airflow. The asymmetric upper, made from composite materials, offers fit and support.

The X-Dial SLW3 closure system allows precise adjustment. Three cleat mounting holes provide a 5 mm adjustment range.

Technologies

S.L.W.3 – The SLW3 system developed by X-Dial provides fast, micrometre-precise fastening. The compact mechanism is simple to operate: press the button to release the closure step by step, or lift it to open the shoe immediately.

MORPH carbon-fibre composite sole – This sole has a stiffness index of 13. Its anatomical shape and material composition provide a balance of comfort and performance.

SPEEDPLAY adapter (optional) – Developed and patented in collaboration with Speedplay, this adapter reduces the distance between the foot and pedal. It is 0.5 mm thick, compared with 3 mm for traditional Speedplay adapters. The adapter is designed for efficient power transfer to the pedals. The nylon adapter with a thin aluminium plate is 8.5 g lighter and conforms to the shape of the sole. This keeps the distance between the foot and pedal minimal in every position, without the extra space and weight associated with systems without adapters.
