Cycling shoes Northwave Sonic Plus Road (black / grey)

The Northwave Sonic Plus Road road cycling shoes feature a Morph sole with the Powershape system, which supports the arch of the foot. Air channels in the sole and ventilation openings in the upper help promote airflow. The asymmetric upper is made from composite materials. The X-Dial SLW3 closure system allows precise adjustment of the fit.

Technologies

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

MORPH carbon-fibre composite sole – The anatomically shaped sole has a stiffness index of 13 and balances comfort and performance.

SPEEDPLAY adapter (optional) – In collaboration with Speedplay, Northwave developed and patented an adapter that 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 stated to provide maximum power transfer to the pedals. The nylon adapter with a thin aluminium plate weighs 8.5 g less and conforms to the shape of the sole. As a result, the distance between the foot and pedal remains minimal in every position, without the extra space and weight required by systems without adapters.
