A performance road shoe primed for cold weather, the Nix features an upper lined with a laminate of new, eco-friendly Gore-Tex®, free from damaging PFCs while remaining highly water resistant, windproof and breathable, as well as fleecy Primaloft® insulation to warm your toes.

It is shaped with aerodynamics in mind, with a carbon composite sole that is stiff enough to transfer power effectively to the pedals, though with just enough flexibility to make walking a touch easier. The toe, meanwhile, is reinforced, to ensure you won't have to worry about stones when you're pedalling hard.

With a fit cinched in by Sidi's quick, strong and easy-to-operate rotor closing system and reinforced by the wrapper closure system and Firmor lateral support band, which respectively secure the ankle and anchor your foot, this is an accomplished racing shoe with an added touch of cosiness.
