R2 Aero Black

Bringing together the technologies of our highest performing sock models, the brand new Aero Sock takes multisport performance to a whole new level with air-defying speed. Tested and optimised in the wind tunnel, the front fabric features structured lines to increase boundary layer (surface) turbulation and save over a minute over a 180km Ironman bike ride. Our brand new Aero.dots build a line from the malleolus to the seam, directing the airflow to reduce turbulence at the rear of the sock, decrease drag and save a few more watts. The foot structure follows the design of the Ultralight running sock, with featherweight, sweat-wicking mesh for optimal ventilation and thermoregulation in hot conditions.
