The brand new Compressport Aero Sock takes multisport performance to a whole new level.

Tested and optimized in the wind tunnel, the front fabric features structured lines to increase boundary layer (surface) turbulence and save more than a minute during a 180km Ironman bike ride.

The new Aero.dots form a straight line and direct airflow to reduce turbulence at the back of the sock, reducing drag and saving a few more watts .

The foot structure follows the design of the Ultralight running sock, with feather-light, sweat-wicking mesh for optimal ventilation and thermoregulation in warm conditions.
The revised, wider toe box provides increased comfort, while a special knit around the heel provides soft support when the pace picks up. Light arch support prevents the fabric from twisting and irritating, with extra terry cloth padding over the big toe to protect you from black nails and bruises. Under the foot, a smart pattern of 50% 3D.Dots and 50% Flat.Dots provides shock absorption and grip in the shoe.

It also provides gentle microstimulation to increase venous return and delay fatigue, while also improving ventilation as air circulates between the dots. At the back of the sock, ultra-light mesh provides thermoregulation without adding weight and a full Achilles stripe in DOT technology provides reassuring support in all disciplines.

The cut is higher than that of the trail and running models for optimal aerodynamic performance while still within UCI limits . Silicone inserts around the seam prevent the material from sliding down when you switch from bike to run. The revolutionary Compressport Aero Sock is the fastest sock of the bunch, from your local triathlon to the lava fields of Kona.
