The brand new Pro Racing Sock Bike has been completely redesigned to enhance aerodynamics and comfort. They now offer even more support and ventilation for long days in the saddle. A striped fabric around the foot and on the back of the sock quickly wicks away sweat and moisture, keeping your feet cool and dry at all times. The newly designed, wider toe box also provides improved proprioception while pedaling. Our signature midfoot support ensures a secure fit, promotes blood circulation, and prevents the fabric from twisting or folding: no more hot spots or irritation on longer rides. Two rows of 3D.Dots extend halfway up the Achilles tendon, providing additional support when you stand up. In addition, a row of the brand new Flat.Dots offers extra ventilation. Underfoot, a pattern of 3D.Dots and Flat.Dots provides additional grip in the shoe as well as a light micro-stimulation that activates venous return and delays fatigue. The sides of the sock are equipped with the brand new Aero.dots technology from the ankle to the shaft, directing airflow to reduce turbulence at the back of the sock and decrease drag as speed increases. The high cuff has been specifically designed to meet the demands and aesthetics of cycling while adhering to UCI limits. The stylish tab on the back of the sock adds a touch of class. After hundreds of test kilometers on the road, we are confident that this will become your new favorite sock: more style and performance in the peloton, in breakaways, or simply on your Sunday group ride.
