The brand new Pro Racing Sock Bike have been completely redesigned to improve 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 to keep feet cool and dry at all times. The redesigned, wider toe box also offers improved proprioception while pedalling. Our signature metatarsal support provides a secure fit, promotes circulation and prevents the fabric from twisting or folding: no more hot spots or irritation on long rides. Two rows of 3D.dots reach halfway up the Achilles tendon and provide additional support when you get out of the saddle. In addition, a row of the brand new Flat.Dots provides additional ventilation. Under the foot, a pattern of 3D.Dots and Flat.Dots provides additional support in the shoe as well as a light micro-stimulation that activates venous return and delays fatigue. The sides of the sock feature brand new Aero.dots technology from the ankle to the shaft, which directs airflow to reduce turbulence at the back of the sock and reduce drag as speed increases. The high cuff has been specifically designed to meet the demands and aesthetics of cycling while complying with UCI limits. The stylish tab on the back of the sock adds a touch of class. After hundreds of kilometres of testing on the road, we're sure this will become your new favourite sock: more style and performance in the peloton, in the breakaway or simply on the Sunday group ride.
