Another Champion System exclusive! The CS Elite Pro Sock combines the comfort of our classic cycling sock with the aerodynamics of a lycra upper. The base of the sock is made from the classic wicking fabric but the ankle is all lycra.  Why a lycra ankle?  A lycra ankle is more aerodynamic, allows for full sublimation printing so any design is possible, and the best part….it looks very pro!  A silicon gripper holds the sock securely on your ankle so it does not slip down.
