DeFeet Evo Disruptor

In July of 2019, the Disruptor was field-tested on the road with World Tour team, Deceuninck-Quickstep, while racing the Tour de France and were worn by Julian Alaphilippe whilst he was in the Yellow Jersey.

DeFeetʼs newest aero sock technology, the Evo Disruptor, is thin, compressive and lightweight. The construction is defined by the finely knit fabric containing low profile, vertical striations to optimize aerodynamics. An additional amount of Lycra is added to the composition to lend support for your feet and securely keep the sock in position. The sock is smooth on the skin, dries fast and features a no feel toe closure. The minimal profile does not take up extra space inside modern cycling shoes. Disruptor socks are ideally suited for time trials and road races in warm to hot conditions. 

Independently tested in the wind tunnel on elite riders, Disruptor socks effectively disrupt the critical boundary layer of air as it passes to reduce drag at a normalized speed of 48kph (29.8mph). Defeet’s testing was performed at the UCI mandated cuff height. UCI regulations state the cuff placement is at mid-calf and is calculated as the halfway point measured from the lateral malleolus to the fibula head.
Our recorded data sets with live riders at the 0°& 5° yaw indicated an average reduction of 8 watts when compared to standard bare shaved legs and outperformed other aero socks available in the road cycling market.
