The Neo Aero Socks use our dual layer aero technology and are the fastest socks we have ever tested, saving 12.11W at 45kph vs our previous generation of socks. Yes, you read that right. Our newest generation of aero socks utilise fabrics that until now have only ever been used in bespoke projects for the world’s most elite riders. This new generation of fabric is also lighter and grippier, which improves grip and comfort in hotter riding conditions. When is comes to £ per Watt saved, aero socks are the best value upgrade you can make in all of cycling; delivering greater drag reduction than a top-of-the-line aero wheelset for less than 1% of the price. The fit of aero socks on the calf is a key part of how they perform. Our aero socks are designed for a mid-range calf size. If you have thin calves and are towards the bottom range of each size, we recommend sizing down to avoid issues with grip PLEASE NOTE: The gripper on these socks comes with a protective coating applied to prevent it sticking to itself. Please wash the gripper before use to ensure good grip on the leg. If you have any questions regarding sizing, please contact us at [email protected].
