Fast just got even faster. Our all-new One Aero Socks save 10.45W at 45kph vs our previous generation. 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 fabric is also lighter and grippier, which aids with grip and improved 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. These 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.
