Fully UCI Legal, the Rule 28 Aero Socks are the fastest on the planet - and that's not hyperbole. The brand's flagship product provides the best bang for your buck when it comes to aerodynamics, making these socks an essential addition to your race day kit.
The fit of aero socks around the calf is key to how they perform and their efficacy. 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.
Measuring calf circumference will help to determine which size will provide the most aerodynamic benefit for you. When your calves indicate you are a smaller size than your shoe size, we recommend sizing down.
