Frequently Asked Questions (FAQ)

1. How do aero socks save watts and improve efficiency?
Aero socks reduce drag by creating a turbulent airflow layer around your legs, minimizing turbulent wake. Castelli Fast Legs save ~2 watts at 50 km/h, while Aerocoach Flow Guards save up to 5.3 watts at 45 km/h, translating to seconds saved over race distances.

2. Are aero socks worth it for triathlons?
Yes! Even small watt savings, like 2-5 watts, can add up over long bike legs, saving seconds or minutes in non-drafting races. They’re a cost-effective upgrade compared to wheels or frames.

3. How do I choose between Castelli Fast Legs and Aerocoach Flow Guards?
Castelli offers a smoother ankle transition and breathability for shorter races, while Aerocoach provides higher watt savings for time trials or longer efforts. Check sizing or consult our team for the best fit.

4. Are these socks comfortable for long rides?
Castelli Fast Legs are comfortable up to 6 hours but may feel tight due to the gripper; Aerocoach Flow Guards are compressive but breathable, though the ankle seam may be noticeable. Test for your comfort.

5. Are these socks UCI-compliant for racing?
Yes, both Castelli Fast Legs and Aerocoach Flow Guards meet UCI sock height regulations, making them legal for competitive cycling and triathlon events.

6. How do I care for aero socks to maintain performance?
Wash gently in cold water and air dry to preserve the textured fabrics and silicone grippers. Avoid high heat to maintain elasticity and aerodynamic properties.
