We're betting that even if you've aero-optimized your bike and riding gear, you might have overlooked one other piece of equipment, socks. Now with the Aero Speed Sock from Castelli, you can rest assured that your aero game is covered from head to ahem, toe. Its use of aerodynamic materials and construction techniques are specifically designed for an all-out assault against the wind, clock, and competition, and it'll help you shave crucial seconds during that super important time trial, crit, road or track race.
Starting at the top of the sock, an aerodynamic silicone band keeps the cuff in place with a next to skin profile. The lined lycra upper extends from the top of the shoe to the mid-calf to better manage turbulent airflow and provide a smoother profile for the wind to pass over. For the foot, Meryl Skinlife mesh is utilized and prized for its breathability and keeping your feet cool, perfect for when you're giving it your all during a hot event.
