Silca Aero Socks - Tall | Black

Do SILCA Aero Socks Actually Make a Difference on the Bike?

The SILCA Aero Socks are purpose-built for aerodynamic performance, developed using wind tunnel and CFD testing to determine the fabric texture and construction that reduces drag at the ankle and lower leg. The socks use a knitted surface texture that trips the boundary layer in a similar way to dimples on a golf ball, reducing the drag coefficient versus smooth-surfaced compression socks in the same speed range typical of road and time trial cycling. SILCA's own testing showed measurable watt savings at competitive speeds, making these one of the few sock-level marginal gains claims that has supporting data behind it. The Tall height covers the lower leg fully, which is where aerodynamic gains at the ankle are most significant.

The Black colorway is the most versatile option, pairing cleanly with any kit color and looking sharp at races, group rides, or on the trainer. Made from a moisture-wicking performance fabric blend. Available in standard sizing. If you're already wearing a skinsuit and aero helmet but haven't addressed socks, this is an easy, cheap watt to recover. Sold as a pair.
