Silca Aero Socks - Tall | Black

What makes the SILCA Aero Socks Tall faster on the bike? The SILCA Aero Socks Tall are built to be a genuinely great sock first, with real aerodynamic gain on top. SILCA worked with a renowned Italian sock maker and custom knitting machinery to combine a smooth frontal surface, where airflow stays laminar, with three rows of turbulators placed just ahead of the flow-separation zone. Those turbulators energize the boundary layer and keep airflow attached further around the leg, which shrinks the pressure wake behind it. Less wake means less drag: SILCA measured a 4 to 8 watt reduction at 30 to 45kph versus a standard sock, matching ribbed lycra socks of the same height. The 19.5cm cuff sits right at the UCI limit, putting the textured surface where it does the most work. They are knit from Q-Skin, a silver-ion-infused polyamide that is anti-bacterial, odor resistant, and softer with better moisture control than the yarns normally used for socks, with no toe seam for all-day comfort. The Black colorway is the most versatile of the lineup, pairing cleanly with any kit and looking sharp at races, on group rides, or on the trainer. If you are already running a skinsuit and aero helmet but have not addressed your socks, this is an easy, cheap way to recover a few watts. Sold as a pair.
