Silca Aero Socks

Can Silca make an aero sock, that is first and foremost a really good sock  Josh worked with a team in Italy who is quite famous for making the finest socks in the world, and who also has some of the most modern kitting machinery in the world.  The goal was to make a knit sock that won’t fall down, but has a combination of smooth and rough texture to trick the air into flowing around the lower leg more efficiently.  The result is a sock which matches the aerodynamic performance of ribbed lycra cuff socks, while retaining all of the features you demand from a cycling sock.

The technology: Custom knitting machinery allows us to produce a sock with smooth frontal surface where the airflow is laminar, with the addition of 3 rows of turbulators starting just ahead of the flow separation zone.  These turbulators introduce small vortices in the boundary layer which energize the flow and promote flow attachment further around the leg.  More attached flow means a smaller pressure wake behind the leg, less wake = less drag.  4-8 watts drag reduction (when tested at 30-45kph) when compared to standard sock and equal to ribbed lycra socks of similar height
