Silca Aero Race Sock Description:

The goal with the Silica Aero Sock 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 that matches the aerodynamic performance of ribbed lycra cuff socks while retaining all of the features you demand from a cycling sock.

Custom knitting machinery allows Silca to produce a sock with a 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 compared to standard socks and equal to ribbed lycra socks of similar height.

Silca aero socks are knit from Q-Skin, a silver ion-infused polyamide that is anti-bacterial, odor resistant, and more importantly, has better softness and moisture control than any of the yarns commonly used to knit socks. Not only are these socks fast, but they're also the most comfortable sock you've ever worn. 


  • Q-Skin antimicrobial polyamide is extremely comfortable
  • Turbulators woven into the sock truck manipulated air flow for less drag
  • Seamless toe box reduces irritation
  • Odor-killing properties extend the lifespan of the socks
  • Saves riders 4-8w over traditional socks


  • Season: Cool Weather
