Two years ago Josh convinced one of our ProTour teams to move every rider to aero socks for every event. The savings from aero socks are one of those crazy things in cycling that we mostly still can't believe, but repeats in the data every time.. 8-12 watts of savings at 50kph, unbelievable.
Little did Josh realize that he was about to be responsible for a mutiny among the riders. Early in the spring classics, the problems began, the ribbed lycra cuffs which lead to the improved aerodynamics would fall down.. constantly.
Thus started the mission. Can we 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 compared to standard sock and equal to ribbed lycra socks of similar height
SILCA aero socks are knit from Q-Skin, a silver ion infused polyamide which 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, they're the most comfortable sock you've ever worn.

I've had previous pairs. My all-time favourites - comfortable on long rides, work with my feet and shoes, seem to survive the wash. Can't say for the aero gains, but I FEEL faster just putting on those cool chevrons.

Why Make Them so Short?
If the intension is to make the leg more aerodynamic why would you make the length so short? I’m 6’ and wear an XL sock. They could be 2-3” longer and still be within UCI limit. Check the comparison between a Rapha sock and the Silca.

We did not set out to create the most out and out aero sock, rather one that is comfortable to wear everyday and still offers an aero benefit. We have also launched a taller version for customers looking to push the UCI limits.

Ultra comfortable!
These are not just the most comfortable cycling socks I own, they’re the most comfortable socks I own PERIOD. Can’t speak to their aero benefit as I’m stuck indoors on the trainer. Sizing chart was useful and accurate.

Comfortable and effective!
These socks make you so fast! I noticed the difference immediately. Will be buying more pairs of these and using them daily. They improve all aspects of aero efficiency. They're quite comfortable and breathable. Perfect for the avid cyclist looking to improve and snag those Strava PR's.
