Aero socks are THE most effective upgrade you can make in cycling. It's not even close.
For 1% of the price of a deep section aero wheel set, you can save more Watts in an instant.
It's hard to believe just how much of a difference they make so we've crunched the numbers for you.
In a product testing session at the Silverstone Sports Engineering Hub, we compared our Aero Socks to a standard set of non-aero cycling socks - our Pro Socks. These are a high quality, breathable, mid length sock - but they aren't aero.
We tested both socks on our test rider, Jean Spies - South Africa's Olympic Track sprinter at 5 kph increments from 40-75kph (Jean's top speed on the track).
30 second runs were conducted at each speed with a constant cadence at 0-degree yaw.
