Runs were conducted for a speed range of 30-60kph at 5kph increments to display how guards perform through typical race speeds. A constant cadence of 90rpm was selected for all runs measured by a crank based powermeter.
Both the socks and the guards tested were brand new to avoid any variance in test results that could occour through wear. Tests were conducted over 30 second runs, with any erroneous runs repeated.

Do Calf Sleeves Save Watts?
Yes! At all speeds above 35kph aero calf sleeves saved our test rider Watts. At 45kph - a reasonable average speed for a competitive time trialist, aero calf sleeves saved 2.53W
Since this test, our Pro Socks have been replaced by our Aero-Ish Socks, these are a regular cycling sock with incorporated aerodynamic turbulators. They are not as fast as our full Aero Socks, but they are better suited to non-competitive cycling.
Our Aero Calf Guards Have also been updated to our One Aero Guards and our Neo Aero Guards
