veloToze shoe covers have been used by many cyclists for aerodynamic benefits. Our shoe covers are made with unique windproof material to form a smooth snug fit over the dials and buckles of your cycling shoes to significantly minimize aerodynamic drag.
We tested our shoe covers and aero products at Silverstone Sports Engineering Hub in the UK. To simulate a real-life cycling environment, our test was conducted at 40 kph (25 mph) with different yaw angles from -10˚ to +10˚, here are the results in watts.
|Products||Yaw -10˚||Yaw -5˚||Yaw 0˚||Yaw +5˚||Yaw +10˚||Real life condition||% Power Saving|
|Tall 2.0 SC||-1.90||-2.04||-3.91||-4.77||-2.47||-3.61||1.91%|
|Short 2.0 SC w Aero Socks||-4.15||-3.71||-4.46||-2.93||-0.74||-3.97||2.10%|
|Aero Sleeves w Toe Covers||-2.67||-1.86||-1.16||-1.70||-1.86||-1.42||0.75%|

We tested over 5 different yaw angles to simulate what cyclists might typically encounter in the real-world environment. The yaw angle experienced by a cyclist depends on various factors such as wind speed, wind direction, cyclist's speed, and terrain. Numerous studies showed under typical non-extreme windy conditions, a cyclist will experience yaw angles between 0˚ to ±5˚ the majority of the time and up to ±10˚. While it would be nearly impossible to test at every yaw angle, we used the assumption that the cyclist spent 65% of the time at 0˚, 25% of the time over ±5˚, and 10% of the time over ±10˚ to come up with an estimate for "real life condition" to see the potential power saving.
