If you are looking to minimise your CdA (coefficient of aerodynamic drag), save watts and go faster, this overshoes are for you.
Perfect for riders racing under UCI rules, as they are within the length limitations allowed.
Redesigned from our previous generation, our UCI Aero Overshoes are extremely light featuring a smooth fitted surface material which covers the full shoe, eliminating any drag. The top part of these overshoes are in aero flow fabric, featuring a new anti slip rubber on the inside.
Watts saving @45km/h approx 5-10W.

Fitting Instructions
Please note that as they are an aero product they will be tighter to put on first time, after a couple of wears the rubber material will stretch slightly making it easier. 

Please follow the instruction and watch the fitting video:

1- With shoes on, turn the lycra fabric completely inside out until you can see where the seam meets the rubber.
2- Place your shoes inside all of the way to the toe and pull the rubber all of the way back to cover your heel.
3- Finally unfold the lycra fabric and place it into position on your leg.
