Castelli Fast Feet TT Shoe Covers

£0.00

The Castelli Fast Feet TT Shoe Cover is designed for maximum aerodynamics in time trialling, within the limits of the UCI rules.

Castelli developed it through CFD analysis followed by extensive fabric and on-bike wind tunnel testing. The smooth silicone-coated foot portion smooths out the shape of the foot, while the grooved leg portion helps to detach the air as it flows around the leg. The shoe cover is cut high, reaching to the calf.

There's no reason not to wear it on the road, but its gains are maximised at TT speeds.
