Assos Equipe RS Rapidfire Chrono Booties

Aerodynamic shoe covers that we tested and refined with our WorldTour riders, these booties rewrite the manual for second-splitting speed.

We've been pioneering aerodynamic cycling equipment since Tony built an aero carbon frameset in the '70s. These booties—with their a second-skin fit, validation in the wind tunnel, and the approval of our WorldTour riders—are the latest example of ASSOS putting on a clinic of aerodynamics for the cycling industry to (eventually) emulate.

EVA KANT's high-stretch qualities recommend it for aerodynamic applications, but it's also wind- and waterproof for when race day arrives with threatening clouds. Our high-stretch Cube textile runs up the ankle with a jacquard 3D-structure weave that melts into place across your shoe, sock, and leg.

We have a fit called aeroFit. These are the avatar of that fit. From the impossibly thin cuff to the silver bullet toe, these booties define aerodynamics.
