With their development in the wind tunnel plus feedback and use by Pro riders in the WorldTour, you can be confident the RSR Speed Booties deliver meaningful gains when you're seeking a competitive advantage over your rivals. Starting at the ankles and cuffs, Assos use their aerodynamic Windchannel Stripes material. This Lycra® blend warp knit gives an incredibly snug and smooth fit with little to no creasing. As speeds increase it reduces drag to less than that of just your bare skin. The Zero Cuff design also gives an incredibly smooth fit, eliminating the ridge between shoe cover and skin. Over the front of the foot, you'll find EVA KANT material. The high-stretch characteristic of the fabric makes it ideal for aero applications, keeping the fit with your cycling shoes as snug as possible. And with wind- and waterproof protection, racing fast in inclement weather presents no problems.
An evolved version of Assos' race-proven shoe covers. Developed with feedback from their professional riders and ridden to WorldTour victory since they were merely prototypes Ever since Toni built an aero carbon frameset in the ’70s ASSOS has been at the leading edge of cycling aerodynamics. 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 in aerodynamics. For the TARGA evolution we updated the heel and cuff material for an even more streamlined aerodynamic fit.
