Assos RSR Speed Booties S11 Info
The Assos RSR Speed Booties S11 are World Tour-developed aerodynamic overshoes built for riders who treat every watt as non-negotiable. Refined through wind tunnel testing and peloton feedback, the S11 update combines ultra-elastic Eva Kant material over the toe and forefoot with aerodynamic 550CX warp-knit textile at the ankle and heel — together forming a low-profile shell that sits close to the shoe and reduces turbulence where it matters most.
A raw Zero Cuff design eliminates the bulk and drag that closures typically introduce, while integrated silicone grip at the ankle cuff keeps the bootie locked in position through hard efforts without adding volume. The result is a UCI-legal fit that wears like a second skin — secure enough for criterium racing, refined enough for the long haul of a road stage.
