Assos RSR Speed Booties S11

Assos RSR Speed Booties S11 Info

The Assos RSR Speed Booties S11 are World Tour developed aerodynamic overshoes built for racing at the highest level. Refined through wind tunnel testing and peloton feedback, the S11 update adds silicone grip at the ankle to maintain a secure, UCI-legal fit without sacrificing speed. The upper cuff features integrated grip for stability, while the raw Zero Cuff eliminates bulk and drag from closures. Aerodynamic 550CX warp-knit textile wraps the ankle and heel for reduced turbulence, and ultra-elastic Eva Kant material covers the toe and forefoot in a low-profile, drag-reducing shell. The RSR Speed Bootie is Assos' most race-focused overshoe, designed as a true second skin.
