The RSR Speed Booties have earned their place on the WorldTour podium, having been tested, refined, and raced by elite athletes since their earliest prototype days. Now in their S11 generation, these aerodynamic overshoes continue to set the standard for performance, combining wind tunnel-proven drag reduction with real-world racing results. The latest updates include a refined ankle design featuring integrated silicone grip across the upper cuff. This ensures the booties remain securely in place while maintaining a UCI-legal height, offering riders both compliance and confidence in the heat of competition.

The booties are constructed with the innovative 550CX warp-knit textile, a fabric that conforms seamlessly around the ankle and heel. This material is engineered specifically for its drag-reducing properties, providing an aerodynamic upgrade through a smooth, second-skin fit. Complementing this is the ultra-elastic Eva Kant textile, which wraps the toe and forefoot for additional aerodynamic shaping. Together, these materials reduce surface turbulence and help maintain airflow, contributing directly to performance at speed.

Fit and finish are equally refined. The RSR Speed Booties showcase Assos’ aerodynamic racingFit, which eliminates excess bulk and conforms precisely to the rider’s foot and lower leg. The Zero Cuff construction—raw-cut and free of zippers or hook-and-loop fasteners—further reduces drag while ensuring a sleek, uninterrupted silhouette. Every detail has been considered in pursuit of maximum speed and minimum resistance, from material choice to closure design.

Whether you're chasing time trial victories or eking out marginal gains in a sprint finish, the S11 RSR Speed Booties deliver unmatched aerodynamic performance, secure fit, and pro-level construction. Designed for racers who demand the highest standard, they represent the cutting edge of cycling apparel innovation.
