Assos RSR Speed Booties S11
The Assos RSR Speed Booties S11 are proven at World Tour level racing, a premium overshoe designed for aerodynamic performance, featuring an ultra-sleek second-skin fit that minimises drag on race day. This updated S11 version incorporates a silicone grip at the ankle for a more secure fit, maintaining the bootie’s position at a UCI-legal height even as speeds rise. Developed in collaboration with World Tour riders, the RSR Speed Booties have been refined through wind-tunnel testing and real-world races, ensuring competitive-level aerodynamics maximise your speed and efficiency.
Constructed with advanced 550CX warp-knit textile for the ankle and heel, these booties offer exceptional drag-reducing properties that streamline airflow. The toe and forefoot areas are enveloped in Eva Kant fabric, a highly elastic material that provides a glove-like fit while enhancing aerodynamics. The raw-cut Zero Cuff design eliminates the need for zippers or fasteners, reducing drag and ensuring a seamless connection with the lower leg performance.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
