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.
