Reach peak performance in the Ruby Cycling Shoes – engineered to help you step it up a notch. The upper is constructed in engineered synthetic leather and breathable cycling mesh, delivering an excellent balance of comfort, support and airflow. The outsole is made with Ergo Air® II reinforced nylon and features a patented ventilation system. The shoes tighten with a BOA adjustment system and hook and loop fastener foot closure – with the single-rail dial delivering a quick attachment, evenly distributed pressure and power retention. The thermobonded upper is seamless for aerodynamic advantage and the elimination of pressure points, while the total weight of 272g makes this an impressively light design for serious riders. You can tweak the performance of the shoes thanks to the interchangeable Ergo Air®, Cool Stuff and Hot Stuff insoles. The shoes are optimised for use with SPD-SL, SPD, TIME, LOOK and SPEEDPLAY cleats.
