What Our Gearhead(R) Experts Are Saying:"I've been riding the Cosmic SLR on long training days and race efforts alike, and the dual BOA L6 dials make it easy to fine-tune upper and lower fit zones independently without stopping. The Matryx upper stays genuinely cool on hot climbs, and the carbon composite sole feels stiff and direct underfoot whether I'm sprinting or grinding out the final miles of a long ride."The gap between a good ride and a great one often comes down to the small margins, and the Mavic Cosmic SLR Cycling Shoe is engineered to close them. From the opening miles of a sportive to the final climb of a gran fondo, this shoe keeps comfort and efficiency running in parallel so nothing gets in the way of the effort. Mavic built the Cosmic SLR around a Matryx(R) woven upper that combines polyurethane structure with high-tenacity fibers for a fit that feels precise without creating pressure points. Front vents and PU-coated yarns keep airflow moving through the hottest parts of a ride, and the dual BOA(R) L6 Fit System allows independent adjustment across two zones so the shoe conforms exactly to the shape of each foot. Underfoot, the composite nylon carbon fiber sole delivers a stiffness rating of 80 out of 100, translating pedaling input into forward motion with minimal energy lost. Rubber heel pads add a touch of grip and durability for the moments between the bike and the start line.
