For rides where we don't necessarily have a set goal in mind, we ride in the Mavic Cosmic Boa Cycling Shoe for a perfect balance of performance and comfort. The nylon and fiberglass outsole, rated right in the middle of Mavic's stiffness index, allows us to put down power when we see a beatable KOM but keeps us comfortable as we spend our ride exploring new areas. With the perforated synthetic leather composite upper construction, our feet are thankful for the extra airflow to keep them cooled off on a hot day, while the L6 BOA Fit System and hook-and-loop strap ensure optimal comfort and security.
