This is one of our best sellers across all Collections. It was designed by Louis Garneau himself after suffering a lot during the 1984 Los Angeles Olympics because he couldn’t find any technical shoes on the market at the time. And we’ve continued to improve it year after year since then. With a perfect racer fit, the carbon sole maximizes the energy transfer on the pedal and the sleek lines fit the foot perfectly while the perforated inner sole keeps you cool.

To give a break to the 26 bones that squash and squeeze in your foot while you’re riding, we have patented a unique X-Comfort Zone. It’s a small section inside the shoe that can expand up to 5 millimeters to prevent numbness. Without any extension system, the toes end up on top of each other and get numb. Thanks to this innovation, you won’t have to end your ride before you’re done ever again. For great performance, we’ve used a carbon composite sole that optimizes energy transfer on the pedal. We wish you an excellent season! - Technology : RACER FIT: High-performance fit reduces stack height to pedal - Integrated X-Comfort Zone technology with better stretch - Outsole: Patented Carbon Composite outsole - Insole: COOLMAX®: Moisture wicking, breathable and ventilated - Closure System: Boa Li2: mechanism generates higher power with finer resolution - Cleats: SPD-SL compatible with 3 bolt
