The design started with a stiff nylon/fiberglass ventilated outsole. This feature allows the athlete to have an easy, efficient pedal stroke without losing any energy due to a loose outsole like the ones found on normal running shoes. Multiple air channels are located in the outsole for constant airflow. Moisture is also evacuated on top as many areas of the Actifly are covered with the same mesh fabric used for Garneau's renowned triathlon shoes. These were made to dry out fast, so why change a winning formula? We've also used our most breathable insole to maximize the Actifly's airflow.
