Garneau's Course Air Lite road cycling shoes are the lightest shoe in the Louis Garneau lineup. The Carbon HM X-Lite outsole with titanium inserts is ultra-light and rigid for unbeatable power transfer, and the 4.3mm carbon platform brings your feet closer to the pedal for lower stack height and a better connection to the bike. The BOA IP1 attach system offers infinite levels of micro-adjustment, creating a perfect fit. The Louis Garneau patented air channel system pulls in air at the front and channels it through the shoe where it exits at the heel, creating an airflow inside the shoe that keeps feet cool. Weighing barely 7.8oz (222g) for a size 42 shoe, the Course Air Lite cycling shoe offers optimal comfort, spectacular performance, and the highest ventilation, all at an incredible low weight.
