Description:The Course Air Lite road cycling shoes are our lightest shoe yet. The Carbon HM X-Lite outsole with titanium inserts is ultra-light and rigid for better power transfer, and the 4.3 mm carbon platform brings your feet closer to the pedal for even more power. The BOA IP1 attach system offers infinite levels of micro-adjustment, creating a perfect fit. The Louis Garneau patented air channel system intakes air at the front and channels it through the shoe where it exits at the back, creating an airflow inside the shoe that keeps feet cool. Weighing barely 7.8 oz (222 g) for a size 42 shoe, the Course Air Lite cycling shoe offers optimal comfort, spectacular performance and the highest ventilation for the least weight.
