Louis Garneau's Carbon LS-100 shoes combine power, comfort, lightness and an elite fit you'll love. The custom feel is courtesy of the synthetic-leather/mesh uppers that form to you and breathe, while the Boa L4 closures let you quickly dial in and fine-tune the fit of the entire shoe, even when you're riding. Garneau's rigid and ultralight Carbon Composite HM Airlite soles are only 4.3mm thick, keeping you close to the pedals for awesome power, while Garneau's HRS-100 polymer heel-retention system and anti-slip spandex adds efficiency by locking your feet in place. There are also built-in air channels for comfort, plus toe and heel tabs for durability and traction. These sweet shoes also come with 2 pairs of Garneau's Ergo Air insoles, one with their Ice-Fil technology for hot days and one for the cold, too!
