Louis Garneau's Carbon LS 100 Women's shoe offers lightweight, pro level performance at a price that doesn't break the bank. The new HM Air Lite carbon fiber outsole provides the perfect balance of lightness and rigidity, which results in more efficient power transfer with each pedal stroke. For the uppers, Louis Garneau uses a durable synthetic leather with mesh ventilation to keep your feet dry and comfortable. The shoes feature Garneau's HRS 100 technology, which comfortably secures your heel to prevent slippage, and the BOA L4 system and a single hook and loop strap let you dial in the perfect fit. Garneau also includes the COOLMAX Ergo Air Cool Stuff blue and Hot Stuff red insoles. The Carbon LS 100 Women's Shoes are compatible with three hole cleat systems.
