Louis Garneau's feathery Tri X-Lite Shoes are the perfect choice for zooming through your bike leg and transitions alike! Garneau's rigid Ergo Air Carbon Composite soles are a mere 4.3mm thick for optimal power transfer and sport multiple vents for superior airflow. To make transition a breeze, there are supports to hold the shoes horizontal for quick entry, Velcro tabs that keep the closure straps open and ready, supportive, offset Power Flex straps that are reversed for speedy on/off, and large, rear loops for quickly sliding the shoes on. You'll also love Garneau's HRS-100 polymer heel-retention system and anti-slip spandex that add efficiency by locking your feet in place. And, for awesome comfort with all that speed, their quick-drying mesh uppers and CoolMax insoles offer excellent ventilation after the swim.
