This ultralight triathlon elite shoe was designed for performance and speed, on the bike as well as in transition. The Carbon HM Air Lite outsole and 4.3 mm carbon platform provide excellent power transfer and ventilation. For a fast and efficient transition, a woven puller holds the shoe in a horizontal position on the bike, a velcro tab keeps the closure strap open and a stiff rear puller is easy to grab and pull. The Power Flex closure system offers reversed straps that enhance support without pressure points while allowing a fast transition. The lightweight sandwich mesh upper dries quickly and provides ventilation, so your feet stay dry and comfortable. ELITE FIT.
