With the Tri X-Speed II Shoes, Louis Garneau delivers competitive, race-oriented technology that doesnt cost a fortune. The Ergo Air II nylon outsole works in concert with the Ergo Air EVA insole to channel air through the entire shoe to keep your feet cool and dry. The Ergo II provides excellent rigidity for efficient pedaling and it is compatible with three-bolt road cleats. Louis Garneaus HRS-80 retention system eliminates heel slippage, while the Power Flex closure system uses a reversed hook-and-loop strap to comfortably secure your foot, and it can be easily adjusted while youre on the bike.
