Designed for road racing at the highest level, the Vento Powerstrap R2 Aeroweave's structure and breathability give us the competitive edge and is the lightest and stiffest shoe in Fi'zi:k's line. The Aeroweave upper creates an open weave that is both durable and breathable, while the Powerstrap closure provides a wrap-around secure fit at a light weight. Fi'zi:k's R2 unidirectional carbon sole is the stiffest from Fi'zi:k, making sure every ounce of effort transfers from foot to crank. The cleat mounting on the R2 is set back slightly, closer to the midfoot, which allows for more ergonomic cleat position for more aggressive riding.
