The r1b uomo relies on fit and high-end materials to become an indispensable part of kit. This year, fi'zi:K replaced last year's kangaroo leather uppers with its trusted microtex material. If you're a loyal r1b fan, don't worry; the synthetic material has already earned its stripes on fi'zi:k's extensive line of saddles and other shoes, so rest assured that it's worthy of a shoe of the r1b's Caliber. With an asymmetrical cut and dual boa dials providing limitless potential for fit adjustment, the shoes' one-piece uppers will wrap around your feet in a way not unlike the post-ride burrito you dream about to get you through your last climb of the day. Plus, fi'zi:K took the time to carve tiny, precise pinpricks throughout the shoes' uppers to let the shoes, and your feet, breathe on hot days. Fi'zi:K didn't stop there either. Other fit details, like an adjustable heel cup for more consistent power transfer and fi'zi:k's careful volume control design work to achieve a nearly custom fit that goes beyond simpler, less precise models. Along the bottom, a uni-directional carbon fiber sole anchors the shoe, promising the kind of snappy power transfer that has earned the r1b uomo its well-deserved presence in the Peloton. Take a closer look at the soles and you'll notice a complex, and meticulous arrangement of vents, capably managing airflow without inhibiting your aerodynamic efficiency.
