The R3B road cycling shoe is built with perforated Microtex, features a carbon-reinforced outsole and Boa IP1 closure system for a great fit and pedaling efficiency. Handmade in Italy out of synthetic Microtex, they offer a narrower toebox than the range-topping R1B, with sizing about half a size larger than a comparable SIDI shoe.
