An ill-fitting bike is a bad thing. When your ride mileage routinely measures in the triple digits, however, an ill-fitting shoe may be worse. Too tight and circulation is cut off; too loose and slippage causes painful blisters. Skiers and snowboarders have known for years: for a perfect fit almost nothing beats the Boa system.

And on the topic of comfort, Fizik went above and beyond to make the R5 extremely breathable. The R5 features Fizik’s Microtex for the support structure of the uppers and nylon mesh for the ventilation windows. Together, these materials keep your feet breathing and comfortable on long su…
