While some shoe makers view comfort as an afterthought to rigidity, the Fi’zi:k R3 Donna Shoes strike the balance between them. This doesn’t mean that the R3 forgoes a carbon fiber outsole or stiff upper, not even close. Instead, Fi’zi:k studied how to integrate each portion of the R3 in order for them to work cohesively. As a result, you get a shoe that operates as a dynamic system, not a long independent string of features. The R3 Donna features two hook-and-loop straps along with an aluminum, ratcheting buckle.

To further control slippage, the R3 Donna has shaped the heel cup at the aft position of the shoe. This feature keeps the foot in the perfect position on hard up-strokes and while climbing out of the saddle. As a result, you’re powering the pedals comfortably and efficiently. This has been further heightened by a variable stiffnes…
