Improving upon the already unbelievable R3 Donna Women’s Cycling Shoe isn’t an easy thing to do. Leave it to the folks at Fizik to make great even greater. At the heart of the new shoe is the unbeatable precision of the Boa dial-in closure system. This closure system makes dialing a perfect fit easy on the Fizik, even if you need to make micro-adjustments on the fly.
The R3’s closure system starts with a conventional hook-and-loop strap close to the Donna toe for near-infinite forefoot width control. Moving up the front of the foot, the Boa Cable dial-in closure system snakes its way through four separate anchor points for complete control all the way up to the tongue. For an extreme control over volume, or simply to efficiently clean the inside of the shoe, Fizik designed the tongue pad to be fully-removable.
To further control slippage, the R3 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 stiffness sole construction. The base layer is an ultra-stiff carbon fiber-reinforced plate.
They went above and beyond to make the R3 extremely breathable. This might not be obvious, given the R3’s lack of traditional mesh ventilation. However, the uppers of the shoe feature their own Microtex microfiber—the same material used on the saddles and bar tape. This material keeps your feet breathing and comfortable on long summer days in the saddle. And for the insole, the R3 includes their own Cycling Insole. And while its not custom moldable, it does incorporate a thoughtful design that assures comfort by absorbing road vibration and supporting your arch system.
