Sink your fangs into fit.

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. The Fizik R5 Donna Boa Women’s Shoe takes advantage of the incredible precision of the Boa system while maintaining extraordinary ventilation, tough durability, and impressive light weight.

The R5's closure system starts with a conventional hook-and-loop strap close to the 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 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, Fizik 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. Underfoot, the R5 makes use of a carbon-reinforced nylon outsole. And while this keeps costs down, it doesn't inhibit either comfort or power transfer. In fact, the R5 retains a low stack height and a high level of rigidity. Fizik has also engineered-in trace flexibility, so the outsole drives power directly to the pedals while allowing enough movement to guarantee comfort after 80 kilometers.

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 summer days in the saddle. And for the insole, Fizik included its own Superlight Insole. And while its not custom moldable like with the R1, it does incorporate a thoughtful design that assures comfort by absorbing road vibration and supporting your arch.

Clipping in

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I just bought these shoes and for some reason I cannot clip-in, or when I do the cleats slide out very easily. My boyfriend bought Fizik R1s a couple weeks ago and complained about the same issue (I thought he was crazy). Anyone else experience the same issue? FYI-I have Ultegra pedals and my BF Dura Ace.

Cute and Great Value

    I am new to road biking so I didn't want to invest too much in my first pair of road shoes, but for the price and features these really are a steal. I love that they are black so they do not get dirty easily - three months later they still look almost new. The boa closures take half the time to put on compared to my boyfriend's caliper buckle sidis, and they look feminine and cute. When I called to check on the sizing since there are two different size charts posted, Backcountry was more than helpful. I do recommend measuring your foot in mm to get the right fit.

    Cute and functional

    Absolutely love these shoes. I checked the sizing 4 times before purchasing since they called for a smaller size than some of the other road shoes out there. The size chart posted in the comments is the right one and the shoes fit perfectly. Not only are they functional and easy to put on/take off because of the boas but they are cute too!

    Thanks for the reviews Laura! Super helpful to get this feedback out to the community.
