Red is the new fast.

The Fizik R1B Uomo Boa Limited Edition Men's Cycling Shoe carries a pedigree that's seen time in everything from time trials to spring classics to weeklong stage races at the highest level of our sport. This particular version takes the standard R1B and pairs it with an eye-catching colorway that'll add a pop of intrigue to any race kit.

The R1B incorporates Fizik's Volume Control system to prevent hot spots with two independently wired Boa IP1 dials, an adjustable heel cup, and a pull-over flap that's shaped to wrap the foot rather than just strap it in. This partitioned adjustment construction is fairly standard with most high-level shoes these days, but the Volume Control design really departs from other shoes at the upper Boa dial. It not only wraps the mid- and upper-foot for a secure fit from afore, but it also adjusts from astern, dialing the heel cup's fit to ensure the kind of customizable security that keeps your feet in place for more efficient power transfer throughout your pedal stroke and less danger of heel irritation and blisters.

Instead of its predecessor's Kangaroo leather, the R1B's upper is Fizik's all-purpose microtex synthetic. It's the same, well-tested material found across the manufacturer's shoe and saddle lines. Barring a series of tiny, ventilating perforations, the uppers are a single, clean piece, adding to the shoes' understated profile and validating the aesthetic praise they received in virtually every publication that wrote them up after the latest round of industry trade shows.

  • A race-ready road cycling shoe
  • Stiff, responsive carbon sole with cooling vents
  • Highly durable, ventilated synthetic uppers
  • Adjustable heel cup improves power transfer
  • Streamlined, next-to-skin fit from dual Boa dials
  • Fizik proves that subtle form can coexist with pronounced color

Are these shoes good for wide feet? Especially the front part of the foot.

Hi Beverly,

These shoes are not going to be "wide" in the toe box, and most experience they run smaller than normal.

I would suggest looking at either Shimano, or maybe the Sidi mega models, as they will offer more room in the toe box.

Please feel free to reach out to me directly with any other questions you may have.

Thank you

  • Fit: True to size

When it comes to shoes I have serious issues. If there is the littlest imperfection in the fit it finds a way to explode onto my foot somewhere. Having fought plantar fasciitis a few years ago I have learned the hard way that one of the most important pieces of equipment for a rider is undoubtedly shoes. The new fizik R1B is not only one of the most comfortable cycling shoes I have worn, but one of the most comfortable shoes I have worn.
Fizk calls it Volume Control technology with some micro-adjustable Boa IP1 closure controls...I call it a comfortable shoe.
As soon I slide my foot in I knew it was going to be a good fit, even without putting in my own insoles. Surprisingly the insoles are really good with a good amount of arch support and dense cushion. Nothing I hate more than spending a few hundred dollars on shoes and the first I do is throw the footbed away. Not saying these shoes will work for you, everyone is different when it comes to shoes, but I have worn a lot of different shoes and these are at the top of the list right now. Feel free to reach out if you have any questions and/or concerns about fit.
Size Purchased: 42.5, I could wear a 42, but like the extra room.
For reference I wear a Specialized 42.5, Shimano 42.5, Giro 43, Adidas 42-¾, Nike 42.5, Sidi 42 / 42.5

I wear SIDI 42.5 , but was told to buy 42 due to that they do run larger and that the toe box was wider than the SIDI's , reason for which I ordered them. It turns out that size wise , they were right, but having a wider toe box, no way !!!! Dissapointed, because the shoe looks extremely nice, and construction wise, excellent.

so Mike I wear a Sidi 44,Pearl Izumi 44 and Specialized 44
with this specific shoe being a tad bit larger .....I was thinking a 43.5 !
Correct ?
Thanks ,
