If you're looking to invest in a road shoe that will see you through seasons of training while weathering fickle trends, pause your search and take a look at the Fizik R4B Uomo Boa Shoes. Known for its clean lines and too-cool minimal saddle silhouettes, Fizik brings the same classic style to its entire line of shoes. More accessible to the self-sponsored cyclist than the R1B or R3B, the R4B Uomo echoes the same sleek design and effective construction as its pricier siblings, with a carbon composite sole and ample range to fine-tune fit.
Fizik actually uses Microtex uppers across its entire line, so your toes will be wiggling around underneath the same perforated synthetic leather uppers as the pros wearing the R1B. Flexible and light, the material is stronger than it looks. Trust it to weather road grit and unexpected showers with grace as you use the BOA dial and two hook-and-loop straps to secure it around the contours of your foot for a slip-free fit. Underneath the shoe, a carbon-injected synthetic outsole blends some of the rigidity of carbon with the durability of nylon for reliable power transfer. Within the shoe, Fizik includes its Cycling Insole, molded to provide support to your hardworking foot as you turn the pedals alongside the expertly shaped heel cup.

- Q & A
Comfortable yet stiff enough shoe
- Familiarity: I've used it once or twice and have initial impressions
- Fit: True to size
Most comfortable of the Fizik line that I tried (R1 & R3) The R4 has a wider toe box it seems and the asymmetric upper reduces pressure on the top of my foot. Wore specialized for years but am now firmly a Fizik fan.
What is the "injected carbon composite" outsole? Is there a stiffness index to compare with the carbon R3B?
