Paul S.wrote a review of Fi'zi:k R4B Uomo Boa Cycling Shoe on February 8, 2018
Familiarity: I've used it several times
Fit: Runs large
Coming from R5B, these are more stiff, they do seem to run larger then the R5B, I use a 45 in the R5 and a 44.5 in the R4B. I really have no complaints except these are made in China, unlike every other Fizik item I have, that are made in Italy, just never saw them doing something like this, but they appear to be very well made and look fantastic! Super comfy!!
