Trevor L.wrote a review of Fi'zi:k R4B Uomo Boa Cycling Shoe on April 25, 2016
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.
