Lisa J.wrote a review of Fi'zi:k R4B Donna Boa Cycling Shoe - Women's on July 26, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
I upgraded to this shoe from my first shoes, Specialized Ember. As for size, I recommend measuring by MM not by US size. My street shoe size is 8 1/2 and I purchased a US 7 1/2 (according to this sizing chart) because I based the size off the millimeter measurement which means I purchased a US 9. It fits perfect. The tongue fits a little higher as another review comments, but I don't think this will pose a problem. Also like other reviewers, I had problems with my Shimano cleats. Using shims didn't work successfully, so I changed to the Look Keo pedal and found that the cleat fits to the contour of the sole perfectly without any augmentations, which was my preference and the Look and Shimano pedal have the same performance.
