tonyawrote a review of Fi'zi:k M5B Donna Boa Shoe - Women's on February 27, 2016
Familiarity: I've used it several times
These shoes are sexy and fit well, but are not compatible with SPD. I unfortunately only wore mine a few times (probably 15 hours total), and had to stop due to knee discomfort caused by the poor interface with Shimano pedals. Sadly!
When walking the cleat stood out of the treads, so the shoes were really uncomfortable to walk in as well.
