Fist I was a bit skeptical, I have ridden in Shimano shoes for many years but a friend convinced me to try this Fizik R5 after using it 3 times - first time on Rodillo in 1 hour to try, no major problems - then 2 more times on the road (4+5 hours) - I confirm this is a good shoe, looks cool and is the perfect second shoe for my size) I ordered 43 (my normal size is 42) and it's a size up - think 42.5 would be perfect - hence only 4 stars because even after some resizing it's a bit tight
