After a lot of research and reading countless reviews I am very happy with my purchase of the Fizik R5B road cycling shoes. They are extremely comfortable and easy to put on and adjust. The best road cycling shoes that I have owned.
This is my third pair of road shoes using the Boa system and these are the easiest and quickest to put on and adjust for a comfortable fit. The only thing that I would change about this shoe is the velcro strap at the toe. It could do without that velcro strap.
I have been a Sidi customer for over 30 years. I thought I would never buy anything but Sidi's as I have always had great fit, durability and comfort from them. Lately, however, I think their prices have gone up too high, especially the models with the wire closure system. Durability is TBD, but I consider this shoe, with an excellent wire closure system (that really works), to be a bargain. Nice wok Fizik!
