I have always been a fan of Sidi shoes. I was looking for a replacement for a 15-year-old pair that I have been using indoors on my trainer, and these were an obvious pick because ventilation is important. As noted in another review, the fit is narrow, but this was only a minor inconvenience while slipping into the shoe - after the dials are tightened the body of the shoe conforms to fit my foot well. Definitely meets my needs.
Fantastic, especially on a hot day! Great ventilation and very stiff. Runs narrow though.
