This was my first pair of Sidi shoes. They are by far the most comfortable mtb shoes that I've ever owned. Whether I'm climbing, descending, or riding on the rock and mud beaches along the Rio Grande, Sidis remain comfortable even when I stop for limited walking or standing still.
It took 2 tries to find the right size but backcountry.com / Competitive Cyclist were great to deal with when making the exchange.
I have a feeling that these shoes will last much longer than my Bontragers did.
