Overall these are a pretty good mountain bike shoe. Comfortable for hours of wear, with wonderful stiffness for excellent power transfer and reduction of fatigue on grueling rides. Breathability is decent, but not stellar. Sole grip is solid. The one downside is that they run about a half-size larger than normal for Sidis.
I really like the fit of these shoes. I did replace the OEM sock liner with a molded insole and that works much better with my 60 year-old feet. Other than that, a great fit. I think, however, the BOA flip-up tabs could be better replaced with simple pop-up dials like other brands. The lower BOA adjustment gets in the way of my toe caps this spring, so less off the foot ends up covered. Haven't ridden anything north of 80km here in the Northeast US this season. It's been a bit too brisk and windy and rainy to confidently get out on a nice day. Soon...
Was looking for a shoe for indoor winter cycling and SiDi has always been my brand. I normally wear their Mega (wide) size, but the prices for something that I'm only using for winter training was out of reach. These are not "Mega's" so I took one size larger and they work just fine. Catching an end-of-year sale really helped my frugal experiment.
They are quite stiff, consistent with my expectations for Sidi's.
Sorry I can't rate their 'road worthiness' but wanted to provide something.
Sidi Genius has been around for a while now with this being version 10.
Shoes, like saddles, can be a very personal thing. I have had several iterations of this shoe and they have never disappointed. The quality and durability of the product have always been there for me. Also, the replaceable heal and straps is great. I have replaced both on several pairs and that helps keep the overall lifetime cost down since the uppers and soles are close to bulletproof.
