I have ridden Sidi shoes for over a decade, as they comfortable and hold up great year after year. Although the wearable parts are replaceable, the only thing I have ever had to replace is the heel pad.
I wanted to move on from Velcro and the clunky (but durable) ratcheting buckle to a more modern Boa-like mechanism, so I upgraded from a 3 year-old pair of Genius 7 shoes to these. The Genius 10 shoe looks much better, and fits better than the Genius 7. The Sidi Tecno-3 mechanism works very well to get a secure, and evenly snug fit across the whole foot. However, like another reviewer noted above, I think that the Genius 10 shoe is just a bit longer than the Genius 7. In the Genius 7 a size 45.5 fit me perfectly, but a 45.5 in the Genius 10 was just a few millimeters too long, so I returned them for a size 45 - which is perfect. The Genius 10 is also plenty wide in the standard D width for me. Overall, these are great shoes for the cycling enthusiast, comparable to $400 shoes in other competitive brands.
So what is in it for $300? First thing that caught my attention? The feel. It fits too good. Ive been used to a shoe, and a very good shoe, but a lesser shoe. It fits so good it made me second guess it. I adjusted the boas repeatedly. I tried it on with a wool sock. I tried it on with no sock. I think we get so used to the things we use everyday. That makes change hard. But not impossible. Its not narrow. I have plenty, not too much room at the toe. It feels like a slipper. It looks small too. The same size shoe(43) in my current road shoe are a bit bigger. The boas adjust precisely. Pinch and release, crank them to snug it down. There isnt any information as to size recommended on this site. I dont think I found it exactly on Sidis sight either. 43 read 8.8 on the box. They are Italian so take it for what its worth. I installed my Speedplay cleats and did a few laps to get them positioned just right. Bottom line. Probably worth more than $300.
Right out of the box, these are great looking shoes. After a couple hundred miles and some adjustments to the cleats, they feel great. I'd like to give them 5 stars but I need to use them for a longer period of time before I can do that. They seem like a durable shoe and I hope they last me for a number of years.
I'm very easy going and really enjoy a great product. Was a little nervous about the price. Had been watching the shoes for awhile. They went on sale thought I would give them a try. I have no complaints and very happy with the fit, feel and comfort. Had them a little over 4 months. Ride around 100 miles a week. I would recommend the shoe and buy them again when needed.
So I've wore sidi shoes for 25 years and have only had 3 pairs,this being my fourth.I bought a 44 and it was tight on the top of my toes and in the top of my foot where you tighten the dial....it took 3 weeks and a nice specialized inner sole to mold these to my foot,they are super comfy now....the only downside is the tecno 3 dials they are hard to do on the fly all the models above these have a push button inner that is much more user friendly ..I most likely will up gragde those and swap them out
I've been a happy Sidi wearer for 30 years, and recently upgraded from a scuffed but still excellent pair of Genius 5's to the Genius 10. I've tried other shoes, and they either are too rigid in the upper or too flexible on the sole. Sidi manages to get it right for me, with a supple, easy fitting upper and a fantastically rigid, power transmitting sole.
I especially like the updated dial closure adjusters. Unlike the 5's velcro and lever combination, this manages to be easy to adjust, open, and close, better fitting, and genuinely adjustable on the fly - really! I've pretty easily both loosened and tightened the closures while riding, which is a very nice thing to be able to do.
While I was tempted to splurge on the top of the line shoe, I just couldn't justify the extra cost for what was likely to be an imperceptible (at least to me) improvement.
The only thing I would alert folks to is that it appears Sidi had changed the shoe last from the Genius 5, as these 47's are slightly longer than the 47's they replace. Not a deal breaker, but if I had been trying them on in person I might have ended up with 46.5. These still fit fine on my 11.5-12 sized feet.
All in all, a superb shoe.
I upgraded from my old Sidi Genius 5 shoes to these. My impressions (1) The styling of the shoe is a major upgrade. These look great! (2) Genius 5 shoes fit me well. Genius 10 fit me better. With the Techno-3 adjusters, you can get a perfect fit. Supremely comfortable! In my experience, these are more comfortable than my much-more-expensive fizik R1 Infinito shoes or the much-more-expensive Sidi Wire 2. (Yes, I prefer them to the Sidi Wire 2, even if they were the same price. I sent the Wire 2 back.) I'm glad I made this purchase!
But . . . I'm not a big fan of the Techno-3 adjuster mechanism. Sitting still, on a chair, they are fine. But when on the bike, it is almost impossible to find the lever, pop it up, and adjust the tension. The 2-way BOA dials are much, much easier to adjust on the bike. A Sidi Genius 10 shoe with 2-way BOA dials, if it existed, could be the perfect shoe.
