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.
