Sidi recommends following the procedure below to ensure that you choose the right size.
Measure your foot by following these steps:
1. Put a sheet of paper on the floow with the short side against the wall.
2. Put the sole of your bare foot on it with the heel pressing against the wall.
3. Mark the point in front of the tip of your longest toe on the sheet of paper.
4. Measure the distance between the margin of the sheet of paper where you placed your heel and the point where you made the mark. Always round up the measurement to the nearest mm.
You may find that your right and left foot are different lengths. Always measure both of them and use the longest measurement as your reference.
If you are undecided between two sizes after consulting the table, Sidi recommends that you opt for the larger size.

A good shoe for a non-elite cyclist

I've used it several times
True to size
Size Bought
6` 0"
160 lbs

I've got a few hundred miles on these shoes. Fit is true to size, and plenty of toe/forefoot room, which is exactly what I was looking for to replace some custom-made road shoes that I eventually 'grew out of'. I like the retention system (Boa-like, but not true Boa as described on the webpage), the softness of the uppers, the overall looks. There's one down-side if you're looking for a really stiff sole: the sole is carbon-injected, not a true full carbon sole. If you're a sprinter and really put power to the pedals, this may be a drawback. But if you're a fast recreational cyclists who doesn't really sprint, I doubt you'll find the sole to be an issue. I sure don't. Giving 4 stars because of the sole issue, otherwise for me personally, it gets at least 4.5 stars. This shoe is a good value. I recommend it.

Terrific Shoe

I've used it several times
True to size
Size Bought

To be very fair, I wavered between 4 and 5 stars, but ultimately I’m comfortable with a 5 star rating on the Genius 10. I’ll get the only real negative in my mind out of the way up front - for the price I would expect a full carbon sole, and this is carbon composite. That said, I am not a pro peloton rider, and honestly do not know if I would be able to tell the difference as the soles are still extremely stiff and I didn’t feel flex even when doing a fitness test generating 1,000+ watts. The fit is very similar to any other Sidi model, but there is slightly more room in the toe box than the Genius 7, which I also own. This, for me, was welcome although the length is identical. Sidi shoes are also famous for their ability to have parts swapped out, so you can affordably keep you shoes in operation for a long time with an inexpensive new heel pad or by replacing (or upgrading) the Tecno Dials. Which does bring me to a relatively important point to call out...which is that the CC/Backcountry product description is actually pretty misleading. The CC description references Boa dials multiple times - THESE ARE NOT BOA DIALS. These are Sidi’s proprietary Tecno dials, which they invented before Boas existed. Which also means that Sidi did not ‘step into’ the boa game with these shoes, although this is the first Genius shoe to employ the dial closure. In total, these are far from the first shoes in Sidi’s lineup to leverage the Tecno dial. They are a very different operation than Boa dials, so if you’re accustomed to that system it may take some getting used to, but they are very accurate and I’ve found them easy to adjust on the fly. Are they as easy to adjust as Boa? No. They are, however, still easy to adjust and the are dramatically easier to service than Boa dials should anything go wrong. Overall I’ve found the Tecno dial system to be a huge upgrade to the HSV system on the Genius 7 - I have much better volume adjustment capabilities in the forefoot, and the closure holds much steadier than the velcro. The comfort is also very good, and I’ve been able to do 50+ miles without any numbness or hot spots. Although I’ve put a couple hundred miles in them already I fully expect shoes to last for thousands, so I don’t want to consider this a “through the wringer” type of review.

Good quality stiff shoe

I've used it several times
True to size
Size Bought
5` 3"
142 lbs

I'm biased because I like everything Sidi so my opinion is: They fit like every other Sidi shoe I own so if you wear a 42.5 in one shoe you'll wear a 42.5 in this one. I also own a pair of Dominator 10's and they appear to be the same except the Dominator has a mountain shoe tread and two hole cleat mounting. I've got about 25 hours on them now and the Boa's work as intended but it's easy to get them too tight. I marked the lace as it enters the boa to be consistent on tension. As the shoe has broken in the tongues feel better, they were stiff to start but are forming to my feet. I have very flat feet and while the insole is made for someone that has more of an arch, it feels fine to me. The sole is stiff but not like rocks. I like the low narrow heel, it keeps my heel secure and doesn't dig into my foot so it's been very comfortable. As opposed to another review, I don't expect shoes to stay clean. In fact I purposely get them wet and dirty while breaking them in so they form to my feet better and I don't look like newb. I have the yellow ones as well and they are certainly bright enough even dirty. TLDR: It's a good quality shoe and what I've come to expect from every Sidi shoe I've owned.

Very useful review. I have very flat, low volume feet and really appreciate the detail and perspective.

Smudge easy and impossible to clean

I've used it once or twice and have initial impressions

Hello, I just bought a pair of neon yellow Sidi Genius 10 shoes and notice they are getting ugly really fast. I'm talking about the toe area that all cyclists use to flip up the pedal to clip in. Because of the matte finish of the shoe and rough texture, they are picking up and soaking in every bit of black grease found on my relatively clean pedals. I've tried several things to try and get the stains out, but nothing works. I've worn them twice and can just picture how hideous they will be by next fall. What do you suggest?


Don't buy yellow shoes.

I have used yellow shoes for team training & racing; Mavics/Adidas, Sidi's. The newer harder shell yellow Mavics clean up but lacked comfort of a Sidi. The default cleaner for the Sidi's is Simple Green slighty diluted. It's true; all of the yellows will show scuffs/stains and that goes with the flash.

Use Speedplays; no flipping required. Plus, you get the benefit of a superior pedal system! Come to think of it, though, even in my Look days, I don’t recall having problems with smudging due to pedal use. Maybe it’s entry/exit technique?

Yellow is a safe color for some dusk rides. Agree with other commenter, swithch to speed play peddles should not have this problem, ive had mine for 6 plus years still feel and look great...

Mr. Clean Magic Eraser. Really. Magic.

Speedplay. I gave up flipping up my pedals last century. Been using Speedplays since '99. On my fourth pair of Sidi's between my road and mountain bike. Consistent fit. Stiff.
