Genius 10 is everything you expect in a pro-level road shoe: Millennium 5 Carbon Composite Sole, Caliper Buckle two-way ratchet closure and many more. High quality carbon fiber reinforced nylon sole in carbon look. The addition of carbon results in excellent strength with optimum comfort in the entire foot area. It has a non-slip, replaceable polyurethane heel for comfortable walking. With alignment scale for optimal positioning of the pedal plates. SIDI's TECHNO-3 SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. SIDI's famously reliable and replaceable closures are improved by an all new proprietary SIDI Wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most SIDI small parts, the TECNO-3 BUCKLE is serviceable and replaceable. Incorporates features of resistance, stability, lightness, transpirability, water-repellency and eco-friendliness. It is manufactured using the "Water-Tech" water treatment. Lower environmental impact, less noxious emissions into the air and into the work environment and the fact that not solvents, but water-based products were used, is beneficial to the environment as well as the final user.

Size guide said they were 25.5cm when they arrived they were tiny and measured 24cm. So didn’t bother trying to find the right size if they can’t even print an accurate guide online.

Having very narrow feet I often struggle to find a shoe that fits. These Sidis are perfect for me. Obviously, that means that others may find them tight and might need to size upI'm also a fan of the ratchet system which I prefer to the Boa system I have on other shoes.The soles are stiff but comfortable and I haven't experienced any hot spots so far. Build quality is top not too..Excellent value at this price point , throughly recommend.Brilliant service and delivery from Sigma too

Until now I've used mtb shoe set up and have changed to these which were twice the price so I had high hopes all the reviews were 5 stars and pretty much all said the shoes were true to size so thought I'd try these as I was buying online which we all know can be problematic and I agree with all the previous reviews and won't look back on this purchase. The fit for me is exceptional with added arch supports and just all round comfort style and material is of a good quality, I hasten to add I got these shoes at a reduced price, which would be something we could all appreciate. It says would I recommend this product, wholeheartedly is the answer.
These are great shoes, nice stiff soles and feel really sturdy.They weren’t particularly comfortable out of the box due to some seams and stitching around the inside of the toe box but feel much better after a couple of rides.I’d originally bought the SIDI Prima in my correct size but they were too small so sent them back in favour of the Genius in a larger size so bear that in mind.They were expensive but all of the adjustable parts are replaceable so I’m confident that they will last a fair few seasons.
When I first open the box the optic of the shoe were underwhelmed. But as I inspect the shoe and try it on n walk around, the shoe start to grow on me. The design is simple versus the old genius I bought 10 yrs ago. It is lighter and with Mega fit it feels great on my toe box and instep. The BOA like fastener were fun to play with n gives a different look. Went for a test ride n it felt great n deliver pedal power directly. I recommend 1 size up.
Great shoes and very comfortable.Bought a white pair for spring/summer and even bought a black pair for autumn/winter riding.I did find the size 44 a bit bigger than my previous size 44 but it’s not a deal breaker.Might just insert some inner soles to make it a more snug fit.
My first foray in to Sidi shoes - impressed. The shoes really are things of beauty and ooze quality. Having had Italian shoes before I was concerned about sizing. I followed the Sidi guide and sought advice from Sigma - who said do as Sidi suggest with the measuring guide. Bingo, spot on...true to size. Highly recommended
Had these shoes for about a month now and so far they've proven to be a good choice. My normal shoe size is UK 9.5 and Sidi 44 fit perfectly. The dial closure system takes a little getting used to but it's easy to tighten and loosen to get the optimum fit. The composite sole is pretty stiff and I didn't notice any flex when putting the power down (I'm 70kgs/ 178cms). I'm finding the shoes comfortable but they might not suit someone who has wide feet. The uppers are easy to clean and the shoes dry reasonably quickly after a downpour.
These Sidi shoes have fit very well right out of the box. I have 2 hotspots that aren't bad and if they go away like I think they will, they will be a 5 star shoe in my opinion. The service and shipping was spot on and one more reason I keep using Competitive Cycling. Thank you.
