Just bought these along with another similarly priced shoe to replace a couple of old warriors. Both shoes fit well, but it's not until I got to mile 30 and beyond that can I tell the difference. The Sidis are super comfortable and I don't even think about them on longer rides. Yeah, they're heavier, but that doesn't mean as much to me as long distance comfort. Sidi has found a new fan!

So why didn't I give them a 5 Star? Because the insert to too thin (my opinion). This is the case with most shoes -- so I purchase a gel insert at a local CVS. Very light. Great closure system. I'm a 8.5-9 shoe size and I have owned Sidi shoes before so I know my size, 43.

Based on this site’s sizing chart, I ordered the 43.5 since my Northwaves are 42. Size was dead on, though they were so comfortable I initially thought they must be too big. Nope. Just the most comfortable bike shoes I have ever owned. Closure adjustments really fine tune the comfort and fit. Even the heel width is adjustable!

And, having tried in the past to find replacement parts for other brands, I love SIDI’s easy replacement of worn or broken parts.

The shoes are light, comfortable, stiff soled, and even nice to look at. Combine that with Competitive Cyclist’s sale price and I am one happy guy.

I also like that CC called me to offer any sort of support I might want, even though I got the size right the first time and all went smoothly. They even offered to cover return shipping if I needed a different size. I mean who does that?!

I love Sidi for CX as well as Road. And the W-Push’s TECNO over the newer Vent’s. While Sidi’s are a bit heavier than some of the competition I find I can ride for hours in these without any discomfort. I am 6’2” & 190lbs and their “overbuilt” design is exactly what I need. The uppers conform to my feet better than the others and the heel cup adjustment seals the deal for me. I absolutely love these shoes and own more pairs than I am willing to admit.

Great Sidi shoes!

I just bought these to replace a pair of 12 year old shimano shoes. They were quite expensive. I really love the heel Security system. I have had trouble with heel lift with my previous shoes and I had to tighten them down a little too much. This lead to severe foot cramping on longer rides. I can dial in each shoe with a different level of security with these so I don't have to crank down the wires over my forefoot. So far this has helped out a lot. The build seems very solid and the carbon sole is stiff. I can put down the power without any flex in the sole. I have put these through the wringer on Zwift with a Wahoo Kickr.

just a bit confused and hoped the liner would be BLACK (as in the pic) so they wouldn't get that funky grey dirty color from the road...but it's white! anyway, i've used the WIRE since it's beginning and it is solid. tried the SHOT, buy didn't like the cluster of dials on top...felt odd and not comfy....so, back to the WIRE...and so many colors!! i just wish the one in the pic matched the one in hand....details....

Sidi wearer for over 15 years. I usually wear womens, but jumped over to mens because the styles were better. It took a few tries to get the right fit, but I am very happy. Been wearing the wire vents for 8 months now and about 5000miles. They are great shoes, comfortable and stiff. The right shoe does loosen a bit, but nothing I cant reach down and quickly tighten. CC are pros at what they do. Thanks, Doug for all the assistance.

These are truly well built shoes stocked full of amazing technical bits. The size length seems right on and also on the typical width -- unfortunately, I have B/C feet, despite the length, so I'll return them . At the cost, I should try a more narrow type/style/brand. At to Competitive Cyclist, these guys are as professional as it gets. THANKS!

This is my second pair. Fit is perfect. Very stiff sole for good power transfer and extremely comfortable on long rides.

I helped a customer nail down the shoe that would work best for him. This is what he had to say:

"WOW!! What an amazing shoe. To give you a little backround about myself, I am 6’1” and weigh 183lbs. I have been road cycling for the last 4 and a half years (about 2000-2500 miles per year). I got into road cycling as a triathlete, and now cycling is my passion. I’ve done many triathlons, including 4 Half ironman races, but my passion is definitely cycling. I’ve gone through about 1 pair of shoes a year and have never seemed to find “the one”. Upon opening the Sidi box, I almost immediately thought the price tag was worth it…..just based off of looks! They look like they are made extremely well and built to last. I put my normal cycling socks on and was super excited to slip my foot into my new cycling gear! My initial thought was I bought the wrong size. I felt like maybe I was a half size too big, however, with the amount of adjustments the shoe offers, I was able to get a nice snug fit. So the shoes are on and i’m ready to hop on the trainer and give my new Sidi's a go. I IMMEDIATELY felt the benefit of the super stiff carbon sole. I felt like my power was being transferred to my pedals more efficiently than ever before. I’ve been riding on the trainer (winters suck in the Northeast) since November (training for my first Gran Fondo in May). My FTP has been steadily increasing. I was at 242 FTP before my maiden voyage in the Sidi Wire’s. After my first ride, my FTP jumped to 258 and I’m up to 279 after my ride today. I’m AMAZED at the gains I’ve made over my last 2 rides! I’m almost in disbelief, considering I’ve made minimal gains over the entire winter so far. Its hard to imagine its simply from changing my shoes, but I feel a considerable difference in the power of my pedal stroke AND my legs aren't fatiguing as quickly! I am now a Sidi convert! As i’ve said before, I am a cyclist on a budget so these were an expensive purchase for me, but in my opinion, worth EVERY PENNY!! Thank you for recommending these shoes to me."

I tried shoes from Specialized, Gaerne, Gore and finally Sidi, all of them in multiple sizes. The Sidi was the only shoe that fit well. With all the other shoes my heal would lift up while riding.

The Sidi has a heel retention system that really works well and makes sure your foot and your heel will not come out. The closure system works very well and is very easy to use.

The quality of the shoes are also excellent and seem made to last. The shoes are not as light as some of the other shoes, but they are well built and I can tell that they wont be falling apart.

Love these shoes. They made them slightly wider in the toe box area from when I bought a pair of Genius 6.6 several years ago. At the time I had to get mega because Sidi ran narrow. I can say that this shoe runs true to size and width. Love the techno 3 boa's very easy for micro adjustments on the bike with the push button. I had a pair of Lakes I bought from CC a couple years ago and they were great. However I found that the thing I missed most about Sidi was the heel retention system. Love it, keeps the foot locked in place.

I will say that the Sidi's do weight more than my Lakes (CX237), but it is not a huge deal to me. Others might be turned off by the weight.

190cm (6'3"), 94kg (207#), ~15,000km/yr: I've probably put 80,000 km on three prior pair of Specialized S-Works that were my go to favorites. Unfortunately they changed the design so it was time to move on. These SIDI's looked to be the "one". I've tough feet to fit, wide forefoot, hammer toes, narrow heels. I got the 45.5 which is the same as the S-Works I've ridden for years, too tight. I exchanged them for 46's and these will I think do the trick. Length is still ok, width is good despite my wide forefoot. I didn't want to go with a "wide", though I do this is street shoes, as they tend to get sloppy with time in my experience. If you are considering these suggest you go up about a half size. Right out of the box they are very comfortable and the area around my big toe joint will stretch and mold once they get wet. I agree with a previous post about the closure, hard to improve on BOA but I don't think these will be too tough to get used to and unlike BOA's I don't expect them to loosen inside booties.

So this pair will be a keeper and I'll write a more detailed review in a couple of months after I've got a few thousand km on them.

This is a 1,500km update. It took about 1,000 km (~ 2 weeks, 30 hours of riding) to get these properly "broken in" to my "frankenfeet". They were pretty comfortable right out of the box but now they are "dancing shoes". I did a 200km ~6 hour solo ride in them on Saturday with no issues start to finish. They are stiff, great power transfer, and the closure system and adjustable heel cup really allow a perfect fit. I replaced the stock insoles with Superfeet Carbon insoles which cradle my feet better and offer better vibration absorption without losing road feel on these crap chip sealed roads I ride on most of the time.
Some have commented on the SIDI closure vs. the BOA's. BOA's are great but frankly there is nothing in the SIDI closure that is not to love in my opinion, operation is very similar to the BOA and yes, you have to press the red button to adjust them on the fly but this is a minor deal and offsets the fact that they will not loosen when using booties which I've found to be an issue with BOA's. Easy to get used to, both great systems, no drama either way in my view and I switch back and forth across the several pair of cycling shoes that I have. I do think though that for a road shoe I prefer the SIDI system.

I do a lot of hot weather riding, and the vent system on these seems to work as advertised, I find them to be well ventilated.

After break in I am very happy with these, highly tunable fit, all day comfortable, and great power transfer. Expensive, definitely but I expect based on past experience that SIDI quality will mean a long service life.

I'm not one to criticize publicly. OK, maybe I am when I feel there's a benefit to express alternate viewpoints. Therefore, if you want a hearts and flowers review, I'll do my best to keep to the facts after admitting Sidi shoes are beautiful, made in Italy, and no doubt durable. My problem with them is their "patented" closure system. It's one more step than necessary. Instead of improving upon the BOA closure, they complicated it by adding the additional step requiring you to unlock the handle before you can turn it. If you frequently adjust the tension, you'll appreciate the simplicity of the BOA closure. If it ain't broke, don't fix it. My other gripe is the comfort of the footbed of these Sidi's. Why not pay BOA their due share (considering the shoes retail for $400+) and instead take a page out of Lake's design book and improve the versatility of their soles to accommodate more shapes of feet. Who wouldn't pay a premium for glass slippers in cycling shoes? I put some time and money into trying all the very high end kicks available and none is close to the Lake CX 402's with their moldable carbon sole. I'm not in anyone's pocket just offering this up to people with high arches (and too often numb feet as a result of improperly supportive heals). For the record, I bought these Sidi's in neon green and loved the way they look but just never was comfortable over long rides. Most importantly, disregard everything I'm saying if you have low arches and think Sidi is the cat's meow. No doubt you'll get the nod from the weekend warriors sporting their Sidi's. However, if you want to distinguish yourself from the mob, look into a pair of custom kangaroos. Just my two cents.

I ride every day best fitting sidi shoes ever. I have 3 pairs of sidi and the wire push fits the best ,wide in the toe box , size 46 - 11.5

I have ridden every high end shoe imaginable, and all perform admirably well, but the Wire's are a cut above. The fit is such that your feet feel as one with the bike; no foot pain, no hot spots, no issues at all!

Not only are they the most supremely comfortable high-end shoes I have ever worn, they are every bit as stiff as the Shimano R-321 and Specialized S-Works shoes I have recently owned.

If you're looking for the best shoes money can buy without going custom, look no further!!

Oh, and get the green while they last; could you ask for a better colored shoe!?

Very disappointed in the performance and fit of such a beautiful pair of shoes especially after breaking them in (2k). They have stretched out at least half a size and the teeth on heel straps do not hold their position if you crank too hard on the wratcheting lace.

I struggle with shoe fit whether it's cycling or street shoe. It's always a problem for me. These shoes are amazing because you can get them to fit like a glove with the boa system that Sidi has created. Between the closure system and the heel adjustment, you should be able to make these shoes fit perfectly (provided you don't have mega wide feet). Because the boa system works so well, I find that I can tighten the shoes down less than with other systems but yet get a fit where there is (comfortably) zero movement of my foot in the shoe.

This last is, I think, slightly wider than Sidi's previous normal last. I wear a either a 10.5 or an 11 depending on the shoe, but for Sidi I wear a 44.5 and it fits perfectly even though Competitive Cyclist's chart says that would match up to a 10. In all the Sidi shoes I've worn before, the regular fit has been too narrow and I've gone to the Megas to get fit properly. In this shoe, that's not necessary. My normal width in shoes is regular to slightly wide (again depending on the shoe).

The uppers are not supposed to stretch, and I don't think they do, but they will conform to your feet. So when trying these on, put them on for an hour or so.

I like these so much, I have both the road and mtb version and find the fit to be equivalent between them.

I have about 5000 miles on these shoes. I have them mounted to Speedplay cleats and it all seems to work very well.

I tried these shoes on side by side with other high end models of competing brands and was REALLY surprised at the weight difference. I have only ridden Sidi and have two pair. They have been through the wringer for over 4 years now. So in terms of quality, they get 5 stars from me. But within a year, my road shoes stretched and the heel became very loose. I have dealt with blisters for a few seasons and am now ready for a change. I decided to try these out. For the price, I just couldn't get over the weight difference between these and other pro-level shoes! I ended up returning these because they ran too narrow in the forefoot and because of the weight.
