Light as air.

The Shimano Wire Shoes take the best of the Ergo3 and go even lighter and stiffer for more power to the pedals.

You'd almost think that if cycling shoes keep getting lighter, riders will soon be donning carbon-molded socks with integrated cleats. Yet Sidi keeps doing the impossible and decreasing weight while simultaneously improving fit. The Sidi Wire Shoes take the best of its predecessor, the Ergo 3, and create a stiff-soled, race-ready shoe that gives you the perfect fit every time, even if adjusted on-the-fly, from the saddle.

To begin with, unlike the three separate buckles used in the Ergo 3, Sidi used the Tecno 3 buckle to secure the Wire. This system uses a single wheel with a continuous wire running through to the forefoot and a separate to secure the strap at the instep. The buckles are released with a pinch to unwind the wire and are easily tightened by opening the switch and turning the buckle. This system is wired with a low-friction line which keeps the buckles turning smoothly. Because the Tecno 3 system features micro-adjustability, you're able to adjust the Wire to the perfect fit. The tongue and instep strap have been given extra padding for comfort and protection from tight buckles.

Sidi used it's hand-laid vented carbon sole for stiffness and maximum power transfer. And while it's built using the same method as Sidi's Carbon Lite Sole, it is actually 38grams lighter. The forefoot of the sole features a vent inlet which pushes air beneath the sole to cool your feet. Unlike many other shoes that tout the same sort of venting, on the Sidi Wire Shoes, you're able to close the vents to keep chilly breezes out-it is even possible to do it while riding. And on those hot days, the vents work in conjunction with Lorica and mesh uppers to keep your feet dry and comfortable.

As far as fit is concerned, Sidi's Heel Security System (HSS) keeps your foot from slipping inside of the shoe. It is a composite band that tightens the shoe around your achilles heel to prevent your foot from pulling out of the shoe. It is adjustable using a small Allen key. By keeping your shoes as tightly fitted to your feet as possible, minimal power is lost and the more power that is transferred directly to the drivetrain of the bike.

The Sidi Wire Shoes are available in the colors Red/white vernice, Vernice white, and Black vernice. They come in whole and half sizes from 39.0 to 46.5 and in whole sizes 47.0 and 48.0.

Another amazing pair of Sidi's

Fit perfectly, and transfer power directly to the pedals.

must have

  • Familiarity: I've used it several times

I got those on 6 months ago. Those are very made well , high quality , easy to wash. Lightweight . Basically on hot summer my feet always stay dry.
I was amazed on how great and powerful these are. POWER transfer is just insane. Srint or climb is just beautiful .Highly recomm. for those. Worth every single penny. Fit is just perfect , you feet " click " with those. Magical shoes.

Size. I used to own Genius II , and size 46.5 was perfect. I got Wire in 46,5 as well , and I had to exchanged for 47. My feet is wide so I think that was a reason. I got white color . Very minimalistic look and beautiful.

Great quality shoe!

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

More form fitting than the Genius 6.6. Love the Techno 3 system. Much more effetive at achieving the desired tightness. Sizing in terms of length runs similar to the Genius 6.6 Vent, other than the width. Really good looking shoe and way lighter than any other Sidi I have owned.

Perfect Shoe for me

  • Familiarity: I've put it through the wringer

The Sidi Wire is the perfect shoe for me. I started this year with the Sidi Genius Fit 5. Nice shoe but the fit began to be a problem as we entered the warmer months of summer. With thinner socks and possibly a bit of stretching in the uppers, I could not get a snug fit that was also comfortable. Hot spots on the instep developed. It was time for another shoe. I went with a 42 for the Wire. I was a 42.5 in the Genius Fit 5. I'm 5'7" and 140lbs.

The Wire fits snug and comfortable. There is a great range of precise control of how snug the shoe is with the wire buckles. Adjusting them mid-ride is quick and easy. The soles are stiff as expected, they are carbon. The adjustment on the heels is very nice as well. I have narrow heels and tightening them just a bit keep my heels in place all the time. I can't say much for the supplied insoles because I always pull them out of any shoe I own and throw in a pair of Superfeet. The Superfeet Carbon insoles are thin enough to not affect the fit of the shoes but they provide the necessary support to keep my feet happy all day long. The vented soles really do work. Cool and dry feet are great. After a long hard day in the saddle my feet don't suffer any hot spots or soreness.

Not worth the money

  • Familiarity: I've put it through the wringer

I could not be more disappointed with this over priced, over marketed cycling shoe. Although it is well made, it is not comfortable. The shoe in no way conforms to my foot. In addition, the location of the strap is too high on the shoe such that when I snug it down it creates a painful hot spot on my inner ankle bone. In addition, I have to re-tighten or readjust the wire 'ratchet' system at least 3 or 4 times on every ride. It's annoying. I've retired these shoes after only 3 months. A much better shoe option would be the top of the line Shimano R-series or Specialized S-works. Those shoes fit like a glove. I am a former national and WC who just wants to say, in my opinion, these shoes are definitely not worth the money!

The best

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I have ridden SIDI shoes over the last 15 years. I decided long ago to not use any thing else. Wires top anything SIDI has put out making them the best shoe period in my opinion. They have great arch support, extremely comfortable on 3hour plus rides and the venting is makes a huge difference in keeping my socks drier and feet cooler. Maybe this is not as big a deal on shorter rides but on long ones, it really matters.

Been looking at these shoes for a...

Been looking at these shoes for a while. I currently have a specialized triathlon shoe size 43 (US 9). Anyone in the same size and what size wire did you purchase. I'm hesitant to buy them because I'm not positive on my size and no shop close to me sells them. Any help would really be appreciated.

These shoes run very true to size. They are a bit narrow, though. Good luck!

They run very small. I've worn a Sidi in a 46 for over a decade in 5 or 6 different models and this is almost a full size smaller as best as I can tell. Purchased them and returned them.

My Wires are a half-size up from my old Specialized shoes (46 Sidi = 45.5 Specialized). The Wires are much more comfortable, I can't see myself buying anything other than Sidi from now on.

Different fit than Ergo 3

  • Familiarity: I returned this product before using it

I have been riding Sidi road and MTB shoes for decades. They are top-notch in technology, design and construction. My last pair of Ergo 3's are still in use but I was intrigued with the Sidi Wire model so I ordered a pair and was disappointed because I found that the fit had definitely changed, not necessarily for the worse, as you can read from the other comments, but in a way that, for my foot, was a problem. I have a flat low-arch foot. It seemed that the cut of the edge of the upper, where it passes under the outside ankle bone and from there forward was significantly higher and closer to the bone. This did not work for me so I returned them to CC. FWIW, I continue to be impressed at CC's level of service, which is excellent.

Best Road Shoe On The Market

  • Familiarity: I've used it several times

The Sidi Wire is hands down the most comfortable road shoe I have ever ridden. You are able to adjust it perfectly with the techno 3 buckles. You can also adjust the heel cup so your foot doesn't move at all. The size chart is spot on. I wear a 10.5 and the 45 fits me perfectly with my toes just touching in the end. These shoes will break in a bit so if you are in between sizes, I would size down and let the shoe break in.

The sole of the shoe is very stiff and provides great power transfer. These shoes are so light that they feel like my feet are going to float away. When you are pedaling it feels like there is nothing on your feet. For this price, these shoes do just about everything you could ask of them... except make you coffee in the morning. If you have any questions about these shoes please give me a call.

Here is my contact information: My direct line 801.736.6396 ex. 4389. Feel free call to me anytime, I?m always happy to talk about bikes or gear or the weather. Whatever works! I?m here Mon, Tues and Friday 1:30-10pm MST and Saturday 9-5:30 as well as Sunday 10-7. I look forward to speaking with you.

Nate, please buy my Sidi Wire shoes. They are size 45. I hate them.

bmcp -- You have to realize that everyone's feet fit differently and some brands fit some people better while other brands fit other people better. It is not a criticism of Sidi if their shoes do not fit you. Sidi fits a great many people perfectly, and that is why they are so popular.

Excellent :)

  • Familiarity: I've put it through the wringer

Have ridden Sidi's for 15 years now - and tried each model - last ones were the Ergo 3's. First, they are super light, vs my Ergo 3's, they are 98gms lighter for the pair - that is substantial. Second, they are noticeably more vented - there is a new vent in the tongue which improves air circulation, and it's evident. Additionally, there just seems to be more room in the toe box - can't explain it, but with the shoe nice and tight - still some nice room for the toes :) Best Sidi shoe yet - and Competitive always has an awesome price :)

Excellent road shoes!

I was looking to replace an old pair of Shimanos and spent a lot of time researching a number of different shoes before I came across Sidi. A lot of the other brands I tried did not have "the fit" I was looking for, but this shoe did. I know sizing among brands can be very confusing since a size in one brand may actually be smaller or larger in another for the exact same size!

For reference, I normally wear a 9.5-10 in athletic shoes (43.5-44 in Euro). I have a moderate to low arch. The width of my foot is around the E size; the Sidi website says their regular width shoe will fit a C-E foot width range. I purchased the Wire in a Euro 44 size (US 10, 27cm), regular width. These shoes fit like a glove. A snug fit, almost like slippers, but not tight in any areas in the top, front or sides of my feet. I have enough room to wiggle my toes in the toe box and about 3-4 mm of space from my big toe to the end of the shoe, with no back and forth movement of my foot once in the shoe. The heel cup does a nice job of keeping my heel in place. There is minimal slip even with thin cycling socks and not having the Heel Security System screws tightened up. The comfort step insoles are a big improvement from the insoles on other Sidi models like the Genius 6.6 and Ergo 3 (which I tried on in stores), it provides more padding and better arch support while not being too bulky inside the shoe, very comfortable. The Tecno 3 closure system is great and easy to use. It provides even pressure across all areas of my foot and can be easily adjusted when things get too tight on a ride. I believe it is superior to the buckle and Velcro offerings on other Sidi shoes.
The construction of these shoes is top notch and the pictures online cannot do justice to how nice these shoes look in person. While on the expensive side, I'd say don't even think about the price because these shoes are worth every penny. With most parts being replaceable on these Sidi's, they should last 5+ years.
