The Pinnacle of design.

The Sidi Wire Speedplay's are the best of the best from the most popular cycling shoe manufacturer in the world

Sidi has parlayed its Ergo 3s as the creme de la creme of fine Italian design for years. They have been so popular that only subtle changes have been made over the years. But now, Sidi has trumped itself with the Wire Speedplays-a shoe with comfort, design, and weight that surpass even the Ergo 3.

The Wire isn't a completely new shoe. With the Ergo 3 already dominating, Sidi chose to use the same fit and comfort of the favorite with new added features. The most noticeable difference is that while the Ergo 3 was secured using three closures, two round buckles and one hook and loop, the Wire used the new Techno 3 buckle. This innovative design features a single point of closure for the forefoot and a second buckle at the ankle. The adjustments of each of the shoe's instep and forefoot buckles was designed to be more intuitive while on the bike. You pinch both buttons on either side of the buckle to lengthen the wire, or you toggle each button for extremely precise incremental adjustment. To tighten you just open and wind the buckle. The low-friction line keeps the buckle turning smoothly. The best part of the Techno 3 system is that it allows for more extensive adjustability and a more consistent fit across the shoe. To complement the buckle system, Sidi has added extra padding to the tongue and instep strap for those riders who prefer to crank down the buckles.

The sole used on the Wire features the same construction as the one used on the Ergo 3. The Vent Carbon sole, however, is 38grams lighter while retaining all of the stiffness that you've come to expect from Sidi. A rigid sole allows more efficient power transfer from your pedals to the drivetrain so that no watts are wasted. The vent inlet is in the toe and may be opened or closed to suit your personal preferences. When open, the air moves through the insole to cool your feet. And while the soles are stiff, a degree of flex was engineered into them so that you won't get hot spots.

Sidi also included its Heel Security System (HSS) which keeps your heel firmly within the shoe via a small Allen key adjustment. This rigid band, located on the exterior of the shoes, anchors over your achilles tendon so that your heel doesn't slip out when you are mashing the pedals. It also means that you won't need to tighten the buckles quite as tight to keep your feet in place, and this reduces chafing.

Finishing off the shoes are Lorica and microfiber uppers. Lorica, a synthetic leather, resists stretch and remains pliable even after getting wet. The mesh inserts help to further ventilate heat to keep your feet comfortable.

The Sidi Wire Speedplay Shoes are available in the color Vernice White and in odd and even sizes from 39.0 to 48.0. Please note that these shoes are designed for use with the Speedplay cleat system and come supplied with the Speedplay cleat protectors. We also offer the Wire shoes in 3-hole cleat compatibility.

Best shoe ever and worth the price

  • Familiarity: I've put it through the wringer

I am a Sidi fanboy. I've tried other shoes, and always go back to Sidi. I got a great deal on a set of DMT Prism Speedplay shoes, and was totally disappointed with the fit. I ponied up the money for the Wires and am in love. My previous Sidi shoes didn't really need replacing but were over ten years old and I wanted a Speedplay specific sole. The Wires feel like slippers and are the most comfortable road shoe I have ever worn. I do wish there were more color options with the Speedplay sole, but the white is very visible on the road, and the Vernice material easily wipes clean.

Some key installation items...

  • Familiarity: I've used it several times

Some key items to watch for:
1) The Sidi manual say to torque the 4 mounting screws (per shoe) to 4-5 N-m but the Speedplay manual says it should be 2.3 N-m. A quick call to Speedplay confirmed that 2.3 N-m is the correct torque.
2) The mounting screws that come with the cleats are 4x11mm. But these are too short to give a safe mount (per the Speedplay technical support rep). The proper screws should be 4x13mm. The Speedplay rep shipped me a set of 4x13mm mounting screws right away and for free.
3) Great customer support from Speedplay!

Slick Shoes

Perhaps the most PRO looking shoes out there... That and they are STIFF, the "Flex" Sidi talks about in their write up is not noticeable, but then again I'm coming from the Sidi composite sole. The 4-hole drilling makes mounting new cleats super easy, and adjusting them even easier! Be warned they do take some breaking in as they are completely Vernice and are rather rigid to start with. I've put 700miles on them since the new year and they are just now starting to feel molded to my feet. Expensive but perhaps the last shoe I'll ever buy.

Error in above list of features

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

The Sidi Wire Speedplay shoes (4 hole cleat) do NOT have the vented carbon fiber sole. Maybe the three hole cleat shoes have this feature. I still love these shoes, vented or not.

The outlet shoe shows only the 4 hole cleat...

The outlet shoe shows only the 4 hole cleat system on the bottom. Are there size 42 in the outlet shoe with a 3 hole cleat pattern?

Responded on

They are both the 4 hole Speedplay pattern. The difference between the outlet colorway and the other one is the season, otherwise they are they same shoe.

carbon sole protector plate

In case you were wondering, the Sidi Wire does come with the "carbon sole protector kit"that is required per Speedplay install instructions. This is a thin piece of sheet metal that fits between the Speedplay cleat and the shoe to prevent damage to the carbon sole. Be sure to keep it lubed!

yep, worth it!

  • Familiarity: I've used it several times
  • Fit: True to size

The Sidi Wire shoe is amazing. I was impressed from the first time that I tried them on, and I continue to be impressed every day. As with all Sidi products, the fit/finish is second to none. They are as comfortable and functional as they are beautiful.

As with all shoes, these may not be right for you. Every foot is different, and we all have different needs. Sidi tends to run a little narrow, and tends to have a tighter toe box, but they have made some wonderful adjustments to these shoes. The Wire is special in that it can offer more of a custom fit and therefore more comfort. The closure system is brilliant and can be rapidly adjusted on the bike. Even more important, the ratchet system holds, even over the longest, hardest ride.

Overall, the best shoe out there (especially for speedplay specific soles). I love these things and I look forward to years of comfortable and powerful riding. Thank you Sidi!

i have the sidi Ergo 3 size 46 but it could...

i have the sidi Ergo 3 size 46 but it could be a bit wider it fits perefect all else but my toes go a bit numb after riding is 46.5 wider or will Sidi be bringing out a Mega Fit for larger feat

Best Answer Responded on

The half size up will be a little wider, but you will have to try them on to see if it makes enough of a difference for your feet. With regards to the "Mega" option you mentioned, the Wire is currently only offered in standard sizes. No indication of a "Mega" Wire any time soon.
As you may have discovered, Sidi tends to favor riders with narrower feet. If you are getting sleepy toes in your Ergo 3's, you are probably going to get sleepy toes in these. The Wire and the Ergo 3 are very similar in shape and fit. That said, the Wire is a slightly more adjustable shoe than the Ergo 3, and it's significantly more comfortable (on my feet, at least). Have you tried different socks (thinner/barefoot)? How about a different insole? How about a different shoe (Shimano makes great shoes, better for wider feet). There are loads of options out there. Good Luck!
