Wire 2 Carbon Cycling Shoe
The Wire was Sidi's top shoe for a number of years until the relatively recent release of their range-topping Shot. Now, the Wire sees some updates that improve fit and comfort while giving the shoe a sharp new look. Like the Shot, the new Wire 2 Carbon Cycling Shoe has the lower dial relocated to the top of the tongue for a more comfortable fit with equal tension across the whole foot. The instep strap has been made a bit narrower too, with improved flexibility and the addition of padded edges to further improve comfort. The all-new microfiber upper features a textured finish for a unique look, and is available in some striking new matte colorways.
Sidi shoes are well renowned for their comfort and stiffness, but Sidi hasn't attained its dominance by resting on laurels and leaving innovation for its competitors. While many shoe brands will outsource it's dial closures to BOA, the Wire 2 utilizes Sidi's own Techno 3 dial. Most notably, it allows for adjustments of each of the shoe's instep and forefoot buckles and is significantly more intuitive and easier to do while in the saddle. Loosening each buckle is a simple affair — you can pinch both buttons on either side of the buckle to unwind the line closure, or you can toggle each button for extremely precise incremental adjustment. Tightening the shoe should also be familiar: just open the buckle's switch and wind the buckle. Sidi uses a supple, low-friction line material to keep the buckle action smooth. Not only does the Techno 3 make the shoe's overall aesthetic even cleaner, but it also allows for an even greater degree of micro adjustability and fit consistency across the entire shoe. This ensures that you get the perfect fit every single time you buckle up for a ride. And for those who prefer as snug a fit as possible, the shoe's Soft Instep Closure System has generous padding for supreme comfort with tight buckles.
Sole duties are handled by the Vent Carbon Sole, complete with a replaceable, polyurethane heel pad to improve walkability, and a replaceable, integrated toe pad/vent cover. The sole isn't only impressive because of its efficient power transfer, thanks to its light weight and stiffness, it also aids in all-weather comfort. Using integrated vent and air channels, it allows for exhausting pent-up heat as well as increasing air flow. The vent can be opened in the summer to keep your feet cool and closed during those long base mile winter days. Sidi paid special attention to the layup of the carbon fiber and it features opposing angles that maximize stiffness while allowing for a small degree of controlled flex in the toe area. According to Sidi, this carefully designed flex biomechanically relieves stress on the plantar tendon and helps promote circulation.
Also returning from previous top-shelf offerings is Sidi's vastly improved Heel Security System (or HSS) to keep your foot positively planted in the shoe. By means of a small Allen key, it's an adjustable, rigid composite band that closes the shoe more securely over your heel to anchor it in place around your Achilles. So, no matter how much power you're pouring into the pedals, your heel will stay in place inside the shoe. It's a detail that allows you to cinch down the straps of your shoes less tightly — giving you more comfort along with more security.
With a degree of engineered flex in the Carbon Sole and a secure and slip-free heel, you won't have to worry about hot spots. And you don't have to worry about heat in the rest of your feet, either, with the Wire's combination of Techpro Microfiber and ballistic mesh — giving you comfort, breathability, and durability.

The fit on these shoes is classic SIDI. It's a SMIDGE tighter on the whole and the toebox than my 2011 Sidi Dominator 5 MTB style shoes, but on the whole trying them on one after the other its barely noticeable..
The tecno 3 system is awesome, puttting them on and taking them off is a snap and I love the strap across the top paired with the wires for the main area fit wise. Though I do wish you could microadjust tighter and not just loser; it really wasnt an issue.. Usually as a i ride I end up needing to tighten a bit on my old shoes, but that wasnt the case with these.. just supremely comfortable.
My very first ride with them was a 50 mile trek with 2000 ft of climbing, and having suffered from achilles injuries on both sides i loved the adjustable heel retention which i tightened a smidge and didnt agitate my achilles area at all.
I love the stiffness of the sole and the venting. It's just enough for me and I'm someone who's always warm and the ride went from 70F to 94F as the day went on.. one of my vents would not open so they are exchanging them out for me which shoes the commitment to customer service IMHO.

Really disappointed. I had previously owned a pair of sidi wire shoes, which I’ve loved and put upwards of 10,000 miles on. When it came time to purchase a new pair, I didn’t think twice about opting for another pair of the latest Sidi wire shoes. This time, i took the opportunity to try the lates technology, in the form of the “Wire 2.” The Wire 2 has relocated the BOA dials to be directly on top of the show, which precludes the wearer from being able to tighten the shoe any further than the width of the BOA dial, which leaves the shoes a bit too loose for my taste, or from what I have been accustomed with my previous shoe. Additionally, I had taken for granted that the sizing from one Sidi shoe to the next would be identical, and this simply has not been the case. The Wire 2 seems to run at least a size or possibly two sizes larger than my previous shoe. I had the shoes for more than 30 days before I rode with them, and thus, they are no longer returnable. So, I am unfortunately stuck with a pair of $400 shoes that are too big, despite being marked as a new incarnation of the same model I had previously owned. My advice to prospective buyers would be to absolutely try your shoes on in the home before mounting cleats or using outside. You might also consider ordering your traditional size in addition to a size down, for comparison’s sake, and then returning one or both if you are not satisfied.
