I've been wearing Sidi shoes since I first started, and these replace a pair of Genius 6.6's from 2011. Could I have tried a different shoe? Of course, but I was pretty confident that the Wire 2's would just "work," based on my past experience, and I haven't been let down. I did take the suggestion from other reviews that I read, and I ordered the next size higher (43.5 instead of 43.0), and my new shoes fit perfectly. I have ridden about 800 miles with these new shoes, and I have't felt any pinching or discomfort. They also feel more efficient than my older shoes, and I'm not sure if that is just because they are newer, but the closures seem to hold everything just tighter, but not uncomfortably so. There were less expensive options available to me when I made my purchase, but I have no regrets.

I have been wearing Sidi shoes for a while now and these shoes are the most comfortable right out of the box. Had my previous Wire's for 7 years and the uppers started to get stiff and tight, still a good run for any biking shoe. These new Wire's are very soft and comfortable. I wish Sidi would include their memory foam insole with their high end shoes but other than that they are great!

I have been a Sidi user for over twenty years. My appreciation has never wavered, and I have tried many other brands. These are replacements for the previous version of there Wire that are still going strong--just looking a little bedraggled after many miles. And I couldn't resist the navy blue. Add in a generous CC discount and I jumped. Stiffness and pedal interface/power transfer is phenomenal. Despite this, they are comfortable, even for wider forefeet like mine. And they keep getting more comfortable as the miles rack-up. Of course, you'll want to replace the stock insoles, at least if you have higher arches, but that's true with any shoe. In my experience, the Sidi dial system is far superior to Boas which, from time to time, tend to loosen a notch when they're cranked down. These are rock solid, even after years of almost daily use, as is the case with my other Wires. Yes, they are a bit more complicated than Boas, especially when worn with overshoes. Any other time, there's an easy workaround: just leave the dial's push-button covers in the open position. Not that it's a total pain either way--more a matter of getting used to them. The repositioning of the front dial to the center of the tongue doesn't seem to make a whole lot of difference vs the previous version, although it might. But it lacks the small fingerhold that allows for maximum expansion when exiting the shoe. Now, I have to slide a fingertip under the tongue itself. Not a deal-breaker by a long shot. There are two other slight negatives that were also present in the previous Wires: they are a tad on the heavy side and they don't breathe as well as some other shoes. On hot days, the material around the heel and under the tongue retains moisture, to the point where I feel compelled to blot those areas with a paper towel, remove the insoles, and direct a fan at/into them (no heat) to prevent against possible musty stink/mold growth. This doesn't bother me one bit; given the shoe's stunning performance, comfort (and yes, 'bling') I'm more than okay with these concessions. If you're thinking of getting a pair but are holding off due to negative reviews, etc., I would recommend giving them a shot anyway. Make sure you get the size right, first and foremost, and don't return them right away if they don't immediately feel like magic slippers. They take a while to break in although, for me, this version was spot-on, right out of the box this time around. And don't be put off too much by the price. They are not cheap, but you get what you pay for; Sidis are quite literally a lifetime investment.

Years ago, I splurged on a pair of Sidi Genius 4 shoes, after having several pairs of other brands. They were something of a revelation. Even then, most other shoes in their price category had carbon soles and flashier uppers. However, the Sidis just worked, and worked for about a decade, through a couple of different bikes and pedal systems, as well as several periods of inactivity. Their Lorica uppers were comfortable from the start and wore like iron. I replaced the heels a couple of times, as well as one of the ratcheting buckles. When I got back on the bike after a layoff a couple of years ago, I realized that my trusty old Genius 4s had seen better days and decided to get a new pair of shoes. I bought a pair of one down from the top Shimano road shoes on sale. The Shimanos were fine. They were light, and probably stiffer than the old Sidis; they came with nice insoles and a couple of different arch inserts and the ability to heat mold to your foot. I didn't have any real complaints, other than an occasional numbness in my left foot. However, after less than two years, the Shimanos were ready to pack it in. The heel pad was cracking on both shoes and delaminating from the heel counter (which itself was peeling). Of course, neither of those are replaceable, so I looked to getting new shoes. As a splurge, I got these Sidi Wire 2s for Christmas. At first, I thought I might have made a mistake. They were much stiffer all around than I recall my old Genius 4s. The new upper "Techpro" materials didn't feel as comfy as the older Lorica. However, after a week of riding (about 120 miles over four rides) they were starting to feel like the Genius 4s I remembered and loved. About 600 miles in now, and they fit like a glove. I don't remember the Genius 4s having a break in period at all, but these definitely do. They also appear to be the best-made cycling shoes I've had, both in terms of materials and build quality. No sloppy stitching here! I chose these over the Shot (the Shot 2 wasn't out yet) primarily because my relatively narrow, low volume foot likes the way the instep closure strap across the top of the shoe locks in my foot. I figured if they last as long as my old Genius 4s, the extra money paid (over the current Genius 10 or Ergo 5) is well worth it for a top of the line product. They are stiff, comfy, and secure, and, IMHO, manage to look both "high-tech" and "classic" at the same time! A word on sizing -- both these and my Genius 4s are/were 45. Sizing seems pretty similar to my recollection of the Genius 4, with perhaps a bit more height in the very front of the toebox. For reference, my Shimano shoes are a 44.5. I wear a size 11 Nike or Brooks running shoe, and a size 10 dress shoe (Alden).

Amazing quality. Have been wearing SIDI's for years and just wanted a new pair of shoes with the new bike. As others have mentioned, the tongue is not the most comfortable as soon as you slip these on your feet. I manually softened the tongue and rode them on my trainer. After a couple of rides, I tested them outdoors on a ride and I found that they did not bother me at all, definitely did not dig in or hurt. I did replace the insoles with the Specialized BG insoles and found that it also made a difference in comfort over the stock insoles. Several rides now and I've found these shoe to be amazingly comfortable.

This is my 4th pair of SIDI over the last 15+ years and I'm sorry to say this relationship needs to be over. A couple of years ago I bought a pair of Shot and never really loved them. those ratchets sitting on top of the shoes slightly bothered the top of my right foot, but it was something i could live with + it got a little better w time. When i bought the Wire 2 I had a lot of hopes since the top ratchet was moved to the side. Well, what a disaster. Like two other guys suggested they hurt your ankles a lot! Wore them twice on a 3 hr ride, but there comes a point when you need to walk out of a toxic relationship. Good bye SIDI. Cycling is painful enough w/o need for uncomfortable shoes. And BTW, they run big... so big that I thought they send me the "wide" size. Question is, what shoes am I going to get next...??

Similar to Douglas S, I have been using the shoes for about 2 weeks now, and the tongue and in-step closure are digging into the front of both ankles enough to cause pain and tenderness while riding. I’m told by several others this pain goes away as the tongue gets software with use, so I’m willing to ride it out. Funny this has never been an issue with my previous Sidi’s which I’ve used for 11 years. Excepting this, the carbon sole is plenty stiff and has reduced the pain in my arches. And the shoes look super nice and are comfortable otherwise. Roll forward 2 months, and I really love the shoes. The pain in the ankles has gone away, as the shoe has become softer. It just needed to be worn a little. The power transfer is superb with the carbon soles. The shoes are comfortable and look awesome. I am upgrading my review from 3 to 5 stars. The only thing that sidi can work on is improving the cable tightening system which is less intuitive than the boa dials on my fiziks.

I have 3 pairs of Sidi's all 43.5 and fit great. These are simply too small by .5 to 1 size. Recommend going for at least half size up. By the time I received them there were no 44.0 left so will have to go without. Seemed a nice shoe not sure if they equate to the price tag but didn't get the chance to try them.

The shoes fit really well, and are very comfortable for long rides with one exception. The center of the tongue and/or instep strap presses into the front of my ankle at the bottom of the stroke. This causes bruising and pain that lasts for days, much worse on one foot vs the other. If I could figure out how to make this not happen, the shoes would get 5 stars.

I had been using a basic Giro shoe with a flexible sole you can bend by hand for years (injected nylon sole). Riding a 2013 Giant Propel Advanced SL. I feel like I have a shoe with a level of performance now that is matched well to the bike. This purchase was my third attempt on this site to find an upgrade that fit me well and locked down firmly. They were great with the two returns I made, and finally these came and fit perfectly right away. Sidi recommended a full euro size up, which was too big, I went up a half size and it was perfect. I like the tecno 3 locks for the top and forefoot a lot, better than any other fastening system I've tried. They are not hard to adjust while riding, even with a full finger glove. I cranked a few turns on the heel retention too, the shoes fit very firmly with no pain. The soles are incredibly stiff and it made pedaling seem easier too. These dont budge when attempting to bend it. My ride today felt a lot better with these shoes and I'm excited to go out again. They are expensive, but almost all the parts are replaceable, including the rubber toe piece which I wear down a lot. I want the most out of my rides and this shoe helped step that up for me, I'd absolutely recommend it.

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.
