If you need airflow and protection, look no further
Alright, I waited quite a bit to write this review because I feel products should be battle tested. I've been wearing these boots for close to 2k miles now and I think they are, without question, the best boot when it comes to airflow and protection.

Firstly, they flow a ridiculous amount of air. The level of airflow would lead one to believe they forgot to put on the boots at all. It's really quite amazing. They flow as much as air as a mesh running shoe, if not more.

They are, without a doubt, an excellent boot when it comes to ankle, foot and heel protection. I have put the toe sliders to use no less than a half dozen times on each boot and they're still in pretty good shape. I'd anticipate having to replace them, depending on how you ride, every 40-50ish times you get a toe down for a prolonged period. I'm not talking about brushing the toe on the pavement, I'm talking about your toe is on the pavement for the better part of the turn. Either way, just tuck that toe in a little bit once you've touched and they'll last you longer.

Comfort wise, these boots are superb. I am a size 10.5 in an Adidas, Asics, etc, and a 43/44 in a dress shoe. I initially ordered the 44 expecting them to fit like all Sidi boots. The 44 was a problem for be because my foot was sliding around, I didn't have a good sense for where the heel, toe and shifter were while under way. Not good. I sent them back for a 43. In the 43, I can feel my toe hitting the front of the boot when I'm walking off the bike. However, once on the bike I have absolutely zero discomfort and no longer notice my toe hitting the front. So much so, in fact, that I honestly can't recall if my toe touches the front or not when my foot is on the pegs.

These boots are not meant to be walked around in. I leave a pair of shoes at my desk in the office or bring a pair with me in my tailbag so that's not such a bad deal. The only thing that really irks me about these boots is that they squeak and squeak a lot. The squeaking noise comes from the joint where the Achilles protector pivots. If you leave the boots unclipped while walking around, the squeaking will cease. I haven't tried lubricating the joint yet, that's my next step. FWIW, the squeaking has gradually gotten worse, not better.

Overall, these boots are amazing. If you require almost-race levels of protection and astounding airflow, look no further. They're pricey, sure, but what's your ankle worth to you? They're comfortable, too, but don't expect to wear them around when off the bike and be perfectly comfortable.

Also, I commute in these boots as well as wear them for track days. They're sexy but also quite wide at the top. If your jeans aren't baggy or aren't a rather wide boot cut, you will end up having to tuck the jean which, in my opinion, looks MUCH better with these boots thanks to the protruding heel.

Great Fitting Boot
I owned a pair of SIDIs several years ago that were great. Then I had to go and crash test them on a high speed high side. The grinding from the long slide left those SIDIs unusable. However my feet and ankles where left in good shape. The past two seasons I have been using my backup boots from a good company ($400 boots), but just hate them because I have little feel of the pegs.

So, the wife bought me the SIDI STs for my birthday. I have not put any track time on them but they fit great and feel glorious. I am sure I will cut 5-6 seconds off my lap times with these.

Yeah I like SIDI boots, others don't. Find what you like and ride. I recommend SIDIs and Revzilla!

Perfect Track Day Shoe
Did a trackday at California speedway and this was my first time wearing the new ST boot. Without question, the most comfortable boot I have ever ridden in. I'm an A-stars guy all the way, but the Sidi boots fit snug and allow for easy manuevering when upshifting and moving around on the pegs.

Between sessions I found them easy to walk around in when unfastened, but once you lock the fasteners for your next round of laps, you can feel that the boot isn't going to go anywhere in the event of a get-off. The 44 fits a US size 10 1/2 like a glove. If you're thinking about it, just pull the trigger and get a pair. You won't regret it.

This boots is simply awesome.
FIrst of all would like to say that the kind of service standard you are giving is exceptional. A 11/10 on that.
The boots are very easy to get in and out. Though will need a bit breaking in. The feel is awesome and will definitely recommend the boot. Have the air version and the amount of air it circulates will make you easy and not sweaty on the bike.
Sizing is spot on and 43 as adviced by Revzilla fits me perfectly.
The only downside or as i should clarify there is bit of squeaking from the exoskeleton when i walk. Maybe due to boot being brand new.
Otherwise simply perfect.

Got the boot`
Finally pulled the trigger on these. Great quality. Very lite. They feel like they weigh less than my tennis shoes! Nice sturdy sole. Couldn't be easier to get into. I wear a size 8.5 to 9 shoe and bought the 9.5 size. Fit perfectly and are easily wide enough for my EE size foot. Very happy with the purchase. Revzilla service was outstanding as always.

Top quality Italian design and features
Definitely worth the extra cash for these boots. The zipper, Velcro and latching systems work together for a perfectly adjustable fit. I'm not planning on crashing in them, but they're some of the best protection, if needed.

Great boot for the price
The boot is lightweight, comfortable, and wears great. The ventilation does well in the SoCal heat. Fits true to the size, I have to wear a bit thicker sock for fit. No biggie!

SIDI ST Air
I've had received these boots 3 weeks prier to this review and have used them extensively, to give a brief opinion on comfort, id have to say these are the best in its class for walking comfort and ride comfort, while riding i swear i'm wearing my favorite pair sneakers their so comfortable, if standing for a while the sole of the boot is rigid and somewhat hard, so stand for a period of time sucks, but better then most other race boots, also the construction of this boot is great couldn't get better sewing seems or ease of use with their bindings also the perforated leather is amazing for air flow plus the boots have an added air port on each side so no sweaty swamp foot after a long ride, overall spend the few extra dollars cause your totally getting what you expect and pay for outta these boots... don't think about them, buy them period, their worth every penny

Great boot with superior ventilation
I bought these boots b/c another rider I know smashed up his ankle and made me question whether I had enough protection with the street boots I had.
I chose these to get what appears to be superior protection, but I got some other benefits as well. These appeared to offer the protection I wanted for $100 less than Sidi's top of the line (and harder to put on) race boot, and it looks like they do just that.
I had to get these one size smaller than my previous Sidi's. I had a pair of 42's that fit very well, but had to go with 41 in this boot as the 42's were too large everywhere.
The design is excellent - get them right once, and from then on, the boot doesn't need another adjustment.
The range of adjustability is excellent.
The boots are very comfortable except for some pressure points on the outside edges of the toes and edge of the foot but I think any boot would be since it has to be rigid there. Very little break-in required - my first track session I kept missing my shifter like the boot was shorter than my old ones, but a comparison showed they were not and by the 2nd session, I had adjusted to the difference. If this Lorica material holds up as well as leather, then it is really an awesome material.
Ventilation is the best of any boot I've ever worn on a bike - when you start moving, the air moves like you aren't wearing boots at all!

Great track day boot
If you want all the protection you need for normal track days without spending as much as the pros, this is the boot to get. Great style. Easy to take on and off. Not too difficult to walk in. doesn't get too hot.

They did squeak a little after a crash on the track on a rainy day, but that might be my own fault... Can't hear it over the exhaust anyway
