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.

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.

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!

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.

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

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.

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!

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

Good value
I've owned 7 SIDI boots. This is not my favorite but for the cost it's good. Thought I would like the MX style buckles but I was wrong. The idea is good and it works but more thought needs to go into the design. Air flow is very good. Like all SIDI boots I'm happy.

Protection and the changeable hard / protective parts.
Q U on Jul 7, 2016
I wanted the next price point performance level up from the last pair that I still have and this was it.
I really wanted them in red to match the suit and the bike but the AIR option only comes in white and black and the perforated leather is important. For this early season track vacation they're a little cold at times depending on temps but on the other end of the spectrum without the AIR option can get very hot and uncomfortable.
SIDI is the best....feet down.

These boots are great. They move a lot of air. Great protective gear.
Ian B on May 23, 2015
I wanted to experience the added adjustment of the buckle over the dial on my other SIDIs. I was curious to try out the added protection as well. Yes, these boots allow much less (dangerous) movement at the ankle. Still plenty of give to ride though and enough for the track if needed! I wanted a vented boot and these move air!!
William P on Nov 10, 2014
I find the Sidi's fit my wide feet. I have 2 pairs of Votice, a pair of Crossfire and the Sidi GoreTex. I wanted a vented road race boot for street and track riding.

These arrived, perfect fit, just like all my other Sidi boots.

After lots of research I fond Siidi is the boot for me, lots of protections, sliders everywhere, literally everything is replaceable on this boots... great for South California weather, vets rocks in the summer and is very good in the winter too.

Great quality, styling, and fit. Sidi is hard to beat for design, quality and protection.
Daniel C on Nov 15, 2013
Had originally purchase these boots in sixe 11 and the right boot was a little tight. I was told they would stretch a little so thought they would be ok. After 5 riding session and one sore right foot decided I would have to bite the bullet and buy the next size up. Now what to do with an almost brand new pair of boots that are one sixe to small. Oh well maybe I will have some luck at next track day selling them at a discount price to try and recoup some of my money.

Will boot cut jeans fit over these??
A shopper on Sep 29, 2014
BEST ANSWER: I'm not sure. I wear these over suits. I would guess yes, since they are smaller in diameters than other. Regardless, Revzilla does offer returns.
I typically wear a wide or extra wide shoe. Are these going to give me issues with being to narrow?
Jack H on Feb 9, 2015
BEST ANSWER: I usually wear wide shoes too. Can't wear normal nike sneakers without ripping them. Ordered the Sidis true to what I wear in leather dress shoes and found the fit to be perfect even for full day wear.
Will boot cut jeans fit over these boots??
Jonathan R on Sep 29, 2014
BEST ANSWER: I think it depends on how large your pants are. I am size 34 waist and 32 length and wear Lucky Jeans (think relaxed fit) and they just get over the top. I have to say I love these boots though, I'd find jeans that fit. Only downside is they draw attention if you are walking around the office with them. They are real squeeky and when I wear them into my office building there is no doubt everyone knows I ride (other than a couple of ding dongs who have asked if they are ski boots, WTF?)
Weather ranges from 30 to 90 where I'm from and I commute for the better part of the year on a motorcycle.
A shopper on May 10, 2013
BEST ANSWER: For the cooler weather you might get cold feet... wear warm socks? I think they are perfect for the hotter stuff thou!! They have flex vents right around your ankle so you notice that. I recently road in 27c (not ideal how to convert it) and the first thing i noticed was that my feet didnt get hot. So that being said they d suck if you hit rain on your ride home... I recently did and my feet got wet.
I'm really confused on sizing for these boots... There are a few different sizing charts out on the web.

I wear a 11.5 (USA) in a converse all star boot, anyone know if a 46 or a 47 should be my Sidi size?
A shopper on Dec 27, 2013
BEST ANSWER: From my experience with Converse Chuck Taylor sneakers, they have always ran very long in sizing. So if you wear a 11.5 in those sneakers, I would think you would normally wear a size 12. Perhaps go to a store and try on some actual boots, not sneakers to get a feel for what your size is in boots? Revzilla also does a great job of exchanging for the right size.
I wear a 13/48 in the Sidi Sport Rain Boot. Would the Sidi ST run the same size for me, or are they are bit more narrow than the Sidi touring boots?
A shopper on Apr 20, 2012
BEST ANSWER: The ST runs very similar in size to the sport rain and it should be fine to order the 48.
