Quality Protection/Performance
As a Firefighter/E.M.T with many years of experience I have responded to many motorcycle crashes. Injuries to feet/ankles are some of the most common and severe that I have seen. These boots are not inexpensive by any means but the level of protection they provide is well worth it. First, with three ways to secure these boots to your feet (side zipper, velcro, and clamps) they are not going to come of with ease. High speed impacts really do tend to blow your boots off. If your foot protection comes off at the initial impact obviously they can't protect you during subsequent impacts. Second, the external bracing and padding provides protection against side to side forces and impacts focused on the ankle, arch and the heel. The soles allow very good feel on the pegs. They are just a little awkward to walk around at first but you'll get used to it right away. The venting is nice. Riding in the Texas heat, these boots allow enough airflow through to keep my feet from overheating. In my opinion these boots should be required equipment for any aggressive street rider or track day racer. Spend the money protect your feet and ankles ( it's very hard to walk without them.) By the way did I mention that I currently have three screws in my right foot from a 55mph motorcycle impact back in 1993 that blew my 8" lace up logger boot off my foot. I was lucky to even be alive after that crash, but was blessed enough to be able to continue my profession and my riding passion. Many others have not been so fortunate . I haven't been riding without high quality protection/performance gear since and never will ( ALL THE GEAR, ALL THE TIME ). I highly recommend these boots to any rider who is looking for the high quality protection and performance that aggressive riding demands..

Awesome boots crash proven
Well i bought these boots and sadly ive already crash tested them at 30mph on a low-side after i hit a patch of gravel :( and my feet came out completely unscathed. Although it was a pretty minor crash if i hadn't of been wearing these boots my ankles would of been screwed up. I actually have a video of the crash on youtube which ill link over on the right side of the review.

Nice boots but not as protective as their appearance suggests
Ordered these and am sending them back.
Fit is great- I have another pair of Sidi's in 44 and these fit exactly the same, and true to size (I wear size 10 New Balance). Protection isn't what i expected from the appearance though. The plastic bracing pieces aren't very stiff and you can fold the boot in half pretty easily just with your hands so these really won't stop a lot of torque if your foot hangs up in a slide or impact.
I wound up going with Supertech R's which aren't a whole lot more rigid either unfortunately but the bootie design keeps the protection closer to the ankle and feels more secure.
These are definitely beautiful boots and they do offer decent protection and great style, just not rugged enough for my taste.

great boot for those who want good protection
I love this boot. After getting that out of the way, let's get down to it.

These boots are great boots. The protection is great, they are comfortable for me, (I have larger calves and wear a size 43) they are slightly in the narrow side, but not enough to really make a difference. The only time I notice it is after a long day of walking around, but as soon as I hop on my bike I never even notice it.

When riding, which is what these boots are designed for, these boots shine. They offer everything needed for riding. A shifter pad, sliders on almost every available surface, a good sole... They do squeak when walking but who cares?

The only thing I would like to see is a way to adjust the fit at the ankle like the vortice has. They can get a little warm on 85°+ days while sitting in traffic, but when you are moving at any kind of speed, your feet stay fairly cool. If you live in a warmer area, or don't plan on doing any riding in the wet, get the ST airs. All in all, it is a perfect boot for those who ride the street hard and want high protection with style and functionality at the same time.

Boots are very good quality and very comfortable. True to size for the most part, I wear a 10 - 10 1/2 shoe and a size 44 fits very well with just a slight bit of extra room. They are every light weight and break in easily. Also replaceable toe pucks are a plus

Style, comfort, protection & street cred... What more could you ask for?!?
Not my first purchase from Revzilla & certainly not my last! I live in Australia & have found dealing with these guys to be cheaper, quicker & easier than getting my stuff locally! (go figure!) The Sidi ST boots are awesome offering Italian style, comfort & protection all at a great price. I highly recommend them if you're after something a little more than your average boot. Enjoy!!! Ps, they turned in around a week... Sweet!

Get these boots!
Very impressed with this boot. I wear them on a StreetGlide and on a KLR 650. I was pleasantly surprised with how well the vents cool off my feet. Close the vents and they keep cold air and rain out long enough for me to get to a bike stop. And they're comfortable enough to walk around Sturgis with a smoked turkey leg in hand.

Awesome boots!
I've road raced one season with these boots. Durability-wise the threading for some of the armor on the inside ankle area (the area that rubs against the rearsets) wore away and the armor began to separate. This became more and more a problem, and eventually the armor began to catch on the rearsets (preventing me from moving my foot to operate the shifter, which resulted in missed shifts...not good). To remedy this I wrapped this area in gorilla tape, which seemed to work, but for boots this price, this is unacceptable. Not sure what Sidi can do to remedy this, but maybe this use-case is a bit extreme (repeated road racing), not sure if these boots are really targeted for this kind of usage. I chose these boots for how quickly you can put them on, and remove them. This makes them VERY convenient compared to something like the vortice.I had 1 very high speed crash in these boots, I slid into a tirewall feet first at least 30-40 mph+. Protection wise, I have to say they did their job, I've had A LOT of crashes, and this was the worse impact my feet have ever experienced (smacking a tirewall at speed). My left foot hit first, at an angle, which resulted with my ankle attempting to roll (twisting the ankle), I feel if these boots did not have the bracing system my ankle would have been utterly destroyed. I did have a nasty contusion on my ankle but x-rays showed no fractures, a week later I was walking normally again. Thank you SIDI!

Great Boots, Get Ready For Sizing Exchanges
There is likely nothing I can tell you about the aesthetics of these boots that the review video from Revzilla hasn't covered. Just watch that. What I can shed some light on, perhaps, is sizing and riding with them.
I attempted, as I always do, to following sizing charts and user reviews to avoid having to ship anything back. Not because of the monetary loss (Revzilla is dope when it comes to exchanges), mostly to avoid the wait and to try and not inconvenience them because of my mistakes in ordering incorrectly. I failed. Sorry RZ. 2 size exchanges.
Normally a 10 US. Extremely small in the toe. Size up to 11, still uncomfortable. 11.5 seems too big, but the room in the toe makes it bearable. Maybe look into heel inserts or pads. Tucking the leathers or jeans into the boot seems to alleviate some of the sliding. Obviously not planning on walking in them much. Just something to consider when ordering.
You'll likely notice the armor hitting on your pegs when stopping, and shifting up or down takes practice - but it is definitely part of the trade off when purchasing boots like this. I've been able to get most of my jeans over the boot if attempting to not look like a racer/elitist.
If you want a race boot with plenty of protection I would highly recommend - just keep in mind that this is function over form. Hope that makes sense.

Naaman B on Mar 17, 2016
I had heard good things about SIDI boots from friends. I tried a pair on and that was all it took to get me to switch. Very comfortable, although a bit narrow in the heel for my feet (narrow heel and wide forefoot. A generic drugstore heel cup makes for a perfect fit. They're snug, but in the right places and I feel very protected. They're easy to walk around in, but I probably wouldn't go for more than 1/4 mile. All in all, great boots!

I chose the SIDI ST boot because of the experience I had with my other SIDI boots. I have been wearing a pair of SIDI "On Road" Gore Tex adventure style boots for about two years now and they've been great. I anticipate the same build quality and performance from the ST model.

Hey guys. Can you tell me if these boots are water proof ? Thank you!
A C on Jun 13, 2016
BEST ANSWER: I have had mine for about a year in Hawaii (where it rains with no indication or warning) as Long as the vents on each boot is closed and the are tight on your legs feet. I never had wet feet.
which are better boots comfort wise Sidi st or Aplinestars smx plus ?
A shopper on Aug 19, 2013
BEST ANSWER: I can't speak to the Alpinestars, but the Sidi ST boot is very comfortable. I have a pair of Sidi sport touring boots without the external protections and honestly the STs with toe, heel, and ankle hardware external is just a s comfortable on the bike. They are less good for walking around, but fine for social/food/etc stops when out riding. The STs are every bit a day long boot.
Would you recommend this for regular sport riding? Not necessarily track riding. Also, I know Anthony mentioned that SIDI replaces soles on some of their boots, is this one of them?
Matthew C on Oct 15, 2015
BEST ANSWER: Hey Matthew....
Yes!
I absolutely love these boots as I feel that they are comfortable enough as a daily riding shoes with more than enough protection to hold up on the track and if in an unfortunate accident. These SIDI boots are my second pair and honestly think will be the only brand I will buy in the immediate future. The one of many reasons I chose these is for the additional lateral protection for the ankle and all the additional strategically placed sliding pads. These are WELL engineered.
Although I can't answer with 100 percent confidence I do believe that most parts are replaceable.
You won't be disappointed if you buy these....
Cheers
How do these boots feel with the vents closed in dry and cold weather (30-50 degrees)?
A shopper on Nov 22, 2014
BEST ANSWER: These boots are either airy, or very airy. Which is to say in cool weather with the vents closed there is still a good breeze coming through, more than you'd experience with any non-vented boot. In cool weather if you want to really have warm toes you'd have to consider a gore-tex or similar sock.
I am new to these kinds of boots and leathers. I just received today, both my SIDI ST boots and an a* Motegi suit. Are these things compatible? I can't put the leathers on the outside of the SIDI boot, as they won't zip up (and it doesn't seem to me that is the way they should go anyway). But I also cannot put the leathers inside the boot, as the boot will not zip up if I do - not even close. I can only assume that the a* boots are shorter and designed differently than the SIDO boots? Anyone with experience on this? Also, the shin guard in the suit extends into the boots as they are so tall. I am at a loss as I can find no one else commenting on such a problem in the reviews here and elsewhere. Any advice would be appreciated. I am getting ready to return the boots but would like to be sure it's not just me.
Thomas K on Feb 4, 2015
BEST ANSWER: well, in the end I think I just decided it's new leather and I just need to work it for a bit. But, I am left curious as to what the advantage is of the boot's interior mesh when I have my lower leg wrapped in thick leather. Anyway - insights are appreciated, but I believe I'll stick with the boots and look forward to the day when it gets a little easier. I don't have thick calves, and the boots are the correct size for my feet. So, I assume it will all work out.
Just got my hands on a new pair of Sidi ST Boots. Phenomenal product but the left side air vent is rubbing horribly on the side of my foot. Backed out the screws that hold the ankle brace on which helped a bit but am not sure it's a cure. Is this area likely to soften during normal break in? Lot of money to spend on this boot if it doesn't . Also, how do you shorten the strap on the cam buckle? Read something somewhere about popping the strap out in order to make the adjustment but would like some further direction before I risk breaking it. Thanks. RevZilla rocks!!!
Brian K on Feb 19, 2014
BEST ANSWER: Unless your left foot is wider than your right, you may have a faulty boot.
Just took a look at mine and the air vent does not come anywhere near my foot, my boots are extremely comfortable, can wear them all day at the track.
I would try on another pair just to be sure.
The strap needs to be popped out of the grey plastic piece that says sidi on it and then you'll see that it moves freely for you to adjust. Just pull it softly outwards from the 2 small tabs holding it in place.
How tall are the boots from the heel of the footbed to the top?
Victor S on Dec 1, 2014
BEST ANSWER: I believe my are size 43 11 about 3/4" from footbed heel to top of back of boot!
Are the Sidi Vortice toe sliders compatible with the Sidi ST?
William C on Apr 7, 2014
BEST ANSWER: Hi . Don't know as the Sidi Vortices have holes for ventilation in the boots + toe sliders.
According to their size charts, SIDI seems to use European sizing and run 1/2 size bigger... If I'm a size 8 USA, will the size 42's fit me or be too big?
A shopper on Aug 29, 2011
BEST ANSWER: I have found when it comes to Sidi sizes, it's best to order a little larger than you might think. For example, on U.S. sizes, I am normally a size 12, and my shoes are a little loose (I like them that way). When I ordered the Sidi Way Rains, I ordered a 46, thinking they would be nice and snug. They were too small. I had to return them (easy) and order a new pair. The 47's are listed as a 12.5, and they fit perfectly.

Based on that experience, I suspect the 42's will fit you just fine. If they don't, Revzilla will allow you to return them and get a different pair. I don't think you'll have to go that route, but it's nice to know you have it available.
are the sidi st's a step under the mag 1's?
A shopper on Jan 2, 2016
BEST ANSWER: Yes, but they have slightly different purposes. ST probably have more protection, are heavier, and are bulkier (especially on the side where the boots meet the pegs). The Mag-1 has slimmed down construction.
