Only a sprain
I bought this boot because it was the most comfortable boot for my foot, and if I'm honest I have always like sidi products from my dirt bike riding days. Anyways I ride a lot of canyons faster than I probably should. One day I crashed my bike lost the back end on a patch of oil braking into a turn at over 70mph, I slid feet first into a boldered hill my right foot struck first exploding the rock. But after x-rays at the hospital I only sprained my foot. If I was not wearing these boots I probably would not be walking today. These boots might seem somewhat expensive but when it comes to what you need them to do they perform at the highest level. I could not recommend them more.

Excellent TRACK boot...
Ok, so, I went big for my first set of "Track Boots".... rather than get a $150 pair, I got these because I wanted the exo-skeleton type of hard armor. These absolutely fit that need.
They are as comfortable as you can ask for while in the bike. They provide impact, abrasion, and thermal protection nicely. The metal cam lock at the top of the calf is a bit hard to adjust, but they are really secure once adjusted.
The only things that I can note as a negative is the loss of tactile feel on the levers, and the less then flexible look when walking in them (off bike obviously). Let's face it though, if you are wearing these SIDI ST Boots on a dancefloor, you have other issues you need to address first. Besides, in a good, proper fitting track suit, we all have that hunched over duck waddle walk anyways, so what's the big deal with adding a stiff ankle gait to the ensemble?

So far so good. I did have a hard time getting them to zip over my leathers. I also noticed that it takes some effort to get my foot into the boot, but once it's in, the boot feels about a half size too big. At first I thought maybe it was just my foot, but I don't have the same problem with my Alpinestars boots. Overall, they are pretty nice. I am a little on the fence about the cam buckle thing being on the INSIDE of the boots too. I have to keep those in mind when swinging my leg over the bike. I feel like it's only a matter of time before I scratch it up.

Sick Boots
I had Sidi Vertebra on in a recent nasty wreck. They absolutely kept my feet from being demolished but I still have some problems. I wanted an upgrade in protection. These are legit. They feel bomb proof compared to my older Vertibra and offer protection from different types of potential problems in a crash. They are a bit stiff and bulky compared to the Vertibra. And I do recommend those as well but these are next level. Need to size down but these are the boots!

Safe and stylish
Get a Size bigger. Easy to put it on once you get used to it. Not that much Airflow. Good to ride in lower temperatures.
I got in Red and gets a lot of compliments
Need to get used to it before you go for first ride.

Pretty comfortable and look great!
I wear a size 11 shoe, so on the safe side I went with the 11.5 and they fit well! The toe doesn't too much wiggle room, but it comfortable for me because id rather have it fit than be loose. The heel on the other hand leaves a good bit of room, so I'm debating putting a heel insert into the boot, otherwise its a great fit! Very sturdy boot with protection all around. The buckles adjust around the calf so you can loosen or tighten to fit jeans or riding pants.

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.

Great boots and great protection
So, I may be a little biased about these boots, but they are likely the reason I didn't break my ankles in a recent low side crash!

About two weeks after getting these boots, I low sided, and while the boots suffered some scratches and scuffs, the bruises on my lower leg show where the impact force was redirected by the boot, and frankly I'll take a bruised leg over a broken ankle!

While I only got a little bit of time in these before the crash, I will say they are quite quite comfortable. For me this is rare to find in a moto boot of any kind as I have 12 4E width feet, despite my very wide feet, they fit great!

Also, despite crashing them, they are still very much wearable and will get lots of use for a long time to come!
