SIDI ST Boots 4.8 5 53 53
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! July 7, 2016
Love these boots! Great style and great protection. Awsome external TPU armor and a great color scheme make this boot as functional as it is eye catching. June 14, 2016
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. April 14, 2016
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! April 11, 2016
Dragonslayer boots These boots look amazing, especially the black and red model. I absolutely love how they look. Jeans fit over them pretty well, provided they aren't too tight to begin with. I find myself tucking my pants inside, because it's a bit more comfortable. If you're coming from a more flexible boot, these feel entirely inflexible, and don't plan to walk more than half a mile in them. They're not great for normal walking. They're also bigger than a lot of other boots, so it will take a little to adjust to how they fit on your pegs and get under your shift lever. That said, they're amazing looking and I feel like my toes, ankle, foot and shins are as protected as humanly possible. I imagine a car could run over my foot and it'd be fine. I'll trade poor walking performance and a little bulk for this kind of protection, especially when it looks like I'm wearing dragon slayer armor.. November 9, 2015
Love them I ordered these boots from Rev for two reasons. One no sales tax and two you earn cash towards your next purchase. Thank You Rev for that. Now for the boots. These things feel and look awesome. They are comfortable and I definitely feel like they will protect me in a crash. I have not crash tested them but I would definitely buy them again when needed.

Best Boots Out There Fit true to size. Very comfortable to ride in. Very stiff at first but once you break it in they work great, only took a couple hours of walking around the house. June 11, 2015
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. June 8, 2015
