SIDI Mag 1 Boots

The Sidi Mag-1 Boots feature an innovative internal brace system constructed from carbon fiber for the ultimate in support and light weight design. The Mag-1 Boots weigh in at 4.4 pounds each, or 17% less than the Vortice boots. An all new Micrometric Tecno 3 magnetic closure system makes adjustments quick and easy and the internal brace system provides ankle stability and flexibility.

The rear upper is made in polyurethane and is assembled to the boot with two screws: one on the outside under the TECNO-3 Magnetic mechanism, the other on the inside which holds the micrometric adjuster strap. The screws support and block the internal support system which is made ​​with carbon fiber beams, making up the frame of the boot. This system allows excellent flex movement front-to-back while being firm side-to-side. An all new Micrometric Tecno-3 magnetic closure mechanism is easy and quick to use as well as being highly adjustable and light in weight. The TECNO-3 Magnetic closures close the boot with an extremely resistant steel wire, that is hooked to the clip with the aid of a magnet.

Sidi has created an incredibly solid boot with well-chosen design elements and materials to create a very lightweight, yet ultra-protective race boot system.


  • Arch and Achilles areas are covered with Sidi’s exclusive elastic textile and injection molded polyurethane comfort panels
  • Arch area utilizes two TPU bands next to the TECNO-3 Magnetic closures, for a maximum support and wrap of the arches
  • Asymmetric and shaped shock absorbing heel cup, smooth and flat inside for more adherence with the bike, with shock absorbing system in the back and outside
  • The shell and the shock absorbing system are replaceable through a screw  and  an interlocking system

SIDI Mag-1 Boots 4.9 5 30 30
H.O.L.Y. C.R.A.P. Dude seriously the air hole in the front of the boots is the bees knee's to me. I can wear this boot all day and not have tired feet. Never owned a pair of road boots, for the most part im a dirtbike guy so we all know how those boots feel. these are insainly light, they aren't too tight nor too loose so in my opinion this is amazing. I pretty much walk around on ski's since my feet are so narrow. if you have super fat feet don't even think about the regular size.i swear it felt like they broke in within a week, never expected that. I do feel like my feet are protected, plus they look cool as he** (at least I think they do) they aren't too pricey which was a big issue when it came to boots. your average joe over here cant afford 10,000 dollar boots so these fit just right with my wallet. keep it up SIDI you guys rock. July 12, 2016
Best Boot on the Market These are the best of the best. For comparison I have: Dainese Torque D1 Air Alpinestars Supertech-R Vented (2015) Alpinestars Supertech-R (2016) Supertechs take 5 min to put on, MAG 1's take 30 seconds, are infinitely adjustable, & give much better support. Alpinestars feel soft, pliable, and cheap (but are comfortable), MAG 1 are robust and very comfortable. I got side swiped by an idiot on the fwy, broke my knee (crush fracture). These saved my ankle/foot without doubt so i can speak to the protection first hand. May 4, 2016
SIDI Mag-1 Stiff at first, however after a couple of rides, they have broken in nicely. Good protection and very comfortable. December 7, 2015
Interesting new design for Race boots. Had these on my radar since they came out, finally got em, very pleased with the new design and essentially perfect fit. I am a 45 in Sidi's, got 44's once and they are too tight and I don't think they will ever break in. I wear 11 in virtually all shoes and like just a tiny bit of air space around my feet for air circulation. If you have ever owned Sidi's then you know the toe box can vary a bit between models, but this one has a more narrow heel and perfect amount of space around the forefoot. The toe vent is a blessing, they should have that on all Sidi models, otherwise this boot may have ended up more swamp inducing like some others I have. The boot is kind of a funny feel, like a thick wrap of rubber compared to other models, but the wrap design allows an excellent ability to dial the fit, more latitude than the Vortice IMO, that one promises a lot but is designed for a wider foot and the adjusters just reach a point where they don't want to cinch any further, so it still feels wide and loose on narrow feet. I really don't notice the mag-1's feeling less bulky or better for walking, but they don't grind all over the rearsets and swingarm as badly as the vortice. Finally, the vortice screws on the soles tend to thrash OEM footpegs as well, so that's another reason I like the mag-1's. I will continue to use my perforated vortices for the summer and the non-perf mag-1's for cooler weather. I wouldn't say the mag-1's are better than the vortices, only that they favor a narrower foot and have several areas that are improvements. But, the general feel of riding with the vortice's is quite nice if you can tolerate a bit of wear on the bike and the boots. In the end if you can have both, I think you will find the mag-1 an interesting new design that is a win in many areas and I have no regrets on the purchase. October 7, 2015
Awesome boots These boots wrap your feet and lower legs in a lightweight cocoon that feels connected to the bike. It is easy to find the shifter with the top of the boot, and great through the soles when the balls of the feet are back to the pegs for cruising or high speed corners. These are easy-on, easy-off, and comfortable from 45F to 95F air temp. These ran a bit smaller than an old pair of SIDI boots, and about a half size smaller than my SIDI bicycling shoes. These boots don't appear to come in half sizes, so round up, not down. September 8, 2015
Best boots I've ever worn Best boots I've ever owned. They are a bit stiff at first, but once broken in they are perfect. I went a half size up (I wear a 10.5US sneaker, and went with the equivalent to the 11 in EU size). They fit great. I'm glad i didn't go smaller because they would have a hard time fitting over my suit legs (Dainese Aero Evo). Great comfort, very light and compact shape, great styling (everyone loves them), and feel very protective. I would recommend these 100%. Worth every penny. July 20, 2015
This has become my everyday boot I've been riding daily for 10 years and in that time I've gone through a lot of boots. These are by far the most protective pair I've ever owned. My other boots feel about as protective as flip-flops compared to these. These are exceedingly comfortable despite the protection. I now wear them on every ride even just running around town. I had to go up a size because this boot is narrow. Highly recommend. May 27, 2015

The new kid is back in town. This is the Sidi Mag1 in my right hand, as you can see it, and the theme is flexibility, lightweight and streamlined in a brand new design for 2014. On the other side of the table, I have the classic Vortice and really the Vortice remains right at that same level, same price point but it's set up a little bit different compared to what they've done with the next iteration from the Mag1. Now, Sidi worked with Bautista, Cal Cruchlow, they worked with Andrea Dovizioso. And they worked with the GP-level riders and really found where they wanted to go with this new boot, outside of a dramatic restyle, was they wanted to shave weight from it and make it a little but more flexible for the rider.

So, each boot now is seven ounces lighter compared to a Vortice, what we saw the pros wearing previously. They've also done, you're going to see it right away, is they've internalized your vertebrae system. So, on this boot again it goes with the weight saver, you get this big, rigid structure all the way outside on the lateral side, on the medial side going all the way up to the Achilles, what they've done with this boot is they've actually used two aircraft-grade carbon-fiber supports running from bottom to top on both sides of the boot, but they're internal and they allow for a little bit more flexibility, a little bit more feel. And you can see the streamline of this boot, again, they shaved nearly a half a pound off of each one combined. And I have the black/white version of each one. So, again, from a positioning standpoint, you're Vortice probably still is a bit stiffer, a bit more bomb-proof, but the pros want something with a little more tactile response and feel.

Notice how they shaved down the heel cockpit here? You're getting halfway shock absorbing heel counter that on the inside is a much more low profile than what< we've seen previously. Again, going with that streamlined appearance. But a lot of the rest of the boot is very similar in its function, meaning performing at the highest level, full-speed, for MotoGP level crashes and catering to a pro-level rider around that $500 mark. Now, before I get into every change and every nuance, let's talk quickly about fitment. I believe this booth will be more comfortable for most riders. They've even made it more adjustable up here at the top. You're getting 15 inches of adjustable circumference around the top of the boot, that's brand new. They've also changed the way it interfaces with your calf.

The foot bed is going to remain relatively similar, and you'll still get that hardcore race sole from Sidi but you'll notice on the bottom that they've removed that piece that was replaceable, on the dual-compound sole. but again, looking at the arch and looking at the Achilles from a Fit standpoint, again removable arch inside of the boot but on top now you're going to get a bit more breathability and you have this area of elasticated nylons which has these big TPR's over the front of it and these TPR's along the back. Again for allowing,more flexibility.

Now, there's no hard start and stop from a hyper-extension, hyper-flection standpoint, but you do have those carbon-fiber rods that do run up and down the boot for that internal rigidity. Keep that in mind guys, and if you're concerned how it's going to rock, remember European sizes but again Sidi's been playing here in the U.S. long enough, will ship for free, so don't worry about it. You can always give us a shout if you're concerned about that fitment and remember, I want to hear your gut reaction.

Now, let's dive back into the nitty-gritty and really work this Sidi Mag1 against the Vortice, front to back, top to bottom and highlight all the changes besides just the overall style as we go. And remember guys, the baby brother to both of these boots, which you really can't go wrong with, is the ST, which is just a different, it's around that $400 dollar mark, but if you're already making that investment, both these guys are just head and shoulders above that level of protection. Now, looking at the toe, you're going to instantly see a dual compound with a replaceable alloy slider here on the toe box. It's nylon with fiberglass reinforcement, reinforced toe as well, you have that similarly on both the Vortice and the Mag1. Notice a refined shift panel, recessed stitching, you're going to see it without and both of these boots are going to have micro-fiber, that techno-micro, which is synthetic leather all the way out. When you use synthetic leather versus natural leather, you eliminate all imperfections, keep that in mind.

Now, looking at the Techno-3, magnetic system. Big change here on the Mag-1versus the Vortice. Notice this is different now, instead of nylon mono-filament, now you're, using coated stainless steel. And the cool part about it is you have a release on both sides, versus one sided on these bad boys, and what happens is it actually the Techno3mag system, see that magnet right on the bottom there? Just kind of holds it in place; it doesn't go anywhere. It got rid of a lot of the fuss on this guys and they managed to use lighter weight, smaller stainless steel to keep it in.

So, if I completely undid this boot, right? I'm gong to snap my adjuster up, I'm going to give myself some slack, I'm completely undoing it, right, going all the way to the top of the boot, again allowing, it to release. Remember, 15 inches of circumference up here along the top. You're going to see it doesn't go anywhere, it stays in place, you just kind of pop it in. I put my foot back in there and I'm ratcheting it down . Notice how it slides right into place and again that magnet lines up there perfectly.

And you'll see how they use that larger area of TPR across the instep here to give you better coverage and make sure that this is going to stay hardcore and in place and hold up to abuse, because remember, look at all the screws in the outside here, screw, screw, screw, screw, screw, screw, you're going to have a lot of places that are replaceable within this boot. And just like the Vortice, these are heirloom products, they're not meant for one season, or even three. They're meant to really hold up and allow you to make that lighter weight investment of just replacing a slider or two and keep it running for you season after season after season, whether you're racing, whether you're crashing or whether you're just doing track days.

Now notice, as we move here into this hinged area, if you popped off the cap of this slider which is a medial or it's a lateral outside slider, you'd see a screw that holds this carbon-fiber structure in place, that run all up and down the inside and outside. Again, big departure from the vertebrae system on the back of the Sidi. And notice, we do have that heel counter on the back here, you're going to see there is an area of reflective. Moving back up, the shin plate is completely re-designed now. Lighter weight, smaller, out of harms way, and you notice if you come in here really tightly the whole interior of this boot the medial side is much flatter, much lower profile, meant to create a much more seamless area of contact with the inside of your faring or your bike in aggressive scenarios rather than having a raised point here, a raised point here.

Again, that was one of the big feedback pieces that came back from the Motor GP level. Now, you can see those both on the inside here and remember; low-profile in the inside of the heel as well because that area is going to be stopping right there where you have the area of the counter that is rubber-backed with that shock-absorbing zone. Notice, too, medial slider, and again, dual-carbon fiber struts up from there, down from there, keeping it in place again, limiting range of motion adding sturdiness, adding rigidity but again not getting in the way. And the nice part about this boot too is by allowing a little more flex, you actually give your knee a little bit more range of motion, you're actually giving yourself a little bit more room for escape if you do get into a situation where some of that torsion, or twisting is going to be relayed up to your knee.

Now, what I'm going to do here, I'm going to open this bad boy up from the inside out, done that a couple of times, show you how easy that is to pop this off just like that. And when I start to open it up you're going to see that the lining looks like the classic Sidi Cambrelle lining but it''s actually not. It's Cambrelle in the toe box and around the foot, but up here toward the ankle towards the calf it's actually going to be perforated nylon that has a little bit more thickness to it. It's actually more comfortable it has a much more a 3D effect to it, so what it's going to do is it's going to promote better air circulation, promote better wicking. It's actually going to be more comfortable overall and you can see all the way down into that bad boy how much that breaks. This is going to be very easy on and very easy off. You notice there's even a stretch panel right there for better range of motion. The other thing I want to call out is look at the back here along the top of the calf.

Now on the Vortice it goes all the way up, and you have another techno-micro adjuster or a Techno-3 adjuster right there You have it on the side there, you're eliminated one, you're saving some weight here but on the back you're going to notice they have that high point of TPU that goes up. They've given you another area of soft TPU that has some padding built into it and what that's going to allow you to do is make sure that your calf never get chaffed or cut up because this area of TP is never really going to break in and that's okay because it's meant to be supported. So they're giving you an area of soft plastic to interfere or to interface with your leg so you're not going to have any trouble there, and you can see the way that this is put together.

They didn't skip, but they shaved right where they could, they eliminated excess where they could and they simplified where they could and for me I'm a fan of that approach especially if it's going to offer more tactile response to the rider and again, being a little but more light weight, you're going to produce less fatigue over time with this boot which will be the Mag1 over the Vortice, especially if you're talking about 25 laps around the track. So remember the Vortice and the Mag1are really brother and sister products. One is not better, it depends on what you're looking for.

If you want ultimate bomb-proof, you go Vortice. If you want to sacrifice a hair on the stiffness and protection side, just a hair and get a little but more streamlined and light-weight and a little bit more response from a boot that's going to be a little less rigid, that's where you go Mag1, and again, we're seeing that trend at the pro level. Keep that in mind, guys. Still a bunch of sizes and a ton of colors for each one, you really can't go wrong and the baby brother for both of these guys is going to be the ST.
