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.

Features:

  • 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
  • Nylon inner sole with removable arch support pad
  • Replaceable external shin, heel and toe sliders 
  • Nylon inner sole
  • Dual compound sole
  • High stress areas are double stitched
  • TPU shift pad
  • Perforated, Teflon treated nylon inner lining with Cambrelle lining in the toe area
  • Recessed screws used to attach replaceable parts so as to not damage bike
  • Toe slider made from nylon reinforced with fiberglass
  • Toe Slider features new air intake and alloy insert
  • Adjustable calf on the Sidi Mag-1 Boots can accommodate riders with up to an 15-inch calf diameter when measured 11.5-inches up from the bottom of the heel

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.

Amazing boots -- Happy feet
My third pair of Sidis, my first racing boot. Couldn't be happier.

Amazing protection, great bike feel, comfortable, and adequate air flow with the toe vents open.

I picked these boots specifically over the Vortice mainly because I did not skip leg day and I have a heck of a time fitting into sport / racing boots. I especially do not fit into most racing boots I've tried with zippers, particularly Alpinestars. I usually end up with an okay fit in the calves and then a lot of slack in the ankle.

Sidi's Micrometric Tecno-3 system addresses both concerns. My 16" calves have plenty of space, even with my leathers inside the boot. I do have to squeeze the boot with one hand to get the magnet to snap over the post. Then I can crank down the ankle and foot and get a perfect custom fit.

It took me about 3 rides for the boots to feel nice and broken in. The first ride in new boots is always sketchy with shifting.

I feel the footbed is slightly narrow. But I prefer the boot feeling slightly tight on the sides than feeling too long.

I'd say these boots run a bit smaller than Sidi's touring boots, so you might consider going up one size if you are making that transition.

Worth It
First off, no Sidi squeak! They start out stiff but break in after 2-3 rides. The fit can be perfectly dialed in with the ratcheting system. I usually have an issue with boots in the calf area being way too loose and feeling like I'm swimming in that area; no issue with these. Construction is top notch. This is an expensive boot, but you get what you pay for. Flexibility of the sole makes it easy to walk in. This isn't an all day walking shoe, its a race boot, but expect to be surprised by how comfortable they are. Air flow is good but not great. You won't sweat the insides out, but I'm sure a future "Air" version is in Sidi's future.

These boots are awesome!!
I got these boots a couple weeks ago and have done three rides in them as of this review. So far these are the best boots I have owned!!

I have a pair of Daytona RoadStar, Dainese TRQ, Alpinestars Supertech-R, and Sidi Cobra. I also purchased a pair of Sidi ST a while back and returned them because was just not happy with them. The Sidi Mag-1 have a nice smooth easy flex raising and lower the foot, however they are quite ridged and have very little to no lateral movement. The boots are very protective, and easy to put on. The micrometric closure system is easy to operate and allows for a quick simple custom securing of the boot to the foot. The first time using them there was a bit of a learning curve, placing the magnetic tabs, getting a hang of the rotating fasteners, but after the first use putting them on was a breeze and can be done in no time at all. The slim clean side profile of the boot, allows you to hug the bike and not catch on any external parts. No squeaking. I can go on and on about the how great these boots are!

I suffered an ankle break in the past that required surgery leaving me with an ankle that is slightly larger then the other, and these boots with their customizable securing system, high level of protection, and comfort are the best thing ever.

Fourth pair of SIDI and counting =)
I've been looking to buy the most protective boots I can get my hands on. These fit the bill.

I've been reluctant to buy the Vortice because it seemed like too much hassle to get them on and off and one thing about gear, if it's inconvenient, it ends up not being used...

Updates/upgrades to these make it so much easier to use. I do have wider feet and I wear 9.5 US in Mega series from SIDI but 10 in these. I do find them quite comfortable.

Protection seems rock solid, hopefully I won't have to find out but I do feel confident in them. I love the styling on these boots, looks technical.

Biggest takeaway I would say is the ease of usage. I would even use these everyday, given I had street shoes for off the bike.

Narrow toe box and Calf
I wear a size 11 boot. I am 6' tall and 220lbs and fit. I had to exchange the 11's for an 11 1/2 as they were too narrow. I have a wide foot, which measures 4 1/2" wide if you stand on a ruler. I had to get a ski shop that does custom ski boot fitting to heat up and stretch the outside where the joint is for my little toe.

They are also very small in the calf. When putting them on over Dainese leather pants, its very difficult to get the loops to hook, especially the top loop, even with the internal ratchet strap loosened all the way.

Once they are on, they feel good, very light, and there are no pinch points when you flex them.

I'd recommend them, but not for anyone with thick calves, wide feet.

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.

Overall a great boot
I have had these boots since they came out. Have done a mix of track and urban riding with them. Overall they are great boots.

They are protective and you feel secure wearing them. They fit true to size. They are actually pretty easy to take on and off. They are very durable. I had a very minor slide while wearing them. Aside from scratches no other pieces were affected. The air flow is amazing when the vents are open. I feel air move around my entire foot and ankle.

As is with all boots the more protective they are the harder they are to walk in or stand for long periods of time.

I wouldn't trade these boots for anything.

SIDI Mag-1 definitely worth the price
Been riding for 25+ years and was blown away by how good this boot is. I've been sold on the SIDI brand from years of mountain & road biking. This boot has the typical SIDI quality you expect and fit-finish is excellent all around. I was really amazed how good it is to ride with a proper motorcycle boot, you get much more connection to the bike and you control will improve greatly. The safety factor is another huge plus, these are plenty robust for me as a casual sport bike rider and fit under jeans well. Again, if you never had a proper motorcycle boot you will be amazed how well they improve your connection to the bike, one the the best equipment upgrades IMO. Buying from Revzilla was great, excellent information on their site and great prices plus you know they are going to stand behind their sales makes it a great place to buy from.

Better fitment system than most
I tried a few boots out before I stuck with these. What I like is the quick fit system and the fact that they went with braided steel lines covered in plastic. This way the lines are more durable. The Ratcheting system is placed in key points to really grip down on certain areas where you want it to grip down on.

Wearing them and riding with them, you feel the air rushing between your toes keeping at the very least the front of the boot cool. As for the mid to back foot area, I didn't notice much airflow or cooling there. So in terms of flow levels, I would say medium.

It will take some breaking in, as it is on the tighter side of fitment. To break them in I wore them even when I was not riding on the bike. This lets them relax a little bit and contour to your foot a little more. Other boots seem bulky and over bearing. this boot seems more contoured and streamlined. Plus with less weight, you feel less like a tank, and lets you enjoy the ride with more confidence that you have added protection.

I recommend them!

The Sidi Mag-1 had the most helpful reviews out of all the boots I looked at.

It may not have the best airflow but it seems to me this boot will be the best year-round option. I'll add a review after I've put a few miles on the.

ADAM M on Aug 5, 2014
I chose these boots over the high end Astars and Daineses because of the stream lining of the boot and the lack of zippers. Both Astars and Dainese also haven' had any major make overs in the last few seasons either. I had a pare of Astars previously and they ddin't fit my narrow foot as well as I would have liked and Sidis run a little narrow so I'm hopping the fit will be spot on.

I've owned three pairs of bike boots in twenty years, so I like to buy ones that last..... and my last pair of sidi Vertigos went for four years day in day out. So let's see what punishment these suckers can take :) They also sound like they're the most comfortable and easiest to extricate one's self from - of the super HD end of the Sidi 'serious' boot lineup.

With the vents closed, how do these feel in cold, dry weather (25-50 °F/ -4 to 10 °C)? I currently have SIDI Cobra Air which even with winter socks feel very cold due to the perforations in the above temps.
A shopper on Nov 22, 2014
BEST ANSWER: The vents do a good job keeping about 90 to 95 percent of the air from flowing in. But there is still a small gap in between the plastic fitting that holds the vent and actual boot itself. It really depends on your foot peg positioning and how your motorcycle puts your feet. I have adjustable rear sets on my Yamaha r1 so my feet are tucked close and somewhat behind me therefore I do not feel the wind as bad. But if I put my feet down to relax them while cruising or just stretch my legs I can start to feel a bit of wind slip through the crack between the boot and the plastic fitting.
Hi all, does anyone know how do these new Mag-1 compare to the SIDI ST Air in terms of ease of in/out, comfort, protection and air flow?
A shopper on Oct 11, 2014
BEST ANSWER: I can't compare but having used for a month in warm weather can say feet get air from front vents ok and boot is really easy getting off - latches look intimidating at first but once you get on to them the boot also goes on quick. Comfort is pretty good, but I added an arch support due to personal quirk....sizing is spot on if you use European sizing. This boot is pretty flexible - lets me shift easily where a stiffer boot doesn't. That's why I got them. I've worn all day two days in a row at a track event with no issues. SIDI is good - worth the price.
Is there an "air" version with perforations coming out soon?
A shopper on Jul 7, 2014
BEST ANSWER: I live in Houston, Texas. The Mag 1's have air vents by the toes. Haven't had a problem with them. They feel great.
Is the heel/sole short or tall? I'm used to riding in my work boots, so I was curious the height of the boots.
Logan E on May 15, 2014
BEST ANSWER: I'd say average sole thickness that comes on a regular shoe. Probably less than your work boots. I just measured the MAG-1 and it's a 1 inch heel (bottom of heel to bottom of heel guard). It's a 1/2 inch from sole to bottom of heel. Enough to hook onto your peg. Overall height of boot is 13 1/4 inch, top to bottom, size 41.
Do the boots make allot of noise. My current boots are so loud they drive me crazy?
Robert K on Jul 1, 2015
BEST ANSWER: First off, these boots are by far the best race boot I have ever had. I am not a sponsored rider touting a free product....I paid full price here at revzilla. Second, if you are buying these boots you should not be able to hear anything but the sound of your engine at high rpm's...preferably on a track. I have low sided (at end of straightaway) in these boots once and my foot and ankle were fine. The only damage was to the clip/wire which is easily fixed in 5 secs. Still using the same boot post low side and no issues. I may order another pair so I don't have sweaty boots on back to back track days...they are that good.
Hello, I have the opposite concern of those wondering if there is enough room at the top for large calves. One person asks is there is room for his 18" calves.

I have very skinny calves - about 13 1/2", 14" from the floor. Can the Mag 1 boots be cinched down tightly enough to feel secure. I have a pair of Sidi Gore Tex Adventure touring boots (Size 47) and they fit perfectly, although I find them to be awfully heavy and bulky, both on the bike, and walking around.

I really like Sidi boots and tried a pair of Cobras, but even tighten at the top to the max, my calves moved too much to feel secure.

Also, several reviewers recommend going up a size. I've owned two pair of Sidis, and tried on the Cobras, and 47 nails my size in all three (I wear 12 1/2 D in New Balance 990 series running shoes and they are sized very precisely.) Should I really consider going up a size?

However, my bigger concern is if the tops can be adequately tightened for my skinny calves. Thanks much.

BEST ANSWER: Hi john.

I will try and get you exact measurements if I get time. I wear the exact same size and style new balance shoe. When I speak about the size variation for the calf with these boots I explain it to people like this. The boot can handle a range variety of calls due to the design. As long as you aren't anorexic or bursting in the calf like the hulk these boots will work for you.

When I wear my dianese riding pants they add a huge amount of diameter to my calf. They fit snugly with ease.

When I wear just a pair of socks when riding in jeans (Jean leg on the outside of the boot) the boots ratchet down snugly to my ankle.

Either way I ride with these boots they are SUPER comfortable. The ratchet design really allows for increased user ability depending on what you are wearing.

The only issue I have with them as with any riding boot of this protective quality is walking any long distance or climbing stairs is different. This is a given though when you are wearing a boot that would protect your ankle in a crash.

Hi I have particularly large calf muscles (18" diameter) and find most boots uncomfortable due to the height. I ride a pair of vortice which even with the adjustment still cut into the calf with out giving full support in the lower leg shin area. I do enjoy these boots and find them comfortable use them for sports bike and touring other than the welts that appear at the end of the ride. What I need is a boot of this quality with the back that doesn't exceed 8inches high to allow movement in the calf without the pinching. Would the MAG 1 work or do I need to look elsewhere. No interested in shorty's, with the lack of lower leg support?

BEST ANSWER: This is specifically why I ordered these, because of the Adjustment in the Ankle area. As for the Upper Calf Muscle area, you can expand that to as much as you would like then ratchet it down to your liking.

I Tried the Vortice and MAG 1's and sent them back because of the extra space in the ankle area. These on the other hand had more adjustment points and allowed you to tune in the fit.

As for Flexibility, well, these dont flex much, they are a race boot for the track. You get a little bit of up and down, but nothing too crazy, it still feels tight to walk in, but Again I have only had them for 2 months, so mine may still break in some more.
I have had issues with the calf Techno fastener opening during riding. This has occurred on two sets of Mag-1 boots. Has anyone else had this issue?

BEST ANSWER: I have had no problems at all with the Mag-1 in fact I have worn so many boots over the years, The Mag- 1 has been the best ridding boot that I have ever wore. The feel and feedback from the bike is amazing. Sorry to hear about your problems with them.
Good luck
Should I buy regular version or perforated AIR version?
Elliot Y on Aug 1, 2016
BEST ANSWER: It depends on your climate. Here in Oklahoma it is hot all the time and the non perforated is adequate with the air flow to toe box.Perforation weakens the overall structural integrity and may let in more moisture when raining. iwould rather sweat a little than have to worry about either concern.
The video specifies that the Mag 1 is good for a 15" diameter at the top...Is the vortices the same diameter or larger? I have larger calves. Thanks in advance!

BEST ANSWER: No, the Vortice fits tighter on the calves than the MAG-1. I've worn the Vortice for three seasons and they were much more fiddly to get on than the MAG-1, especially for those of us with big calves. (I have 17' calves at the largest point flexed). Spending the last season in MAG-1s, I can't see myself wearing anything else.

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.
