Sidi Vortice Boots

It was thought that the award winning Sidi Vertigo Corsa boot was the pinnacle of sport boot technology. Until today that is as Sidi is proud to introduce the next step in the evolutionary chain: The “Vortice”. The latest in technology combined with the great skill and workmanship of Sidi’s Italian based factory technicians’ blend in a whirl of fresh solutions to satisfy a rider’s desire for safety and comfort.

  • Constructed of Lorica and is lined with Teflon vented mesh. Only Sidi goes to trouble and expense of creating a multiple liner boot system in its racing boots. Lorica® is a composite micro fiber material created from strands that are so fine, each one is less than one thousandth the thickness of silk. When injected with special resins, these fibers act like natural leather skin, but with the addition of better strength, softer texture, lighter weight and better moisture protection.
  • Sidi has added a small elastic panel to aid in a smooth zipper operation as it allows a bit of movement via the elastic as the zipper passes over the rider’s ankle ball.
  • The rear upper part of the boot is made up of the following mechanisms:

    A) The TECNO CALF TENSIONER mechanism adjusts the leg circumference. Placed in the back of the boots upper, it works through a nylon wire that hooks directly to the shin plate.

    B) The TECNO SHIN TENSIONER mechanism helps the TECNO CALF TENSIONER close the leg upper on the front part of the boot. The two lateral nylon braces join the ankle joint with two screws that are protected by nylon caps. This system is reinforced with fiberglass, supports the ankle and is easy to replace. This system allows excellent flex movement front-to-back while being firm side-to-side.

  • Tecno Instep Tensioner, a fastening system on the front part of the foot, on the instep.
  • Shock Absorbing Heel Cup
  • Non-vented
  • Shin Plate
  • Gear Change Pad
  • Vortice Slider: toe slider is made in nylon reinforced with fiberglass. It is fitted with a new air intake and an innovative alloy insert.
  • Racing SRS Sole: all new sole is constructed of a polyurethane and rubber blend.

SIDI Vortice Boots 4.8 5 25 25
Careful choosing this for racing... This boot is a great fit, reasonably comfortable and great styling but be careful if using this in competition racing. Because of the complicated design my feet have occasionally been caught in the rearsets (Sato) on my race bike. For the road they are okay but for rapid gear changing in a race situation it can lose you valuable seconds or be dangerous. I have crashed in these and have held up quite well with good ankle protection. I will be buying boots with a little simpler design for my next race meet. November 11, 2015
My second pair Hit a deer last October and ended up sliding on the Tarmac for 50 feet. Boots save my feet and alkles. April 6, 2015
Perfect protection, good style When I choosing riding boots, I try many other "racing" boots, and no one can't give me feel of full protection, except this Sidi. Really love it, despite on not so good ventilation, squeaks on walking and long-time wearing. Very very very good protection - that's means what if you crashed you will not calculate in hospital saving money for leg protection, you just grow up bike and will ride further. March 2, 2015
exellent product exellent product because it's profetionality, but not made for a women, and not for a wide foot/ long liveing product October 15, 2014
Awesome boot. No regrets I use these boots for a freeway commute and for weekend recreational riding. I wear them on the bike and change into shoes when I get home or to work. Fit is excellent, protection inspires confidence. I wear a 45 shoe, ordered these in 45, and find they have a wide range of adjustability for various sock thicknesses. The calf adjustment is sufficient to allow leathers with shin guards to fit inside. Some people have said they found the fastening mechanism cumbersome. You get the hang of it very quickly. I can put these on as fast as I can just about any other. One thing I don't do in these boots is walk around a lot on hard floors or street. This, I expect, would quickly become uncomfortable. So they are probably not the best option as a touring boot. February 3, 2014
OMG!!! Simply the BEST Riding boots EVER!!!! Everything is replaceable which means it's the last riding boots I'll buy Guaranteed. One more thing PLEASE PLEASE PLEASE Buy from Revzilla.com, straight forward easy friendly process, one stop shop for all your riding needs and just an overall excellent experience. No I wasn't paid to say this but wouldn't be such a bad Idea lol. October 21, 2013
Pricey but worth it! I picked up a pair of these after trying the new A/S SMX Plus. I was disappointed in the adjustability of $400 boots and the ratchet fastener never seated right. It was always at a very high angle and the quality didn't give me confidence. I realized I would not be happy unless I had more adjustability and moved to the SIDI Vortice. If you can afford them, get them. The only thing is they do run small and the footbed is slimmer than A/S. I wear 42 in A/S and had to go to 43 in SIDI. The 42 SIDI was way too small. Also, you will have to wear long socks with these. Unless you wear them very loose, they will rub into your calves. A small price to pay for the fit and protection. Yea, they take a few minutes to put on but are your feet and ankles worth the extra 2-3 minutes? Getting in and out is actually easier than most boots, it's just getting everything locked and adjusted that adds time. Awesome boots! July 15, 2013
Bought as a gift for my husband. He loves them! Says they are awesome and the best he has ridden with. As always, Revzilla were fantastic. Product arrived ahead of time and in perfect condition, exactly what I had ordered. I will not use any other site, July 1, 2013

David W: I have ridden in light rain with no problem, but I would not expect them to stay dry in a steady rain or short heavy rain. They are not water proofed on the outside and have no Gore-Tex type lining inside. With all the external plastic pieces and screws, it would be almost impossible to water proof the outside.

Jean-Sébastien S: Hi Jacob.

Although these boots are just simply amazing, they are not made for the rain. Your feet will get wet..

Otherwise, I simply love them. It took about 2 weeks to break them in, but once they were... bingo :-)
Aug 28, 2013
Adlin R: No I don't think so because I got caught in the rain once and my sock was wet. It seem like the water got in from the side or the top I am not sure. If it not much rain it is okay, but if is a heavy rain then it will not work. Aug 27, 2013

Eric R: I've only been caught in the rain once with these boots and feet got semi wet. Once rain ended I opened up air vents and the air dried my foot thoroughly. Don't suggest wearing in rain though. Aug 27, 2013

A shopper asked: hi, would you be able to tell me which other boots have a similar fit to these? iv been trying to find some locally to try on, but because they are the top of the range ones, no one seems to like stocking them, they will only order them in for you, so i was hoping to find something thats a similar fit, to give me an idea on sizing. Jul 20, 2014

Greg A: I can tell you that I purchased the size 12.5 because I was concerned with socks on they would be too small, and also knowing that the boot sizes typically run smaller than usual.

I wear a size 12 normally in shoes, and the 12.5 does give me extra room that I feel is just a tiny bit too much. Having said that, I have no complaints about the fit. I've ridden with them for up to 10 hours and found them to be well ventilated and comfortable. The extra room becomes a mute point to me personally.

I would say the half size definelty gives more room. If you are a skier at all, then sizing your ski boot would be a similar feel to fitting the SIDI boot due to it's stiffness and fastening.

One thing that takes some getting used to is the fastening mechanisms. I'm getting faster, but they do take a minute. Once they are on, I like the ability to adjust the tension as they wear in.

I sized my bigger, and that's how they ended up fitting.

Chris C: I will say they are a very euro boot meaning narrow what ever you wear in normal shoes go one size up I wear a 10(44 euro) and ordered true to size and they're borderline to tight should've ordered a 45 cause they fine to ride in not so much to walk around in. Jul 22, 2014

Charles R: Hi There!
These are my second Vortice Boots, so I can tell you that it doesn't matter the size of your calf because you will be able to adjust your boots to your calves and your ankles. You will love these boots. at first it takes a bit longer to put them on but after a few times you will do it blind fold it and as fast!

A shopper asked: Is it possible to wear the boots inside denim/kevlar jeans? Mar 20, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Mark H: Yes but it does depend on a couple of things... the "cut" of the jeans you're wearing... and the size of your calf. I wear a relaxed fit (Harley Davidson brand) jeans and the cuffs do go over the top of the boot. My calves are defined (not huge) but when I tighten the tensioners to a comfortable position they'll fit. If you have large calves that will definitely be a factor to consider because you'll increase the diameter of what your jeans will have to fit over the top of... Measuring the very bottom of my jeans at the cuff it reads approx. 7 3/4 inches. I am laying them flat on the floor and measuring straight across. My calf is 14.5 inches in diameter. Hope that helps a bit and good luck! Apr 16, 2013

RevZilla: Generally, yes. Most Kevlar jeans have plenty of room in the legs (I can't speak for every pair though). Just as well, if you wear denim like a normal person, you should be set. I, for some reason, insist on wearing skinny jeans. I can barely fit myself into those things, let alone a beefy race boot. Mar 21, 2013
Reply to RevZilla Good answer? Yes (0) No (0)
Keith E: Yes, most boot cut jeans will have no problem fitting over the boot. The hardest part is getting it over the shin guard if the pant legs aren't wide enough. Mar 21, 2013

A shopper asked: I have a 17" calf would these boots still fit ? Jul 1, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Sarah C: i am not sure but they should, I have a 15 inch calf and have to tighten pretty good to get a tight fit.

The only problem you may have is in the ankle section. It seems to be a little tight getting my foot into the foot section but i do have pretty big ankles.

once i get my foot in the boots they are comfortable and have great safety features.

GABRIEL B: I also have a pair of SMXs and they are a true to fit for my narrow feet. The only problem I have with most of my riding boots are they cannot be adjusted. I wear a size 9.5 US and fit a 43 EU. The SIDI Vorice are a true fit being a little on the narrow side, but are fully adjustable making them the best choice in boots. I love them and will never wear anything but these boots.

Michael S: I wear a regular shoe size 9 us, this is my second pair of Sidi boots, the 43 is what fit me. However the only boot that I felt really comfortable in was the Vortice or my previous pair the vertigos for the adjustment over the foot. Hope this helps. Oct 31, 2013

Brian S: The fact that you can adjust the fit gives you the option to release the tension dials if you are walking any distance.
but I never had to. I Find them to be comfortable and the air vents keep my feet cool and dry. but I bought them for performance and the highest level of protection available. you won't be disappointed with a purchase, I highly recommend them.
