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.

  • Teflon vented mesh liner
  • Tecno calf tensioner for adjusting leg circumference
  • Tecno shin and instep tensioners
  • Fiberglass reinforced nylon ankle bracing
  • Shock absorbing heel cup
  • Shin plate
  • Gear change pad
  • Fiberglass reinforced nylon toe slider with alloy insert and air intake
  • Polyurethane / rubber composite racing SRS sole

Please Note: Both colors feature Sidi's calf tensioner mechanism, though the Black/White boot image excludes it.

SIDI Vortice Air Boots 4.7 5 19 19
Great pair of solid boots I got both the Vortice Air boots and the new MAG-1 Air boots...the MAG-1 boots were lighter and the tensioning devices clearly newer technology but with both boots at the same price point I chose for the Vortice Air's on looks and robustness. They are more complex to put on and remove but they feel more solid once you're wearing them. That said they're heavier than the MAG-1 but I wasn't concerned by what I felt was a negligible weight difference. I haven't been on the bike in the MAG-1's so I can't speak for any differences in flexibility or airflow but I can say the Vortice Air's haven't disappointed in either of those categories. Overall this is a great solid boot and is worth the price for the performance and protection. November 4, 2015
Big Calves Should Look Elsewhere Awesome boots and awesome protection. They're also super comfortable (I ordered half size up). Problem for is I have really big calves. Sidi advertises up to 18" calf diameter - which is wrong because c=pie(d) - and i measure 15". With leathers on, I have to remove the shin guard and force the straps on with a lot of strength. I just bought Dainese leather pants and their knee/shin guard is unremovable so I had to buy Dainese boots because they offer wider adjustability for bigger calf guys. With jeans on, its easier but still a tight fit. The good news here is the string is really durable as it hasnt snapped. I imagine theres a lot of pressure on those things when i have my leathers on. Couple this issue with the strapping system and it can take anywhere from 4-5 minutes to put on per side. Aside from the fit for me, they'r super comfortable once you get them on and flow really well. You can definitely feel the protection. If you fit these, I'd definitely recommend them. July 14, 2014
Could be a little better Great boots overall. Should have ordered a half size smaller, but was already scratched in the box, so I could not get it exchanged. Tons of support and protection, but lots of room for improvement. Somewhat disappointed that Sidi didn't add more protection for the price. Under $400 would seem more reasonable for the boots. Very little break-in required. The boot is a bit larger, so I would have to wear thick socks so my feet do not swim around in the boot, but the ventilation provides enough airflow to keep the feet cool and dry. Pros: Great air flow. Comfortable even when walking around. Protects many of the important areas of the leg, foot and ankle. Fairly lightweight. Soles extremely grippy. Tons of cool stickers included. Tons of compliments. Cons: Expected more protection for the price. Tensioners seem cheaply made. Soles too grippy for the first couple rides. Somewhat complicated and confusing when putting on the first couple times. So expensive, I am afraid to scratch them. September 21, 2013
Impressive pair of boots This is the most expensive footwear I have ever purchased, and they certainly appear to be worth it. They replaced a pair of Alpinestars boots that cost maybe half as much. I have spent just one trackday on them so far, so I'm still getting used to them. The retention system is excellent, although it takes a bit longer to put these on than my previous pair which had just a zipper and Velcro. Overall sole height got my attention in the first session, as I had difficulty getting my foot under the shift lever, but I later got that sorted out. The venting and perforated material also make for a much cooler foot than my previous boots. July 22, 2013
Ultimate Protection My first serious pair of motorcycle boots, and oh what a pair they are. Great sole feel, excellent range of motion in the ankle, amazing styling, replaceable insert for front of boot sole, and everything is replaceable (EVERYTHING, even the entire bottom sole). No fiddling with any quick tie system or lacing system. Drop your foot in, and adjust the three tensioners-you're good to ride. I went for the black/yellow for visibility. I wear a size 48 normally, but decided to order a size 47-like the idea of having a snug fit-no tightness issue at all. Can't recommend enough! April 18, 2013
Lacking medial support NOTE: I have not worn these boots while riding. I share from an off bike perspective - for return purposes - against the Alpinestars Supertech-R, and Dainese Torque RS Out. The ample lateral ankle bracing doesn't connect to anything except leather on the medial side. If your heel touches down on the medial side of the ankle, or if something gets tangled that causes a medial twist, the boot offers - in my opinion - inadequate support. My last track crash involved a medial twist. I was not wearing these boots, but after purchasing and testing on my still raw ankle I'm unfortunately unconvinced they would perform. You can easily bend the ankle to the inside well beyond its natural range with no mechanical stop or slowdown. I wish this were different. Why Sidi didn't continue the plastic heel around to connect to the medial side brace mystifies me. They are a beautiful boot, that offer a lot of support, and so many other features, I wish it were not so. When compared against the Alpinestars Supertech-R, or the Dianese Torque RS (in/out), they lose. Both these alternative boots performed better in my crude, twist-my-raw-ankle-by-awkwardly-pushing-it-in-unnatural-angles-to-the-medial-side-yet-not-on-a-bike-(now I need Advil) test. So I'm returning the Sidi boots. However, I'm still torn between the Supertech-R and Dainese Torque RS. The Supertech seem to provide the most amount of support, and they are ridiculously comfortable (they really do feel like slippers), but they're a bit clunky/bulky. Once again I wish the Italians had made a boot feel as technically supportive, but the Dainese ever so slightly don't: the ankle support is external, which wouldn't be an issue except that the upper portion of the boot fits a bit loose nullifying the supportive effort (maybe with huge calves your ok?? Even with the calf adjustments at their tightest they're still loose on me), and their lateral sliders are much higher on the boot, risking a touch down of heel rubber before the slider can do its job. I hope this helps someone in their decision, and doesn't just frustrate. Good luck! March 26, 2013
Feels like air! wakka wakka ;-) Putting them on it felt like a pair of Ski Boots. Complicated but rather worth it. The first steps I took I almost fell forwards as the flexibility is nothing like I expected. So free!!! The Dorsiflexion and Planter flexion is amazing. The soles almost felt invisible but standing on the pegs of my bike there so solid. To walk in them is so easy. Only draw back is I can't seem to get the top ratchet tight enough (I wear my Ski Boots tight but these arnt Ski Boots) The leather pants with built-in shin pads might fix that? Also the front vents were a bit off center, fixed with a screw driver in 1 min. Its still winter in Wisconsin so I haven't ridden in them yet so I can't judge the airflow. Overall a stunning piece of technology with amazing flexation! Plus definite limits. February 11, 2013
Awesome Boots! These boots are great. Only downside is price. I'd say go up a size when buying January 7, 2013
