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
