Great boot for the price The boot is lightweight, comfortable, and wears great. The ventilation does well in the SoCal heat. Fits true to the size, I have to wear a bit thicker sock for fit. No biggie! November 21, 2014
Great boot for the street rider Solid platform. A little uncomfortable when not on the bike, extremely comfortable once you get on. September 1, 2014
Good value I've owned 7 SIDI boots. This is not my favorite but for the cost it's good. Thought I would like the MX style buckles but I was wrong. The idea is good and it works but more thought needs to go into the design. Air flow is very good. Like all SIDI boots I'm happy. August 26, 2014
Great boots! First full boot that I've ever bought, while comfortable and breathable, it's hard to feel the shift and rear break lever while on the bike. maybe I just need to get used to it, but overall i love this boot.! July 29, 2014
SIDI ST Air I've had received these boots 3 weeks prier to this review and have used them extensively, to give a brief opinion on comfort, id have to say these are the best in its class for walking comfort and ride comfort, while riding i swear i'm wearing my favorite pair sneakers their so comfortable, if standing for a while the sole of the boot is rigid and somewhat hard, so stand for a period of time sucks, but better then most other race boots, also the construction of this boot is great couldn't get better sewing seems or ease of use with their bindings also the perforated leather is amazing for air flow plus the boots have an added air port on each side so no sweaty swamp foot after a long ride, overall spend the few extra dollars cause your totally getting what you expect and pay for outta these boots... don't think about them, buy them period, their worth every penny April 7, 2014
Almost perfect It was either these or the A* supertech pro. Design: Beautiful boot Construction: perfect seams Protection features: Wow, this thing is built like a tank. Fit: This is where the A* won. The last (which is the form shoe builders use to determine size and width) is the same as my other sidis so the size was perfect. BUT 1)I could feel the Vertebra system around the bottom of my right ankle, the plastic was slightly pressing into the boot-- uncomfortable. Usually, boots take a while to break in, but this is an inch thick piece of plastic that wouldn't budge, no matter how much wear. 2)The instep is cut much wider than their other boots (I see why they have a ratchet there for the Vortice) so there was a lot of empty space there (right above the top of the foot). I'm thin, about 155 pounds, with size 45, so if you're a big guy, with thick feet, you may well fill that void, but for me it was not a secure glove-like fit. December 13, 2013
Good airflow Good airflow when it's dry. Watch out for showers. All those vents let a lot of water in. Comfortable on the road. Not at the best angle for hitting the rear brake. Overall great boot. August 31, 2013
Simply does not hold up. I have used my St Air boots for 5 track days now & the stitching that holds the heal cup is tearing on the inside of the boot. This is causing the boot to hang on my rear sets not to mention that a boot of this price should not have stitching that just starts to come apart. This is my 3rd pair of Sidi boots & I will not buy the ST airs again. June 30, 2013

RevZilla Store asked: Why did you choose this?
William P: I wanted to experience the added adjustment of the buckle over the dial on my other SIDIs. I was curious to try out the added protection as well. Yes, these boots allow much less (dangerous) movement at the ankle. Still plenty of give to ride though and enough for the track if needed! I wanted a vented boot and these move air!! Nov 10, 2014
Christopher E: I find the Sidi's fit my wide feet. I have 2 pairs of Votice, a pair of Crossfire and the Sidi GoreTex. I wanted a vented road race boot for street and track riding.

These arrived, perfect fit, just like all my other Sidi boots.

Rodger G: features Jan 30, 2014
cleartalk - a: After lots of research I fond Siidi is the boot for me, lots of protections, sliders everywhere, literally everything is replaceable on this boots... great for South California weather, vets rocks in the summer and is very good in the winter too. Jan 16, 2014
Daniel C: Great quality, styling, and fit. Sidi is hard to beat for design, quality and protection. Nov 15, 2013
David H: Had originally purchase these boots in sixe 11 and the right boot was a little tight. I was told they would stretch a little so thought they would be ok. After 5 riding session and one sore right foot decided I would have to bite the bullet and buy the next size up. Now what to do with an almost brand new pair of boots that are one sixe to small. Oh well maybe I will have some luck at next track day selling them at a discount price to try and recoup some of my money. Oct 28, 2013
josh w: needed boots to take to the race track. Aug 16, 2013

A s: I think it depends on how large your pants are. I am size 34 waist and 32 length and wear Lucky Jeans (think relaxed fit) and they just get over the top. I have to say I love these boots though, I'd find jeans that fit. Only downside is they draw attention if you are walking around the office with them. They are real squeeky and when I wear them into my office building there is no doubt everyone knows I ride (other than a couple of ding dongs who have asked if they are ski boots, WTF?) Sep 29, 2014

Andy G: Yes. I wear these boots with riding jeans & regular jeans and the fit over them just fine. The top buckle on the boot is very adjustable so they fit snug to your leg/calf for use with jeans. Then when wearing leathers that have a thick shin/knee protector you can adjust the fit. I love these boots. Sep 30, 2014

A shopper asked: Weather ranges from 30 to 90 where I'm from and I commute for the better part of the year on a motorcycle. May 10, 2013

Hombie: Non-perforated if you commute. Texas weather is similar to yours, non-perforated vent pretty well (side intake vents) and do a good job keeping my feet cool in the upper 90's, and close them for the cold mornings. If you were just a sunny day rider I would say perforated. But because of the temperature spread we both live in I think the non-perforated ST would work best for you. I am very happy with my non-perforated ST's. Jun 2, 2013

sass250: For the cooler weather you might get cold feet... wear warm socks? I think they are perfect for the hotter stuff thou!! They have flex vents right around your ankle so you notice that. I recently road in 27c (not ideal how to convert it) and the first thing i noticed was that my feet didnt get hot. So that being said they d suck if you hit rain on your ride home... I recently did and my feet got wet. May 13, 2013

A shopper asked: I'm really confused on sizing for these boots... There are a few different sizing charts out on the web.

I wear a 11.5 (USA) in a converse all star boot, anyone know if a 46 or a 47 should be my Sidi size?
Dec 27, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Michelle M: From my experience with Converse Chuck Taylor sneakers, they have always ran very long in sizing. So if you wear a 11.5 in those sneakers, I would think you would normally wear a size 12. Perhaps go to a store and try on some actual boots, not sneakers to get a feel for what your size is in boots? Revzilla also does a great job of exchanging for the right size. Dec 27, 2013

A shopper asked: I wear a 13/48 in the Sidi Sport Rain Boot. Would the Sidi ST run the same size for me, or are they are bit more narrow than the Sidi touring boots? Apr 20, 2012
Answer this · Send to friends Good question? Yes (0) No (0)
Stevan P: The ST runs very similar in size to the sport rain and it should be fine to order the 48. May 3, 2012
